Win-win: Michener Institute saves money while saving the environment

Michener
In 2018, the Facilities team at the St. Patrick campus of the Michener Institute of Education at UHN found a way to save money while also reducing the building’s use of chemicals, water, and energy. The building’s cooling system was not operating at maximum efficiency due to heavy scaling of calcium phosphate in the condenser. This scaling led to an increase in energy and water usage in the summer of 2017, and it also required regular acid cleaning. As you might imagine, this type of cleaning comes with both monetary and environmental costs.

Meet the Intern!

For those that haven’t met me yet, I’m Sinthusha, the new sustainability co-op working with Lisa Vanlint! I’m pursuing a double major at the University of Waterloo in Science and Business. When I agreed to this job, I thought I knew what I was getting myself into but I was wrong, very, very, very wrong, in the best possible way 🙂 In the two months I’ve been here, I’ve done so much more and learned so much.


Thank you Kelvin Chan Tung and Blair Gage for remembering to shut the sash of their lab’s fume hood! This saves so much energy! (like, more than a house)

UHN’s CEAL Lab Installs New Lighting System

An innovative new LED lighting system has been installed at the Toronto Rehabilitation Institute’s CEAL lab (Challenging Environment Assessment Lab). Researchers in this lab conduct world class experiments to advance knowledge in mobility, aging, accessibility, design safety, and much more. The lab itself is a unique space with high ceilings located in the basement of TRI’s University Centre. Feel free to read more about the exciting research conducted at CEAL and throughout TRI at this link.

Before taking a deeper dive into the project, here are some quick energy savings numbers:

  • Electricity Savings: 88,000 kWh
  • Cost Savings: $12,300
  • Payback: 1.8 years
  • Additional benefits: Reliability

The before and after photos below demonstrate how LED lights can improve performance while saving energy at the same time.

TWH Winter Free Cooling

Canada is usually associated with our long cold winter.  To take advantage of the cold weather, we go out for skating, skiing, snowshoe hiking, ice fishing, snowmobiling, etc., tons of fun activities.  Is there anything we can do at hospitals to make full use of the winter?  Actually there is.  Our hospitals have much essential medical equipment that requires cooling year around.  Magnetic resonance imaging (MRI) is one example.  It relies on deep cooling to maintain super-conductors inside to generate extremely strong magnetic field and radio waves to do very detailed scanning of patients.  The temperature required is so low for super-conductors that they are submerged in liquid helium, which is about -270 °C (-454 °F).

Don’t Stop Thinkin’ About Tomorrow – Talkin’ Trash New Year 2019

One of the great things about Homo sapiens is our ability to make whatever is happening to us right here, right now The. Most. Important. Thing. Ever.  Doesn’t matter if it’s a recreational hockey game for middle-aged (though still spry and youthful in appearance) Homo sapiens, waiting for one’s reusable travel mug to be filled with a free-range soypuccino, or a bunch of somewhat random Homo sapiens converging for the sole purpose of singing together…it’s the ability to prioritize what’s happening in the present above all else that sets people apart from the rest of this world’s inhabitants.

What you said: Good intentions in 2019

With the first month of 2019 still fresh as a honeycrisp apple, we’re checking in on your good intentions (kinda like New Year’s resolutions, but without the pressure). Of the 19 options, these really hit home with you.

12. Repair my appliances, clothes and stuff that’s broken

Not the handiest or craftiest? There are Repair Cafés throughout Toronto and around the world.

11. Join a Green Team

Well you’re in the right place 🙂

10. Walk and bike to work/errands more Continue reading
