A Midwest Health System

PRES conducted a comprehensive energy audit of all facilities to identify the total energy consumption and cost savings potential for viable conservation measures within the Health System’s real estate portfolio. In addition, PRES Energy was asked to identify any existing mechanical / electrical infrastructure that should be considered for scheduled replacement (“deferred maintenance”), or systems that pose a business risk upon failure. Facility Audit Reports were delivered for each facility detailing current conditions, historical energy spend and recommended energy / deferred maintenance projects.

PRES provided management with a prioritized project implementation plan to address all the items contained in the individual Facility Audit Reports; the hospital systems CFO requested this program be phased over a four year period. Working with corporate and individual hospital facility management, PRES developed a schedule of work for a four year implementation program with the goal of executing imminent failure projects and high ROI energy savings projects in the early stages.

PRES provided all engineering, construction management and program coordination for this $15MM program. Existing equipment retro-commissioning and new systems commissioning was also provided by PRES staff to ensure equipment was installed and operating as intended.

Over 70 individual projects were implemented resulting in annual energy cost savings of $2.2 million. Risk-based and code compliance actions were also incorporated in many of the HVAC related projects. Approximately $15 million in capital funded the initiatives over a 4-5 year period; this approach allowed for the energy savings harvested early in the program to generate positive financial results for deferred maintenance projects implemented in subsequent years.
