Highland Park Market Selects JouleSmart to Achieve Operational, Energy Efficiency, and Environmental Goals


To, at minimal cost, reduce Highland's carbon footprint and operational costs while enhancing lighting quality of four grocery stores.

Highland Park Market, a family-owned-and-operated chain of grocery stores in Central Connecticut with a strong commitment to community, sought to:

  • Remain at the forefront of innovation
  • Reduce greenhouse gas emissions
  • Cut operational and energy costs
  • Differentiate itself from the competition
  • Smarten operational and energy management within four 20,000-sq.ft. facilities.
Highland Park Markets are first truly smart grocery stores in Connecticut. They use innovative financing, energy savings performance insurance, wireless communications, cloud-based controls, and are connected to the Smart Grid to interact with the utility in real time.

Modernize and upgrade lighting, achieve sustainability objectives, and improve operational efficiency while minimizing day-to-day business disruptionwith no cash outlay.

JouleSmart designed a turnkey retrofit, including sensors and controls. Wiring was done during business hours; fixtures were replaced overnight. Performance-based financing provided Highland an appealing zero initial-cost solution. The project consisted of:

  • The JouleSmart Buildings system to aggregate energy consumption data, reveal usage patterns, and minimize fuel consumption
  • Sensors to monitor equipment, room, freezer, and cooler temperatures; send alerts, switch off lights, or adjust temperature to reduce food spoilage and energy consumption
  • Fluorescent lights replaced with adjustable LEDs, allowing Highland to use lighting appropriately in different parts of the stores to highlight displays, draw in customers, and create inviting environments
  • Controllers to improve humidity control, reduce energy use, and extend equipment life
  • A building management system to monitor and adjust via wireless and cellular networks


Performance projections show a $500,000 decline in electricity costs, a 900 ton reduction in carbon dioxide emissions, and a $1 million increase in value of the Highland marketsall to be accomplished with no capital spent by Highland on equipment upgrades.

Joule provided full project investment. Using our energy market expertise, we secured rebates for Highland that lowered equipment and labor costs by nearly 50%, shortening the payback period and contract term. Energy costs are expected to decline due to lower peak demand, reduced by the upgraded equipment. We also negotiated for Highland's participation in direct response programs, providing access to benefits for which Highland would ordinarily not be large enough to qualif
