The Department of Energy announced the Advanced Roof-top Unit Campaign (ARC) results of building owners that are replacing or retrofitting the aging heating and cooling technologies installed on roofs of many US commercial buildings. Since 2013, ARC has spurred over 190 public and private sector organizations to replace or retrofit 40,000 high-efficiency commercial building roof-top units, saving 4 trillion BTUs of energy or $37 million.
The following organizations were recognized for achieving significant energy savings by replacing or retrofitting roof-top units (RTUs):
- adidas for its innovative RTU management approach and updates to the equipment replacement strategy from replace-upon-failure to proactive replacement;
- Target gained the largest efficiency improvement from a single building RTU replacement project, as well as the largest efficiency gain for a multi-building RTU replacement project;
- US Citizenship and Immigration Services, US General Services Administration, Pizzagalli Properties, and Elman Investors installed 66 RTUs, the most installed on one building;
- US Navy, Joint Base Pearl Harbor-Hickam retrofitted 30 RTUs with advanced controls;
- Walmart Stores completed over 10,000 high-efficiency RTU installations in new and existing stores; and
- Whole Foods Market retrofitted 107 RTUs with advanced controls, resulting in an estimated 836,535 kWh of energy savings.
