The building has to be designed to last and its function is to create comfort. It should also be made not to waste energy, but to recuperate and regenerate it. An ecological building is a quality building, created with long-lasting materials which reduce maintenance costs. Depending on the context and possibilities, the main objectives are to create harmony between the building itself and the place where it stands, to save energy and to guarantee the health of its inhabitants. Eco-architecture guidelines These may be taken as guidelines: mainly utilize materials available in large quantities , unrefined, (to reduce energy ), and which do not harm human health; in loco which need little manufacturing waste guarantee the buildings flexibility for the possible future changes; try to design an efficient (thermal isolation, natural lighting, etc.) by using innovative technological devices; energy saving system guarantee the of the construction; durability use once the building is demolished; materials which can be recycled and re-used provide the structures with (sufficient lighting, natural colours, etc.). natural beauty and “sensual” comfort WARM UP What is eco-architecture?
