Queensway Carleton Hospital (QCH) is a 264-bed hospital located in the west end of Ottawa, Ontario, Canada that delivers short-term primary and secondary health care.

Installation of combined heat and power (CHP) systems was one of several options that QCH implemented to achieve its energy savings goal and minimize the greenhouse gases (GHGs) produced as a by-product of its operations.  It also provides a level of resiliency in case the normal power was curtailed for an extended period of time (ie. Ice storm).

The CHP project scope of work included:

• Installation of the prime mover with heat recovery, both mechanically and electrically
• Heat Recovery Steam Generator, which uses waste heat from the engine’s exhaust stack, converts to 15 psig for use in the hospital space heating system
• Heat recovery from the engine jacket, aftercooler and oil cooler, for the purposes of pre-heating domestic hot water for potable use, kitchen and laundry.
• Selective catalytic reduction system
• Sound booth that limits the ambient noise to less than 75dBA during CHP operation
• Floating floor that limits the transmission of structure borne noise
