All construction and renovation at Carthage follows green principles.
The geothermal plant for the Joan C. Potente Chapel saves approximately $2,000 per year in energy costs.
The energy-efficient design of the new Student Union is projected to save approximately $24,000 per year in energy costs.
The TARC's white roof reflects heat and saves energy.
New and renovated campus buildings incorporate methods to reduce energy consumption, including day lighting, occupancy sensor lighting controls and demand-controlled ventilation systems.
Construction of the Oaks Village, Carthage's newest housing option, involved extraordinary measures to protect trees in the area: An arborist was on the original design team. All contractors must pass training by the arborist before digging. Fences continue to protect trees and their root zones near construction of the fifth Oaks building, and if a contractor must venture into a protected area, an arborist first examines the work to be done.
The new Student Union has been 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 will feature a
rain garden to manage storm water.
The College recycles building materials whenever possible. 85 percent of the former Siedemann Natatorium materials will be recycled as the building is renovated into the new 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.
