DEVELOPMENT OF GRAPHICAL INDEXES FOR VIEWING BUILDING ENERGY DATA - PART II

Graphs are an effective way of displaying quantitative and statistical information. Unfortunately only a few studies have systematically loo ked at presenting building energy data in forms which are both informa tive, visually efficient and easy to comprehend. Recent advancements i n computing, including the development of sophisticated graphing packa ges and powerful desktop computers have made the concept of graphical displays or graphical indices more timely than ever before. In this tw o part paper, graphical displays or indices are reviewed and discussed that can be used to analyze several years of hourly data (20,000 to 3 0,000 data points). Part I reviewed the literature on graphical presen tations of building energy use data and graphical perception and prese nts two graphical indices. Part II provides four additional graphical indices and a discussion about their effectiveness.
