Today the U.S. Department of Energy recognized Southern California Edison for their leadership in replacing and upgrading roof-top units as part of the Better Buildings Alliance’s Advanced Roof Top Unit Campaign (ARC). Southern California Edison joins five other leading organizations that in a single year have saved an estimated 1 trillion British Thermal Units (BTUs) or more than $11 million on utility costs with efficient RTU replacements, retrofits, and quality management and operations. Since 2013, 250 ARC partners have upgraded 59,500 RTUs for a total energy savings of 10 trillion BTUs or $93 million in cost savings.
A building’s cooling and ventilating energy consumption can be reduced between 20-50 percent when aging equipment is replaced with high-efficiency units or retrofitted with advanced controls. In fact, a building owner can save as much as $3,700 per RTU – equivalent to $6.7 billion and 670 trillion Btus annually.
The following organizations are being recognized this year for their innovative RTU management approaches that led to significant energy savings in commercial buildings:
- Arby’s Restaurant Group, Inc. made 238 high-efficiency RTU replacements across 900 stores, resulting in an estimated savings of 1.4 million kWh, worth $140,000 annually. It’s the most innovative RTU management approach by a participating partner;
- Giant Tiger Stores Limited had the largest efficiency gain for a single building RTU replacement project, a 63 percent installed efficiency gain with 41 percent (30 Tons) capacity reduction;
- Southern California Edison upgraded 4,679 high-efficiency RTUs and 400 advanced RTU control retrofits, resulting in an estimated savings of 31 million kWh, worth $4.7 million annually;
- Target Corporation upgraded 532 RTUs, resulting in an estimated savings of 10 million KW annually. This is the most innovative, comprehensive RTU operations approach by a partner for enabling large reductions in installed capacity and includes centralized and optimized control of RTUs;
- Walmart Stores, Inc. upgraded 5,919 RTUs – the highest number of high-efficiency RTU installations – resulting in an estimated savings of 50 million kWh, worth $5 million annually; and
- Whole Foods Market retrofitted 839 advanced control retrofits – the highest number of advanced RTU control retrofits – resulting in an estimated savings of 7.6 million kWh, worth $747,000 annually. Whole Foods had the highest number of RTU installations that meet and exceed the RTU challenge specification, 12 highest efficiency RTUs, with an estimated savings of 120,000 kWh, worth $12,000 annually.
About the Better Buildings Alliance’ Advanced Roof-top Unit Campaign
Through Better Buildings Alliance technology campaigns, public and private sector organizations across the country working together to share and replicate positive gains in energy efficiency and catalyze change and investment in energy efficiency. The Advanced Roof-top Unit Campaign provides building owners and operators with access to information and expertise to lower facility operating costs while maintaining or improving building occupant comfort. Through Better Buildings, the Energy Department is working to make commercial, public, industrial, and residential buildings 20 percent more energy efficient over the next decade. This increased efficiency would save billions of dollars on energy bills, reduce greenhouse gas emissions, and create thousands of jobs.
