After completing significant hospital upgrades last year through an energy performance contract with Johnson Controls, the 1.6 million-square-foot Royal University Hospital (RUH), located on the University of Saskatchewan campus in Saskatoon, is now seeing a huge payback, almost doubling the expected savings from energy, water and operational improvements, according to an article on The Remi Network website.
RUH invested $13.6 million to save $1.4 million per year. And in the first two reporting quarters, the total savings is already tallied at $899,192, surpassing the target guarantee by 48.2 percent.
The project team used energy analysis and on-site survey information to decide on measures to improve energy consumption, which is now in a measurement and verification phase.
Besides more standard measures with lighting, water and the building envelope, the team installed a fan wall. Two large horsepower fans were removed in place of a wall of 15 efficient fans that provide backup. Having just two fans in the operating room caused shutdowns of one wasn’t working.
