20 21 Sustainable Design continued from page 19 SPRA sought to maintain a constant temperature on the outer wall by using precast concrete panels, fabricated on site, with radiant tubing that enables the flow of heated or cool water inside. 470365_ONeill.indd 20 ■ THE ROYAL 1 ARCHITECTURAL INSTITUTE OF CANADA/L’INSTITUT 3/13/10 ROYAL 9:44:23 D’ARCHITECTURE PM DU CANADA PHOTO : SPRA/CPSP remand unit, 50 high-security beds, 10 medium-security beds, a 12-bed health-care unit, an inmate admission and discharge section, a visiting area and an interim administration building. After the new facility was being built, the old one was torn down. But maintaining round-the-clock security for on-site workers, staff and inmates was paramount during the project. « We started the design a year before construction of the first phase began in September 2006, which allowed us to reconfi g- ure a secure boundary around the facility to keep it operating, » explains Patrick Kelly, MRAIC, a principal with Saskatchewanbased P3 Architecture and project director for SPRA, a joint venture involving P3 and two other architectural firms, ONPA Architects of Edmonton and AODBT Architecture and Interior Design, another Saskatchewan firm. A two-metre construction fence was added about three metres from the RPCC’s secure perimeter. As Award magazine outlined in a profi le of the facility in the August 2008 issue, the RPCC’s other security features include : an IP-based closed circuit television monitoring system with networked digital storage capacity of about 150 CCTV cameras, along with detention-door control and intercom systems for the entire site that can be monitored on operator touchscreens. Kelly explains that SPRA also had to ensure that the project was minimally disruptive. For instance, the site is located atop an underground aquifer. So, the design team decided to use Continuous Flight Auger piles to ensure there was no disturbance toeither the aquifer or the facility’s operations. Other details were intended to make the new facility user and environmentally friendly. Saskatchewan’s Ministry of Corrections, Public Safety and Policing wanted inmate beds placed near the outside wall, on the opposite side of the door in their cells. Given Saskatchewan’s harsh climate – particularly with its subzero winter temperatures – SPRA sought to maintain a constant temperature on the outer wall by using precast concrete panels, fabricated on site, with radiant tubing that enables the fl ow of heated or cool water inside. That feature was one that put the project on the path toward LEED certifi cation. Other green details include a white refl ective roof coating to prevent a heat-island effect ; a 75-per-cent minimum waste diversion from construction and demolition ; and a 20-per-cent reduction in water use through the facility and site, partly the result of water-effi cient landscaping. Though the design team was unable to obtain low-fl ow toilet and sink units for the cells, low-fl ow fi xtures were installed in showers and washrooms. Small windows in cells limiting the amount of light entering some areas and high lighting levels at night meant the project could not meet the LEED standard for lighting and light pollution. But that’s okay, says Kelly, who explains that when designing a correctional facility, security concerns sometimes trump such requirements. « We don’t use LEED as a checklist, » he says. « We use it as a gauge on best practices for sustainability. » ■
