Environmental Sustainability Report
Building Construction, Renovation and Maintenance
With the passing of the bond referendum, UNC-G will have many exciting campus projects.
With these projects, UNC-G will be testing and implementing sustainable products and
practices such as:
Low mercury light bulbs
Fluorescent lighting instead of incandescent lighting
Vendor Misers—sensors that only turn on vending machine lights when a person is
in the room
Water recycling in Physical Plant's new truck wash bay
Driveway areas made of permeable surfaces around the newly renovated Elliot
ELLIOT UNIVERSITY CENTER
The Elliot University Center (EUC) renovations and construction include the following principles of sustainable design as outlined by the architect:
By far the most sustainable feature of this project is the fact that we
are reusing almost the entire structure and skin of the existing EUC. By salvaging the framework of the existing building, we have minimized the
disruption of the existing site, save the energy that would have been devoted to demolishing, removing, and disposing of the existing structure,
and we have eliminated both the energy and material expenditure that would have been required to replace the existing building with new construction.
In the process of renovating the existing building, we have abated such
potentially hazardous materials as asbestos and PCB's and ensured that these
materials have been disposed of in an environmentally responsible manner.
We have replace the inefficient mechanical and electrical systems of the
EUC with code compliant ,energy efficient systems. We have replaced windows
and doors with energy efficient products that feature insulated glass with low e-coating in thermally broken frames and added additional insulation to
the exterior walls.
The long range plan for the EUC calls for a large front lawn to minimize
storm water runoff. The interim plan provides a temporary gravel parking lot in this area, which creates less runoff than impermeable paving would
The landscaping plan for EUC features local plants requiring less
watering, pesticides and fertilizer usage.
Many of the materials used in this project are either recycled or are
The brick and precast concrete were made locally from local materials
contributing to sustainability by saving transportation energy.
The following green building features will be used in the new science building as outlined by the architect:
The new science building included the design of an erosion control plan.
The building as an area devoted to the separation and collection of recyclables.
Specify a minimum of 20 percent of building materials to be manufactured
Prohibit smoking in the building to improve indoor air quality.
Employ permanent entry way systems to capture dirt, particles, etc.
Energy efficient lighting with T-8 lamps and electronic ballasts was
designed in accordance with the NCSBC Energy Code to limit the amount of utilized interior and exterior energy.
Waste heat will be recovered from the exhaust air stream via a "run
around" piping loop.
Fume hoods in the labs will have sashes that model the amount of exhaust
air based on position while maintaining a 100 fpm face velocity. Many fume hoods will have occupancy sensors that will reset the face velocity from 100
fpm to 60 fpm as needed.
A variable volume air distribution system will be used in the teaching
areas to reduce the amount of conditioned air delivered to the space based on room thermostat set points.
Chilled water pumps will be controlled by variable volume frequency
drives that will allow the chiller to operate at the load required instead of a steady amount.
Enthalpy economizers will allow "free-cooling" in the teaching areas by
using outside air as necessary to cool the space thus reducing mechanical cooling.
