Marion County Health Clinic – Salem, Oregon
Mechanical System Design / Deep Energy Retrofit
Marion County Health Clinic is a 50,000 sq.ft. architecturally unique county health clinic. Originally designed and constructed in 1974, the building’s envelope, lighting, and mechanical system performance had deteriorated significantly. In 2015, Mike Hatten of SOLARC undertook an assessment of the mechanical system deficiencies that ultimately led to the design and construction of a major system renovation, as part of an overall building renewal project.Components that were completely modernized and upgraded included air distribution, heating, pumping, and controls. Hatten designed the upgrade in which the mechanical system was downsized to respond to complete replacement of original single pane glass with modern high performance double paned glazing, and the upgrade of interior lighting to LED. Hatten also led a parallel energy analysis effort that identified overall energy savings potential and qualified the project for a sizable financial incentive from the Energy Trust of Oregon.
Overall, the building’s comfort has markedly improved in both heating and cooling seasons. Building envelope no longer experiences excessive air infiltration. Air distribution is significantly improved in all spaces. Building maintenance and operations are also much easier due to replacement of failed components and use of the new graphics interface on the HVAC controls. Key project performance parameters are listed below.
