The Water Centre is the first phase of the urban redevelopment of the City of Calgary brown field industrial yards into a civic operational and administrative centre. The 16,000 m2 building combines the previously autonomous Water Resources and Water Services departments, to house 460 administrative staff and 360 operational staff. The building provides open office stations for all staff (irrespective of status), meeting and quiet rooms, conference facilities, crew changing and gathering areas. The project?s industrial and residential context demanded a dynamic yet sensitive response to the site. The building is aligned to a major road (which demarcates a historic rail line) to provide an urban edge on the north side of the site and to use the building form to establish and protect the garden to the south. The Parti Sketch identifies the major elements of the long narrow building - the curve relates to the historic context of the road and railroad; the horizontal line, the face to the sun; and the diagonal, two departments merging into one and the two aspects of operations and administration. The narrow floor plate optimizes daylight to all workplaces. The long layout of the building allows for the public west entrance to be placed within pedestrian access to the transit station and nearby river path system while the east end connects directly with the site?s existing vehicle service zone. The building is 4 storeys at the west end falling through the sloping site to 5 storeys on the east. The curved section of the building is representative of a ?blanket? that shelters and protects the south glazing and the garden. On the south side, the open offices are shielded from direct sunlight by the roof overhang (the Porch), the four storey atrium and meeting rooms while on the north edge, double height studio windows address the city skyline. The placement of the linear stair and overlooking landings along the atrium promotes communication and interaction with views to all Water Centre departments. The clarity of the section provides the occupant a definitive understanding of where they are in the building. The one storey operational wing is covered by a green roof. The adjacent garden includes radiating paths and direct pedestrian connections between existing and future facilities and provides open space for the denser surrounding residential communities as well as for visitors and staff. A series of native plantings will be introduced in the coming seasons. The industrial quality of the galvanized aluminum cladding is tempered by its ability to reflect the quality of the ever changing light that is unique to Calgary. The green/blue pattern of the curtain wall glass on the south echoes the shimmering of water and is appreciated from within the atrium as well as from outside the building. The Water Centre is the first civic office building to exceed the minimum LEED silver standard. It marries the aspects of environmental fit and functional program into an iconic form that is symbolic of both its user and of its context.
