Thank you both.
Back in mid-2015 or the fall of 2015 when I moved into this role, we didn't have a lot of data and evidence around all of our facilities. We received some program integrity funding in budget 2016 that allowed us to actually study our facilities and do things that I mentioned like Energy Star ratings on those facilities.
The way we used to make investments in our facilities was largely based on health and safety issues, addressing issues where we were outside of code. Some of the targets that my colleague Nick Xenos mentioned are actually allowing us to start looking at greening infrastructure targets as well.
I have a couple of small examples. You'll remember that not long ago LED lights were fairly expensive, etc., but over time they've become easier for us to purchase. Just doing small refits in lighting allows us to accomplish a 6% reduction in overall GHG across the infrastructure. The cost-benefit associated with that is shown in the ROIs, which are about seven years for those various investments, and the savings in electricity.
Another small example would be some of the smart building technology that we've been piloting and installing. I mentioned that we have 66 buildings that are done and we're going to 100 facilities by the end of this year. Our initial pilots allowed us to save about 15% on our energy bills, and the ROI on some of those investments is about five years.
Those are some of the things we are doing. We're tracking and costing, and the methodology is available to the Chair.
