421 Downey Road, SaskatoonTable of Contents
IntroductionThis technologically advanced 3 storey mixed occupancy building with full basement, is located at Innovation Place Saskatoon. An integrated design process guided the project teams' decisions from conception to completion. The process allowed for the selection of energy efficient and flexible building systems to accommodate changing tenant needs. The building provides space for offices and laboratories that are classified respectively as group D and group F Division 1. Design and construction protocols employed by the team ensured the building processes were always systematically applied. Rigorous quality control strategies were instituted to verify design parameters were effectively implemented. For example, the continuity of the exterior building envelope air barrier was deemed to be critical performance characteristic. Testing of the air barrier was conducted during the construction phase with thermograph and air sealing equipment. Any deficiencies in air barrier performance identified were corrected and re-tested to verify specified design standards were achieved. To ensure design objectives were achieved at no extra cost the team did not hesitate to make tradeoffs between architectural, mechanical and lighting systems. This flexible approach was exemplified in how the team addressed the challenge of satisfying disparate needs of office and laboratory occupancies, while at the same time maintaining an environmental friendly and productive workspace.
The design minimized environmental impact, emphasized the importance of occupant health, comfort and functional performance of the building. The direct and indirect lighting systems were integrated with double and triple glazed low e, spectrally selective glazing. Load reductions were achieved through effective envelope construction, efficient lighting, building orientation, sunshades, heat-recovery, and the installation of high performance windows, which enabled the designers to select smaller more efficient and economical mechanical and electrical systems. Designers placed emphasis on indoor environmental performance. A high level of indoor air quality was achieved with the provision of operable windows and a mechanical ventilation system that provides 100 % outside air system equipped with an energy recovery wheel, which is 75% effective at recovering sensible and latent heat from the exhaust air. The low maintenance exterior was designed and constructed for longevity using block, brick, and limestone. The design was predicated on the expectation that building-operating costs would be reduced providing competitive rental space. Building Design ObjectivesThe building has 52,600 sq.ft. gross area and 42,400 sq.ft. net area on three storeys. Total 57,000 net sq.ft. The building with office and laboratory space designed and constructed in accordance with advanced building design principles. Project qualified for Commercial Building Incentives Program (CBIP) $80.000 grant. The main objectives of the project were to provide:
Building Information Summary
Building Performance Highlights
Building Systems Summary
Superior Building EnvelopeThe key to the success of an advanced building project is to construct a quality building envelope.
Productive and Flexible Work EnvironmentTop priority to provide a healthy and productive work environment.
Flexibility to Accommodate Lab Facilities
Lower Operating & Maintenance CostsThe design and construction of a superior envelope and an energy efficient lighting system allowed for selection of smaller more efficient and economical mechanical and electrical systems. Building operating costs will be reduced thus providing more competitive rental space and protect against rising energy costs.
Sustainable Design421 Downey Road was designed and constructed with a low maintenance exterior that is expected to provide a long service life. The primarily block, brick and limestone building includes a cornerstone marked with the year 2000 and a time capsule filled with memorabilia marking current events. Building systems accommodate a variety of building uses, which will help to ensure the facility will remain an economically attractive investment into the next century.
