LIGHTING that some luxury design items may have to There is a maximum energy consumption be sacrificed in order to comply. It is all about allowance for lighting in buildings. In a typical changing the mindset of the public in general house the allowance is an energy demand of 5 and the client in particular, and embracing the watts/m2 (basically if all the lights are switched new legislation as a valuable resource. And on at the same time) and an annual energy although there may be additional costs upfront consumption of 5 kWh/m2 (the annual energy in the building process, energy efficiencies will usage based on the average hours per day the recover those costs over time. lights would be switched on if they were all on at the same time). The new regulations have also slightly increased production time and the workload, architectural In simple terms, the old incandescent and professional’s as detailed halogen bulbs that we are used to are no longer calculations have to be made of hot-water viable due to their high energy consumption. consumption, building orientation, window LED and CFL bulbs are the only types that efficiency and lighting energy consumption. comply with the requirements. This requires more detailed drawings at the council submission stage of the project. CHALLENGES TO ARCHITECTS Many contractors and subcontractors are not Implementing the new regulations was a as familiar with the building regulations as they steep learning curve for most architectural should be. It can be challenging to tell them professionals. The mindset had to move very that the way they have been building is wrong, rapidly from decades-old accepted inefficient and to persuade them to follow the drawings building practices to a new awareness of and specifications explicitly. For example, the minimum standards required by the very few plumbers know how to install a hot- amended legislation. Although challenging water system with a ring main system. Even at the time, this has also proved beneficial, though these regulations have been around because it has forced many professionals to for decades, they have never been properly be more conscious of what they are designing. enforced by the local authorities, so many So, rather than designing something just to installations have been done incorrectly and look “nice”, one is now forced to implement inefficiently. This means that while many are functional design principles that have been willing to try to comply, the new regulations do around since the dawn of architecture, when increase the possibility of errors. I was recently buildings were designed to be functional in a house where the water from the hot tap elements in harmony with their environment, would run hot for about five seconds and then rather than just objects of beauty or status go col d – because the hot-water system was symbols. not going through the geyser and was feeding direct from the cold water supply, syphoning Architects often have to educate their clients, off a little hot water along the way. most of whom are not familiar with the regulations. It can be difficult to explain to a Ultimately, the responsibility of enforcing client that the regulations require certain non- the regulations lies with the architectural aesthetic but costly building solutions, and professional.
