The Davidson County Community College (DCCC) in North Carolina has started to renovate an energy-efficient green home as part of its “green mission” for environmental sustainability and preservation.
Like the LEED-certified residential home laid out by Tulane and Neighborhood Housing Services in New Orleans, the green home in Davidson County is designed by a group of students.
At the same time, the more than 25 DCCC students view the renovation project for the 1,000-square-foot house along Old Greensboro Road as a learning opportunity for them to experience the actual steps in building an efficient home.
The house, which is owned by DCCC Foundation, is located just across the DCCC campus.
Hedrick Creative Building provided the consulting and contractual services.
According to Bruce Bowman, DCCC’s HVAC instructor, the renovation is the first green home project undertaken by the students.
The DCCC students installed energy-efficient heating, ventilation, air-conditioning, and insulation materials that include a two-stage heat pump with a 19.5 SEER minimum rating, an energy recovery ventilator and a GeoSpring heat pump water heater.
Bowman explained that the energy recovery ventilator is capable of efficiently exchanging household air with outdoor air due to the its construction.
It would then be impossible for air to penetrate the insulation materials because they are made of icynene that does not allow for cracks.
Bowman said the green home will be inspected by the Davidson County Inspections Department and a home energy rater who will conduct “air flow and leakage, infiltration and ventilation verification.”
The two-bedroom green home has added a sun porch in addition to its bathroom, kitchen, dining room and living room.
The renovation project includes conversion of the basement into additional bedrooms and a bathroom. Moreover, the green space outside the house will be developed by students from N.C. A&T State University who study landscape design to become a community garden.
The house is intended to accommodate international students next school year.
The National Association of Home Builders’ National Green Building Standards will soon certify the green home with Emerald Level.
The renovation project has drawn the support and donations from different firms such as the G.W. Smith Lumber Co., Atrium Windows and Doors, Unilin Flooring and Formica, which provided the construction materials; CTRL Electric and City Electrical Supply which donated electrical supplies; Trane, GE, N.B. Handy and Quietflex Manufacturing which furnished the HVAC and water heating equipment.
Usually, one class would undertake two to three installation of materials, but DCCC students took on eight projects this year.
