B-12 Analysis for Operational Results of Air conditioning system of The Roppongi Hills : No. 4 Verification of the Energy-saving Effect by BEMS Practical Use

Abstract

The BA system of the Roppongi Hiruzu Mori tower is an open network multi vendor system. As the introductory effect, the example of BEMS of the open-ized data practical use which evaluates energy saving and indoor environment, and commissioning (performance verification) of automatic control is introduced. In consideration of the automatic control data of 640 points based on open-izing, the energy-saving effects, such as conveyance power reduction [by cold-water round trip difference-of-temperature reservation], outdoor air cooling effect, and CO2 control effect, are checked. In addition, performance verification of automatic control is tried from the action of VAV immediately after completion.
