THE APPLICATION OF BUILDING ENERGY SIMULATION AND CALIBRATION IN TWO HIGH-RISE COMMERCIAL BUILDINGS IN SHANGHAI
Yiqun Pan, Zhizhong Huang, Gang Wu, Chen Chen
The method of calibrated computer simulation is summarized and introduced based on related literatures and guidelines, which is used to analyze the energy consumption of two high-rise commercial buildings in Shanghai, China. The detailed data of the buildings and systems are collected and input to build up models with DOE-2, then the output of simulation is compared to the measured energy consumption data to refine and calibrate the models. Several energy conservation measures (ECMs) are analyzed based on the calibrated models, including using variable speed chilled water pumps instead of constant variable speed ones, using free cooling during winter and mild seasons, replacing old low efficiency cooling towers with new high efficiency ones, decreasing lighting power densities. Energy saving performance is simulated and calculated to find out which ECM is the best option for each building.
