NAU College of Engineering
North Arizona University has earned a Gold rating in LEED Certification for its renovation and expansion project of the College of Engineering. The building is extremely student oriented having flexible work spaces and onsite opportunities to learn about environmentally friendly practices in mechanical systems from building itself.
The newly built portion of the building has been insulated using R-19 Batt insulation for the walls and R-30 for the roof. Both the existing portion of the building and the new build portion make use of high performance glass for all windows.
A highly efficient lighting design has allowed the energy use to be 38% below ASHRAE 90.1 maximum allowable figures.
Energy conscious features of the building’s HVAC system include use of demand controlled natural ventilation and variable air volume systems able to operate at partial loads. For this type of building with a highly variable occupancy, a DCV, VAV system is likely to result in considerable savings.
Overall, the building as designed will have the potential for 32% energy cost savings as compared to ASHRAE standards. In terms of yearly savings, the energy efficient designs of this building will save $21,660 in utility costs per year.
