Abstract
The potentiality of geocooling with borehole heat exchangers is analysed for low energy office buildings. A dynamic thermal simulation tool has been developed to simulate the overall system and the interconnected thermal interactions, including the building, the thermal energy emission, the technical installation and the borehole heat exchanger field. Building design, system technical feasibility and limits of the ground coupled system are discussed and result from the analysis of the numerous system simulations. Geocooling potential depends on the quality of the building design and its heat emission. The importance of the ground recharge ratio on the system design is highlighted. Simple design sizing keys are proposed for a fast pre-sizing of a borehole field for geocooling.
