Over five years beginning in 2010, Kingston General Hospital in Ontario, Canada, conducted a $10 million upgrade to the energy systems of multiple buildings on its campus, ranging from structures built in 1835 to new buildings, reports TheWhig.com.
More than 9,500 light fixtures were replaced, along with 250 windows. Air-handling systems were upgraded, building envelopes were insulated, and oil-fired boilers were replaced with gas-fired boilers. The facilities manager said it was a challenge to connect existing systems with new building automation controls.
The upgrades have already netted the hostpital more than $800,000 in energy and water savings, reports TheWhig.com. Capital costs for the upgrades were reduced through grants of $500,000 from Ontario’s saveONenergy retrofit program, which helps businesses.
The hospital partnered with Utilities Kingston and the Independent Electricity System Operator, which operates the electricity market and directs the operation of the bulk electrical system in Ontario, says TheWig.com.
The hospital has earned a 78 out of 100 energy score on the North American Energy Star Portfolio Manager.
