3. Supporting an energy-service performance contractor, McKenney’s
developed and installed several energy conservation measures (ECM)—
including new domestic hot water (DHW), heating hot water (HHW) and
HVAC systems.

4. The Challenge
The facilities had existing steam boiler plants, chillers and HVAC
equipment that had to remain operational during the ECM upgrades.
A plan was needed to tie in the new systems without incurring service
interruptions in high security, limited access work areas.
The Solution
During project development, McKenney’s provided design/assist
services to advance a phasing plan to meet facility requirements
and avoid service interruptions. Temporary services were provided
when facility interruptions were unavoidable. Components for the
DHW, HHW systems and rooftop units for the HVAC systems were
prefabricated—including boiler/pump skids that could be quickly
installed—to minimize the team’s time on premise.

5. The Results
McKenney’s installed the ECMs with minimal downtime and increased
HVAC performance levels while reducing energy costs. Startup,
commissioning and owner training resources led to a clean project
close out.
