This report presents a summary of the findings and activities of Stage 2 of the LCL-CRC research project RP 1033 “High Performance Commercial Building HVAC”. This research examined the HVAC design of a high performance commercial office building (hereafter referred to as the case study building) and compared its electricity consumption to that of a standard BCA compliant HVAC design for the same building. The main HVAC system designed and installed in the case study building as a low temperature VAV, air-water HVAC system, which is one of the most common designs currently utilised for commercial buildings. The case study building is based on a project completed by AECOM where they were engaged as both the Mechanical Services and ESD consultant. This study was used to gain a better understanding of HVAC design used in high performance buildings verses that required for minimum code compliance.
