Canada being located so far north from the equator has one of the largest temperature ranges in the world reaching temperatures from 40 degrees to minus 40 degrees Celsius. The natural conditions depending on the province in Canada have very limited summer months where ideal conditions for outdoor activity can be seldom found. The current globalized citizens require new forms of nature in order to meet the demands of modern exercise. Engagement with nature can then be quantified, translated and processed from work to worked out. A nature that is more real is needed, one that blurs the boundaries of inside and outside, summer and winter, nature and urbanity. This entailed an interior park approach to designing a large scale athletic centre. The main attraction is the solar panel array glass roof which resembles a forest canopy and also acts as a giant battery. Even with the entire building being made from glass, the facility is still able to reach a LEED bronze energy efficiency operating within Canadian climate. With geothermal climate control, a swimming pool that doubles as a heat sink, efficient distribution of solar gains and convective forces through a solar chimney that acts as an indoor climbing wall, a fully sustained evergreen climate can be maintained year round for recreation.
