ENERGY STAR Score for Medical Offices

The ENERGY STAR Score for Medical Offices applies to facility space used to provide diagnosis and treatment for medical, dental, or psychiatric outpatient care. 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.

  • Property Types. The ENERGY STAR score for medical offices applies to facility space used to provide diagnosis and treatment for medical, dental, or psychiatric outpatient care. The score applies to individual buildings only and is not available for campuses.
  • Reference Data. The analysis for medical offices is based on data from the Department of Energy, Energy Information Administration’s 1999 Commercial Building Energy Consumption Survey (CBECS).
  • Adjustments for Weather and Business Activity. The analysis includes adjustments for:
    • Square Footage
    • Number of Workers
    • Hours of Operation per Week
    • Weather and Climate (using Heating and Cooling Degree Days, retrieved based on Zip code)
    • Percent of the Building that is Heated and Cooled
  • Release Date. The ENERGY STAR score for medical offices was released in February 2004.

This document presents details on the development of the 1 - 100 ENERGY STAR score for medical office 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 www.energystar.gov/ENERGYSTARScore. The subsequent sections of this document offer specific details on the development of the ENERGY STAR score for medical offices.
