Complete Store Energy & Sustainability “Make-over” Project In early 2013, CoolSys, Whole Foods, CLEAResult and SMUD set out to transform an existing store with a variety of newer technologies in order to achieve a 30+ % reduction in energy costs. In addition, using what Whole Foods Tristam Coffin described as a “Holistic Approach”, the team focused on water and chemical use reductions, refrigerant charge and carbon footprint reductions, as well as improvements to store environment for Whole Foods customers and employees. Many measures were employed, including: transformation of the LT R404A system to CO2, replacement of a marginal control system with a new EMS platform with visual graphics, replacement of the existing evaporative condenser with Hybrid condensers, a complete new LED lighting system, upgrade of package HVAC equipment to high efficiency with demand ventilation and DEH capabilities, outside air treatment for building make up…

A leader in the food industry for over 90 years, Spartan Stores operates a chain of more than 100 grocery stores in the state of Michigan. Spartan is unique in that they have grown their chain through acquisition rather than building new stores. That presented some challenges when initiating energy efficiency projects. The equipment and controls Spartan inherited in these acquisitions varied in condition, and, because of this, they knew that their stores were not operating at optimal energy efficiency. Spartan needed a plan to address critical issues first. CoolSys was contracted to help Spartan address this challenge.

As part of an aggressive energy savings campaign, SUPERVALU’s Albertson’s chain decided to invest in an extensive door retrofit program in 100 of its Southern California stores.
