With the Grenelle de l’environnement still in the air, the bioclimatic home is all the trend. Explanation…
Basic principles
Thanks to a well planned architecture integrating the environment and climate, the bioclimatic home is extremely energy efficient. Use of appropriate materials and room orientation makes it possible to maintain comfortable temperatures and take advantage of lots of natural light. Heat is collected in winter, stored, then distributed throughout the house.
Design
The bioclimatic house has very few northern, eastern, and western-facing openings, but significant glazed surfaces to the south.
The rooms to the north are reserved for what are called buffer areas: garage, cellar, utility room, etc. They serve as thermal insulation and reduce heat loss.
The main room faces south and features large picture windows. Heat is consequently collected during the day. Shutters or blinds provide protection at night and prevent overheating in the summer. A roof overhang or deciduous plants are also frequently used.
Thermal study
The bioclimatic house is designed to limit heat loss. Compact in shape, it faces south and is protected from the wind by plantations that shelter it from the wind. Wall structures are mainly made of wood, monowall brick, pisé, or stone. The house is insulated (links to green insulation) using materials that breathe (flax, hemp, unvarnished wood, etc.) and provide better comfort.
