Abstract : « Positive Energy Buildings » are a concept of high-performance buildings considered to be one of the possible solutions to nowadays energy and environmental challenges. Nevertheless, it is still not widely known and hardly implemented. In the light of some existing buildings, this concept has been defined and characterized. Next, several tools and methods have been identified in order to carry out analyses on the building performance. Considering the technical specificities of positive energy buildings, two technological solutions have been studied more particularly: a ventilation system including an earth-to-air heat exchanger has been modeled and validated from measured data; a micro-CHP air heating system has been modeled from data coming from a specific test bench. These two models have been integrated into a building thermal simulation tool. An energy and environmental analysis has been carried out for three existing high-performance buildings equipped with various heating systems, using the improved tool and the most adapted methods. The heating system as well as the evaluation criteria strongly influences the results. A positive energy building (primary energy assessment) is the best performing solution for the majority of the studied environmental impacts. A life cycle assessment and a cumulative energy demand calculation are means of characterizing its environmental performance in detail.
