A 12,486 sf purpose built wedding centre and even facility in Innisfil, Ontario. Significant building features are heavy-timber framed construction targeting zero-carbon levels of energy performance, with no combustion appliances or HVAC systems on site. Space conditioning is supplied by an advanced AWHP through radiant hydronic slab heating and cooling, together with a passive solar collection and distribution strategy using the slab as a ‘thermal battery’, where verandas provide shading to limit heat gain in Summer. This state of the art facility features a main reception hall and ceremony space suitable for gatherings of 126 people, with optional capacity for future expansion. The proposed building replaces an open-air pavilion that was built for the Greek Orthodox Church Community formerly known as Panarkadian Park.
