Tallest solar-sided building in North America under construction in Halifax - The Weather Network
Does the exterior of your old building need a retrofit? Why not replace the walls with something that actually generates power, like solar panels. That's exactly what St. Mary's University is doing at their Loyola residence and it's about to break a record for how tall it is.

"It'll definitely provide power to the university and it'll lower our carbon footprint which is also very important too," Gillis added.
He explained that the panels will generate about 100,000 kilowatt hours per year with a carbon reduction in the range of 15 to 20 cars a year off the road.
Electrical engineering students at the university have also been monitoring the project first-hand as the construction progresses.
