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.

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.

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.
