A very cool website put out by researchers at the UofC: (for parts of NW / SW Calgary anyways)

Calgarians may have barely stirred in their sleep one spring night in 2012 as a small-engine plane flew back and forth over the city’s neighbourhoods at low altitude.
A team of researchers at the University of Calgary used the images and city data to create a web-based map that shows potential greenhouse gas emissions for entire suburbs and pinpoints hot spots in each individual home where waste energy is escaping.

Very cool - you can click on your house and see the imaging for it:
My house wasn't scanned, but I'm curious to hear if other CP'ers here have had their house scanned and if it correlates to known leaks in their house (coughranchlandsellingcough....)
Here's the interesting part:

Homes in older neighbourhoods like Dalhousie and Brentwood score relatively well compared to those in some newer subdivisions like Patterson and Westgate.
Part of that difference may reflect the fact that the heat loss index weights for the larger living areas and stricter building code in effect at the time those subdivisions were developed, but Hay said it may also point to the fact that some new homes are not as well built as they’re billed.
“The results give me pause because my home is one of those,” he said.
“It’s cold and my heating bills are high, despite the fact that I invested a lot in buying something that I thought was energy efficient.”

So if your house was built in the 70's it apparently stands a better chance of being built better than your typical house built int the 80s or 90s.
Some comments on the Herald article question the time of the flight - the issue whether solar load could have influenced the results but I'm going to assume they've taken that into consideration when they timed the flight.
