Säzän Group provided full mechanical design services on this work-order project to renovate Fort Lewis’ historic 20,000 SF chapel and annex. The main priority of the renovation was to retain the chapel’s historic character while making it more functional. Säzän added air conditioning to the chapel and upgraded the heating system to increase occupant comfort and energy efficiency.
The design incorporated a highly-efficient horizontal geothermal heat pump exchange system. Approximately 24,000 linear feet of horizontal polyethylene loops were buried six-feet deep in the lawn adjacent to the chapel. The anticipated lifespan of the system is 30 years, with energy savings estimated at 30% over the chapel’s heating system alone.
“I wanted to extend to you the kudos that your team received from the Public Works Historic representatives. They said that this is the first time that they have sent a design document to the State Historic Preservation Office for approval and had it approved with no comments! The SHPO said that it was very well done. Great job!”
