Ask the simple question but do not seek only the simple answer.  The simple answers below are in italic and relate to the more complete answers above.

Is planning permission needed for a timber building?

Whether a building requires planning permission or not depends on the location, size and use to which it is to be put.  To build a separate building on land for use as a home requires planning permission.  Building a garden shed may not require planning permission but is not suitable or permissible under planning law to use as a home.  It is best to check, ask an expert or the local council.  New homes do require planning permission.

Are timber buildings economical?

The costs of constructing homes are similar for all types of construction.  No significant savings can be expected for building using timber.  The principal difference between building types are typically confined to external walls.  External walls can constitute less than thirty percent of total building costs, the remaining seventy percent includes foundations, drainage, roof, windows, doors, electrical installation, plumbing, fitted furniture, groundworks and decoration.  A garden shed compared to a home may appear economical, but costs offered should be examined carefully.  Timber used in construction in Ireland is typically imported.  The most economical buildings use materials most suited to the local environment and locally available.  Timber in some cases may be more economical.

Do I need an architect?

Building Control Amendment Regulations of 2014 (Ireland) require of those building homes to assign a certifier and a builder who are competent and qualified to provide their services.  There are no qualifications recognised or controlled in Ireland for builders or tradespeople (2019) other than relating to heating and electricity.  Assigned Certifiers and Designers must have recognised qualifications.  Engineers, Architects and Building Surveyors are the only professions permitted to take the responsibility of assigned designer or certifier.  These all require years of education and training and the practitioner must be registered.  In building anything that is subject to building regulations it is vital that a suitably qualified professional be appointed.  Architects, Engineers and Building Surveyors offer different skills.  To optimise the design potential the most qualified is an architect.  Structural design and underground drainage require the services of an engineer.  Building Surveyors should be familiar with regulations and the building science, as should any professional offering the services of Assigned Certifier or Designer.  It is the building owner’s responsibility under law to appoint someone they know to be competent.  In this regard it is important that the principal professional or project leader be as familiar with all requirements as possible.  Unless you are an expert, you do need an expert.

Of the many systems for timber building, how do we choose?

The simple answer to this is that you don’t.  Unless of course you have the qualifications to choose.  Marketing material examined offer, single solid log walls, glulam walls, twin wall systems with insulation filled cavities, timber frame with solid log external skin, cladding, metal roofs, timber floors, double glazed windows and so on.  There is a large choice and cost alone should not be a deciding factor.  Technically, many of these are no more than garden sheds.  These are typically unsuitable as homes, offer little insulation or moisture control and often have costs that relate only to the bare building only.  Foundations, electrical installation and plumbing is often not included.  The prices quoted are for simple garden sheds.  Some of these are offered with insulation.  Of the systems inspected, the levels of insulation are often very low and neglect the effects of moisture movement through building structures.  A simple garden shed often has similar internal temperatures internally to that externally.  In such a situation there is little thermal movement that could result in damp.  The capacity of air to hold water increases with higher temperature.  More worrying, this capacity reduces with lower temperature.  As air moves from warm to cold spaces, or from inside a home to outside, it reaches a condensation point at which the air temperature can no longer sustain the levels of moisture.  This can occur within the building fabric and often does.  Quality timber technology (or any quality building technology) controls this movement of moisture.  Much of the insulated timber technology inspected on site for low cost buildings does not address this tendency.  Interestingly, those simple garden sheds that have been insulated often increase the risk of this moisture movement impacting negatively on the structure.  Where this occurs within the structure, it is called interstitial condensation.  The build up of moisture in hidden parts of construction can be calculated and needs to be controlled.  This can be controlled by ventilation, after carrying out calculations where condensation is most likely to occur.  This will inform as to where ventilation should be.  Where this ventilation is not provided, moisture will build up.  This can result in black mould on wall surfaces, or moisture in the hidden parts of walls.  This in timber construction can be detrimental and in cases dangerous.  The Berkeley balcony collapse in California on investigation was deemed the result of inadequate structural ventilation resulting in dry rot (Serpula Lacrymans).   Dry rot completely destroys timber and thrives in the absence of ventilation.  Much of the structural detailing examined in cheap timber construction supports the development of dry rot.  The least effect of this is seriously reduced life span for buildings so constructed.  As with Berkeley, the most serious result can be fatal.

Understanding of the science of building is vitally important as buildings become more complex.  The complexity arises due to the need to conserve energy.  Passive methods are those where no active measures are taken, such as the physical build up of external walls, floors or roofs.  The science relating to the movement of moisture must be understood.  The science relating to active solutions such as ventilation systems must also be understood for as building fabric becomes more efficient, room or space ventilation becomes more important.  These factors render simple technologies for the most part obsolete.  The best choice you can make is to choose an independent expert.

Are timber buildings environmentally sustainable and energy efficient?

The levels of insulation under current building regulation with reference to TGD Part L (Technical Guidance Document Table 1, the maximum elemental U-Value for external walls is 0.21 W/m2k (watts per metres squared kelvin).  To achieve this with simple log buildings, the factors that must be considered includes the durability of the timber used and the thickness of the wall.  Sustainability requires durability.  For instance, cedar is a highly durable timber which offers excellent insulation properties.  In order that a solid timber building complies with regulations the thickness of a cedar wall would need to be in the order of 420mm.  For comparison with more widely available timber species, a solid less durable spruce wall would need to be about 600mm thick in order to comply.  Cedar is considerably more expensive.  Also, thicknesses as would be required are not generally available commercially and would need to be ordered specially from very specialised suppliers.  Factory assembled elements that offer similar performance can be available but again generally only on special order.  To reduce this thickness would require the addition of insulation, which when carefully designed and applied could result in a wall thickness in the order of about 250mm.  Less than this is possible, however the costs and technical complexity increase dramatically with any thickness below 250mm.  Any wall therefore less than 250mm is likely to fail either in terms of moisture damage or insulation rating.  Walls of 250mm if poorly designed may result in failure.  Timber is a sustainable building material and if correctly detailed and constructed can last generations.  Energy efficiency requires high levels of insulation and air tightness.  Sustainability when applied to any building material is directly proportional to the resultant life span of the building.  It is therefore possible to have an environmentally unfriendly concrete building being more sustainable than some timber buildings.  Timber buildings if designed and built correctly can be highly sustainable and energy efficient.

Are timber buildings simple to construct?

Some marketing implies that timber or log building is a cost effective and technically simple way to build a home.  As noted above, timber construction can be simple technically though with generally unavailable 420mm thick cedar logs would be extremely expensive.  Cutting logs to fit snuggly takes experience and skill, as does placing them.  This can be technically simple but difficult to execute.  One spruce log section of the size noted above 300mm long could weigh more than two hundred kilograms.  Buildings complying with current building regulations are not simple to construct.

Reliable information required to sustainably and economically construct buildings is not easily available.  Misinformation abounds!  Technical and scientific expertise is required to evaluate the plethora of offers available.  Many marketed building systems fail it appears as a result of an absence of the expertise required.  Some do offer sustainable solutions, those who do are happy to be exposed to professional and expert evaluation.  The construction of garden sheds as homes being tabled as a viable option is an insult and injury to society and the absence of proper control worrying.  It falls legally on the building owner to ensure compliance and the building control regulations require local councils to examine fourteen percent of buildings being constructed.  This offers a security to those being inspected by the councils.  It relates to fourteen percent of buildings that are notified to the council and has no bearing on those being built outside the rules.  The recourse to the councils in dealing with buildings illegally constructed is to enforce their removal.

In brief, let the independent professionals do what they do, and enjoy the benefits.

This is a Norwegian log cabin during construction.  The timber used is 'malmfuru' a pine that grows in mountains above an altitude of 1200 metres.  It has similar insulation and structural properties to Cedar or Larch.  This image shows base logs in the order of 300 to 400mm in diameter shaped to provide about 220mm thick external walls at their narrowest.  In order for this to comply with current building regulations, it would need insulation added.  This is a single skin very specialised construction fully assembled in a factory setting prior to being delivered to site.  The timber, being possibly the largest species available in Scandinavia is felled under licence from virgin forests, it is not farmed timber and is typically from trees well over 100 years old.  Due to it being a limited supply this is an expensive timber.

This is not optional despite criticism or the seeking of an extension of time on these requirements becoming mandatory.  This standard has been notified for almost ten years.  Sufficient time for the collective consciousness to take stock, particularly for professionals.  However, it also appears that ignorance of this requirements is common.  The RIAI (Royal Institute of the Architects or Ireland) cites in the Code of Professional Conduct under article 1.15 “Whilst an architect’s primary responsibility is to his/her client(s), he/she should nevertheless have due regard to his/her wider responsibility to conserve and enhance the environment.”  Due to this requirement, I do not claim to be an environmental specialist for to be so is a requirement of my profession.  This requires architects to be familiar insofar as is possible with the requirements of legislation generally relating to the environment but also with the science relating to building and the environment.  A detailed knowledge of emerging technologies, both passive and active, used in the built environment that can enhance the natural environment is therefore mandatory.  It at least means that an architect should be familiar with technologies that have the least impact on the environment while realising clients dreams and aspirations.

How we live, travel and work all impact.  Many of my colleagues cycle and use public transport as do I.  I also use private motorised transport.  I admit that I have a passionate interest in machines, but I also realise that I must reduce the amount of energy that I use in both my personal and professional life, as must we all.  In our buildings low energy lights were introduced for the purpose of reducing the energy used.  The results have in studies proven less effective than hoped.  Our grandparents and parents were inclined to turn lights off, turn the emersion off for the purposes of saving energy, or perhaps saving money.  They also spoke about living within our means.  Our means today is too often based on our money.  Notably, our capacity to pay.  Environmental means are less inclined to be considered.  It is not uncommon for lights to be left on, for TVs to be left on, for electrical emersions to be left on and for energy to be wasted.   Hybrid cars are becoming common, many of these are high powered and in fact not very economical.  One of the most economical cars that I ever owned was built in 1968 (NSU Prinz 4, tuned for economy, 60mpg +).  While there are more economical cars today, there are still few on the road.  We simply chose comfort and convenience rather than economy or sustainability.  As we demand more luxury, sustainable developments have less beneficial impact.  We chose to justify this by driving hybrids.  La Ferrari, Lexus RX450h as examples of hybrids are neither economical nor sustainable.  As many have become accustomed to spending a certain amount on fuel or energy, both in our transport and our homes, we are happy to spend this and can extend the use we put to these technologies not despite but because of their improving efficiency.  There can be no significant benefit in doing this for the environment.  Production of sustainable power needs to precede its use.  Any increase in the use of even the most sustainable energy source is easily negated by excessive use.  Data centres and electric vehicles are likely to demand huge amounts of energy.  Rampant use of these technologies will require that we burn fossil fuels.  Energy use needs to reduce.

Our buildings comfort will improve with the best sustainable technologies.  It is vital that we choose actively that this be the case, it is nZEB legislation.  To choose technologies that use 20% of the energy that we have used before while achieving the same result is admirable.  In choosing less together with more sustainability, we can reduce the impact further.

Architect are required to assist in these choices while achieving client’s intentions.  Client’s intentions are the primary goal of architects, but only with careful regard to the environment.  According to the RIAI Code of Conduct, this is not an option.  It is the remit of architects to make the process as effective as possible in every regard.

The control of unwanted solar gain using solar panels to generate energy in high-efficient modern buildings will reduce operating costs and energy use.  Local and therefore more sustainable sourcing of this technology must also be considered.

I have carried out a study using examples of projects and references to various guidelines and legislation highlighting the need for control. While the control measures had been in place on some of these projects, these had at the time not been implemented.

Building Regulations.

For any building to be sustainable in terms of longevity it must be constructed with regard to certain scientific truths. Ireland is a particular climate where the conditions suitable for interstitial condensation may be constant. Water vapour condensing within the structure is common which leads to deterioration conditions developing more quickly in Ireland than in other climates. In timber construction this can be detrimental. The science relating to interstitial condensation is the same the world over and an understanding of it is vital if problems are to be controlled.

The Building Regulations, Technical Guidance documents cite the following:

B.S. 5268 cites B.S. 7543:1992:2003. Superseded by B.S. 7543:2015.

This document categorizes buildings relative to their life span based on intended use.

Table 1. Categories of Design Life for Building.

2. Maintainable.

3. Lifelong.

Last for the life of the building. Examples: Foundation and structure.

It is therefore clear that conditions within any structure are sustainable to the extents noted above. While the Technical Guidance Documents are Guidance only, the intention of these is that the buildings comply with the Regulations. The Regulations are those highlighted within the Documents in grey boxes. The guidance demonstrates common means by which these regulations may be achieved. Where there is a technical variation to these guidelines it should be possible to demonstrate compliance by reference to other standards. The building control relied on since the introduction of these regulations, (the ceasing in effect of the council bye law system) was the duty of the professionals and contractors involved. It appears that the failing of the system was that there was no clear requirement of clients to employ suitably qualified professionals. This resulted in a condition whereby anyone could provide construction and design related services, this remains the case where building contractors are concerned, it is no longer the case where architects are concerned. The use of the term ‘architect’ is controlled in legislation.

Any significant increase in costs consequent on the BCMS system is therefore more the result of a failing in the superseded system than it is in the new system. Where projects previously had been carried out correctly with sufficient specification and inspections by suitably qualified professionals the costs would largely be similar to today, and the projects would likely be successful. The additional costs incurred in the current system would therefore be confined to the preparation of documents and submissions to the authority. These are based on information that should be available for the development of any project subject to building regulations, this includes projects that are exempt from planning control. In my experience, this amounts to approximately 5 days work at most. While this does add cost, it is not significant in relation to the full services that should be provided in any event. The significance as noted relates to these services not having been fully provided for prior to the 2014 act.

Building Control and Building Regulations are distinct from one another. The need for building control applies to anything in the built environment. The need for Building Regulations arises in order to ensure Building Control by placing a legal responsibility on all those involved in the building process, including clients.

Timber construction.

Timber frame construction is subject to extensive damage consequent on the absence of correct detailing, construction and expertise. There is a contention in Ireland that timber construction is relatively new and therefore that expertise is limited. This is no more true in Ireland than in any other country, even countries where timber construction is a long standing tradition. I have inspected timber frame houses in Ireland built in the 1970s which were correctly detailed and constructed, the expertise was clearly available forty years ago. The absence of expertise being applied is a product of a combination of factors. Lack of proper education, lack of care and an assumption that to employ suitable experts as an unnecessary cost all contribute to problems. Education relates to the need of clients to understand that the experts offer a valuable resource, it also relates to CPD (Continual Professional Development) being practiced by those experts. The R.I.A.I. is the appointed governing body of architects in Ireland, any architect registered (whether a member or not) is subject to the Code of Professional Conduct. With relation to the Code of Professional Conduct, this applies under Section 6 of The Building Control Act, 2007. All registered architects whether members or the R.I.A.I. or not are subject to this Code. This is not the case with Building Contractors, though it is proposed. Does this place a higher responsibility on registered professionals? I recently interviewed principals of construction companies. The proportion who understood interstitial condensation was of concern. It was considerably less than 50%. When presented with details Fig. 1 and Fig. 2 many were unable to comment on the interstitial condensation risk. One who had been educated in the country where timber construction is traditional and who had a college education in construction technology and management was amongst those unable to comment. The requirement for CPD is a condition of members of the CIOB relating to the building industry. The CIRI, an official registration body noted as being supported by government has prepared a Code of Conduct which requires members to be sufficiently informed or to employ sufficiently informed persons to provide services. Membership of the CIRI is increasing and there is mandatory CPD requirements for members. It is as yet not an appointed body under any building control regulation.

Fig 1

Fig. 1 shows a condition on site where a steel ‘I’ beam was supporting rafters along the line of a slopping valley gutter. There is positioned internally to the beam and the rafters insulated plasterboard with an integral vapour barrier. The wall plate to which the rafters are fixed effectively creates an unventilated space in a location where due to the cold bridging effect of the steel beam is highly likely to develop interstitial condensation. In this case I believe it is highly likely that the wall plate will over time rot, seriously weakening the roof structure.

Fig 2

Fig. 2 shows a condition inspected where the external blockwork / brickwork is not been fitted with adequate drainage or ventilation. This is a common condition where the required cavity is provided with less ventilation than needed, or in cases not provided with any ventilation. This will lead to the deterioration of the timber structure.

This highlights the difference between building regulations and actual building control. The majority of building control is carried out on building sites and it is therefore fundament that those operating and in particular managing building sites are sufficiently informed about the technology being employed. Fig. 1 and 2 are illustrations of conditions where interstitial condensation is likely to cause problems. Fig 2 on inspecting buildings throughout Ireland has been a common error over a number of years.

Fig 3

Fig.3 shows a condition inspected where the external finish has been fixed to the timber structure with a separating layer of tar paper. As with other examples the insulation used is soft fibreglass with is subject to settlement. The base plate is fitted onto a masonry wall separated using bitumen. Note: the base plate is fitted centred on the masonry wall limiting sufficient drainage of the weathering layer. In addition to the absence of any interstitial moisture control, there is a risk of ponding adjacent to the sole plate. In this example the structure was seen to be severely deteriorated.

Fig. 3 is a more serious detail where inspections have revealed serious problems arising out of both penetrating moisture and interstitial condensation. This is a problem that is repeated throughout Europe. Ireland has a climate where interstitial condensation can be a daily issue throughout the entire year and is likely to develop problems associated with Serpula Lacrymans (common dry rot) or Coniophora Puteana (common wet rot). Dry rot develops in slightly damp unventilated spaces, these are generally not the result of penetrating damp, leaks of heavy rain. Dry rot develops in conditions more similar to interstitial condensation where the moisture content is lower and there is inadequate ventilation. It spreads more rapidly and due to being in unventilated spaces not subject to high levels of moisture it also spreads invisibly. Wet rot develops in higher moisture content areas, often penetrating damp (rain water and leaks) the bottom of drained cavities when blocked, and is often very damp or wet to the touch. The base of timber stud walls, to where interstitial condensation had drained if not drained clear of the building yields both types of rot depending on the specific conditions. Dry rot may be more inclined to develop in less damp areas. Ventilation is the primary control of dry rot while preventing moisture ingress or high levels of moisture being retained in the structure is the primary prevention of wet rot. There are of course solutions that may be applied for the control of both. This does not alleviate the need for correct preventative detailing. Fig. 3 shows a detail of a wall, with no ventilation gap between different components of timber construction. Fig. 2 shows an image where there is a gap but it is not ventilated. Both these conditions provide instances where interstitial condensation builds up at the junction of the components or in the gap. There is no means to dispel the moisture content through either evaporation or drainage in both cases and the conditions for the development of rot is therefore ever present. Ireland as noted having conditions suitable year round for interstitial condensation is likely to develop these problems earlier than countries with clearly defined seasons. These detrimental conditions however are not limited to Ireland, this is reflected in standard details for the control of such problems in countries including Canada, Finland, Sweden, Germany and of course Ireland. This is reflected in legislation related documents and published production details that are easily available.

The absence of proper building control over the past 20 years in Ireland (not exclusively) has resulted in there being many instances of the above conditions. For houses built up to 15 years ago with correct maintenance these are only now beginning to show signs of deterioration. Timber frame suppliers often provided the frames to contractors who completed buildings particularly in speculative developments without using suitably qualified professionals. The costs associated at the time with these professional services were seen by many to be unnecessary. The timber frame suppliers had at times been timber suppliers or saw mills who in cases I have seen developed systems again in the absence of suitably qualified professionals. Some of these systems were primarily supplied to one off projects, some were supplied to speculative developers. The absence of ventilation is possibly the most common of faults, inadequate protection of base or sole plates is another common fault. Another repeated fault is where ventilation has been blocked by owners or occupiers in the belief that the provided holes result in lost heat. This is due to an absence of instruction to end users when the building is complete. This in the form of a safety file is now common practice but has not been in the past, especially relating to one off housing. Heat loss is another common factor that disappoints end users who believed that timber frame houses are inherently better insulated. Using soft insulation as was very common some years ago in vertical spaces results in settlement and the appearance of insulation gaps or pockets within the structure, this further aggravates the possibilities of interstitial condensation especially where other factors are supportive of its incidence.

Conclusion.

Any assertion that the introduction of the BCMS process is adding extensive and unsustainable costs to the construction of smaller one off houses or extensions is in my opinion unwarranted. In fact, the process whether formalised legislatively or not should be applied to all buildings subject to building regulations. The absence of suitable control in the past has yielded expensive mistakes that could and should have been avoided. The bureaucracy associated is onerous, is in cases followed through by local authorities in the best interest of the end users, with inspections. The costs associated are of little consequence when associated with the services that should be provided. These costs are of no consequence when compared with the suffering caused by poor detailing, poor execution and the high cost of remedial work. Priory Hall is a highly public example of the absence of proper detailing and inspections by suitably qualified persons. While not being familiar with the full details, at the time this building was constructed it was common practice for developers to complete developments based on little more than planning drawings. These are not suitable for technical detailed work and would not be accepted under the current system. Nor should this scant level of detail ever have been accepted for any development. To accept less for a one off house or extension, (these often being amongst the largest financial undertakings by home owners) is negligent. To seek that control measures be removed from the process of smaller developments in the interest of fiscal savings is madness.

Other failings in the built environment relating to Radon gas, fire control and sewage treatment have been linked to deaths. The CIRI requires that it’s members be suitably experienced and informed in relation to detailing and construction. This requirement implies that other professionals be able rely on the contractors expertise. This does not alleviate the requirements of those professional responsibilities. The ever increasing specialisation means that expertise must be reliable.

Fifteen tests with fifteen possible results, or diagnoses. Anything other than what is anticipated and the system stops. There are two outcomes to the system stopping, one is that a new or revised system is adopted, the other is that it simply stops and there is no outcome. Which of the above relates to a project where the system is the purpose? Which relates to an outcome! Any project management system is nothing more than a tool to assist in achieving a desired outcome. Take an example of a health care system. The purpose is to promote health and healing. Where illness is apparent, the purpose is to find a cure. Fifteen tests with fifteen diagnoses. This relates obviously to a very simple and possibly standardized range of outcomes. The standardization of any system of this kind is clearly based on statistics. In carrying out tests for the conditions most likely it is possible to establish the illness quickly. If all fifteen tests yield no diagnosis, they will then proceed to the next system, a system other than the one normally practiced, a contingency or something entirely new. This then requires a combination of expertise, imagination, innovation, openness and intelligence. The patient is referred to a consultant expert. Common obstacles or supports to any system relate to belief. Not only a belief in the system, but a belief in the outcome,
and perhaps more particularly, that the outcome is possible. A belief that the fifteen tests have failed in arriving at a diagnosis is an obstacle or a limiting belief. A belief that the fifteen tests have eliminated possibilities is a success. A blind faith in the infallibility of a system leads at times to a false protection of refusing to be seen to fail. No one likes sharing failure, and if the belief is that the fifteen tests have failed then the sharing of results is at times refused. Where the belief is that these tests have successfully eliminated possibilities then the sharing of this information will prevent duplication. Duplication is the adding of unnecessary weight and uselessly expending energy. Duplication or any adding of tests that are not required costs time and money.

‘I have not failed, I’ve just found 10,000 ways that won’t work’. (Thomas Eddison)

Thomas Eddison of course references 10,000 different ways, and not of one way disproven 10,000 times.

Project management systems are the formalizing of thought processes. The emphasis being on thought where the formulas are mere tools. Should I travel back in time with a modern car, say to the middle ages, people would see the car operating without any apparent external power. Apart from the risk to me of being burnt as a witch, this simple demonstration would highlight to those a possibility. Assuming that no detailed inspection is allowed how long after this would a modern car become possible? It would simply happen because it is possible. However, while it may do everything a modern car can do, it may in terms of the system used be very different. This would be the result of expertise (that available at the time), imagination (considering with that expertise how something may be possible), innovation (invention), openness (unwilling to apportion the possibilities to witchcraft) and intelligence. All these factors must therefore be applied when an existing system does not deliver a genuine possibility. Thought is vital even when applying an established system. To blindly go where no one has gone before, is to apply an established system to a new challenge. It may work, but without thought it is not likely to. Essentially, it is never wise to ignore possibilities due to establishment practices. The fifteen tests noted are merely a representation of a system. All systems in order to have some level of success require rigidity. But! All systems in order to excel must be flexible. For simple or non complex goals, systems work. For complex goals, a series of systems may be required, though more importantly innovation and intelligence is needed.

Impediments and solutions to progress.

Science may be likened to religion, where adherence to a principal is dogmatic. The science of project management may therefore at times be a dogmatic adherence to a system or systems. The demonstration of achieving a goal that has proven impossible when dogmatically applying a system at times can generate a feeling of impotence in those applying the system. This is threatening, it threatens the ego as did anything unusual in medieval times threaten the status of established religion at the time. Fires burned. Fear is another major impediment to achieving goals. The fear of trying something new, the fear of being vilified for trying something new, the fear of being sued for trying something new, the fear of failure. If the fear of failure prevents one from trying….

‘Get rid of the fecking eejit barrier’. (Paul Ronan)

A patient visits a doctor. The doctor carries out a thorough examination with the limitations of equipment and general practice. While it is evident that there is something wrong, it is not possible with the GP system to establish a diagnosis. The doctor refers the patient to an expert and shares the FULL information gathered with that expert. (This it appears does not always happen). It’s like a relay race, the expert carries forward the gathered information in order to seek a diagnosis. This process continues, to other experts, to stations where highly technical scanners and equipment are used, the information gathered increases and the likelihood of a diagnosis. Any system or series of systems may be exhausted. This is not the failings of the individuals or experts within the system or the system itself. It is in fact the success of that system in eliminating possibilities. The remaining possibilities in each process are lessened, their number declines. Belief is a highly important aspect of achieving any goal.

‘Whether you think you can, or think you can’t, you’re probably right’. (Henry Ford)

What if that fifteen stage process could be reduced to five? Is this because the ten are superfluous to the desired outcome? Fifteen cogs in the machine, take for instance a construction project. In a construction project, there is a client, architect, engineer and contractor. There may also be services engineers, quantity surveyors, project managers and others. The need for each should be evaluated and anything superfluous should not be engaged with. Political interests, greed and the will to control are all aspects that lead to added cogs which will at best reduce the efficiency of the overall process. The primary interest must always be the end goal. At worst, the projects can be stopped completely. Evaluate the project based on complexity and size, reduce the number of cogs to the absolute minimum and then add only those that will make the process smoother.

“In our glorious fight for civil rights, we must guard against being fooled by false slogans, as ‘right to-work.’ It provides no ‘rights’ and no ‘works.’ Its purpose is to destroy labor unions and the freedom of collective bargaining… We demand this fraud be stopped.” (Martin Luther King Jr.)
The illusion of protecting the ‘right to work’ in instances where additional cogs are added for the mere purpose of providing ‘jobs’, whether for friends, family or the dispossessed is not the protection of any ‘rights’. It is in fact the neglecting of the ‘rights’ of the end users in any project. Any failure in the building of for instance a hospital due to adding needless cogs results in a delay in the treatment of illness and death for some of the end users. This is an almighty failure. A broken cog will fail in delivering the power to the end purpose, when broken cogs are realized the simplest and quickest solution is to remove them. This in no manner means that to employ is not correct, it merely states that in order to employ correctly, those employed must be supportive of the project. To qualify this further, to employ in this regard is to add cogs of any kind. Unfortunately, larger civic projects often have many cogs. These are added for a variety of reasons, much of which does not support the end goal. An example may be political interference in the proposed location of a hospital.

Ghosts in the machine.
Examples of weak cogs based on my own experience include invisible or concealed cogs. Inattention results in the expectation that others will perform and take in the slack, this is laziness. Ego is where individuals believe themselves capable of everything. I have encountered many examples of this and it relates to a pathological need to control and is more often carried out by those without ability than those with. There is at times a focus on the image as being the all important, the perception others have of the egotist. Those who have educated themselves sufficiently to carry out tasks often realize their inability to do everything. Greed blinds people to the greater good through the focus being so narrow. Lack of trust, again this relates to ego in that those who fail in trusting their appointed experts do so out of ignorance and a misguided self belief. All of these are invisible cogs in a machine and can sap the progress or energy completely. Even where the ultimate goal is achieved it is often less than is could have been.

Having unrealistic expectations relating to possibilities, costs or program are other examples of additional cogs that prevent growth or progress. These expectations often result in projects being re-evaluated, a time consuming and expensive process. It is a client’s responsibility to appoint expertise that they can rely on, that they trust. It is a following necessity that they listen to and pay attention to those experts. This is not only a progress related duty, it is in fact a legal responsibility relating in Ireland to building control and health and safety regulations. Additional measures are sometimes needed. Where the system and process is already successful, additional cogs should carefully be evaluated. This is a client’s responsibility based on the advice given by those appointed experts. Remember, these appointed experts are often well educated in their chosen specialist areas and are therefore likely to be familiar with their own limitations. It is of course the responsibility of the experts to admit their own limitations, both to themselves and to those they represent.

Procrastination can be a major impediment to progress in many respects. I will avoid the reference here to the failure in making decisions. In order to avoid procrastination be aware of the alternatives available where there is a possibility of a particular process not being successful. If you’re driving up a steep hill and the second gear cog shears, the faster you change to first in order to maintain progress the less likely you’ll come to a complete stop. If you procrastinate and fail in changing quickly enough the vehicle will come to a complete stop. Avoiding procrastination is about speed. Procrastination also relates in project management to attitudes, an experts opinion may at times be at variance with their clients. Where the client has been sufficiently informed an expert without very good reason should not insist on a particular technology. Insisting on something already decided on creates delays and additional costs. Make decisions quickly based on full information and progress. Avoid revisiting decisions already made.

Corruption generally increases the costs of a project both in terms of time and money. At its most basic form, corruption can arise by placing the wants of an individual above those of a collective. This can be done subconsciously where the need for simplicity is seen as taking the first option when it may be true that another option would serve the project better. By definition it relates to the corrupting of a project. This can be as simple as arguing about a technology or adding an additional unnecessary cog. Corruption may of course be deliberate, that’s for another time.
Conclusion.

A client’s responsibility to appoint suitably qualified and able people to carry out tasks needs to be accompanied by trust. Is it the responsibility of a client to double check their agents ability, or can they merely base it on trust? This is the reason for organizations and legislation attesting to individual’s ability, it may well be considered the clients responsibility to check suitable registers.

The agents or experts responsibility is to their clients and the processes needed to achieve a desired outcome. There is a strong emphasis on the honesty of making claims to actual abilities.

Focus and attention of all involved is of paramount importance in achieving anything. The more complex the intention, the more flexible the process must be.

Who owns the project? Who manages the initial control of a project?
It is the initiator of the project who carries the responsibility. It is also often the initiator who requires most the abilities of those experts appointed in order to comply with that responsibility.

Recently, a colleague informed me of his difficulties in procuring viable projects. He had in the past two years completed a modest extension which included alterations to a semi-detached house. His clients had established a budget without consulting a professional and had established what was ‘possible’. I can only surmise that the evidence on which this budget was based was pub conversation and word of mouth. In reality it appeared highly unrealistic. Their budget was very low and their expectations very high. My expert colleague managed their expectations very well, to a point. For the tender stage the clients selected a contractor who was included and it transpired that his tender was the most economical. The margin was of concern to my colleague and he expressed this to the client. As protocol dictates, he asked the contractor if he would stand over his tender. The contractor duly complied, even after it had been suggested that the margin was extensive. A contract was entered into during the course of which it become increasingly evident that the contractor was struggling to complete the works within his tender. In fact, my colleague estimated the project to have cost the contractor. The clients in their wisdom had removed certain aspects from the contract in an attempt to affect savings. The kitchen was supplied and fitted by the client, the flooring, decoration, site completions, tiling, and other small items were all removed from the contract, thus having a more detrimental effect on the contractor. My colleague believes that the contractor has since emigrated.

This is a typical scenario. But also typical is a reluctance of people to admit their actual expenditure. A more interesting aspect to this story is the client’s subsequent claims to their friends (probably in the pub) that the costs of the project were low. In fact, the costs that they claimed were lower than the contract sum, though they claimed to have completed all the works, including the kitchen, the flooring, decoration, site completions, tiling, and other small items, below the actual contract sum. This was a blatant attempt to appear to have spent less money, possibly with the intention of highlighting that they didn’t have money to spend. Whatever the reason, the effect is that they managed the expectations of others, who then, like they had, established what was ‘possible’.

This reality has a more sinister effect. For it may be possible to have works carried out for the low costs noted. I personally have witness over the years of providing a professional service evidence of these savings. I’ll restate that it is possible to have works carried out for the low costs rumoured, this is due to the effects of pressure for that ‘possible’ and for the willingness of certain ‘handy men’ to exploit these rumours. Mild things like spiders being painted over, painting with no preparation are common. Less obvious are works relating to foundations, floor structure, plumbing and electrical installations. I inspected a house where there had been added electrical sockets in a kitchen, linked to the cooker feed. Should appliances fail, or the sockets themselves become faulty (one was located beside the kitchen sink) the circuit to which they were connected was rated as 32 amps, far higher than the required cut off for the sockets. This could have resulted in fire. I have also seen live wires, still connected and thrown above ceilings to be forgotten, a serious fire hazard in an area filled with kindling. Boilers with no ventilation, unsealed gas units, cheap and rotten chipboard floors on undersized joists, replaced pipes covered, not having been replaced at all.

Who of us would have a general handyman fit new brakes to our cars, in the mere interest of saving money, or saving face. ‘Look I got these brakes fitted for nothing!’. Just before driving into a river. Who of us would even consider this, yet each day people take risks paying people less. When I go to a doctor, I expect a doctor. For my car I expect a mechanic. For my house I would do nothing to risk life, we spend so much of our time at home, we rely on the carbon efficiency of our heating devices, the reliability of our electrics and the comfort of our home.

The only way to manage the expectations of anyone is to tell the truth. It is better not to begin something than to begin ill prepared. I wouldn’t begin a long journey across a desert with half the fuel that I needed.

http://www.progressio.ie/water/water-in-ireland/

150 litres per person equals about 600 litres for a household of four persons, or about 220,000 litres each year. Ok, that’s average! What can we do? As architects we can ensure that new developments or renovations use taps and toilets that use less, that we harvest any water that we can for re-use in gardening or external washing and for the flushing of toilets. If the average efficient toilet flush uses 8 litres, and we each flush the toilet about 5 times a day, that’s 40 litres if the toilet is modern and efficient. For four people that’s nearly 60,000 litres each year. All the other uses, washing ourselves, clothes and dishes, washing the car, the patio, the windows and the dog use water too! If we washed the patio, the car, watered the garden and flushed the toilet with recycled or harvested water we could significantly reduce our net water consumption. Dishwashers use about half the water that is used by washing dishes by hand. Where renewable energy from sustainable sources is used, then using a dishwasher is more environmentally viable. In essence we could easily half our consumption with little change to our life style. Add to this the question, is our life style sustainable? Perhaps we should examine our life styles in order to ascertain whether savings could be made with small alterations.

Water charges are proposed in Ireland and are roughly based on the average adult use. The proposed domestic allowance is slightly in excess of this. It is not clear as yet whether the allowance will be the amount of water that is proposed to be used within the standing charge. As the standing charge is however cited as being for the provision of water metering services and maintenance of the system it appears that the standing charge may not include any amount of water. This is reflected in the low annual standing charge of €240. It has been reported that the annual real costs could average €560 per household. Whether this cost is passed on to customers directly or through other ‘taxes’ has no bearing on it being a real cost. Removing the standing charge results in a cost per litre of 0.15 of one cent.

http://www.irishtimes.com/business/sectors/retail-and-services/one-way-or-another-you-will-pay-for-running-irish-water-1.1791345

If we reduce our consumption by half at home we can theoretically reduce the cost by about one third, or €165 per annum. Do we need more incentive? Yes! Using more water away from home is definitely going to cost us more, added to which any unnatural increase in water use away from home is likely to yield an increase in general services costs. The gym will get more expensive.

However, the imagined incentive is to use less water rather than alter our lives to be more efficient. This may well lead to some of us neglecting the more important things in life, like drinking water and being clean. The real rewards should perhaps be applied to those who implement measures to save water such as using low capacity toilet cisterns, low use taps, rain water and waste water harvesting. A possible incentive is to have a low standing charge that includes the use of an efficient water use relative to the size of house. This would make it possible for people to live with the standing charge. In large cities the treatment of waste water for human use is common with their often being no other option. The concern is not the final quality, treatment in the developed world for this waste water is excellent. The concern is the cost and the need to improve the capacity to produce high quality water. Overtaxing these systems with surface water or wasted fresh water incurs greater cost. Efficient separation of drainage systems needs then to be established everywhere and enforced. There is little effect in proposing that all new development have separate drainage systems without implementing these systems in the public areas. There remain large areas predominantly of high density where separate systems do not exist other than in private developments. This separation is then cancelled once in the public domain thereby taxing the treatment systems unnecessarily.

Why save water? In Ireland in rains, there is plenty of water! The truth is that this water is not treated and not fit for human consumption. Of more concern is the depletion of the aquifers in Ireland. Despite the apparent increase in rainfall, the aquifers in Ireland and throughout Europe and the developed world are in danger of continuing to deplete. The very essence of our land is drying out, withering below us. This is invisible and difficulty to imagine when floods increase. The consequences of our continuing disregard includes in the short term ever rising services costs, but in the long term may be far more serious. These aquifers are our source of naturally treated water, filtered through ground systems over many years. The water cycle relies on natural surface water permeating back to the aquifers below. Prior to treatment, waste water has high levels of various toxins, chemicals from washing, detergents, oils and so on. These may well contaminate future aquifers. This is an important reason why foul drains should never mix with surface water drains. Add this contamination to low levels in aquifers and the proportionate contamination is higher.

In the developed world we can easily reduce our water use by as much as 75%, this would based on the current proposal in Ireland yield a saving in financial terms only of approximately 44%. A lot of effort for apparently little return! The world despite the impression that we are given is only in small part financial. It would be fair to reflect the truth and afford a consequential and equitable reward in terms of finance to those practicing restraint. Were the cost of this restraint alone credited to those diligent more will be achieved. Revenue is needed to repair and upgrade the public systems. Increasing the capacity of the treatment systems to cater to the actual demand (including surface water) without trying to reduce that demand does incur additional costs. The solution requires the cooperation of the people and the authorities in their combined attempts to address the problem. We should cooperate both with use constraints and effluent control. Our future is important!

Attached is a temperature chart relating to a low energy house, the front of the property is North facing, therefore subject to lower temperatures. Temperatures in this building were recorded over a period of two years and the attached is a sample dating from 1st March 2011 to 3rd March 2011. It highlights the possible variations in temperature that are typical in Ireland with a low external temperature related to the high external temperature variation of over 20 degrees in a very short time scale. This also highlights the particular difficulties faced with low energy buildings in Ireland, emphasized internally where the temperatures were not automatically controlled. A quickly varying environment generates conditions that require constant internal monitoring and control in order to facilitate comfortable living conditions. At times the relative humidity internally in this house became uncomfortable. Throughout the period of this study, solar gain featured predominantly. In the total two year period there was no period of more than three days where solar gain did not provide valuable heat. Other than appliances there is no heat source in this building. This highlights the need for temperature control in low energy buildings through automatically monitored and controlled ventilation. The energy requirements for this automatic ventilation have ben calculated as being in the order of 900 kW/h per annum for a 260 sq.m. house for the space heating / controlling energy demand. This equates with less than 4 kW/h per square metre per annum. This cost relates to the energy requirements of the Heat Recovery Ventilation system. For comparison, Irelands BER (Building Energy Rating) for an A1 rated house (the highest rating) of less than 25 kW/h/sq.m,/annum. Other energy use within the building is included in this BER rating, lights, appliances, hot water, etc. The average electric use in houses in Ireland per annum is about 6,000 kW/h. To apply the average use, the total BER rating of this house based on performance would be in the order of 5591 kW/h/a or have a BER rating of A1. However, the average energy use per occupant assumes that this is based on there being three, which is correct for this house. The passive house standard is 15 kW/h/sq.m,/annum. This may be achieved with the use of low energy units, ‘A’ rated appliances, etc. These have been implemented in this particular house and the standard has been achieved. However the average use of electricity per person has increased over the years. For instance and as a guide to possible future developments in Ireland the average electricity use per person in the USA is more that twice that for those in Ireland. Were Ireland to follow the USA in this regard the passive standard would become impossible without having an ecological and efficient means of production within each development. These could include Photovoltaic solar panels, hydro generators in streams or small windmills. Perhaps the best solution is for each of us to review our energy use.

Kanuri

Low energy or passive buildings require high levels of insulation and air tightness. Imagine wearing a knitted woollen jumper on a cold windy mountain. The wind will penetrate the jumper which will be of little effect. Add a wind proof though light layer and the effects will be highly improved. Air tightness is of high importance. The cost of applying these improved systems to new buildings is reducing due to increasing demand. There are also more options on how this effect can be achieved.

Other elements of sustainable architecture include the source of materials, that they are both suitable and easily obtainable. Transport and manufacture costs should be included in any analyses as part of the energy design process.

Viking

In sum, low energy use can be achieved. The passive standard while achievable is subject to corruption with ever changing requirements in energy use. The best that we can do is the constantly seek to be the best that we can be.

In order to understand the detailed nature of project management and therefore possible shortcomings of any particular system it is perhaps prudent to outline in brief the skills needed. These are either inherent to individuals or applied through the use of systems. Projects are by their nature temporary with specified goals or outcomes. The construction of buildings involves project management from inception through to the completion. After completion operation management takes over. Operations management is the day to day management of systems where repeatable actions are required. Unlike operations management, project management requires an understanding of the other. An example is the design of a car, it would not be possible without knowing how it is commonly used.

Ideally, where buildings are concerned, a visualization aptitude is advantageous. The ability to visualize spaces and hidden services in three dimensions with understanding of both micro and macro requirements is vital. This can be done using tools such as BIM though is limited as the input required may be extensive and highly detailed. This requires a detailed knowledge and understanding of those systems. This limitation impacts where changes are made to any of the elements and where detailed analysis is required in order to evaluate the effects. The innate aptitude that some individuals possess and on which BIM is based means that these detail changes are understood in an overall context without delay rendering the process highly efficient. This impacts where fast and concise decisions are needed in order that projects are not delayed. Delays are expensive! On any project it is required that the project manager, be they architects, engineers, master craftsmen or project managers be highly familiar with every detail of a project that may impact on the final success of that project. This includes the physical, the contractual, the legal, the administrative and practical application of all that is required. This comes from aptitude, experience and training and may be supported by tools such as BIM and the Gantt chart. Examples of BIM images require an understanding of the elements being portrayed without which vital elements may be overlooked. These omissions can cause additional costs and delays and may in some cases result in abortive works.

It is therefore vital that project managers understand the building processes, the project particulars relating to all aspects and the people involved such that success is probable. It is difficult to overstate this requirement! The best project managers are those who have a detailed knowledge of the industry in which they manage and possess the required aptitude. Training and experience serve to support an innate aptitude as do the tools.

The onus on clients or building owners to appoint competent and qualified persons as certifiers includes both designers and contractors. This applies to any building for which planning permission or material alterations to commercial buildings are concerned. Material alterations include any changes that have an impact on planning regulations or building regulations. All previous Building Control Regulations apply in this regard together with the currently implemented amendments. The ‘Planning and Development Act 2000’ Number 30 of 2000 together with any accessibility regulations may also apply. Accessibility regulations relate to any public or commercial building to which the public have access, where in any new development or alterations to existing building a ‘Disability Access Certificate (DAC) may be required under regulations that came into effect on 1st January 2010. A ‘Fire Safety Certificate’ may also be required where alterations are carried out or proposed to be carried out.

The purpose of these improved regulations is to bring more control on the building industry arising out of concerns with standards over the past ten or so years. Developments such as ‘Priory Hall’ have been cited in the development of these amended regulations. The onus has however been placed on building owners and managers to implement these measures. Local Authorities are required to evaluate and keep on record details that demonstrate the buildings when designed will comply and when completed have complied. These are in the form of prescribed forms which will be attached to detailed design documentation, specifications and calculations. In the event that a development appears to fail to comply with these regulations it will be possible with relation to these documents and certificates to establish the breach. Failure to comply may be considered an offence.

The manner in which standards will be improved will be to ensure that the designers are suitably qualified and capable of certifying both the designs and the works. These qualified certifiers will rely on other consultants in certifying the design. In addition to these they will also rely on suitably experienced contractors, though as yet there is no legal definition of building contractors. There is a requirement that design certifiers be suitably qualified and registered. There is no legal requirement that building contractors be suitable qualified nor is there a legally defined register. This is being addressed and is likely to become required in the coming year or so, we are informed. On this basis and with foresight it is wise to seek that any contractors carrying out works be registered with the CIF through their CIRI registration body.

Works that are subject to planning regulations include material alterations to existing commercial buildings, alterations to domestic buildings that require planning permission are defined in the Planning and Development Regulations 2001. Any alterations to protected structures or to elements within the cartilage of a protected structure may also be subject to this act. In certain conservation areas, additional measures are imposed by local authorities. These often relate to archaeological requirements where ground works are proposed.

In order to facilitate better development and therefore improved conditions in the built environment the requirements of these acts have become the responsibility of anyone proposing development of any kind.

Additional to the above regulations, the ‘Safety, Health and Welfare at Work Act 2005, No. 10 of 2005’ and in particular the ‘Safety, Health and Welfare at Work (Construction) (Amendment) (No. 2) Regulations 2012, S.I. No. 481 of 2012’ should be addressed fully. This relates to all parties but initially to the responsibility of owners and building managers who are considering have works carried out.

The complexity of legislation relating to property is such that advice should be sought of suitable qualified and experienced professionals prior to initiating any development. Project management includes all of the above together with the complexity and variation in services required to have any project correctly implemented. The building industry has become a highly detailed and skilled industry where knowledge of the wide range of services and skills is needed by managers in order to facilitate the transition from concept to completion.

The above is not an exhaustive list of the requirements needed but is a base outlining the needs for expertise or for the requirement to appoint expertise when carrying our development.

Architecture is the art and science of designing buildings and other physical structures. It is both an art and a science and is therefore open to interpretation from both a factual and emotional perspective. To me it is personal.

It is my task to provide spaces to my clients’ requirements. The effect that these spaces have on the environment, both internal and external and consequently on all people who experience them is my responsibility. This includes both the emotional and scientific effects. In order to provide this service effectively I must have a deep understanding of both these aspects. I must be able to listen and respond to the emotional expectations of my clients while attending to the scientific or technical aspects of my profession also.

Today I will focus on the scientific aspects that are of concern to me as an architect, and should I believe be of concern to every architect.

The environment.

In relation to architecture, this is an extensive area, it covers both micro and macro environments. It includes the smallest visible condition of buildings, are there enough screw fixings in each of the door hinges to the press? It also covers the chemical reaction that causes rust, and knowledge of the catalysts that make steel more prone to this reaction. This is a molecular concern.

The largest effects are also of concern. How do Sun spots affect the earth? What causes global warming and what if anything can we do to control it? These are also of great importance in designing buildings.

Architects are increasingly designing buildings to conserve energy in all its forms.

Energy.

Both the conservation and production of energy have been the major focus of the world’s governments for the past ten years. I have spent a good portion of my free time over the past 30 years studying both these aspects of energy. With this I have had a philosophical focus and through this have expanded this to the development of an energy efficient transfer machine which will I hope be used in the production of energy. Through a detailed understanding of energy conservation I have also started developing technical design details particularly suitable for the Irish climate.

Energy consumption.

We all in the West consume vast amounts of energy, through the burning of fossil fuels and bio fuels. There is no doubt that this produces pollution. This has long been understood to cause environmental problems, from the pea soup fogs in early industrialised cities to the insidious Ozone fog of more recent metropolis. Part of the service that I provide is to audit energy usage and to provide advice on how this can be improved. The current popular label for the levels of pollution that we cause is the ‘Carbon footprint’. The international control of this is both costing and making billions of Euro. Carbon credits are being traded.

What is the current level of Carbon in Earths atmosphere?

380 parts per million (ppm). CO is a greenhouse gas. What does this mean and what are the implications?

The implications are that were there excessive amounts of this gas in the atmosphere, the world would retain its heat. What would be excessive?

We have had in this world a number of Ice Ages, the last major ice age ended about 10,000 years ago. The levels of CO in the atmosphere at that time was 190 ppm. The highest levels of CO in the atmosphere during an ice age have been stated as being 3,500 ppm.

Global warming.

The relationship of CO in the atmosphere with global warming has not been consistent, implying that there is another force at work in global warming. Sun spots have been cited as having a stronger relationship to global warming. In any event, it is not clear that CO is responsible for global warming. There are far more potent greenhouse gases in the atmosphere. Methane is one which has also been cited in popular culture in recent times. Popular culture is driven primarily by the media, and not by science. Farting vegetarians produce Methane, by vegetarians’ I mean herbivores, cows, sheep, etc. Perhaps the most effective of greenhouse compounds is water. Consider a summer day with clear blue skies, it’s warm. Consider a summer night with clear skies, it’s cool. Consider a summer day, overcast, cooler than warm and the overcast night is warmer than cool. Greenhouse compounds both reflect and trap heat.

380 ppm is an annual estimate, of which we are attributed as being responsible for 3% or less than 12 ppm. Were this content to increase by our contribution each year it would take 260 years to reach the levels of 3,500. It is however, not accumulative as CO is processed in a number of ways, perhaps the most notable being the photosynthesis of plants. Plants change CO into chlorophyll (food) and as waste produce Oxygen. It is true that the world has in recent times become warmer, one estimate states a fraction of one degree. The world it should be stated has also recently cooled.

Effects of global warming.

There died some 14,000 people in France in 2003. Popular culture (the media) reported this as being an example of global warming, the doom to which we would all possibly secumb should we fail in our duty to act. Also reported at the time was that plants in Paris ceased photosynthesizing, it being implied that this was the result of the excessive heat. The idea that heat could cause this was alarming.

Does heat prevent photosynthesis?

Simple answer, no. Actually NO is a very good answer. We have been told to curtail the use of fossil fuels to prevent the production of CO. While the reasoning for this may be suspect, the effects are possibly good. In burning fossil fuels we also produce other chemicals, one being Nitrous Oxides or NO. The presence of NO in the atmosphere can when heated react with Oxygen to produce Ozone. The excessive presence of Ozone at or near ground level is a polutant that prevents the photosynthesis of plants. Other chemicals that are by-products of our way of life are Volatile Organic Compounds (VOC). These are the product of household cleaners, aerosols, detergents, pesticides and the like. These also react in the environment to produce Ozone. With no NO, and no VOC in the atmosphere, heat increases the photosynthesis of plants. Heat is good for producing Oxygen.

Therefore, polution is bad.

What can we do?

We should plant more trees, and in order for these to be more effective we should produce less VOC and less NO, which means less CO too. We need to focus on the possibiliteis of technology in order to produce more food while using less resources. Alternative energies need to be developed. Education. There are 6.5 billion people in the world, of which less than one billion live in the developed West. We benefit from technology like no other society, ever on earth. We produce more polution per capita than any other and use more resources. We have the education and resources to develop technologies that will reduce our impact. We suffer from limiting beliefs. The belief that we are correct shuts the door on other possibilities and may serve to prevent progress. This is a world problem and needs the collective minds and extensive varying cultures and viewpoints to solve the problems that we have.

How can I help?

As an architect I can design buildings to suit the needs of my clients, with emphasis also on the needs of those people who will be affected by the impact of my designs. In order to limit the negative effects energy conservation is all important. Energy production and the harnessing of passive energies with simple considerations like the orientation of buildings to capture the Suns energy. I study the possibilities, what is being developed and what might suit each need the best. This is one aspect of architecture. Architecture as a science.
