Much of the sustainable architecture is therefore based on the control of the energy consumption of a building:
reduction of energy losses through the installation of effective thermal insulation, in particular through the judicious use of materials
minimization of energy needs, in particular through the orientation of the building according to its exposure to the sun and the location of the site
collection of natural energies, for example with the installation of natural ventilation and cooling systems
production of alternative energies such as solar or wind power to reduce external energy inputs and, if possible, create energy-positive buildings
Reduction of wastes
Another important part of sustainable architecture is the minimization of pollution and the generation of waste. This can be implemented by the recovery of rainwater, in particular for plant watering and recycling of wastewater, integration of waste sorting systems and composting of organic matter. Using non-polluting materials can also be a means of reducing the emission of volatile organic compounds.
