When Ontario is giving out free smart thermostats, you know it’s time for a blog! Most of my recent blog posts have been about projects at UHN, so this time I’m going to change it up and talk about a couple of neat technologies I’m using at my apartment to save energy. Both of these savings ideas were mentioned in my previous Mike at Home Blog, but these new technologies really help to put those ideas into practice in a convenient way. There are many ways to save energy at home, even if you are a renter like me!
I already had a programmable thermostat which was helping to save energy, but I wasn’t able to maximize savings for a couple of reasons. One way I typically try to save power is by setting back the thermostat if I’m away for a weekend or longer vacation, however this often led to an uncomfortably cold temperature for a few hours upon return. When energy savings lead to discomfort it can be difficult to maintain the energy savings behavior and I may have been less consistent in doing the temperature set back as a result. With my old thermostat on the fritz, I took the opportunity to upgrade to a web-connected thermostat.
Whether you want to send a car to space or implement an energy project, you must measure and track results! One of the biggest things we do here at the Energy and Environment team is to measure and track project results because it gives us real world information that we can use to accurately evaluate similar projects in the future. This post is about the recently completed demand controlled ventilation (DCV) project at the Krembil Discovery Tower (KDT). This project follows in the footsteps of similar projects that we worked on with UHN Research at the Princess Margaret Cancer Research Tower (PMCRT). Since we had such good proof of concept results from PMCRT, it made for a much easier decision to proceed with the project at KDT. Let’s take a look at the project and results!
Here’s a preview of the savings for those that don’t have time for all the details:
- Electricity Demand Savings: 310.6 kW (equivalent to about 630 window AC units)
- Electricity Consumption Savings: 1,433,353 kWh (equivalent to 161 typical Canadian houses annual consumption)
- Natural Gas Savings: 418,343 cubic meters (794 tons of CO2, equivalent to taking 169 cars off the road)
- Utility Cost Savings: $241,337
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.

There is no better time of year than now to ride your bike to work (or to the gym, or to the grocery store, or just for fun)! Fresh crisp air and cool morning temperatures help to ensure you won’t end up a sweaty mess on arrival. Biking regularly can help you get in shape, feel better, improve your health, and it’s just plain fun! Check out this TED Talk about the awesome ways that biking can change you.
I’ve been meaning to write a blog on biking ever since the large expansion of Toronto’s Bike Share system this summer. Continue reading
I never thought such huge savings would be possible from a replacement of a ten year old computer system, but here we are. Normally when I think of energy savings opportunities, I think of HVAC equipment replacements, Variable Speed Drive installations, improvements to control sequences, lighting upgrades, and even electric vehicles. So, when I spoke to a company that said we could achieve big savings by upgrading computer infrastructure I was intrigued.
Now that we are groggily emerging from our hibernation of sitting on the couch in a Snuggie and binge TV watching while eating cookie dough ice cream, it’s time to think about spring cleaning. On second thought, sweeping the garage, sorting old junk, and throwing mittens in a drawer sounds awful – let’s talk about spring greening instead! Here are a few tips for an energy efficient spring and summer: Continue reading
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
