Maryville Nursing Home

Maryville Nursing Home is located in Beaverton and occupies 92,000 square feet. Maryville houses hundreds of assisted living apartments, full service kitchen and laundry facilities, as well as dozens of offices and other amenities. Originally constructed in 1964 minimal upgrades had been made to the original mechanical systems.

American Heating, Inc. designed and installed an energy efficiency retrofit of the boilers, chiller, DHW, and DDC control system. AHI replaced the chilled water plant with a new chiller with condenser heat recovery to the domestic water system. The boiler was upgraded to a fully modulating condensing boiler. New condensing water heaters were installed. The DDC control system was a complete replacement and included converting the two pipe system into a more comfortable multizone two pipe system with dozens of control zones located in the mechanical room.

Due to the 24/7 operation of the facility AHI coordinated a construction and implementation schedule to complete project with no down-time for the owner. The design included minimal intrusion by locating the majority of the components in the central plant.
