Architectural Excellence : Havergal College is a leading university-preparatory day and boarding school for girls since 1894 that today strives to raise awareness about the significance of sustainability. Located on a 22-acre site with many heritage and contemporary buildings, when they needed a new Art Studio space they looked to buying a custom relocatable classroom for the speed, flexibility and greener construction practices. Because an open art Studio works best with natural light, the building has 9’ ceilings, the north face is fully glazed from floor to ceiling with high-efficiency windows and high windows were added to the south face. The exterior is recycled corrugated horizontal steel cladding with a large accenting architectural metal panel fascia and pot lights to illuminate the front face. Inside, mold resistant drywall is painted, and the sheet flooring is maintenance free. Topping off the classroom’s environmental design is a 100% green living roof, visible from the higher campus buildings.

Cost Energy Effectiveness : The college chose to use a relocatable classroom design for the future flexibility of repurposing it for another use or moving it to another location (or owner) should the need arise. Despite the simplicity and cost efficiency of the overall layout, the building envelope still engages all of the elements that can be found in permanent construction, including building science, durability, and with a life cycle of 35 plus years. The restricted site needed the classroom to be a maximum size and to be installed with as little disturbance to the surrounding campus and classes as possible.

Technical Innovation : The classroom is all steel post and beam construction with additional structural elements added to support the loads of the green roof materials and vegetation. The design of this classroom considers a whole building approach for energy conservation. The building envelope has R 20.4 rigid insulation applied to the exterior of the wall studs within horizontal “Z” girts with another layer of R6 over to eliminate thermal bridging. Roof assembly is R31 and the floor is R28. Windows are high efficiency frames with Low E coated insulated argon filled glass and warm edged spacers. The HVAC is a unit ventilator with an energy recovery ventilator; electrical has occupancy sensors and T-5 lighting. The green roof used here will be a teaching tool for faculty and students.
