High Performing Buildings - Fall 2011 - (Page 20)

Building Envelope and Site Law enforcement and judicial facilities must accommodate several different occupant groups — the public, the police, the judiciary, and the detained — each with its own security requirements and circulation network. Accommodating these multiple networks can yield low building efficiency (i.e., the ratio of net to gross area), not to mention disorientation on the part of users. With the cost of such facilities being roughly $400 per gross square foot, it is imperative that this ratio be as high as possible. Since the façade is among a building’s costliest components, it is also imperative that floor-to-floor heights be no more than necessary. To maximize the efficiency of the plans and maintain a simple interior organization, we took advantage of the fact that we were dealing with a multi-story building. In a one-story police building, the cellblock must 20 HigH Performing abut spaces along the exterior wall, so that detainees can be transferred from the sally port without crossing the paths of other users. By contrast, we were able to locate the cellblock in the middle of the basement, because it is served by a dedicated elevator adjacent to the sally port on the floor above. To minimize floor-to-floor heights, we coordinated the ductwork with the floor framing, so that ducts never had to pass under girders. This allowed the ceilings to be much closer to the framing above than is normally the case, enabling the building height to be reduced by about 10%, decreasing the cost of construction and the surface area through which to gain or lose heat. Other strategies that reduced the volume of building materials included using acoustic metal floor and roof decking for sound control instead of separate suspended ceilings, leaving fa l l 2 0 1 1 Visitors arrive in a two-story lobby filled with daylight, some of which penetrates the courtroom through windows on the left or the fitness center through the glass block floor. the superstructure exposed to view wherever possible in the finished building, and using modular masonry design to reduce cutting and waste. The building’s locally sourced materials include its red brick veneer and slate roofing. Both require little maintenance, have long useful lives, and reprise the palettes of the township’s other public buildings. Low-emitting paints, coatings, adhesives, sealants, and carpets were used throughout. The site was just large enough to accommodate the building and staff and official parking. To accommodate weekday visitor parking, the municipality entered into a longterm agreement with the administrators of the church next door, to share its parking lot. Buildings david glasofer
