The Passive solar

  •  The Passive Solar :

      The passive solar energy is the recovery of energy sent by the sun to produce heat for free and without impact on the environment. it works according to the principle of the greenhouse effect by using windows to produce heat. The energy produced is stored in the floor and walls for efficient redistribution at home The energy contribution is about ​​​​​​​35% in the south-east / south-west exposure and can reach 70% in December in the case ​​​​​​​of a southern exposure, it is not​​​​​​​ negligible.
