The eco-district “Les Vergers”, located in Meyrin (Geneva, Switzerland), hosts around 1'350 dwellings and some activities. It is heated by a 5 MW th geothermal centralized heat pump. This study proposes a detailed analysis of the thermal demand of 23 selected buildings in this district as a representative panel of buildings meeting high swiss energy performance standards (Minergie A/P) and equipped with different heat recovery systems. Although the buildings have better thermal performance than the average buildings of Geneva, most show an important performance gap between the actual space heating demand and the design values. A strong correlation between performance gap and cut-off temperature of the heating system suggests that the regulation of the heat distribution system plays a determinant role in the overall performance. Regarding the domestic hot water preparation, the buildings of this district present an average demand 23% lower than the standard value and 31% lower than a benchmark.
