    • The first undeniable advantage of this house is the reduction of expenses. A reduction of nearly 90% in the amount of heating costs can represent significant sums for households. To build in liabilities is also to guarantee oneself of all energy poverty.
    • Certainly build in liabilities requires more in-depth design work and rigorous site monitoring. If winter comfort in passive house is no longer in doubt, summer comfort remains a subject to be deepened. The Passivhaus labeling criteria impose an overheating frequency of only 10% of the time above 25 ° C. But the examples of passive certified buildings in the world and especially in hot countries like Dubai or Morocco (embassy of Belgium in Rabat for example) are more and more numerous and show that it is possible (See tertiary passive buildings and New ecological architectures published by Editions du Moniteur).
    • To meet the constraints of passive construction, the designer of this house has used the benefits that the land could bring him, then he optimized the set by implementing building elements derived from the rules of bioclimatism and Passivhaus, such as compactness, orientation, shutters-louvers positioned outside, the use of concrete in strategic locations, the installation of a reflective film on the roof, the waterproofing air reaching in n50: 0.21 v / h, a design without thermal bridge, an insulation by the outside, a VMC double flux with 93% of recovery of heat etc ... All this made it possible to reach exceptional performances.
    • At first glance, this house looks like neighboring Provencal houses. Yet in this ordinary appearance hides a jewel in terms of comfort and performance, with a need for reduced heating to 1 kWh / (m².an) and a primary energy requirement of 54 kWh / m².an for heating, l hot water, lighting, ventilation and auxiliaries (according to the PHPP software essential to Passivhaus certification and recognized as reliable by all experts, unlike the calculation engine of the French thermal regulation, the TH- ECB).
    • In addition, thanks to 42 m² of photovoltaic panels and 4 m² of solar thermal panels, this house produces 4 times more energy than it consumes all uses (including the load of the hybrid car). This is a particularly interesting advantage in a region with a large deficit in electricity supply.
    • In addition, French thermal regulations will impose the Bepos (positive energy building) on ​​all buildings in 2020. When energy needs are low, some photovoltaic panels are enough to become Bepos (positive energy building). The saving made on photovoltaic panels makes sense and compensates for the additional cost of passive construction.
