The Stockbridge-Munsee Health and Wellness Center, which may initially seem an unassuming facility to new visitors, carries out a critical mission and holds an important place in its community. Located in the rural town of Bowler, Wis., on the southwestern edge of the Menominee Indian Reservation, the more than 50-year-old clinic is a civic asset for the Stockbridge-Munsee Band of Mohican Indians.
The program began in the early 1970s as Volunteer Inter-Tribal Medicine, comprising a group of volunteer physicians who provided care and health screenings. The clinic started as a retrofitted mobile home and has since grown into a community wellness organization operated by and for the tribe. The facility includes a pharmacy, dental care, a radiology unit and countless other comprehensive community health services.
The existing clinic is a 30,170-square-foot building that opened in 2000. Served by an HVAC system nearing the end of its life, the existing infrastructure featured a conventional water-source heat pump for heating and cooling, an evaporative cooler, propane boilers and a propane-heated ventilation system.
The evaporative cooler, which uses water as its working fluid, recirculates domestic water in the basin and sprays it over closed-loop coils of the hydronic cooling system to increase cooling capacity. To prevent chemical growth, systems like this one require extensive chemical treatment, and although the client had well-trained facilities personnel, it was decided that going in a new direction would be a more efficient and sustainable practice.
The Health and Wellness Center sought measures to achieve energy sovereignty for its organization. Its goal was to be far less reliant on propane to heat the facility and remove the need for regular chemical maintenance. To achieve this would require an entirely new HVAC system — one that could moderate the usage of natural resources and embody the community’s core beliefs.
