Vanden High School was originally built to accommodate 800 students. Through meetings with the administration, faculty, and district officials, it became apparent that the school community had enjoyed the relatively small learning community and lamented its loss as enrollment climbed to 1400 and the campus was clogged with chaotic portable placement and overcrowded cafeteria, performing arts, and administrative space. The challenge was to replace portable classrooms with permanent classrooms that would reorder the campus and make possible student identification with smaller learning communities within the new 1400 student enrollment. By adding specialized music, drama, visual and performing arts facilities, we were also able to restore an original second cafeteria for general student use. New classrooms are designed in flexible buildings housing six classrooms each and presenting different faces on each orientation, both to optimize daylighting and to create variety on the campus when they are repeated. The design of the buildings creates learning communities within the total campus, flexible classroom groups within the learning communities, and a variety of flexible classrooms, offices, alcoves, and nooks within the buildings that house a hierarchy of activities from large group to individual learning. By defining courtyards of differing character with the new classroom buildings, art studios and music rehearsal spaces, learning communities in the arts and in technology have physical areas of the campus to call their own. At the same time the campus is organized to allow for change in student interests and emphasis in future years. Each six-classroom building also includes a teacher workroom and a shared flexible use space that can be used as either student or teacher workspace. The school makes very efficient use of classroom space, scheduling each classroom for virtually every teaching period, making necessary provision of teacher preparation space outside the classrooms. In existing double loaded corridor buildings the modernization makes new doors into classrooms from the outside and converts corridor space to teacher prep space. This not only gives individual teachers a place to work but also encourages teamwork on the part of the teaching staff. High performance measures squeezed into the original budget and incorporated into the design include: • Energy efficient HVAC and daylight compensation lighting systems with a calculated 35% improvement over Title 24 requirements• Low slope roofs with deep overhangs over entrances and south windows • HVAC mounts on vertical walls to avoid penetrations through the roof, to prevent acoustic intrusion into the learning environment • More courtyards with generous planting that provides shade for student socialization
