Design and commissioning of the low-energy office building in Prague

This paper deals with the use of computer simu-lations both for design support of a new build-ing including its heating, ventilation and air-conditioning (HVAC) systems and for optimiza-tion of the HVAC control strategy during opera-tion of the completed building. In the early design phases for a new com-mercial building in Prague computer simula-tions were carried out in view of possible effects of night cooling ventilation. Predictions of the indoor environment and energy consumption for various options regarding cooling capacity and different outdoor ventilation rates supported the HVAC system design which included daytim
