Commercial refrigeration spans food sales, food service, retail, storage and other commercial buildings. The available U.S. statistics below distinguish modeled 2012 refrigeration-electricity intensity, 2018 whole-building energy totals, current ENERGY STAR savings estimates and EPA typical-system leakage estimates.

Commercial Refrigeration Energy Use in U.S. Buildings
The 2018 Commercial Buildings Energy Consumption Survey represented an estimated 5.9 million U.S. commercial buildings. Across that population, EIA estimated 6.8 quadrillion Btu of total energy consumption and $141 billion in total energy spending in 2018; neither figure isolates refrigeration. EIA, CBECS 2018 final results
Refrigeration-specific figures come from EIA’s 2012 modeled end-use table. The measure is electricity energy intensity in thousand Btu per square foot among buildings using electricity for refrigeration, with floorspace—not refrigerated case footage—as the denominator. EIA, Table E4: Electricity consumption intensities by end use, 2012
| Building activity | Refrigeration electricity intensity, 2012 | Population and measure |
|---|---|---|
| All listed commercial buildings | 9.1 thousand Btu/sq. ft. | U.S. buildings using electricity for refrigeration |
| Food sales | 117.6 thousand Btu/sq. ft. | U.S. food-sales buildings |
| Food service | 62.4 thousand Btu/sq. ft. | U.S. food-service buildings |
| Retail other than malls | 11.8 thousand Btu/sq. ft. | U.S. retail buildings |
| Enclosed and strip malls | 23.6 thousand Btu/sq. ft. | U.S. malls |
| Warehouse and storage | 5.4 thousand Btu/sq. ft. | U.S. warehouse and storage buildings |
| Office | 2.0 thousand Btu/sq. ft. | U.S. office buildings |
| Health care | 4.6 thousand Btu/sq. ft. | U.S. health-care buildings |
These are CBECS modeled estimates, not direct meter readings for refrigeration equipment. EIA’s modeling uses reported refrigerator counts and building type but generally lacks refrigerator size, so the values should not be read as equipment-level performance results.
Commercial Refrigeration Electricity Data by Building Size and Activity
Building size does not move in a simple straight line with modeled refrigeration intensity. In 2012, the highest listed size-band estimate was 24.0 thousand Btu per square foot for buildings of 1,001–5,000 square feet, while buildings over 500,000 square feet averaged 3.2 thousand Btu per square foot. EIA, Table E4
| Building floorspace | Refrigeration electricity intensity, 2012 |
|---|---|
| 1,001–5,000 sq. ft. | 24.0 thousand Btu/sq. ft. |
| 5,001–10,000 sq. ft. | 14.2 thousand Btu/sq. ft. |
| 10,001–25,000 sq. ft. | 8.4 thousand Btu/sq. ft. |
| 25,001–50,000 sq. ft. | 6.8 thousand Btu/sq. ft. |
| 50,001–100,000 sq. ft. | 8.4 thousand Btu/sq. ft. |
| 100,001–200,000 sq. ft. | 8.1 thousand Btu/sq. ft. |
| 200,001–500,000 sq. ft. | 6.8 thousand Btu/sq. ft. |
| Over 500,000 sq. ft. | 3.2 thousand Btu/sq. ft. |
The activity comparison is also important: food-sales buildings averaged 117.6 thousand Btu per square foot, compared with 62.4 thousand Btu per square foot for food-service buildings. Food-service buildings used 153.2 thousand Btu per square foot across all listed electricity end uses, which is a total electricity-intensity measure rather than refrigeration alone. EIA, Table E4
Commercial Refrigeration Trends by Building Age, Region and Climate
The 2012 modeled estimates vary across construction-year groups, but they do not establish that building age caused the differences. The highest listed value was 11.7 thousand Btu per square foot for buildings constructed from 2004–2007; buildings constructed before 1920 averaged 5.0 thousand Btu per square foot. EIA, Table E4
| Construction period | Refrigeration electricity intensity, 2012 |
|---|---|
| Before 1920 | 5.0 thousand Btu/sq. ft. |
| 1920–1945 | 6.8 thousand Btu/sq. ft. |
| 1946–1959 | 6.5 thousand Btu/sq. ft. |
| 1960–1969 | 7.9 thousand Btu/sq. ft. |
| 1970–1979 | 10.0 thousand Btu/sq. ft. |
| 1980–1989 | 9.0 thousand Btu/sq. ft. |
| 1990–1999 | 11.1 thousand Btu/sq. ft. |
| 2000–2003 | 8.8 thousand Btu/sq. ft. |
| 2004–2007 | 11.7 thousand Btu/sq. ft. |
| 2008–2012 | 10.9 thousand Btu/sq. ft. |
Regional estimates ranged from 7.7 thousand Btu per square foot in the Midwest to 9.7 thousand Btu per square foot in both the South and West. The Northeast averaged 8.9 thousand Btu per square foot.
Climate-region estimates were 10.6 thousand Btu per square foot in hot-humid buildings and 8.6 thousand Btu per square foot in very-cold/cold buildings. EIA, Table E4
Commercial Refrigeration Statistics by Floors, Staffing and Hours
Building form and staffing bands also show variation in the 2012 EIA estimates. One-story buildings averaged 14.0 thousand Btu per square foot, compared with 3.1 thousand Btu per square foot for buildings with 10 or more floors. EIA, Table E4
| Building characteristic | Refrigeration electricity intensity, 2012 |
|---|---|
| One story | 14.0 thousand Btu/sq. ft. |
| Two stories | 7.4 thousand Btu/sq. ft. |
| 10 or more floors | 3.1 thousand Btu/sq. ft. |
| Fewer than 5 main-shift workers | 9.0 thousand Btu/sq. ft. |
| 5–9 main-shift workers | 10.6 thousand Btu/sq. ft. |
| 10–19 main-shift workers | 12.1 thousand Btu/sq. ft. |
| 20–49 main-shift workers | 11.1 thousand Btu/sq. ft. |
| 250 or more main-shift workers | 4.4 thousand Btu/sq. ft. |
| Fewer than 40 operating hours per week | 3.4 thousand Btu/sq. ft. |
| 40–48 operating hours per week | 3.0 thousand Btu/sq. ft. |
These staffing and operating-hour bands are subgroup estimates, not evidence that staffing or hours alone determine refrigeration intensity. Separately, DOE’s 2014 commercial-refrigeration standards analysis treated equipment as operating 24 hours per day, an analytical assumption for national savings modeling rather than a measured operating-hours survey.

Commercial Refrigeration Efficiency, Savings and Equipment Performance
ENERGY STAR’s current commercial refrigerators and freezers page, accessed in 2026, says certified products are on average 20% more energy efficient than standard models. Its figures are modeled comparisons for covered certified product classes, so actual savings depend on equipment, use and utility rates. ENERGY STAR, Commercial Refrigerators & Freezers
| Certified product class | Estimated annual electricity savings | Estimated bill savings or lifetime outcome |
|---|---|---|
| Solid-door commercial refrigerator | 325 kWh | More than $40 annually; $350 over product lifetime |
| Glass-door commercial refrigerator | 370 kWh | Nearly $50 annually |
| Solid-door commercial freezer | 80 kWh | Annual electricity figure reported |
| Glass-door commercial freezer | 900 kWh | More than $110 annually; $980 over product lifetime |
ENERGY STAR presents these as modeled savings versus standard models. The page does not make them universal measured averages for every installation, and utility-bill amounts can vary with electricity rates.
Commercial Refrigeration Refrigerant Leakage and Environmental Outcomes
EPA’s fact sheet describes a typical supermarket refrigeration system as holding about 4,000 pounds of refrigerant and estimates an average annual leak rate of about 25% of the charge. EPA’s associated approximation is approximately 1,000 pounds of refrigerant emitted each year for that typical system; it is not a census average and should not be generalized to every store. EPA, Prioritizing Leak Tightness During Commercial Refrigeration Retrofits
EPA also reports that GreenChill food-retail partners have refrigerant-emissions rates nearly 50% lower than the EPA-estimated industry average. The comparison concerns program partners, whose stores may differ from the broader industry. EPA, Prioritizing Leak Tightness During Commercial Refrigeration Retrofits
If every U.S. supermarket joined GreenChill and matched the current GreenChill average, EPA estimated $108 million in annual industry savings. This is a scenario estimate, not realized national savings. EPA, Prioritizing Leak Tightness During Commercial Refrigeration Retrofits
