Eco-friendly house that traps sunlight to heat the rooms at night
Nicolas Dorval-Bory and Emilio Marin have thought of an interesting dreamhouse for a ski-enthusiast. The speciality of this home is that it is made of ‘aerated concrete’. Though these blocks look like regular concrete, they are in fact filled with tiny air bubbles that perform some green functions. Firstly they reduce the shipping weight as well as increase the insulating properties. The green quotient of the construction has just taken off. A geothermal heat pump is used to pump air into a trombe wallthat trap the air in them. Since the wall is exposed to the sun, they warm the air. This warm is is inturn circulated inside the house at night. Not only this, the house is constructed in such a way that bedrooms and bathrooms lie at the house’s south end, where they’re exposed to the sun but buried partially in the ground, so those areas are naturally warmer.
