[Webinar Recap] Preparing for the DOE’s New WICF Energy-Efficiency Standards

Julie Havenar | Product Manager – Condensing Units
Emerson Commercial & Residential Solutions

I recently conducted an E360 Webinar about the Department of Energy’s (DOE) new energy-efficiency standards on walk-in coolers and freezers (WICF). The webinar was presented to help industry stakeholders prepare for compliance by reviewing the ruling’s scope, definitions and potential industry impacts. View an archive of the webinar here and/or read a summary of its key takeaways below.

Ruling overview

On June 3, 2014, the DOE published its final rule on prescribed performance-based standards for WICFs, which specifically apply to the condensing units and unit coolers used in these systems. Then, on July 10, 2017, the DOE issued an update to the ruling and released its minimum efficiency test procedures, which they termed the annual walk-in efficiency factor (AWEF).

AWEF is a metric created by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) designed to help manufacturers validate compliance. As defined by the AHRI 1250-2009 standard, AWEF minimum efficiency requirements for dedicated condensing units vary per capacity and application (e.g., indoor, outdoor).

Although the compliance date for medium-temperature, dedicated condensing system applications has been in place since 2017, the DOE has established the following enforcement dates for 2020:

  • 1: for medium-temperature WICF applications
  • July 10: for low-temperature WICF applications

Scope and definitions

The scope of the ruling pertains to enclosed WICFs that can be walked into and have a total chilled storage area of less than 3,000 square feet. In addition, the ruling applies only to those condensing units and unit coolers designed to provide one refrigerated load. Products designed and marketed exclusively for medical, scientific or research purposes are excluded from this ruling.

According to the DOE ruling, 32 °F is the point of differentiation between walk-in coolers and freezers. A walk-in cooler is defined as an enclosed storage space refrigerated to temperatures above 32 °F. A walk-in freezer is defined as an enclosed storage space refrigerated to temperatures at or below 32 °F.

The DOE WICF ruling applies to both new and retrofit refrigeration systems, including:

  • Condensing units that are assembled to construct a new WICF
  • Condensing units that are used to replace an existing, previously installed WICF component (retrofit)
  • Condensing units used within packaged systems

Important note: While this does mean that condensing units manufactured after the ruling’s enforcement dates must comply, it does not exclude wholesalers and contractors from using and stocking condensing units that were manufactured before the DOE enforcement dates.

Industry impacts

With the DOE enforcement dates quickly approaching, stakeholders throughout the commercial refrigeration industry need to understand the ruling’s potential impacts on their businesses. Of course, this starts with equipment manufacturers that must not only manufacture compliant products, but also demonstrate certification and compliance through the following: registration with the DOE’s Compliance Certification Management System (CCMS) database; proper disclosure in marketing materials; and permanent nameplate marking.

Impacts to other key stakeholders include:

  • Wholesalers — must be prepared for changing inventories and begin carrying only AWEF-compliant products if they are manufactured after the 2020 enforcement date
  • Contractors — must understand that if they replace a condensing unit with one manufactured after the DOE enforcement date, it must be an AWEF-compliant unit
  • Design consultantsmust be well-versed in the regulatory impacts to advise end users in the selection of energy-compliant, sustainable systems
  • End usersneed to consider selecting future-proof equipment that aligns with their long-term refrigeration strategies

Regardless of your specific role, Emerson offers additional training, resources and expertise to help you prepare for compliance and understand the impacts of the DOE’s WICF ruling. For more information, please view the webinar archive or download our DOE WICF ruling FAQ document.

 

Regulatory Uncertainty Impacts Refrigerant Decisions

Emerson Commercial & Residential Solutions

I was recently asked to contribute to an ACHR The NEWS article about the uncertainty surrounding the dynamic regulations governing the use of refrigerants. The article provided perspectives from several industry stakeholders, and I was happy to discuss Emerson’s views on the short- and long-term implications of the situation. Read a summary of the article below and view it here in its entirety.

For the last two years, the commercial refrigeration industry has been in a period of uncertainty regarding the regulations that govern the use of hydrofluorocarbon (HFC) refrigerants with high global warming potential (GWP). Since the U.S. DC Court of Appeals ruled that the Environmental Protection Agency (EPA) did not have the authority to phase down HFCs, the EPA’s role in the national HFC phase-down has been unclear.

R-22 phase-out is still in effect

For the time being, the EPA’s authority covers only the transition from ozone-depleting substances, such as the chlorofluorocarbon (CFC) R-22. So, even though the HFC rules have been vacated, the EPA still has the authority to phase out R-22, which is scheduled to take place on Jan. 1, 2020.

While there’s plenty of discussion about the fate of HFCs, it would be unwise to presume that the 2020 R-22 phase-out won’t have significant impacts. In fact, it may surprise some to learn that there are still many operators with older refrigeration systems currently charged with R-22. But after Jan. 1, they must either retrofit their systems with lower-GWP refrigerants or continue to recover and reuse R-22 until their supplies run out — with the understanding that the latter choice is not a permanent solution.

HFC phase-down continues in California and other states

The absence of a federal mandate to phase down common HFCs is not deterring California from taking its own steps. Per a recent ruling by the California Air Resources Board (CARB), R-404A and R-507A are no longer allowable in many new commercial refrigeration applications.

California’s regulatory stance is a reminder that a retailer’s geographic location is an important factor in the development of their refrigerant strategy. While California is currently taking the lead on U.S. HFC reductions, there are currently

As retailers evaluate their future refrigerant options, state-specific environmental regulations will factor prominently in their decision processes. For example, operators in California are well aware of the efforts to phase down HFCs and most likely have alternative refrigerant plans in place. These operators are either planning for retrofits or trialing new alternative refrigerant architectures.

Strategies for moving forward

Fortunately for operators, component and equipment manufacturers have continued developing solutions that feature a wide range of lower-GWP refrigerant alternatives. These solutions are helping retailers align their sustainability objectives with their refrigeration architectures, and include the following strategies:

  • Retrofit using lower-GWP HFOs — Moving from R-404A to R-448A or R-449A may require adding compressor cooling and other relatively minor system changes but can help operators preserve their existing system investments. Deploying energy optimization best practices will also help them reduce indirect emissions, which lessens their overall carbon footprint.
  • Transition to a new and/or natural refrigerant system — Natural architectures offer maximum carbon footprint reductions and are considered by many as the only true future-proof solutions available today. These systems can be installed in new locations or in parallel with an existing system, allowing the retailer to slowly transition to the natural solution.

Emerson is continuing to develop a variety of alternative refrigerant solutions designed to help operators and equipment manufacturers reduce their carbon footprints. Regardless of the regulations in your specific region, we’re here to support the commercial refrigeration supply chain as it transitions to lower-GWP refrigerant alternatives.

[New E360 Webinar] Preparing for DOE Compliance on Walk-In Coolers and Freezers

In 2020, the Department of Energy (DOE) will begin enforcing its new energy-efficiency standards on walk-in coolers and freezers (WICF). With the compliance deadline now on the horizon, the commercial refrigeration supply chain is taking a closer look at the ruling and preparing for its impacts. Our next E360 Webinar, on Thursday, Sept. 26 at 2 p.m. EDT/11 a.m. PDT, will shed light on the details of this rulemaking.

Improving the energy efficiency of refrigeration equipment is a goal shared by most stakeholders in the commercial refrigeration supply chain. But when specific energy reductions are mandated by DOE regulations on a commonly used class of equipment, then these goals take on a much greater sense of urgency. The DOE’s 2020 WICF mandate is no exception.

Generally speaking, the ruling will require 20–40 percent energy reductions in WICFs smaller than 3,000 square feet. But, like many regulations of this kind, when you start digging into the details, you’ll find that they’re complicated and often difficult to interpret.

In our next E360 Webinar, I’ll provide a detailed overview of the DOE’s WICF ruling and discuss how it can impact you — regardless of whether you’re an equipment manufacturer, contractor, end user, design consultant or wholesaler. So, if you’re unsure about how to prepare for compliance or just curious how the ruling may impact you, then be sure to join me on Thursday, Sept. 26 at 2 p.m. EDT/11 a.m. PDT for this informative webinar. Attendees will learn:

  • The full scope of the WICF rulemaking
  • Definitions of key terms, concepts and language used
  • Final enforcement dates per equipment category
  • Examples of WICF system configurations
  • Required efficiency levels per the Annual Walk-in Efficiency Factor (AWEF) metric
  • Impacts to various stakeholders throughout the supply chain
  • How to verify and ensure compliance

As with all E360 Webinars, we will allocate time after the presentation for a question and answer session. To make sure we’re able to address your specific questions, this session will be supported by additional Emerson experts on the DOE WICF regulation, including: Roxanne Scott, senior lead project engineer; and Brian Buynacek, senior consultant. So, register now for this informative webinar and let us help you prepare for the DOE WICF compliance deadline.

 

Revisiting Food Safety Best Practices

To raise awareness about the prevention of food poisoning, the Centers for Disease Control (CDC) have designated September as National Food Safety Education Month. Whether you’re a consumer, provider, processor, distributor, restaurant, supermarket or refrigerated equipment manufacturer, it is important to be aware of issues related to food safety so we can all help to minimize risks of potential contamination throughout the food supply chain.

Revisiting Food Safety Best Practices

What’s at stake?
According to CDC estimates, one out of every six people (48 million) gets sick, 128,000 people per year are hospitalized, and 3,000 per year die from eating contaminated food each year in the United States. Although this could potentially happen to anyone, those whom are especially vulnerable include: children 5 and under, adults 65 and older, those with compromised immune systems, and pregnant women.

But the potential costs of foodborne illness outbreaks go far beyond their tolls on human health. Researchers have found that restaurants have incurred  costs of up to $2.5 million for a single outbreak of foodborne illness. This may be in addition to brand reputation impact that are more difficult to calculate.  Studies have shown that 44 percent of consumers will avoid a brand for a few months after an outbreak, while 20 percent have reported in surveys that they never intend to make a return visit or purchase anything from that brand again.

How to protect yourself
Foodborne illnesses occur when food becomes contaminated with harmful bacteria, parasites, viruses or toxins. Common types of bacteria associated with raw or undercooked poultry include campylobacter and salmonella. Fruits and vegetables (such as leafy greens) can become contaminated with E. coli, salmonella and listeria due to several factors: from unclean water and runoff at a farm; contaminated processing equipment; and from poor hygiene during handling and preparation.

It is critically important for anyone preparing food to maintain proper holding temperatures as part of ensuring food safety.  This also often maximizes food quality and shelf life.

So, when it comes to preparing your own food, the CDC recommends four simple steps to protect yourself and your family:

  • Clean — Wash hands, utensils and cooking surfaces.
  • Separate — Keep raw meat, poultry, seafood and eggs separate from cooked food and fresh produce.
  • Cook — Use a food thermometer to make sure foods are cooked to an internal temperature sufficient to kill potential germs.
  • Chill — Refrigerate perishable foods and leftovers within two hours; chill within one hour if ambient temperatures are above 90 °F.

But what about the food we buy at restaurants, food trucks or supermarkets? One-third of Americans eat fast food every day, and more than 60 percent have dinner at a restaurant at least once a week. On its way to those points of sale, food passes through multiple hands and stakeholders throughout the supply chain, each with a responsibility to help ensure food safety and quality. Here are a few more common sense tips to consider when dining out or buying from your local grocer.

  • Shop smart — Choose tidy, well-kept establishments with clean tables, aisles and floors. Some cities/states require facilities to post their cleanliness ratings. If you live in one of those regions, ask for the location of that
  • Ask questions — Inquire about how items on the menu are prepared, how grocery items are stored, and any other pertinent information about the source.
  • Inspect your selections — Look for holes, tears or openings in food packages. Frozen foods should be solid throughout with no signs of thawing. Refrigerated foods should feel cold.

Ensuring safety in the food supply chain
While most of these tips can also apply to the food supply chain, ensuring adherence to them from farm to fork is an even more complex challenge for producers, processors, distributors and others in the food supply chain. By the time food reaches consumers, there are potentially any number of handling and temperature excursions that could have taken place. There are also an ever-increasing number of food safety regulations and documentation requirements that stakeholders must comply with.

Today, Emerson is helping leading food supply chain providers, processors, warehouses, distributors and retailers ensure food safety and protect their brand reputations. Building upon our foundation of refrigeration expertise, we’re providing solutions to help operators at nearly every point of this process to help form a comprehensive, unbroken cold chain. From connected, communicating devices and enterprise management software to temperature loggers, trackers and probing devices, we’re helping our customers achieve cold chain temperature certainty and food safety verification throughout its journey to consumers.
