Brown Public School Addition

Award Winner : NRB Modular Solutions
Architectural Excellence : The school board needed to add 2 classrooms for their new Full Day Kindergarten Program, but due to the restricted site in this densely populated urban area the classrooms needed to be stacked. This two story addition was attached to a three story elementary school, connecting at the ground and first floor levels. The exterior brick finish matches the existing school and an architectural aluminum panel band was used around the top perimeter and the canopy to give it a more distinctive appearance. The interior has a durable porcelain tile floor finish in the stair towers and hallways with a bright vinyl tile in the classrooms. The lower floor is used for the new Full Day Kindergarten program classes, while the upper level is a music room. At the top of the stairs a vestibule was added with insulated doors to help buffer the sound transmission. Large high efficiency windows provide excellent day lighting and views for the students.
Cost Energy Effectiveness : The energy efficient building envelope design combined with the hydronic HVAC system, the reduced lighting levels and the use of occupancy sensors have the building performing significantly better than the Model National Energy Code of Canada; resulting in expected operational cost savings. Additionally, the small site had artificial turf for sports and track and field, and access to the location without damaging the area for the addition was extremely restricted so building this addition off site may have been instrumental in reducing potential site restoration costs.

Technical Innovation : The use of structural recycled steel framing allowed the customized shape that was needed to “fit” the new addition on to the existing school. Because the school had angled walls, the new modules had to return back in to the existing building on a 45 degree angle in order not to block the views from an existing classroom window. Pre-poured concrete floors replaced the typical slab on grade for the ground floor, and helped achieve the required fire rating between floors and reduce sound transmission. The sustainable design includes a building envelope offering superior thermal performance. R20 spray foam insulation was applied to the floor assembly and R20 rigid insulation is on the exterior of the steel wall studs in horizontal “Z” bars with another layer of continuous R6 rigid insulation over that to significantly reduce thermal bridging. Windows were insulated glass in high efficiency aluminum frames with warm edged spacers, with low emissivity coating (Low E) on two faces.
