DESIGN CHALLENGE
With picturesque views overlooking the park and river, the main design challenge identified was to elevate the pavilion's role from its utilitarian functions into an experience that enhances and celebrates the splendour of the natural environment surrounding it.
RESOLUTION AND DESCRIPTION
Reminiscent of the experience of climbing up a tree house, ascending the gently sloping path of the pavilion is an experience that brings delight and encourages contemplation. Creating unexpected vistas, spaces plugged into the path are oriented towards selected framed views of the surroundings. The pavilion is used by different people in different ways; every encounter strives to become a unique experience. Entering the pavilion you start to gradually ascend through an open public space, you stop to admire the selected framed views of the surroundings; you reach up to the change area where you put on your skates, you find yourself gliding down a gentle slope towards a serene forest clearing, where the path leads you between the trees towards the skating arena. The gently sloped entrance lobby doubles as a public space for displaying the public art component, or alternatively a space for displaying community art contributions. The user funded functions are integrated into the design but could easily be scheduled as a future phase. The city funded base building is designed to be a fully self-sufficient building on its own. There are two alternatives for locating the art contribution: either within the public entrance lobby, or alternatively in the outdoor public area identified on the lower level floor plan.
SUMMARY OF THE TECHNICAL ASPECTS
As well as creating opportunities for framing selected views, raising the building on stilts minimizes disturbance to the existing natural habitat and allows the natural flow of water and wildlife through the site. Lifting the building also has the benefit of increasing natural ventilation allowing air flow around and under the building. The building design achieves efficiencies by utilizing traditional building methods that are familiar to the construction trades. The structure is a combination of locally sourced structural steel frame, lightweight wood construction and wood rafter roof structure. The shell of the building is wood frame construction with reclaimed barn board or FSC-certified wood rain screen cladding. Operable windows are designed for daylight and passive ventilation, with thermally broken window frames, and low-E coating glazing. Clearstory windows allow for night flushing of warm air. Green roof over structural insulated panels is employed. Rainwater runoff from the roof is collected in a below grade cistern located under the Zamboni storage room, the water is reused for toilet flushing and irrigation. The mechanical system utilizes low velocity displacement ventilation located at floor level, low flow plumbing fixtures with touch free sensors, and the re-use of grey water for toilet flushing and landscape irrigation.
