Toward NZEB by optimizing HVAC system configuration in different climates

Finding the most appropriate matching between envelope features and HVAC system configurations in function of different climates results fundamental for minimizing buildings' energy consumptions. The research aims at presenting the most energy-performing HVAC system configurations for high-performing buildings. Different configurations were modeled for new non-residential Reference Buildings in seven European cities, using dynamic simulation software EnergyPlus and some evaluation tools specifically set to emulate the energy performance of some specific HVAC technologies. Finally, the results obtained were compared in order to outline some conclusions, useful as guidelines for optimizing the choice of HVAC systems in function of climate conditions.
