Watauga High School, Boone, N.C.

The LEED Silver high school is intimately tied to the culture and values the community places on its environmental conscience. Developed around a ground-source geothermal well field tied to a water-source heat pump system, the latent load and energy recovery is handled by a Dedicated Outside Air System and the sensible load by the WSHP system. This system does not require a boiler or chiller, thereby reducing fossil fuel consumption. Individual controls allow for comfort and control, while large assembly spaces are handled by sensible demand load. Additionally, the building is oriented so that solar gain and daylighting are most efficient, while landscaping and site impact required minimum upkeep and expense. The school’s energy efficiency is a result of the careful examination of how all systems interact and taking the appropriate measures to maximize the efficiencies gained by that interaction.

The project features curved roofs that blend in with the surrounding mountain community, and were designed with heavy snow loads in mind. McElroy Metal supplied 67,000 square feet of 24-gauge Charcoal Gray Kynar coil for on-site rollforming, in addition to 40,000 square feet of pre-formed Maxima 216 ADV at Gabled roof areas in 24-gauge Charcoal Gray Kynar. The on-site rollforming and curving was required due to design features and specification requirements.
