The project

WUSM was looking for a DCKV solution as part of a retro-commissioning project at the McDonnell Science building. With the need to retrofit modulating dampers into the existing 5 hoods, ECOAZUR became the perfect control solution for this multi-hood, single exhaust fan design.

 

The Solution

This ECOAZUR system features an optic sensor, temperature sensor, and modulating damper system to ensure that each hood is getting the proper amount of airflow for the individual hood’s cooking operations. The system features cloud-based connectivity as well as building automation BACnet integration. From an estimated 50% new average fan speed, the University is over-achieving on energy savings with a new average fan speed of 44%! The exhaust will now rarely need 100% fan speed for cooking operations.

The Results

Runtime Hours per Day: 10 | Total Controlled CFM: 10,000

Estimated Preliminary Analysis:

Average New Fan Speed: 50%
Electrical Savings: 69,263 kWh / year
Electrical Savings: $5,541 / year
Heating Savings: $2,459 / year
Cooling Savings: $391 / year

Post Installation Analysis:

Average New Fan Speed: 44%

Electrical Savings: 76,541 kWh / year

Electrical Savings: $6,123 / year

Heating Savings: $2,772 / year

Cooling Savings: $441 / year
