Delivering the “most energy efficient hospital in the United States”

The significantly aggressive energy target, coupled with a tight timeline created both a challenge and even bigger opportunity. Mazzetti (at the time CDi Engineers) responded by making early decisions, conducting energy modeling, using VAV and Heat Recovery Chillers, integrating design and construction, and expediting equipment procurement. We delivered using Integrated Project Delivery Method (IPD)

Scope

Mechanical engineering services for a new five-story, 175 bed, 350,000sf acute-care hospital and attached six-story 200,000sf  Medical Office Building.

EUI Scope

The client’s original EUI target was 150. The estimated EUI for the hospital portion of the project was 135 KBTU/SF-YR. The actual utility data results for the first ten months of operation matched the estimates. (In comparison, similar hospitals in the Pacific Northwest region have an average energy use intensity of 250 KBTUs per square foot.)

Mazzetti worked with Puget Sound Energy (utilities) to obtain substantial financial rebates for the designed energy-savings features. Rated one of the “Top Ten” most energy efficient hospitals in the U.S. (51% less than the average U.S. hospital after 14 months in operation).
