Women’s College Hospital takes a green step forward

As part of Women’s College Hospital’s ongoing commitment to reduce its carbon footprint, the hospital announced that it has implemented Enwave’s Deep Lake Water Cooling System during Earth Day Celebrations. This means our outdated chiller that has been cooling our building for more than four decades has been replaced with a new, energy-efficient cooling model, reducing electricity usage, water consumption and our overall impact on the environment.

Women’s College worked in conjunction with Enwave Corporation to connect our facility to their Deep Lake Water Cooling System, which utilizes cold water from the depths of Lake Ontario to cool our building. Meeting legislative changes to phase out the use of ozone-depleting gases in existing chillers, Women’s College is one of only a few Toronto hospitals implementing this unique, environmentally friendly cooling system.

“After reviewing several options, we chose the most energy-efficient, environmentally  friendly and cost-effective solution,” says Dharma Lakshman, director of physical facilities at Women’s College Hospital. He further explains that this project involved the installation of heat exchangers, water pumps and changes to our existing cooling system.

To celebrate the greening of WCH, our very own Green Team Committee set up a booth attracting more than 300 visitors on Earth Day to provide staff and visitors with information about our new cooling system. The event previewed a video by Enwave Corporation, explaining how the system works.

The Deep Lake Water Cooling System will successfully keep the entire hospital cool and comfortable for our patients and staff.  What’s more, it is not just cooling our building now, but will be fully implemented into our new facility. The implementation is all part of the hospital’s commitment to working toward becoming Leadership in Energy and Environmental Design (LEED) certified.

“Most people won’t even notice the difference,” explains Lakshman. “What is important – and exciting – is that we are being proactive and going green.”
