Daylighting is the key element in the Durant Road Middle School design. It reduces energy use for lighting and reduces cooling load.
Overhangs and interior baffles shield all direct sunlight while providing better quality daylighting. State-of-the-art lighting controls and an energy management system were designed to interface with Wake County’s energy management central station. The daylighting monitors are supplemented by artificial lighting through automatic (photocell) occupancy and lighting level sensors and controls. HVAC and lighting technologies allow individual teachers and management to select optimum lighting levels for each room.
Total reduction in energy use for lighting, cooling, heating, and ventilation at Durant School is 50 to 60%. (In a typical new school building in North Carolina, lighting accounts for approximately one-quarter of the total energy load.
South- and north-facing roof monitors provide daylighting to classrooms, cafeteria, gymnasiums, and other areas. There is a 30% overall increase in glazing for daylighting.
The building is oriented lengthwise on an east-west axis to optimize placement of the north- and south-facing daylighting monitors and to reduce heat gain.
The roof is equipped with a radiant barrier that blocks over 90% of the radiant heat.
There is low-e glazing throughout, for all low-view glass and clear double glass in the roof monitors.
High-efficiency lighting equipment and controls are used, including motion sensors and light-level sensors to automatically adjust conventional fluorescent lighting as needed.
An energy management system is installed. The ventilation system tailors fresh-air circulation to occupancy of the building instead of constant operation, which is typical of school buildings.

Materials selections of note include local brick and durable CMU.
The repetitive design of the Durant School offers easy and affordable construction as well as future flexibility. The choice of local and durable materials for the majority of the structure also minimizes future material wastes.
The building has an extensive recycling area for newspapers, cans, cardboard, plastic, etc. and has a minor composting program for the students.
The team was constrained in specifying greener materials due to "standard" items used by the school system.

Many existing trees were saved on the overall forested site, and those that were taken down for the school construction were utilized for on-site mulch, thereby reducing removal and transportation of materials off-site.
Stormwater runoff was effectively collected and removed until a newly developed shopping center "neighbor" across the street was constructed. Currently, stormwater runoff is an issue with the school’s adjacent residential neighbors, who are receiving the majority of the "overflow" water problems related to the new commercial construction affecting the school land and surrounding area.

Daylighting was a key element of the indoor environment. It appears to have increased productivity among students, decreased absenteeism, and shown improved student test scores when compared to statistics from other schools in the county.
Several classrooms and the main library incorporate large windows that frame trees and natural vegetation. The spaces are noticeably soothing, expansive, and vibrant. The library, with its superior light, seems to have a significantly low noise level.
The gymnasium and cafeteria also use daylighting. The team found that some teachers insisted on using artificial light in the gym even when daylight levels were more than sufficient.
Daylighting is provided by roof monitors with baffles to diffuse the light. Quality is excellent.
