Analysis of energy data of existing buildings in a University Campus

Abstract

The constant increase in the requirement for electric energy on the part of the service sector has driven the development of tools for the analysis of energy data regarding the management of buildings. Particularly university campuses are made up of buildings for different purposes and uses. Therefore, this work proposes to develop a method capable of providing clear and easy-to-understand information to track electricity end-use by means of two-dimensional graphs. The aim of the method is to analyse the data of the electricity consumption of one or several buildings and compare them with regard to their surface areas and uses, as well as to obtain a correlation with the outdoor temperature. The visual analysis of the building electricity consumption in the campus ‘Sciences et Technologies’ of the University of Bordeaux in France is based on graphs which include electricity use intensity, time series of daily electricity consumption, scatter diagrams of consumption versus heating degree-days, and boxplots for daily consumption profiles. This analysis permits characterising the electricity consumption of the different types of buildings and determining a trends of energy end-use in the short as well as in the long term.
