Abstract
Hospitals consume large amounts of energy due to its operation characteristic. The HVAC system designed in hospital buildings runs 24 hours and has special air supply requirements. This study aims to evaluate the energy-saving efficiency of HVAC system by studying two Taiwan’s green hospital buildings. Results show 39.3% energy saving efficiency based on integrating VFD (Variable Frequency Drive) chiller, VAV (Variable Air Volume) system and VWV (Variable Water Volume) system for an existed hospital buildings. Verification shows eQUEST simulation results are within 7% margin of error. The new-built hospital is evaluated based on appropriate parameter assumptions and life-cycle analysis (LCA). Four cases are generated based on different chiller capacity designs. Four cases are estimated to reduce 40% energy consumption compared to baseline model. It is concluded that the optimum chiller capacity design are two 300RT chillers with investment cost of 8,848,400 NTD and life-cycle cost of 69,150,134 NTD. Total payback period is four years. To sum up, this study demonstrates the integration of computer simulat1ion and LCA in evaluating green hospital buildings, and the HVAC energy-saving performance for hospitals proposed in Taiwan’s green building policy is approximately 40%.
