Buildings are responsible for roughly 40% of greenhouse gas emissions. Here's how homes can become energy-positive and save money on utilities.
A Norwegian company called Powerhouse designed the world’s northernmost energy-positive building. Completed in 2019, Powerhouse Brattørkaia will reportedly generate more energy than it used during its lifetime, including that used during its construction and demolition. The building uses solar panels, geothermal wells, and heat recovery systems to reportedly generate approximately 485k kilowatt hours annually.
Some home builders are transitioning to ‘zero net energy’ in order to keep up with the green energy transition. And it doesn't have to cost an arm and a leg. Bruce Sullivan, the technical director for Zero Energy Project, explains how.
