Value Delivered
ECM performed a turnkey retrofit of 39 chemical fume hoods at the Chemistry and Life Science Building at Colorado State University Pueblo. To convert three labs from constant air volume (CAV) to variable air volume (VAV), we replaced each unit’s controls with new, cutting-edge TEL controls and automatic sashes.
The project resulted in annual energy savings of 379,498 kilowatts and 59,277 therms, helping reduce costs by $66,403 annually with a simple payback of 6.4 years.
Client Objectives
The building’s airflow systems were not efficient, and the lab spaces were loud, uncomfortable, and very expensive to ventilate and condition. In addition, safety was a concern as the older equipment lacked basic containment alarms. The university wanted to correct these issues, to help ensure safety and efficient operation.
Solutions
ECM provided the following services:
- Added VAV controls to CAV fume hoods
- Replaced existing VAV fume hood controls
- Replaced fast acting exhaust valve actuators, mono blade dampers, and room pressure controllers
- Installed new fresh air bleed dampers and controllers
- Installed automatic sash closers
- Sealed building envelope of lab room to improve pressure control
- Re-balanced the exhaust fans and static pressure control to decrease the noise level
- Certified fume hood safety and energy efficiency
Client Background
