Originally dubbed "New House," Stever House was the first university residence hall in the U.S. to achieve LEED certification. The building's energy use is 31% below standard; a CMU wind power contract supplies a portion of its energy. Individual fans and operable windows deliver fresh air to each room. Over 97% of construction waste was diverted from landfills.

LEED Green Building Features
The site minimized negative environmental impacts and utilizes existing infrastructure. It has convenient access to public transportation; bicycle/pedestrian means of transportation are supported. No additional parking spaces were added to the site. A white roof was installed, designed to minimize urban heat island effect. Exterior lighting has been designed to minimize light pollution. Native vegetation was used throughout the site. Over 50 ash and serviceberry trees are a main feature of the landscape.
No potable water is used for landscape irrigation. Native Western Pennsylvania trees, shrubs and grasses eliminate the need for an irrigation system, reducing capital costs.
Energy & Atmosphere
CMU purchases Green-e Certified wind power for the campus. Computer modeling expects 31% less energy than a baseline model regulated by ASHRAE/IESNA standard 90.1-1999. There is an ongoing plan for optimizing building energy performance. Mechanical systems in the building were designed for appropriate use patterns and occupant control. Extensive building commissioning has occurred to ensure maximum energy efficiency. Measurement and verification is used to track energy use. Energy-efficient washer machines have been installed.
Materials & Resources
By utilizing a local sorting/recycling facility, over 97% of construction waste was diverted from landfills. All major building materials (concrete block, precast concrete planks, face brick) were extracted and produced locally. Materials with recycled content were selected. FSC Certified wood was used throughout the space. Dedicated recycling stations have been located on each floor next to the elevator and study rooms. Separation and recycling of glass, plastic, paper, metal and cardboard has been taken in effect.
Indoor Environmental Quality
An individually controlled 4-pipe fan coil unit has been installed. Each dorm room receives a fresh supply of air, replacing 10 percent of each room's volume per hour. Operable windows allow residents to have control over their rooms' air quality. The building is a non-smoking building. Construction IAQ management plan was implemented during construction and before occupancy. The building complies with ASHRAE 55-1992. Ongoing air monitoring occurs. Low-VOC materials improve air quality. The site is designed to control indoor pollutant sources and sinks, and is also designed to ensure acceptable acoustic properties. Split task & ambient lighting increases thermal comfort. Daylighting and exterior views exists for 90% of the spaces. Viral and allergy related sickness are expected to decrease compared to other campus housing. Health of resident hall expected to be among highest in the nation.
