Abstract:
The objective of this research is to evaluate the energy savings performance of an energy-saving building on a university campus. Two types of energy saving technologies are employed in this building to reduce energy consumption. The first is passive design technologies, which save energy through creative design such as the arrangement and choice of materials in the building. The other type is active equipment for saving energy, such as photovoltaic power cells and solar collectors. The individual energy saving performances of the deployed technologies are clarified through simulations and actual measurements. Simulations are carried out using the Energy Plus software. The effects from the passive design technologies are estimated by calculating the heating and cooling loads. The heating and cooling loads are found to be reduced by approximately 10{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} by the use of passive design technologies. Actual measurements on the active equipment showed that the generated photovoltaic power can supply approximately 90{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} of the lighting consumption.
