Supermarkets can obtain new revenue from the thermal energy potential locked inside their stores by connecting with utility demand response programs that offer rebates and with DHC customers who will pay for district heating and cooling. Today, the capabilities of advanced system managers offer opportunities to utilize DHC and smart-grid strategies in the future while operating HVACR equipment and lighting more efficiently now. Supermarkets will also benefit as CO_2 systems become more prevalent due to advances that make them more efficient than HFC refrigerant systems —extending even into warmer southern climates. C0_2 also enhances HVACR system efficiency and creates a greener facility with a significantly smaller carbon footprint.
