Hello everyone,
If you work in a high rise office tower, chances are that not much consideration was taken for thermal performance, energy efficiency or even the comfort of employees in regards to sound and natural lighting.
Most of Alberta's downtown building stock was built in the 60s and 70s and they are showing their age. Reimagine is an initiative by Edmonton based architectural firm Manasc Isaac, that aims to transform existing buildings into healthy, sustainable buildings. With plenty of retrofit potential in Alberta it only makes sense. Retrofits are not cheap but when done correctly the potential is immense.
This past week I had the pleasure of attending an event put on by Reimagine in Edmonton. Billed as a Tower Renewal Summit the keynote speaker was architect Sarah Beardsley. She’s responsible for the massive retrofit of the Sears (sorry, Willis) Tower in Chicago. A project still in the planning stages the cost is estimated to be between $200 to $300 million dollars. A not insigificant price tag but the Willis Tower is the tallest building in the western hemisphere. You can read more about it here, it’s quite an impressive project.
They're also putting a green roof up on the 90th floor. It's so high up that only mountain vegetation will grow up there. However the green roof isn't what's doing the heavy lifting energy wise. Replacing the windows and addressing the building envelope will carry the mail in that regard. With better daylighting and less need for large, expensive heating and cooling systems the cost savings will be as massive as the tower.The building was completed as Sears Tower in 1973, the heyday of energy ignorance, which means the skyscraper has single-pane windows that leak around the edges and let in hot air in summer and cold in winter, lights everywhere and inefficient electric heating throughout.
"Each old window is like a car driving around," Beardsley said. "And people don't think of it that way it's just a window. But I think maybe we need to start thinking about it that way."
For an energy efficiency geek like me this is crack. I recommend you head to Reimagine’s website and check out their thermal scans of existing buildings in Edmonton and their reimaginings. Something to keep in mind the next time someone complains about the office temperature/air conditioning/loud fan.
