Price displacement diffusers installed at Manitoba Hydro HQ
November 17, 2011 - Manitoba Hydro Place, a major energy utility for the province, has completed its new 695,250-sf headquarters in downtown Winnipeg, calling it a “truly groundbreaking building in terms of energy efficiency”.

According to Price (an air distribution products and services company that aided with the construction), superior energy efficiency was a mandate of the design throughout the facility, and delivering ventilation air in an energy efficient way was essential.
The design called for high ceilings in the gallery, but should overhead mixing ventilation be used to condition the space, a significant amount of energy would be wasted cooling the unoccupied zone in the upper levels of the gallery, explained Price.
“However, if a ventilation system were installed at eye-level, as is common in displacement systems, it would be essential that the diffusers used be integrated into the architectural design vision for the gallery,” says Price.
The design team at KPMB Architects noted that since displacement diffusers are at eye-level, and not in the ceiling, they must fit into the architectural design of the gallery. To meet this criteria, Price supplied customized black DF1R diffusers that were recessed into the wall and featured false corners so the diffuser had no breaks from one end of the room to the other.
“This made Price displacement ventilation a natural choice,” said the company, adding that by not conditioning the air above the occupied zone, displacement ventilation results in the dual benefit of improving air quality and saving energy in spaces with high ceilings.
