Case study involving demand response for Cirelli Foods, Inc.

  Supermarkets and grocery stores have steady and
long energy consumption patterns. While consumers
shop morning through evening every day, the systems
within these stores operate with even longer hours.
Refrigeration systems cool stored food or drink products
in display, case and walk in coolers, constantly compensating
against rooftop based HVAC for the general store area and
outside air from storefront entrances and loading dock areas.
Overhead, task, and case general lighting systems illuminate
the front and back areas of the store while ovens, fryers,
stoves and kettles contribute heat into refrigerated food
preparation areas.

With these long operating hours, dynamic levels of heating,
cooling and occupancy, Groom Energy's team can always
identify energy saving upgrades which save money,
without impacting the customer experience.
