Abstract: Tel*: +34 963877007 ext. 85247, e-mail*: nipargar@doctor.upv.es There are different methods to estimate the comfort state based on defining a parameter quantifying it. In this work, we present a new managament strategy for a ground coupled HVAC system in a cooling dominated office area. The idea is disminish the electrical consumption while keeping the thermal comfort requirements. This objective is achieved by means of the proper management of some parameters of the system: the air mass flow in the fan, the mass water flow in the internal and external hydraulic circuit and the set point temperature in the water to water heat pump. The electric consumption of the HVAC system is calculated for this new management strategy and compared with the results obtained for a conventional management strategy. In our simulation, the annual electrical energy savings of the ground coupled HVAC system are bigger than the 24% when it is managed by the new one.
