ENERGY STAR score for hospitals (general medical and surgical) (Canada)
The ENERGY STAR Score for Hospitals in Canada applies to general medical hospitals, including critical access hospitals and children’s hospitals. The objective of the ENERGY STAR score is to fairly assess how a property’s energy use measures up against similar properties considering the climate, weather, and business activities. A statistical analysis of the peer building 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 – 100 percentile ranking in relation to the national population of properties.
Property types. The ENERGY STAR score for hospitals in Canada applies to general medical hospitals, including critical access hospitals and children’s hospitals. The ENERGY STAR score applies to an entire hospital, whether it is a single building or a campus of buildings. Individual buildings that are part of larger hospital campuses cannot receive their own score.
Reference data. The analysis for hospitals in Canada relies on data from the Survey on Commercial and Institutional Energy Use (SCIEU), which was commissioned by Natural Resources Canada (NRCan) and carried out by Statistics Canada. The SCIEU represents the energy use for the year 2014.
Adjustments for weather and business activity. The analysis includes adjustments for:
- Gross floor area used for food preparation
- Number of sterilization units
- Number of Magnetic Resonance Imaging (MRI) machines
- Number of workers on the main shift
- Weather and climate (using heating degree days, retrieved based on postal code)
Release date. This is the second release of the ENERGY STAR score for hospitals in Canada. The ENERGY STAR score for hospitals is updated periodically as more recent data becomes available:
- Most Recent Update: August 2020
- Original Release: August 2015
