HTS representing Aircuity: Northwestern University

Airside energy efficiency plays a key role in strategic vision for campus facilities.

Northwestern University’s, first Aircuity installation came in 2010 to monitor the integrity of a heat recovery system in a lab building. Today the leading research university has implemented Aircuity in total of 8 buildings across two campuses.

The Arthur and Gladys Pancoe Life Sciences Pavilion was one of the most recent buildings to be retrofitted with Aircuity. The University was looking to upgrade the control platform and hoped to fund it by reducing energy consumption. A collaboration between Facilities Management and the Office for Research Safety was formed to ensure the project was a success.

BUILDING PERFORMANCE EVALUATION

Based on the results of past projects, Aircuity Channel Partner, HTS Chicago, worked with Northwestern to plan the infrastructure upgrade and retrofit of all lab floor spaces of the Pancoe building. Prior to the installation, labs were running near 9 ACH (air changes per hour). At the outset of the project the proposed air change rates were 4 ACH during occupied and unoccupied times, consistent with previous Aircuity system implementations. Instead Northwestern’s James McKinney, Director of Facilities Management and Operations and Markus Schaufele Director of Standards, Compliance and Emergency Planning agreed to test the possibility of safely lowering the air change rates to 2 ACH during unoccupied times. The plan was to closely monitor the performance and occupant behavior data for select labs within Cook Hall where a system was already installed. Occupancy was determined by ceiling mounted motion detectors wired into the lab control system.
