All construction and renovation at Carthage follows green principles.
- New and renovated campus buildings incorporate methods to reduce energy consumption, including day lighting, occupancy sensor lighting controls, and demand-controlled ventilation systems.
- The Campbell Student Union was designed to be 29.8 percent more energy-efficient than the average Wisconsin building. In addition to day-lighting, occupancy sensor lighting controls, demand-controlled ventilation and other Carthage building standards, the student union features a rain garden to manage storm water.
- Construction of The Oaks Residential Village, Carthage’s newest housing option, involved extraordinary measures to protect trees in the area. An arborist was on the original design team, and all contractors had to pass training by the arborist before digging could begin. Fences protected trees and their root zones throughout construction of the buildings, and if a contractor needed to venture into a protected area, an arborist first examined the work to be done.
- The College recycles building materials whenever possible. Eighty-five percent of the former Siedemann Natatorium materials were recycled when the building was renovated to create the Campbell Student Union, including $6,000 worth of aluminum from the former swimming pool.
- There is an active geothermal plant on campus: Six geothermal wells were installed beneath the Joan C. Potente Chapel. Inside these wells, a food-grade ethylene glycol solution circulates, providing temperature control for the chapel. The only energy used to heat and cool the chapel is the electricity needed to run the pump and fan.
- Building Information Management technology is used in all construction projects. BIM allows architects, engineers, builders and campus officials to see a 3-D model of a building, leading to improved accuracy, fewer change orders, and less construction waste. Designing buildings in three dimensions instead of two has reduced construction waste by an estimated 70 percent and change orders by an estimated 80 percent.
- Permeable asphalt on campus allows rainwater to seep through the surface into the ground, instead of being carried into drainage systems. Rainwater permeates the asphalt and runs off in collectors under the street, allowing for natural filtration and cleansing of pollutants, and reducing the number of pipes and inlets that must be places in tree root zones.
- Construction materials are purchased locally whenever feasible to reduce energy used for transportation.
- The white roofs of Tarble Athletic and Recreation Center and Tarble Arena were designed to reflect heat and save energy.
