MacPherson Engineering provided mechanical consulting services for The Regina Provincial Correctional Centre replacement project, completed in 2009. It replaced the original 1913 facility, and multiple greenhouses and work camp buildings. The new facility consists of new Administration Building, Remand Unit and High Security / Medical Building all interlinked with corridors. Overall area of 10,131 sq. m. of facility area.
Mechanical System Description
Each cell included two bunks adjacent to the exterior wall. Perimeter radiant wall heating was used to warm the wall surface to room temperature, resulting in even space temperatures. Radiant wall cooling for the cells was provided by imbedding tubing in the precast concrete demising walls between the cells. The use of these systems has resulted in very close temperature control within the cells and all components completely out of sight of the inmates. A radiant wall heating and cooling system with piping imbedded in site-manufactured pre-cast wall panels was the first such system in Canada at that time. Due to radiant heat and high temperature drop heating coils in air handlers, the units are able to use condensing boilers to their maximum energy efficiency.
