Supermarket Efficiency Measures a ‘Slam-Dunk’ Opportunity


Click Here for Full Article

Refrigeration contractors don’t get many opportunities to “slam dunk,” but when it comes to energy savings opportunities for their supermarket clients, they can soar like NBA all-stars.

Speaking at a recent meeting of the Food Marketing Institute (FMI), Jonathan Tan, director, business development, Hillphoenix, cited statistics from FMI and the U.S. Energy Information Administration (EIA) showing that although supermarkets in the U.S. bring in close to $700 billion in annual revenue, they do so at an average net profit of only 1.7 percent. In addition, although supermarkets make up about 2 percent of total U.S. commercial building space, they account for about 6 percent of total U.S. commercial building energy consumption.

It therefore becomes clear that supermarket owners and operators are going to eagerly lend their ears to contractors who can help them reduce their energy costs. The good news is that there are numerous opportunities to help them do so, especially on the refrigeration side.

“If you’re a supermarket owner or operator and you’re going to invest money somewhere, what better place to put it than into energy efficiency?” Tan asked. “Usually in financial dealings, a high rate of return requires a high risk, but that’s not the case with energy-efficiency investments — they’re low risk and very high return.”

Tan noted the bulk of a typical supermarket’s energy costs are driven by refrigeration. Efficiency variations among stores in a chain can show where the greatest opportunities exist for contractors (see Figure 1). In addition, he presented an energy comparison to illustrate some steps refrigeration contractors can take to help their supermarket customers reduce their energy consumption, save money, and increase their profitability (see Figure 2).

“Sometimes we make it difficult for ourselves and our customers because we can’t nail down the exact worth and value of our energy-efficiency initiatives,” he said.

Tan’s energy comparison showed the value of five simple refrigeration-related energy-efficiency projects at a typical 50,000-square-foot supermarket: placing doors on open refrigeration display cases; retrofitting cases with LED lighting; changing doors with traditionally high door heat to either no-heat or low-heat doors on low-temperature cases; retrofitting fans with electronically commutated motors (ECMs); and installing sweat misers on cases. Prior to any of these actions, the store’s annual electricity consumption for the refrigeration system was $157,000.

“Just by adding doors, I immediately take 80 percent of the Btu out of the medium-temperature cases,” Tan said. “That’s about a 24 percent reduction in power on the refrigeration side right off the top.”

He added that doors also make the refrigerated aisles more comfortable for shoppers and reduce the burden on a store’s HVAC system.

Retrofitting freezer cases with LED lighting saves another 5 percent, and converting fan motors from shaded pole or split capacitor motors to ECMs saves another 4 percent.

There’s also an opportunity for savings by installing low-heat or no-heat doors. According to Tan, many stores today have heat on the door and heat in the frame — in some cases 250 W or more per door.

However, today’s better technology in insulation and glass can allow many stores to switch to no-heat doors and save 250-plus W per door. In areas with high humidity, low-heat doors typically save about 200-212 W per door.

“Taking a refrigerated case and adding heat to it doesn’t make a lot of sense,” Tan said. “By using no-heat or low-heat doors, you’re going to use one-fifth of the energy you were using just to keep sweat off the doors. That’s a big opportunity — about a 10 percent reduction in refrigeration system energy usage — and I’m surprised as I travel around the country to see that more people are not taking advantage of this.”

Another option would be to offer supermarket clients anti-sweat heater controls, which allow the door heaters to be cycled based on the conditions in the store.

In the final analysis, the store that started out with $157,000 in refrigeration-related energy costs can see that number reduced by 43 percent, to $89,000, just by taking those simple steps.

“That provides about $67,000 in savings just on the refrigeration side,” he said. “We’re not talking about the controls, HVAC, or lighting, where there are incrementally more opportunities. When you look at all systems as a whole and make them all work together, your opportunities are even greater than this 43 percent savings.”

If a 43 percent savings doesn’t grab your supermarket clients’ attention, Tan cited U.S. Department of Energy (DOE) statistics that show for every $1 in energy savings that goes to a supermarket’s bottom line, the store would need to sell an additional $18 to add that same dollar.

“That would be more than $1 million in sales or nearly 400 additional single-family shoppers coming through a store per week,” Tan said. “And because demographics are very hard to change around any given store, adding 400 additional single-family shoppers would be a huge challenge.”

Tan also explained there are a number of tools for funding energy-efficiency projects. Contractors can use these tools to leverage projects with their customers. These include utility incentives, on-bill financing, traditional financing, and Property Assessed Clean Energy (PACE) financing.

Utility incentives — These are available from most utilities. They can dramatically reduce the capital required for projects and often cover a multitude of energy efficiency measures. A potential downside is that the projects(s) may need pre-approval to qualify, so it’s important to involve the utility from the beginning.

On-bill financing — This is a powerful tool in which the loan for the energy-efficiency project is paid back by the energy savings on the supermarket’s utility bill. These loans are typically very inexpensive or can be obtained at even 0 percent interest and can provide positive or net-even cash flow. On the downside, they are typically limited to energy-efficiency projects only, have limited availability, and may require capital funding for the initial cash outlay.

Traditional financing — Traditional financing is flexible, readily available, and may improve return on invested capital. Yet, Tan said it has become somewhat of a “bugaboo” in the HVACR industry, stating, “We’ve had some difficulties with how we explain traditional financing. Customers may think, ‘I’m paying 5 percent on this loan, so it’s costing me money,’ but when you factor in the money being saved in energy usage, it’s quite common for a customer to be paying 5 percent on a loan and still saving thousands of dollars each month.”

PACE financing — This is available in 29 states and Washington, District of Columbia. The program offers low interest rates on loans that are repaid through property taxes. According to Tan, these loans are good for heavy capital investment projects that have a long return-on-investment schedule, such as building envelope upgrades or renewable energy. They have a minimum term of five years, so they are less suitable for projects that require little capital or those in which the simple returns on investment are quick.

In summary, contractors have a variety of ways to help their supermarket customers save money through energy-efficiency projects, particularly on the refrigeration side. The key is to explain everything in terms customers can understand.

“Make sure your supermarket clients know the money is available, and the money is cheap, so they should go out and get it while at the same time improving their operations and increasing their profitability. And, when it comes to your upgrades, make it easy for customers to understand. It really is as simple as a Btu is a Btu, and a watt is a watt.”

Supermarket Freezer Doors Energy-Efficient?


When customers open the freezer door at the supermarket, the glass on the inside will fog. When the door is closed again, the next shopper isn’t able to see all of the products inside. Before our anti-fog film, supermarkets had to use energy-sapping door heaters to prevent the fog. Over one year, eliminating the cost of operating these heaters equates to a savings of $70-150 per door each year in the United States.

Our film is incredibly hydrophilic and absorbent — it really, really loves water. Instead of allowing the tiny discrete globules of water to form on the surface that would create fog, the anti-fog film spreads the water out over the surface, keeping it transparent. Our film can stick onto glass, and any flat surface including plastic, stainless steel and aluminum. The possibilities are endless, so call us today to inquire about how we can help you be fog free and more energy-efficient. Visit our website www.AntiFogTechnology for more information or call 941-ANTIFOG.

Pain in the Frozen Food Aisle


A typical customer experience in the frozen food aisle!


Customer A opens the frozen food door to purchase several products. In the meantime that door begins to fog. In less than 25 seconds that door is completely fogged over and literally prevents the next consumer from seeing the product in that freezer case.

Customer B comes along and has two choices; 1. Either walk right past the door because they can’t see what’s inside. 2. They can open the door to view the merchandise which makes the fogging situation even worse.anti-fogtechnology

Your cost while this happens *Possible loss of impulse buy. *Merchandise exposed to extreme differences in temperature. *On average you are spending $100 a year per door in attempt to defrost the glass.

The Moist Truth About Foggy Hotel Mirrors

One clean towel a day to wipe the condensation off a foggy hotel mirror can be costly!

Every year hotel chains spend millions of dollars in electric, water, detergent, and labor cost to ensure our rooms are supplied with clean, comfortable towels for our use. When the mirrors fog in the bathroom, we grab a clean towel and clear the moisture away and then toss it. Even the use of one small hand towel per room based on a hotels occupancy can drive cleaning cost for just that 1 towel to nearly $10K annually. How?

Let’s look at 1 towel. Average hand towel weighs approximately 0.4LBS. Using rule of thumb of 1.5 gallons of water per pound of clothing, that is nearly 1/2 gallon of water. Now add in your cost of detergent and electric to wash and dry, you are looking at approximately $0.06 per day to clean that 1 towel. That works out to be just about $22 per year to wash and dry that 1 towel every day. Now, looking at a 550 room hotel in NYC with 80% occupancy rate, that works out to be about 440 times that cost, or nearly $10,000 (below is a sample NYC Hotel we used to calculate costs).

Anti-Fog Technology uses a natural film that is optically clear, inherently hydrophilic, and extremely absorbent. Our technology has been verified by many of the largest utility companies in the country. In addition, we have been able to receive substantial rebates.

Combating Moisture on Glass with Heat?

If you are like most companies, you are battling moisture on glass with heat which requires energy. Energy costs money and is not sustainable. Up until now, there hasn’t been a zero-energy solution.

Anti-Fog Technology recently discovered a way to combat moisture with a low-cost innovative product. Our technology uses a natural film that is optically clear, inherently hydrophilic, and extremely absorbent. Our technology has been verified by many of the largest utility companies in the country. In addition, we have been able to receive substantial rebates.

One of our customers spoke at a recent conference and stated, “We are  saving 47% off our refrigeration costs using Anti-Fog’s film.” Not only can this technology be used for low-temp freezer doors, but on hotel mirrors that fog.

There are big savings for the hotel industry or any industry that uses glass and battles moisture. Below is a valuation we did for a hotel in New York City using just one towel a day to wipe off the foggy mirrors in the bathroom (you know you’re guilty of this too). By using one towel a day; detergent, water and utilities are factored in. The savings speak for themselves.

Moisture On Glass? Problem Solved!


How We Solved That Problem with Anti-Fog Technology

Anti-Fog Technology at work! Here is what we did for one of our grocery store clients.

On the left you will see doors that have anti-fog film on them, on the right all those cases are NOT treated with anti-fog film. Because anti-fog technology’s film is naturally hydrophilic and absorbent, it absorbs the moisture on the doors. It’s also a zero-energy solution allowing grocery stores to disconnect the sweat heater to the glass, saving energy at the same time, providing a clear view for customers. A clear solution for moisture on glass ( This technology can be used on any glass that fogs, including hotel mirrors).
