We leverage a wide variety of energy saving measures, including demand management systems, building metering at the circuit breaker level, building control systems, energy audits, LED and LEP lighting, window coatings, insulation, variable speed motors, solar thermal, solar air conditioning, and HVAC upgrades, to reduce energy usage for schools, universities, governments, hospitals, grocery stores, cold storage facilities, airports, ports, corporations, and farms. These projects typically reduce customer energy usage ~20%, have payback periods under 5 years, and are financed based on savings. Electric rate inflation is a growing problem for many of these organizations, particularly those in rural or economically depressed areas with limited or declining tax revenues and who are served by a utilities excessively dependent on coal.
Typical Energy Efficiency Savings by Building Type
Most Effective Energy Saving Measures
Lighting accounts for up to 25% of commercial building electricity usage and is the easiest energy efficiency measure to implement with 30%+ savings and payback periods under three years
Real-time metering at the circuit breaker level provides the data necessary to achieve fast operational savings, identifies opportunities for energy saving measures, and provides verification that savings are real while providing 4-12 month payback periods
Solar Heating & Cooling
Solar thermal systems offer faster paybacks than PV for water heating, radiant floor heating, and powering the absorption chillers that are commonly used for air conditioning, cold storage, and refrigeration in large commercial buildings with some cold storage applications having payback periods measured in months
LED Lights · HVAC · Chillers · Controls · Boilers · Refrigeration · and More
Lack of budget is the number one reason building equipment purchases like lights, chillers, and controls don’t get approved.
Building controls serve as the brain of a building and allow the implementation of demand response, demand charge management, time shifting of generation and loads, frequency regulation, voltage regulation, and smart curtailment of devices
Energy storage is increasingly economic for commercial projects with high demand charges, high utility time-of-use rate schedules, and/or mission critical infrastructure that must remain operational when the electric grid fails
Insulation, weather sealing, and window coatings reduce heating costs in winter and cooling costs in summer while delivering 2-5 year payback periods. Most other building envelope improvements like windows, roof, or siding replacement is not economic based on energy savings alone.
