Case study of green energy system design for a multi-function building in campus

The energy system design for a multi-function building in Shanghai Jiao Tong University (SJTU) is presented in this paper. In order to meet the different demands of office, laboratories and demonstration test apartments in this building, three kinds of energy systems, namely main system, parallel system and independent system, are designed. These systems which combine HVAC technology and renewable energy application are discussed and analyzed based on calculation load of room, schedule of occupants and purpose of experiment. The features, working principal and evaluation of typical systems are also provided. One integrated solution for one “net zero energy” apartment which is on the 3rd floor of this building is also introduced in brief. Finally the performance of whole energy system was evaluated by energy-saving ratio, ratio of renewable energy and CO2 emission reduction.
