Comparative study of the efficiency of earth/air heat-exchangers versus direct solar floors systems for residential buildings in Belgium

peer reviewed ; Net-zero-energy building concept is a solution for high-performance buildings that integrates passive design and energy efficiency measures with renewable energy systems. Given the specific technical characteristics of net-zero energy buildings, two technological solutions are investigated, in this experimental study: Earth/Air Heat-Exchangers and Direct Solar Floors. To carry out this study, an experimental cell composed of two rooms equipped with two energy systems was constructed. One room is coupled to a solar thermal collector with a surface area of 4.60 m2 and the second... Mehr ...
