Chemistry Building

Retro-Commissioning

Albany, NY


Project Highlights

In-depth Retro-Commissioning study of SUNY Albany's chemistry building to determine condition of existing building HVAC system, and to identify system upgrade and energy conservation measures and strategies. 


M/E Role

The following building retro-commissioning services were provided:
Retro-Commissioning of building HVAC and laboratory environmental systems.
Determination of building ventilation systems capability to serve additional laboratory spaces.
Recommendation of strategies to be implemented to increase building supply air/exhaust air capabilities.
Identification/recommendations of feasible HVAC related energy conservation strategies or measures that could be considered to reduce overall building energy consumption.
Building testing included the following:
Air flow measurement at air handling units and exhaust/return fans.
Inlet and discharge air temperatures and pressures.
RPM and motor amperage for each fan and HVAC related pump motor.
Water flow measurements (supply/return).
Verify temperature control set points at the BMS.
Air flow measurement at each terminal unit (dual-duct box).
Supply/exhaust/return air flow measurement at each room.
Verify sensor set points and actual space temperatures.
Test all operational dampers.
Fume Hood/Air Valve Testing and Verification was conducted.
Verification and testing of all fume hood controllers.
Deficiencies were noted at the time of identification.
Field testing of laboratory air flows were documented for exhaust air, fume hood exhaust and make-up/supply air.
Room pressurization relationships were tested and documented for all laboratory spaces relative to the adjacent corridors.
All space diffusers, grilles, registers were tested to determine if any significant air leakage exists between terminal boxes and room delivery points.
The following measures were analyzed:
Conversion of dual duct systems to variable air volume.
Installation of premium efficiency motors and variable frequency drives on air handling unit fans.
Direct Digital Control system upgrade.
Fume hood replacement or retrofit to lower flow/variable volume or enhanced control strategies.
Alternative building exhaust approaches.
Possible heat recovery opportunities.
