50 | FEBRUA RY 2019 Calgary Central Library PHOTOGRAPHY BY MICHAEL GRIMM/COURTESY SNØHETTA neighbourhoods. Filled with light and activity, this prow of the building will not only serve as a beacon to those out- side, inviting them to enter, but also as a prospect for looking back out – a fitting vantage point to observe the impact of a building that hopes to re- energize the spirit of culture, learning, and community in Calgary. For the mechanical and electrical systems (Dialog and SMP Engineering were the mechanical and electrical consultants), the extensive use of con- crete helped ensure the building was successfully sustainable and adhered to TABS building (thermal active build- ing systems) specifications. A dedicated outside air system (DOAS) has been installed, which deliv- ers 100 percent outside air to the spaces via displacement diffusers within the pressurized raised access floor plenum, according to Matt Parkes, LEED Green associate at Dialog. "The TABS system provides a means of heating and cooling for the public areas. Occupant comfort is one of the primary drivers in sys- tem selection and the combination of displacement ventilation coupled with radiant heating/cooling provides an optimal system for occupant comfort and also energy efficiency." Parkes adds that possibly the big- gest challenge mechanically was ensuring the systems remained out of sight. "When you wander around the public areas, it's not obvious how the building is heated, cooled, and venti- lated as you can't see any pipework or ductwork. To do this, we ran over 230,000 feet of radiant tubing within the concrete structure to provide radi- ant heating and cooling to the spaces and used the raised access floor as an air plenum. Co-ordinating the tub- ing installation with the rebar and concrete pour schedules required numerous construction and 'on the fly' meetings with the team, but it all worked out in the end and the team did an outstanding job." Having come in on time and under budget, with limited downtime being experienced by the LRT and as Kapusta proudly says, "more than two million people expected to pass through the doors over the next 12 months," this project is testimony to the great team that came together to make it possible. Dykers adds, "Calgary's new library signals a new chapter in the life of the city. By investing in their Central Library to create an open platform for making, not just taking, the City has opened a new door into a future that banks on a culture of creativity and innovation." In conclusion, Adamson says, "I feel we have changed the design for public buildings in Calgary. I'm a Calgarian and we need to up the ante of the quality of design for civic build- ings. If it can accomplish that it will be extremely important."
