The starting point of all sustainability is climate-oriented building design. The sun is the most basic natural resource in the whole world. Then comes, for instance, wind, water, geothermal energy, and ambient air. In a building’s design, these sources must be taken advantage of through orientation, fenestration, precise handling of solar exposure, for gain or prevention of heat and light, natural ventilation, and the use of wind forces, sufficient storage mass, and smart building skins. Today, the design options and strategies available for utilizing natural resources in the design of a building are still far from being fully exploited. The energy consumption of a building depends on need, which in turn depends on the design of the building. That’s why the degree to which a design is developed in symbiosis with the energy strategy is of vital importance in terms of cost. In a sustainable design draft, natural strategies – the employment of natural options – are always explored first so that the supplemental technologies required can be kept to a minimum and the construction is done as cost-efficiently as possible.
If the design and the construction standard are adapted to the particular climate in question, then all prerequisites are in place for creating the most comfortable interior climate conditions with cost-efficient, intelligent building systems.
