Abstract: In low energy residential buildings, the energy consumption for hot water generation becomes the main consumption item. In order to achieve the requirement of the new French thermal regulation [1], the consortium has developed a strategy to design a system of DHW generation on the basis of a thermodynamic system using heat sources available in and around the building. This plan is based on numerical simulation tools and field tests. This article shows that first field tests are in agreement with numerical simulations. Reaching the objectives require to minimize heat losses, high COP and possibly having recourse to renewable energies or energy recovery (grey water) or new sources of energy (hot air in attic or warm air in building basement).
