UHN Energy and Environment Delivers Improved Lighting to TGH Loading Dock

Sometimes a lighting project is about more than just improving energy efficiency. The loading dock at TGH is a busy place with lots of activity and many vehicles coming and going at all hours. The previous lighting was old and inefficient and the light levels were starting to become a safety issue. Staff were recommended to not walk on the floor level and to always wear reflective vests as safety precautions. Continue reading

Co-op Tales from UHN

Hi everyone! My name is Alondra Garcia, a fourth-year student at the University of Toronto in the Environmental Sciences program, and for the last four months I was the sustainability intern here at UHN. As the saying goes, all good things must come to an end and so does my placement here. Before saying my goodbye, I’d like to tell you a little Continue reading

Climate Change is a Health Care Issue

A lack of progress in reducing emissions and building adaptive capacity threatens both human lives and the viability of the national health systems they depend on, with the potential to disrupt core public health infrastructure and overwhelm health services.

This is not a quote from Greenpeace, Al Gore, or David Suzuki. It is from The Lancet, one of the most prestigious medical journals in the world. More and more health organizations are recognizing climate change as the biggest global health threat of the 21st century. Canadian health organizations, such as the Canadian Medical Association, Canadian Association of Physicians for the Environment, Registered Nurses’ Association of Ontario, and others are urging decisive action from political and business leaders, institutions, and individuals to reign in CO2 emissions that are causing climate change.

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.

The Sixth Sensor – I See Live People!

Looks like I might be starting a trend referencing old 90’s movies on the Talkin’ Trash blog. This time, with Halloween fast approaching, we are taking a spookier turn as we look at the recent stairwell lighting project at TRI University Centre.

UHN: A Medical Innovator, But Also An Energy Innovator

My previous blog described a unique energy conservation project at UHN’s Princess Margaret Cancer Research Tower (PMCRT). With innovative contaminant sensing technology, we were able to convert our research lab exhaust system from constant flow to variable flow, which significantly decreased loading on the exhaust fan motors. As described in the blog, this change produced a reduction in electricity peak demand (kW) of 38.5% and reduction in overall annual electricity consumption (kWh) of 42.7%.

We thought this was a Continue reading
