The Eastgate office building in Edmonton is colorful, bright, energy efficient and oh yeah, has a 153 kilowatt solar system on the roof. The building, which will soon become an outpost for Environment Canada, was a developer led project that was seeking LEED Gold status. In order to get the necessary energy efficiency points they went with the simplest, cheapest, most cost effective technology - solar power. This is just the start as solar continues to get cheaper and cheaper.
