Wyndham Gardens Airport

Opened in October 2015 and located only minutes away from the Calgary International Airport, the Wyndham Garden Calgary is a soon-to-be uncovered jewel on the hospitality scene in the city.  The building is highlighted by a complex central climate control system that earned Klass Mechanical Sales the award for City Multi Project of the Year

The specifications asked for equipment that ran as quietly as possible, due to the hotel’s proximity to the airport. After considering PTAC units and ruling them to be too loud, a City Multi VRF system was installed.   The feedback since opening from both the customers and the staff has been positive, namely that the rooms have been quite comfortable and quiet – exactly what the doctor ordered.

Fort MacMurray International Airport Terminal

Opened in June 2014, the Fort MacMurray International Airport's newest terminal is a thing of beauty. The $258-million dollar terminal is five times larger than it's older counterpart, and features four aircraft bridges & eight aircraft parking stands. The terminal is one-of-a-kind, an environmentally sustainable facility built for the harsh northern climate.

The air terminal building is climate controlled by Mitsubishi Electric double heat recovery water source systems, utilizing state of the art variable refrigerant flow technology. These systems provide building comfort conditions by allowing simultaneous heating and cooling operation as required at various locations in the building while at the same time maximizing building energy efficiency. Computerized control and energy management programs optimize the energy recovery process to ensure the least possible energy consumption and minimizing operating costs.
