The entire complex is on a north-south axis due to the proportion of the site; however, classrooms are oriented on an east-west axis, with most having a southern orientation. and interior acoustic batts made from denim by-products. A special effort was made to “buy local.” Since state funds financed the school, materials were purchased from companies located in Pennsylvania whenever possible. The building team was fortunate that many suppliers and fabricators are located in Pennsylvania, New Jersey and New York. Post-Construction Achievements The school opened on schedule for the start of the 2010–11 academic year and soon after received LEED Platinum under LEED for Schools v2.0. But more rewarding for the designers was learning how much students wanted to attend the school. Designed for 400 students, Kensington High School for the Creative and Performing Arts opened with 550 students and a waiting list. A heat pump serves each classroom. Heat pump closets are accessed from the building corridors, allowing units to be maintained without disturbing classroom activities. The separate closets also mitigate noise generated by the equipment. Students and teachers took great interest in their new building. The designers conducted a tour for a group of students and teachers, highlighting the green attributes incorporated in the design, and now those students and teachers give their own tours to friends, families and dignitaries. Teachers use the school as a topic of study for broadcasting, art, history, science and math.
