Before I left for the airport, I decided to check out the Canadian Centre for Architecture. I was mainly visiting to see 1973: Sorry, out of gas, an exhibition about changes in architecture due to the 1973 gas crisis. The gas crisis provoked changes in how houses were designed by creating a need for more energy-efficient insulation, heating, and cooling. It was fascinating to see some of the home designs of that period, from houses underground and using wind power on the top of apartment buildings. It was also interesting to see what ideas had come into the mainstream, such as simply providing a house with good insulation.
No photos were allowed inside the building, and I wish I had more time to see all of the other exhibits.
