ENERGY STAR score for hospitals (general medical and surgical) (Canada)

This picture shows the first page of the ENERGY STAR score for hospitals in Canada document.

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 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. A statistical analysis of the peer building population is performed to identify the aspects of building activity that are significant drivers of energy use and then to normalize for those factors. The result of this analysis is an equation that predicts 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.


 

  • Property types. The ENERGY STAR score for hospitals 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 is based 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, and represents consumption year 2009.
  • Adjustments for weather and business activity. The analysis includes adjustments for:
    • Building size
    • Licensed hospital bed capacity
    • Number of workers on the main shift
    • Presence of on-site laundry facility
    • Weather and climate (using heating and cooling degree days, retrieved based on postal code)
    • Percent of the building/campus that is heated and cooled
  • Release date. The ENERGY STAR score for Canadian hospitals was released in May 2014.

This document presents details on the development of the 1 – 100 ENERGY STAR score for hospital properties. More information on the overall approach to develop ENERGY STAR scores is covered in our Technical Reference for the ENERGY STAR Score, available at http://www.energystar.gov/ENERGYSTARScore. The subsequent sections of this document offer specific details on the development of the ENERGY STAR score for hospitals.
