Retro-commissioning

Retro-commissioning is the best way to improve your current HVAC system’s efficiency. It will resolve issues that happened during design, installation, and lifetime use.

Retro-commissioning resolves these issues:

Fixes poorly working belts, valves, thermostats, and sensors.

Eliminates simultaneous heating and cooling.

Optimizes air balancing systems.

Resolves variable frequency drives that operate at high speeds or the same speed with a variable load.

Equipment and lighting components will only be on when needed.

Retro-commissioning reduces energy costs (by $0.13-$2 per square foot!), improves indoor air quality (IAQ), and creates a more comfortable environment for occupants.

2. Mind the gap - gaps in the building, that is.

Those small gaps in windows, doors, walls, and floorboards are a magnet for heating and air conditioning. If those gaps are in your building, it’s time to seal them.

Weather strip windows and doors to keep the cold out and heat in.

Seal cracks in walls and flooring.

Get a building energy audit with infrared imaging to pinpoint where any heat escapes.

3. Add building automation systems (BAS)

A good BAS will reduce energy usage on multiple levels.

Intelligent adjustments will learn the occupancy of the building and make changes accordingly. If no one is in the building, the HVAC will adjust to the “away temperatures.”

Studies have shown that building automation systems save between 5% and 30% on utility bills. The BAS will intelligently schedule heating, air conditioning, lights, and more to only be on when occupants are in the building.
