Energy Regulations

It has been a little more than a week since my last posting where I talked about Greenchill and the need to control leaks from systems. The other major driver of a system’s impact on the environment is energy. We at Emerson are always tracking the latest energy efficiency regulations, and 2012 brought several changes for commercial refrigeration equipment including reach-ins, ice machines, walk-ins, supermarket display cases and other stationary commercial refrigeration equipment.

For example, the allowable federal minimum energy efficiency level is actually the same as the voluntary standards set by ENERGY STAR in 2001 for reach-in refrigerators and freezers. The 2010 ENERGY STAR 2.0 standards were baselined to capture the top 25 percent of energy performers. Since 2011 the EPA requires third party lab testing for the ENERGY STAR program. The new LEED for Retail rating system includes equations to calculate levels for prescriptive path LEED efficiency, based on the previous CEE Tier 2 and California Investor Owned Utilities incentive program (CAIOU).

Energy and environmental standards are constantly changing which presents a challenge for refrigeration equipment manufacturers. I would like you all to read more about these and other useful information by clicking on this link below for the Emerson white paper “Status of energy regulations for commercial refrigeration equipment”:

GreenChill for Food Retailers

For those of you who are unaware, the U.S. Environmental Protection Agency has a voluntary partnership with food retailers to reduce refrigerant emissions and decrease their impact on the ozone layer and climate change called GreenChill. I encourage you to visit their website ( It is a wonderful resource for more than just supermarket retailers, packed with considerable information, including: how to become a GreenChill partner; a complete library of webinars and events; and a variety of reports, guidelines and tools that will assist your company with its stewardship efforts.

 Are you a member of GreenChill? I’d be interested in learning your opinions of this group.

 Are there other similar groups or organizations you find helpful and informative that you’d like to share with us? We look forward to hearing from you.

Welcome to Climate Conversations!

Welcome to Climate Conversations, which we hope will be a valued communications initiative on topics & developments relevant to the HVAC&R industry. The name is broad but says it all.

Climate — probably the first thought that the word brings to mind is environmental, and frankly we are all stewards of our environment at some level. Global warming concerns have driven different parts of the industry to set various sustainability goals and evaluate the options to meet them. So environment is definitely a part of the conversation.  So is refrigerants.  And technology. And best practices.  We’ll cover a range of comfort, freezing & cooling topics here.

Conversations — definitionally a two-way discussion.  An informal interchange of thoughts.  We hope you feel the freedom to “converse” by adding your contribution.

Climate Conversations will focus on topics and technologies that improve human comfort, safeguard food and protect the environment – our long-standing motto.

We will provide an avenue for both the industry experts at Emerson Climate, external authors & contributors, and the readers of this blog to offer varying opinions and new information. If all goes well, Climate Conversations will become as much your blog as ours.

So let’s get started!
