Technical Reference: ENERGY STAR Score for U.S. Vehicle Dealerships
This document presents details on the development of the 1 – 100 ENERGY STAR Score for vehicle dealerships, which applies to buildings used for the sale of new or used light-, medium- and heavy-duty cars and trucks. The objective of the ENERGY STAR score is to provide a fair assessment of the energy performance of a property relative to its peers, considering 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 vehicle dealerships applies to buildings used for the sale of new or used light-, medium- and heavy-duty cars and trucks.
- Reference Data. The analysis for vehicle dealerships is based on data from an industry survey conducted by the National Automobile Dealers Association (NADA) for the 2019 calendar year.
- Adjustments for Weather and Business Activity. The analysis includes adjustments for:
- Number of Workers on the Main Shift
- Average Number of Vehicles in Inventory
- Heating and Cooling Degree Days
- Percent of the Building that is Heated and Cooled
- Release Date. The ENERGY STAR score for vehicle dealerships is updated periodically as more recent data becomes available:
- Most Recent Update: August 2023.
More information on the overall approach to develop ENERGY STAR scores is covered in our Technical Reference for the ENERGY STAR Score.
