Harrison Jr. Upper School Building Middle School building with Leadership in Energy and Environmental Design (LEED) Platinum Certification, designed by architect KieranTimberlake Associates and landscape design by Andropogon Associates. The wood-clad building was designed around a sustainable use of water and energy, exemplified by a constructed wetland in the center of the campus, with many species of plants, as well as turtles and fish, part of a wastewater recycling system designed by Biohabitats. On the interior, the building uses thermal chimneys and louvers that admit diffuse light to limit the need for artificial light and thermal control. Lastly, the building contains a centralized mechanical plant that uses less energy than normal, much of which is produced by photovoltaic banks on the roof. The materials used and the environmental technology are referenced architecturally and made accessible to students, either physically, or by explanatory signs, as an educational feature.
