PROJECTS
Mayo Replacement School, Mayo, Yukon Territory
Canadian Entry in the International Green Building
Challenge, 2002
A CANMET C-2000/CBIP Project
$5.4 Million
This school serves an isolated community of the Na
Cho Nyak Dun First Nation, 400 km north of Whitehorse,
replacing a dilapidated collection of trailers. As
the largest structure in town, this 3,300 square metre
school is designed to accommodate a variety of needs
for the entire community.
The Mayo school is among the highest-scoring Canadian
entries in the prestigious and demanding Green Building
Challenge process, an international biannual event
involving 24 countries in 2002. For the 2002 Canadian
submissions, the national committee selected three
projects from 20 applicants – the Mayo school
was one of these (another of our projects, Red River
College, was also selected). These projects were then
evaluated under GBTool as part of the Challenge, and
both of our entries scored high compared to previous
Canadian Challenge projects.
This project is the first school and only the second
building north of 60° to meet the requirements
of the CBIP program. Energy consumption and cost savings
relative to the Model National Energy Code (MNECB)/CBIP
Reference were 48% and 46% respectively. In spite
of the remote location, the extreme climate and the
aggressive sustainability objective, the building
came in 5% under a conventional budget for this type
of building.
The building achieves exceptional energy performance
with a compartmentalized HVAC approach incorporating
simplicity, elegance and effectiveness. Individual
room ventilation is demand-controlled by occupancy
sensors. The building also uses a dual-fuel electric/oil
heating plant to take advantage of local availability
of off-peak electricity and groundwater cooling.
Other features include triple pane spectrally-selective
glass in operable windows, extensive daylighting using
generous vision and clerestory glazing with automatic
dimming control, and careful material choices based
on environmental criteria. Low-flow plumbing fixtures
are used throughout.
We provided design facilitation conceptual engineering,
energy simulation, and detailed design support addressing
all aspects of energy, environmental and functional
performance of the architectural and building systems.
