Energy Saving Solution — Commercial Building Retrofit
Retrofitting a commercial building's HVAC and lighting controls to cut energy waste without a full system replacement.
Most commercial buildings don't waste energy through equipment failure — they waste it through equipment running when it doesn't need to. A retrofit-focused energy saving solution targets that gap without requiring a full mechanical system replacement.
The Challenge
An existing commercial building was operating with manually scheduled HVAC and lighting, resulting in significant after-hours and low-occupancy energy waste, but a full BMS replacement wasn't justified by the building's remaining equipment lifespan.
The Solution
We implemented an energy saving retrofit centered on occupancy-based HVAC scheduling, sub-metering for consumption visibility by zone, and automated lighting controls tied to occupancy and daylight sensing — layered onto the building's existing mechanical plant rather than replacing it.
The Result
The building's facilities team gained real visibility into where energy was actually being consumed, and automated scheduling eliminated the after-hours waste that manual control had been missing. The retrofit approach delivered meaningful energy savings at a fraction of the cost and disruption of a full system replacement.
