Estimating a Building’s Energy Performance using a Composite Indicator: A Case Study

Several studies have analyzed the integration of energy-saving strategies in buildings to mitigate their environmental impact. These focused mainly on a disaggregated analysis such and effects building's energy consumption thermal behavior, using engine simulation software (EnergyPlus, TRNSYS, DOE2) or graphical interface (DesignBuilder, eQuest, ESP-r). However, are complex systems whose behavior depends interaction passive (e.g., location construction materials) dynamic occupation) components. Therefore, this study proposes composite indicator Building’s Energy Performance (BEP) as an alternative deal with multidimensional phenomenon simplified way. This considers efficiency comfort. The Electrical Engineering Building (EEB) Universidad Industrial de Santander was selected verify performance BEP indicator. In addition, sensitivity performed for different mathematical aggregation methods weighting values test suitability reproduce building behavior. Different scenarios modeled DesignBuilder were proposed, which integrated individually analyzed. results confirmed that improved by approximately 16%. It has also been possible adequately reproduces building’s while guaranteeing comfort conditions. Finally, is expected contribute sustainability criteria design remodeling stages buildings.
