Abstract:
At high densities, populations must employ strategies of efficiency to survive. Human beings are unique in the history of the world because of the sheer scale of the impacts we have had on the global environment and in particular on the Earth’s atmosphere, and our ability to comprehend,and alter, them. Buildings are only part of our habitat. Buildings are intimately linked to the local, regional and global environments that are all part of our ‘Ecological Niche’. It is the responsibility of our generation to begin to adapt our buildings to ensure that we can stabilise climate change, that we can live without fossil fuels and that we do not unsustainably pollute the environment. Only by so doing can we ensure the survival of our own habitats. Traditional buildings have much to teach us about how to design regionally appropriate structures. We can change fast enough. We can mix the wisdom of the master builders,new knowledge, materials and renewable technologies to create ecobuildings, the New Vernacular, to minimise the environmental impacts of buildings. We can now measure those impacts with the new methodologies for counting the environmental costs of buildings. We do need a new type of designer, part architect, part engineer, and to get rid of heating and cooling machines where possible or power them with renewable energy.Buildings are our third skin. To survive we need shelter from the elements using three skins. The first is provided by our own skin, the second by a layer of clothes and the third is the building.That’s why the people try to adapt the shape of their buildings to the climate features: see the yurt, the igloo, the swallow, the bucket and periscope shape houses.The temptation to ‘innovate’ can often lead us unwittingly into problems, but from them we learn. For example, the early solar houses often overheated because, in the rush to utilise free, clean solar energy, the dangers of the sun were underestimated. The best modern buildings do have excellent solar control and yet it is astounding to see how many still employ glass roofs and walls that not only can cause severe discomfort to people inside but also can result in huge bills for compensatory cooling systems.A ground source heat pump is an extremely effective device for reducing the carbon emissions from a building’s heating system in most circumstances. In one of this device, underground pipes are used to harvest the sun’s warmth, which has been captured and stored in the earth, and move it into a building. Where the conditions are suitable heat pumps can capture enough solar energy to provide all of the water and space heating requirements of a small or large house, and in some projects they can do the same for massive offices and retail stores. Small system wind systems and hydropower are also very fine solution for modern, passive and friendly houses.
