A generous amount of natural light to all classrooms is achieved through the use of high clerestory windows to the north of corridor and south of service spine. All classrooms receive southern diffused light from two directions, no matter where they are located. Natural light in teaching spaces is critical in this part of the world where winter sun is so scarce.
energy conservation
This project has been certified as a C2000 building through the Office of Energy Efficiency, Natural Resources Canada. The building also successfully achieved the goals and requirements of CBIP (Can Build- ers Incentive Program). This is the first school and only the second building north of 60 ever to achieve this benchmark. This means it must achieve energy savings of 45% in comparison to a computer simulated benchmark building of similar size and configura - tion. When the Mayo School was modelled using DOE 2. E software it found energy consumption savings of 47.3% and energy cost savings of 48.5%. The core of the C2000 programme is its integrated design process in which architect and engineering consultants develop the design together from first concepts on so that all technical, functional and economic factors which impact the buildings performance will be considered before the design has progressed too far. GF Shymko & Associates, energy engineers, were retained by the Yukon Government and facilitated the integrated design process. Energy conservation features include photocell sensors that switch off lights when natural light levels are sufficient, use of on site groundwa - ter for ‘free’ cooling, heat recovery and motion sensors on ventilation systems and decentralised HVAC system to more efficiently serve vari - ous school zones. There are digital control systems for temperature and lighting setback operations.
materials
The school is wood frame to allow the small frame-oriented labour force in the Yukon the chance of building the project without importing labour from the south. Materials were chosen for their Yukon content: locally manufactured vinyl windows, local wood species —engineered wood products (truss joists, oriented strand board, glue laminated units, pre-engineered wood trusses and LSL slabs) are used extensively throughout the school to make efficient use of a natural resource. Interior material finishes underwent a preliminary screening process to identify acceptable products with low embodied energy and low voc’s. These include linoleum flooring, birch ply millwork, panelling, trims, locally milled pine slat finishes, low voc latex paint.
