No. There is no ENERGY STAR score for restaurants.
The majority of ENERGY STAR scores were developed using the Commercial Building Energy Consumption Survey (CBECS) data. However, CBECS does not have adequate information about restaurants to create an ENERGY STAR score because:
- There is limited breakdown by restaurant type.
- There are no questions on types of cooking equipment, which would possibly allow for an assessment of different restaurant business models.
In 2013-2015 EPA undertook an effort to collect restaurant data in coordination with the Department of Energy (DOE), the National Restaurant Association, the Restaurant Facility Management Association, and the PG&E Foodservice Technology Center. DOE led the development and implementation of a survey on restaurant energy use, which divided restaurants into 5 categories based on service level and asked questions on over 15 different types of cooking equipment, including different types of ovens, broilers, and ranges. Unfortunately, we did not receive a sufficient number of survey responses to develop an ENERGY STAR score. In the full service restaurant categories, we only received data from two organizations, which is inadequate for an ENERGY STAR score. In the limited service restaurant categories, we received data from a more diverse set of organizations, but we received data from fewer than 100 individual restaurants, which is inadequate to develop an ENERGY STAR score. EPA and DOE greatly appreciate the time and effort of everyone who did participate in the survey. Although we are not able to offer a score, we hope you will benchmark in Portfolio Manager to continue to improve performance relative to the national median.
Based on the limited data we received, we were able to discern some basic trends. In particular, we saw a strong correlation between number of workers and number of transactions, and between number of workers and Source EUI. This suggests that number of workers may be a more relevant measure of business activity than was previously thought for this sector. In general, the data we received suggests that a meaningful ENERGY STAR score could be developed if a more complete data set were available.
An ENERGY STAR score requires a large, robust, nationally-representative survey. If a more robust survey for restaurants becomes available, we will gladly review the data to assess the possibility of an ENERGY STAR score.
