Mike at Home: The Sequel

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!

Smart Thermostat

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.

You down with DCV at KDT? Yeah you know me!

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

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

Next in our list of exciting energy endeavors, this blog will discuss huge savings realized by a retrofit to the laboratory exhaust system at the Princess Margaret Cancer Research Tower (PMCRT). The lab exhaust system has been converted from constant speed to demand controlled to ensure more efficient operation. I’ll get into all the super interesting details below, but the best part is the savings so I’ll start off with that. Continue reading
