The thermal approach, at the base, consists of limiting the energy consumption of heating, air conditioning, ventilation systems, etc., in new buildings or to renovate.
In general to reduce the needs of a building we will act mainly on its thermal envelope, but not that we will try to build or modify this building using the principle of bio-climatism, that is to promote the radiation solar in winter, while reducing it in summer, limit or remove openings to the north for example, and many other things.
But all this would be useless if we forgot the fundamental principle of generating comfort in all seasons for the occupants and users of the site, ensure correct temperatures but also and above all an optimized moisture is essential, that's why that in addition to acting on the building envelope by judiciously choosing the appropriate building materials and insulation, one must also master his breathability and the transfer of water vapor through the walls .
When all these concepts are well taken into account in the study of a building, we can easily consider that it will be low energy and very comfortable to live.
For the occupants the results are immediate and very easily visible, the heating or other bills are low or even very low, but above all the quality of life and the healthiness of the premises are without equal, to this if we add the use of ecological materials thus guaranteeing users a healthy life in an environment where the quality of the air will be irreproachable.
