Analysis of an Energy-Efficiency Supervision and Diagnostic System for Large Public Buildings in Ji Nan

Abstract

This paper demonstrates an energy-efficiency supervision and diagnostic system (ESDS) to illustrate problems that the buildings do not perform as well as anticipated during design stage. The ESDS consists of a set of sensors, data acquisition system, data analysis and diagnostic system investigated on a web-based remote access system that can be worked to identify problems in practice. The states of monitoring and diagnosing building operations including the electricity consumption、water consumption、overall evaluation of energy consumption and air condition system was analysed in detail. The results show that the energy efficiency of this large public building has great potential during the practice.
