APPLICATION OF THE AIR-CONDITIONING SYSTEM ENERGY SIMULATION FOR COMMISSIONING (ACSES/CX) TOOL TO HVAC SYSTEM COMMISSIONING Part 1: Explanation of ACSES/Cx and Application to Design Stage Commissioning of a Large Heat Source Plant

Commonly provided HVAC system simulation tools are not necessarily satisfactory for the investigation of operational improvement and renovation planning because the effectiveness of using a large amount of measurement data accumulated in a Building Energy Management System (BEMS) is limited. For example, although evaluation of refrigerator based on the actual thermal load would be useful for operational performance improvement and decision making of renovation design, this type of investigation is usually very difficult due to the limited features of simulation tools. In the present study, we first explain the specific features of the Air-Conditioning System Energy Simulation for Commissioning (ACSES/Cx) tool for HVAC system simulation, which was specially developed for use in the commissioning process. The results of applying ACSES/Cx to design stage commissioning for the renovation of an existing large-scale heat source plant are then presented.
