As we\u2019re all well aware of by now, the Department of Energy<\/a> (DOE) and Natural Resources Canada<\/a> (NRCAN) implemented new energy efficiency rules, regularly referred to as \u201cAWEF.\u201d Since coming into effect on January 1, 2020 we have received a number of frequently asked questions<\/a> surrounding these new regulations, especially questions in regard to compliance.<\/p>\n

Staying true to Our Continued Commitment to the Refrigeration Professional<\/a>, we are here to answer any and all of your AWEF questions.<\/p>\n

Achieving Compliance Through AWEF Standards<\/strong><\/p>\n

To evaluate the energy efficiency of a complete walk-in cooler and freezer (WICF) system, the DOE uses a metric called the Annual Walk-In Energy Factor<\/em> (AWEF) created by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI)<\/a>.<\/p>\n

According to AHRI, this calculation is based on \u201ca ratio of the total heat, not including the heat generated by the operation of refrigeration systems, removed, in Btu, from a walk-in box during a one-year period of usage for refrigeration to the total energy input of refrigeration systems, in watt-hours, during the same period.\u201d<\/p>\n

As mentioned in previous articles<\/a>, these regulations apply to WICFs smaller than 3,000 square feet. This includes a number of WICF product types that must meet or exceed the minimum AWEF ratings based on capacity and application.<\/p>\n

We know this is a lot to keep track of which is why we have put together the following table detailing the minimum AWEF rating per product type.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

Who\u2019s Responsible for Making Sure Products and Equipment Are Compliant?<\/strong><\/p>\n

It is the responsibility of the manufacturer to certify its equipment to be manufactured and sold as compliant. It is the responsibility of those assembling\/installing the system to use certified equipment for retrofitting existing jobs and\/or for new installations. This includes:<\/p>\n
