MEP Associates, LLC (MEP) recommended the use of a geothermal HVAC system, and solar panel as feasible sources of alternative energy. The use of solar hydronic heating panels were used to supplement the geothermal HVAC system during the heating season.

The 8,240 SF Office and Visitor Center at Morris Wetland Management District in Minnesota is a model of sustainable design excellence. The new facility combines interior daylighting, low-e glazed windows, and energy-efficient lighting to improve comfort and performance. A 23-ton ground source heat pump works with an enthalpy wheel and energy recovery ventilating units to maintain indoor air quality while improving energy performance by 30 percent.

The facility's water-efficient fixtures, native landscaping, and natural storm water management system saves water. A net-metered 20 kW solar photovoltaic array provides 35.9 MWH of renewable power, which offsets 25 metric tons of greenhouse gases annually.

Sustainable features include a cool roof; HardiePlank siding, high-recycled content ceiling tile, decks, railings, and rubber mulch landscaping.

Commissioning Services
MEP provided Fundamental Commissioning Services for the new mechanical systems in the existing building. The systems included geothermal water to air heat pumps, energy recovery unit air distribution system, and electrical systems including photovoltaic panels.
