Methodology of Measurement and Calculation of Building Energy Management System in University Campus

Abstract

Nowadays, the necessity of university as leader of reducing GHG emission has become an issue of global concern. In this research, we aim to analyze energy system of a model university campus in southern China and grasp the energy consumption of the whole campus from the viewpoint of reducing GHG emission. We investigated and analyzed the present situation of energy system by using measured data and inquiry survey. In order to grasp the data exactly, we introduced building energy management system (BEMS) to some typical buildings with electricity consumption controlling. Firstly, the outlining of the campus and abstract of the buildings were carried out. Secondly, measurement buildings of BEMS in the campus were described according to the results of investigation. Furthermore, methodology of measurement and calculation was researched. The campus's daily electricity consumption and cooling consumption, hourly energy consumption intensity of different typical building, and consumption intensity of different days (weekdays, weekends, and holidays) could be examined using this methodology.
