Comparing Building Energy Performance Measurement

Share this Post:

Building energy performance is a measure of efficiency, but diverse measures of performance are used around the world, and they are largely local in application. Overall, there is a lack of understanding of how building energy efficiency compares across markets. This kind of comparison is increasingly useful for regions to compare building performance and exchange best practices.
 
This paper proposes a classification for energy performance and classification systems, analyzing 17 different systems in 10 countries. Each system is evaluated by the approach to six basic underlying characteristics: energy consumption, energy type, building floor area, building type, performance scale, and energy uses. This framework reveals that the systems are diverse, and none of those studied uses the same methodology. Upon further analysis it can be concluded that:

 The goal of the report is not standardization of systems but rather a standard framework of comparison, a common set of terms and characteristics that can explain any system.
