ENERGY STAR Score for Retail Stores in Canada

Last Updated: 08-26-2019

The ENERGY STAR score for retail stores applies to both retail stores and wholesale club/supercenters. The objective of the ENERGY STAR score is meant to fairly assess how a property’s energy use measures up against similar properties considering the climate and business activities. A statistical analysis of the peer population is performed to identify the aspects of property activity that are significant drivers of energy use and to normalize for those same factors. The result of this analysis is an equation that predicts the energy use of a property, based on its business activities. This prediction is compared to the property’s actual energy use to yield a 1 to 100 percentile ranking in relation to the national population of properties.

ENERGY STAR Score for Offices

Last Updated: 07-22-2019

The ENERGY STAR Score for Offices applies to office, bank branch, financial office, and courthouse property types. The objective of the ENERGY STAR score is to provide a fair assessment of the energy performance of a property relative to its peers, taking into account the climate, weather, and business activities at the property. To identify the aspects of building activity that are significant drivers of energy use and then normalize for those factors, a statistical analysis of the peer building population is performed. The result of this analysis is an equation that will predict the energy use of a property, based on its experienced business activities. The energy use prediction for a building is compared to its actual energy use to yield a 1-to-100 percentile ranking of performance, relative to the national population.

ENERGY STAR Score for Wastewater Treatment Plants

Last Updated: 08-24-2018

The ENERGY STAR Score for Wastewater Treatment Plants applies to primary, secondary, and advanced treatment facilities with or without nutrient removal capacity. The objective of the ENERGY STAR score is to provide a fair assessment of the energy performance of a property relative to its peers, taking into account the climate, weather, and business activities at the property. To identify the aspects of building activity that are significant drivers of energy use and then normalize for those factors, a statistical analysis of the peer building population is performed. The result of this analysis is an equation that will predict the energy use of a property, based on its experienced business activities. The energy use prediction for a building is compared to its actual energy use to yield a 1 to 100 percentile ranking of performance, relative to the national population.

ENERGY STAR Score for Multifamily Housing in the United States

Last Updated: 08-24-2018

The ENERGY STAR Score for Multifamily Housing applies to buildings that contain 20 or more residential living units. The objective of the ENERGY STAR score is to provide a fair assessment of the energy performance of a property relative to its peers, taking into account the climate, weather, and business activities at the property. To identify the aspects of building activity that are significant drivers of energy use and then normalize for those factors, a statistical analysis of the peer building population is performed. The result of this analysis is an equation that will predict the energy use of a property, based on its experienced business activities. The energy use prediction for a building is compared to its actual energy use to yield a 1 to 100 percentile ranking of performance, relative to the national population.

Portfolio Manager Technical Reference: ENERGY STAR Score

Last Updated: 08-24-2018

EPA’s 1 - 100 ENERGY STAR score is an external benchmark for assessing the performance of commercial buildings. The ENERGY STAR score, expressed as a number on a simple 1 - 100 scale, rates performance on a percentile basis: buildings with a score of 50 perform better than 50% of their peers; buildings earning a score of 75 or higher are in the top quartile of energy performance. First introduced in 1999, the score has been adopted by leading organizations across the United States because it offers a simple way to evaluate measured energy use, prioritize investments, and communicate relative performance across a portfolio of buildings. In July of 2013, the Environmental Protection Agency (EPA) and Natural Resources Canada (NRCan) together released the first 1 - 100 ENERGY STAR score for Canadian buildings, which applies the same methodology to assess measured performance relative to Canadian building stock. Within each section of this document, distinctions between the U.S. and Canadian methodologies are noted.
