This cooling plant is located directly east of the Edmonton Clinic on the University of Alberta campus. The building contains two floors and a 25 foot basement. The height of the roof is about 45 feet above the main floor. The main purpose of the building is to house heavy cooling plant process equipment; however, a portion is used for light industrial fabrication and for office space.
Work on the project included 32 geo-thermal wells reaching 70m below the ground with a ground-source heat pump, which circulates a mixture of food grade antifreeze and water through the network of three quarter inch vertical piping. All of the energy required by the Mosaic Centre is produced on this site and by solar photovoltaic modules.
Some of the unique features of this sustainable, LEED® Gold building include various curved wall panels, two elevators, demolition of civil works, as well as an extensive shoring system due to severely limited access and lay down space.
There was very limited space available for the staging and storage of materials. Deliveries had to be organized to suit availability of space and tools. Material that were no longer required had to be removed from site in a timely manner. With our efficiency on site despite limited space we still managed complete this project on time and alongside budget.
Another interesting fact about the building's sustainability aspect is that in order for it to be certified for the Living Building Challenge, it must produce as much energy as it uses over one calendar year. As the winter months do not produce an abundance of solar potential, most of the energy is gathered in the summer. The system over produces and the surplus energy is “stored” in Edmonton’s electricity grid (used by the neighborhood). In the winter months, electricity is “withdrawn” from the grid when the system cannot produce enough to power the building.
