Hagen Head Office
Rubin & Rotman associates
OVERVIEW
In 2004, the board of directors of Hagen, which produces and distributes pet-related goods, decided to erect a new head office, marking the approach of the 50th corporate anniversary. Located along the Trans-Canada Highway in Baie-d’Urfe, the new building consolidates all Hagen’s Research and Development operations. The site consists of two adjacent commercial lots bordered by a stream. It is spacious enough to accommodate growth, well served by public transit and municipal infrastructure and in good proximity to management and manufacturing.
The compact 5,600 m2 (60,280 sq. ft.) building is almost rectangular on an east-west axis. The building is set around a central atrium that acts as the main vertical traffic corridor, giving access to the building’s three floors from the entrance and the reception area. On the ground floor, the cafeteria faces onto the atrium. The basement houses a pet area, a workout room, showers and lockers for employees, indoor parking and mechanical equipment rooms. Company departments occupy the remaining above-ground area. Natural light illuminates most occupied areas, and optimization of system controls keeps the working environments comfortable.
Pioneering heat storage banks and a heat recovery wheel contribute to the building’s achievement of 60% energy efficiency improvement over model code. The building is heated with radiant floor-to-ceiling perimeter heating that is fed by geothermal energy. Other improvements in sustainability are due to the compact site design. Paved areas are minimized by locating vehicular traffic zones close to the access roads, and providing only the minimum number of parking spaces. The landscaping is indigenous and eliminates the need for irrigation.

wet sand heat banks
Heat is pumped into this system both at night, when hot water produced by the heat pumps is circulated in the banks, and in the daytime, when water returning from the building's heating equipment is circulated through them.

Water Conservation
During construction, shallow ditches were dug at the perimeter of the construction zone. These ditches gathered potentially contaminated runoff water and moved it by gravity to a sedimentation pit. Clean surface water was returned to the water table through the stream.

Recuperated wood
Mature trees felled in preconstruction work were recovered, dried, cut into planks and turned into soffits, wall panels, furniture components and interior decoration.

window-to-wall area ratio
The dominant contributor to the energy efficiency of the building envelope is the reduction of glazing area across all elevations. The overall building window-to-wall ratio is 27.3%. Conventional office buildings clad with curtain wall have fenestration areas of over 50%.

WATER CONSERVATION
Water for non-potable uses is drawn from nearby ponds further reducing use of potable city water.
