This study investigated the thermal and indoor environmental performance of an office building in the northeast of England. The building was built using natural stone and glass; internally the large floor plates are bordered and penetrated by open voids that ventilate the building and provide exceptional day lighting. A computational model for this building was set up using Design Builder software. The model is validated using on-site monitoring data and then it is used to predict and evaluate the performance of the building. It is found that the U-value of glass and natural stone is relatively high that caused high energy consumption. To achieve the performance recommended by passive house standard, two scenarios are proposed and simulated. It is found that when the window size is reduced and low U-value wall materials used, the energy consumption for heating can be reduced by 33.9% for Scenario 1 and 45.7% for Scenario 2 in a year.
