Energy benchmarking for supermarkets and food stores


Energy use in supermarkets and food stores

Supermarkets are among the most energy-intensive commercial buildings. Their high energy consumption is largely attributed to refrigeration and HVAC. Energy costs are typically approximately 1% of sales, which is about the same as a store’s overall profit margin.Footnote 1

Drive up your competitive edge by reducing your energy consumption

In order to maintain your competitive edge in the food retail sector, consider a strategic plan to managing the energy in your store that starts with energy benchmarking. Energy benchmarking is a key best practice and the foundation for an effective energy management and decision-making plan. It is often an overlooked tool, yet once incorporated into your tool kit, it provides data that you can use to identify poorly performing buildings, invest strategically in energy efficient upgrades and track the effectiveness of the improvements undertaken.

Energy benchmarking – the basics

Why benchmark with ENERGY STAR Portfolio Manager?

Demonstrate your environmental leadership

Energy efficiency is one of the top sustainability priorities for many Canadian businesses. Many Canadian food retailers are committed to demonstrating effective energy management as solid stewards of resources and to minimize overhead costs in order to maintain low prices for their customers.

Benchmarking your store’s energy use with the free online ENERGY STAR Portfolio Manager tool can support your organization’s sustainability initiatives. The tool provides an energy use baseline and a statistically valid benchmark created specifically for Canadian supermarkets and other food retailers that you can use to develop a compelling case for investments in energy measures in your supermarket or food store through building recommissioning, energy retrofits, or even simple scheduling or behavioural changes.

Benchmarking: a critical first step

Benchmarking can be a valuable tool in moving beyond national average performance to best-in-class performance. 

In 2013, Natural Resources Canada introduced ENERGY STAR Portfolio Manager, a free invaluable business planning tool, to Canada. To learn more about why your store should benchmark with ENERGY STAR Portfolio Manager, read on:

A trend that is catching on

Thousands of other building types in Canada are already using the tool and are reaping the rewards of responsible energy use. Now the food retail sector in Canada can join the growing number of Canadian building owners and managers who have already reduced their energy bills by tens of thousands of dollars per year.

According to the U.S. Environmental Protection Agency’s Data Trends, in the U.S. more than 15,500 supermarketsFootnote 2  are benchmarking their energy performance with an average annual energy savings of more than 2%.Footnote 3 Just imagine what your store could do with 2% of its energy budget.

What you need to know before you benchmark your supermarket or food store

The ENERGY STAR Score for Supermarkets and Food Stores in Canada applies to supermarkets, grocery stores, food sales and convenience stores with or without gas stations, but does not apply to restaurants.

To obtain a 1-100 ENERGY STAR score, in addition to your store’s basic tombstone information, you need the following building data:

  • Gross floor area
  • Number of cash registers
  • Number of computers
  • Number of workers on the main shift
  • Length in meters of refrigerated/frozen food display cases
  • Postal code (to retrieve the weather data for your location)
  • 12 consecutive months of energy use data*
    • Specific energy billing information for each building for all purchased energy. You will need to begin with at least 12 consecutive months for each energy source and update regularly with monthly usage data.

*You do not need 12 months of energy use data to start benchmarking. You can start using the tool to track your energy performance no matter how much accumulated data you have. However, in order to obtain the 1-100 score or an energy use intensity, you need 12 months.

ENERGY STAR Score for supermarkets and food retail in Canada

Start ranking your performance

With the release of Natural Resources Canada’s newest ENERGY STAR score, supermarkets and food stores across Canada can now rank their energy-efficiency performance against other similar competitors.

What you can do to maintain and improve your store’s 1-100 ENERGY STAR score:

  • input new energy data regularly (monthly or quarterly)
  • review data for accuracy
  • use Portfolio Manager’s Data Quality Checker tool
  • review and update data to reflect changes in building characteristics/use at least quarterly
  • review reports and graphs regularly to identify trends and interpret data

The ENERGY STAR score provides 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. The ENERGY STAR scores for the food retail sector in Canada are based on data obtained from the Survey of Commercial and Institutional Energy Use - Buildings 2009 [PDF – 3.7 MB], a national survey of 2009 energy consumption conducted by Statistics Canada in 2010.
