ENERGY STAR Score for Hotels
The ENERGY STAR Score for Hotels applies to properties renting overnight accommodations on a room/suite and nightly basis. 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 hotels applies to properties renting overnight accommodations on a room/suite and nightly basis. The score applies to an entire hotel whether it is a single building or a campus of buildings.
- Reference Data. The analysis for hotels is based on data from the Department of Energy, Energy Information Administration’s 2003 Commercial Building Energy Consumption Survey (CBECS).
- Adjustments for Weather and Business Activity. The analysis includes adjustments for:
- Building Size
- Number of Rooms
- Number of Workers
- Number of Commercial Refrigeration Units
- Presence of a Commercial Food Preparation Area
- 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 hotels is updated periodically as more recent data becomes available:
- Most Recent Update: February 2009
- Original Release: April 2002
This document presents details on the development of the 1 - 100 ENERGY STAR score for hotel 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.
