Abstract

The aim of this study is to form the basis of a further analysis on night ventilation for cooling purposes in modern Swedish office buildings. An existíng Swedish office building with night ventilation has; been monitored and a complementary study on building energy end-uses with the help of the DOE-2 building simulation program. has been carried out. Measurements show that the building's energy usage is on a low level regarding thermal as well as electrical energy end use. The total annual electricity use in the office building studied i.e. by fans, office lighting, equipment and elevators, amounted to 57 KWh/m2 office area. In order to makc a comprehensive study on night ventilation, the detailed performance of the simulation model needs further calibration, although an acceptable agreement between measured and simulated electricityu sage on a monthly basis is achieved. Irregular occupancy, manual air-handling system operation (especially night ventilation control) and partly unsuitable default fan part load curves in the DOE-2 model clearly show the need for more detailed analyses in order to hav, e an acceptable agreement between measurements and simulations during the summer period.
