The Scarborough Hospital (TSH) in Toronto began implementing an infrastructure upgrade to improve the comfort and safety of patients, staff and the community with energy retrofits that promise greater efficiency, cost savings and environmental compliance, according to an article on The Wall Street Journal website.

The hospital has begun a series of equipment retrofits at its general campus designed to create a more comfortable indoor environment, reduce long-term operating costs and meet the environmental standards set by the Ontario Ministry of the Environment (MOE). 

The measures will be financed as cash-flow neutral at no cost to the taxpayer, and will be funded solely by energy cost-savings generated by the retrofits over the long term.

Ameresco Canada has been contracted to study, design and replace the existing chillers at the hospital's general campus. The two aging chillers were replaced with two energy-efficient models that comply with the MOE ban on chlorofluorocarbon refrigerants (CFC), which are known to accelerate the rate of global warming, the article said.

Other key planned improvements for TSH include boiler plant upgrades to recover waste heat, better air-handling controls, installation of energy-efficient lighting and the reduction of campus water consumption levels.
