Night Cooling to Reduce Energy Summery Demand for Indoor Climate Control of Office Buildings
The study here presented focuses on the efficiency of night ventilation coupled with the building thermal mass and associated to an HVAC system for the microclimate control of a typical office room.A typical open space office placed in Rome (Italy) is considered,all along the summer season.Fixing the conditions of indoor temperature during the occupancy period,the evaluation of the effectiveness of the night cooling system is performed,by means of comparison of energy needed with and without the night cooling system.The study has been developed by means of the dynamic simulation of the behaviour of indoor environment;the room has been modelled through the finite differences,and the explicit method has been chosen to solve the energy balances in dynamic conditions.The results show the possibilities of drastic reduction both of energy consumptions for conditioning and of the electrical power needed during the peak hours.
