Award Winner : NRB Modular Solutions

Architectural Excellence : The building is a 12-classroom addition that was added on to another 12 classroom complex finished in 2005. The complex is steel clad, all steel, non-combustible construction which allows the large number of classrooms to be grouped in complexes of 12 without fire rating. In order to attach this to the original, NRB built a block fire wall between the two complexes and created the central entrance and vestibule. This complex is created with NRB’s PC2000 construction technology. It is completely mold resistant with the removal of almost 90% of the cellulose materials. It uses rigid polyiso insulation and vapor barrier over the exterior of the wall and roof assemblies to completely blanket the complex, move the dew point away to the outside, and thereby prevent any thermal bridging which can cause condensation in the wall and roof cavities. The interior wall finish is a paper-less vinyl covered drywall that will not support the growth of mold.

Cost Energy Effectiveness : The classrooms each have a Unit ventilator with 15 cfm ventilation per student, 3 tons of cooling to control relative humidity levels, and 15.8 kw of heating. The increased insulation values in the walls and roof, plus the fact that the insulation blankets the exterior improves the thermal protection greatly. The primary value benefit of the PC2000 design is the overall reduced maintenance requirements, and the extended life cycle that the school boards can expect.

Technical Innovation : The PC2000 design technology was developed as a solution for ongoing maintenance and mold contamination issues faced by school boards over the years as their portable classrooms were subjected to reduced maintenance and were left in place well past their intended life cycle. The building is structural steel post and beam type construction, with steel stud infill. This means that the schools can easily modify the classroom complexes. The walls are free of batt insulation so are open to breathe and provide easy access for the installation of cables and conduits without causing holes or gaps in the insulation and vapor barriers. Floor assemblies have steel decking below, making them resistant to moisture penetration.
