HVAC systems are often the largest energy consuming system in a commercial or industrial building. Based on your building type, operating characteristics, and climate zone, energy spend is likely some combination of fuel for boilers, electricity for RTUs, chillers, air handling units, split systems, and ventilation.

Our engineers will analyze your facilities, including original designs, blueprints, changes since original construction, and building envelope. We also will compare against current controls design and implementation to perform HVAC opportunity assessments. Our goal is to implement the most cost-effective solution for your operation. Our recommended retrofit and control solutions are designed to achieve compelling energy savings.

Rather than equipment replacements, we focus on controls and modifications to improve efficiency while delivering a return on investment.


Chillers, Rooftop Units, and Air Conditioning Systems

Comfort cooling is a requirement.  Avoiding a “constant on” mentality by matching load with occupants and time of use improves occupant comfort and reduces the cooling load. (Click here for Case Study – RTUs)


Upgrading older conventional boilers with high-efficiency condensing boilers can be a very cost-effective way to reduce fuel consumption and lower maintenance costs, especially where utility incentive programs are available. Even newer boilers can be retrofitted for energy performance improvements with high-efficiency burners coupled with digital controls.

Ventilation Systems

Fan motors inside HVAC systems consume significant energy, but even modest changes to their operations can significantly impact energy consumption, maintenance, and overall equipment life.

Variable Frequency Drives (VFDs)

Traditional systems have a full on control.  VFDs are customized controls that manage the speed of motors throughout the HVAC system to match the partial load requirements of an operation. Ventilation and dust collection systems, circulating pumps, compressors and cooling towers are traditionally configured with motors running continuously at full speed, which presents an opportunity to upgrade to VFDs and reap significant cost savings.

Our team’s detailed and data-driven approach analyzes the current use of these system components, determines where energy consumption can be reduced, and develops a financing plan, using utility incentives (when available), to deploy a range of HVAC upgrades.  (Click here for Case Study – VFDs)
