Are you concerned with sustainable development? Would you like to live in a comfortable ecological home but you do not know how to proceed. Here are some tips to do so. In order to get an ecological house, you have to reduce the impacts on human health and the environment, make it energy efficient and reduce water consumption. Materials are the primary point to look at. Building materials should be non toxic, naturally regulating air moisture, renewable and locally available to avoid transportation cost. Among them, stones, bricks, wood, straw are typically considered to be green materials for construction. Thermal insulation is a key in order to minimize energy losses (roof, walls, vent air, windows, floors, thermal bridges). Unless you already have a passive house (zero energy) your heating system has to be eco friendly. Today renewable energies are booming: solar (thermal and photovoltaic), wind, biomass, heat-pumps (geothermal, air). New equipments are more and more available with prices going down and many states offer financial incentives.
