Of particular interest is how the tension fabric structure enhances the performance of HVAC systems, both passive and active. After working with the facility, Terry Smith, P. Eng. of Edmonton based TWS Engineering Ltd. said: “The fabric structure at River Cree provided many HVAC efficiencies that (can) exceed many traditional construction methods.” The weather tight fabric panel attachment system - propri- etary to Legacy Building Solutions- is key to this capability. “The unique construction methods used for this structure al- lowed for minimal air leakage through the wall assembly as well as at the building’s fenestrations,” Smith said. “This lets the building be adequately ventilated without the need to introduce excessive outside air. Tighter control of the building’s operating conditions was also achieved, which per- mits the structure to operate more efficiently, with minimal air quality issues and lower than average building heating re- quirements.” In addition, the building’s structure and materials have been designed to stand up to the infamous Chinook winds that gust through the area at speeds in excess of 60 mph. At the Venue, the acoustics - a critical aspect of any per- formance venue - have passed muster by both musicians and the neighbours. A previous building on the site (since demol- ished) had drawn complaints from the community about noise leaking during concerts. With its batt insulation and interior fabric liner, the new structure channels crisp, clear sound throughout the hall, but not beyond its walls. “The interior fabric skin of this structure allowed for mini- mal reverberation within the venue,” noted Smith. “This pro- vides the client with high quality acoustic attenuation in the entertainment space.” The liner also works to deaden the sound generated by the mechanical systems that are mounted on or adjacent to the main structure. The building’s acoustic properties were fur- ther refined by a special noise absorbing admix that was added to the concrete before the floor slab was poured. The entertainment venue is the first stage of the project at River Cree Resort and Casino. Further additions are in the works.
