#1 in MUSH!

We’ve often joked about acronym bingo, what with all the BRBs, IMOs and OMGs, but have you heard of MUSH? Not the bowl full in Goodnight Moon, but Municipalities, Universities, Schools and Hospitals … that MUSH.

Turns out this is a pretty important category when it comes to energy, since we are Continue reading

Stopping To Smell The (Energy Saving) Roses – An Operation TLC Celebration

When it comes to saving energy, it’s easy to get so focused on how far we need to go to meet our targets and goals that we forget to take a look back to see how far we’ve come.  Case in point – this past April, UHN set new, aggressive energy saving targets, replacing our original, aggressive energy saving targets that we hadn’t fully met.  And I was so intent in figuring out how well we were doing against our new targets that it wasn’t until last month that I realized that, albeit 6 months later than we’d planned..

We’re meeting our original energy consumption saving target!

This is something all at UHN should celebrate – it truly is a team effort in every sense of the word.  So, before we return to new targets and projects, take the time to pat yourself on the back and reflect for a moment, not on where we’re going, but how far we’ve come…we’ve done something good!

Shut the Sash: The Power of Pizza

Armit Dhinsa - the sash man

Armit – the sash man

Hi, my name is Armit Dhinsa; I am a co-op student from Waterloo who has been leading the Shut the Sash program from January 2016. For those of you in research at UHN, you have probably seen me wandering around the lab spaces for some time now, wondering how I magically appear out of nowhere almost everyday. It is all the the Shut the Sash campaign, a major energy saving behavior change program in Research.

The importance of Shutting the Sash was new to me when I joined. As a biology student who uses fume hoods regularly at school, the extremely high energy usage of the Fume hood was completely unknown to me. Continue reading

AC Motors, VFDs, and Energy Savings at Toronto General Hospital

I’d like to share two recent energy projects at Toronto General Hospital, which used VFDs to achieve significant energy savings and improve control.  When I say significant I mean that the savings could buy a house, well maybe not a house in Toronto.  There is also a fairly technical explanations of motors and variable frequency drives but I’ll leave that to the end for obvious reasons.

Little Choices for Little Futures

Being a new Dad has given me a lot to think about, but you probably already knew that. Like in this picture perhaps. I used to just put on a jacket and go outside, now….. I make a hundred decisions before I go out the door. “Stroller or carrier? Is she warm enough, can she breathe, is she still breathing, do we have the diaper bag, are there actually diapers in the diaper bag, how long will we be gone, wait where are we going?”.  Those are my immediate concerns, but what about the future?  What about long term?

What about in 30 years when my daughter is my age?  (insert nervous gulp here)
