Abstract
Building energy efficiency analysis based on simulation tool and BEMS is very important for saving energy and reduction of CO_2 emission. This paper presents a study of HVAC system simulation of a real office building in Hong Kong.For energy conservation of the chiller plant, a model is built in simulation tool LCEM. The base model is first calibrated by comparing the simulation result of energy consumption with the measured data from BEMS. After calibration of the model, several operation improvements for saving energy are given based on the simulation result.
