We are happy to announce that Ballard Aperture achieved a blower door test rating of 2.5 Air Changes per Hour which is well below the Northwest Energy Star Standards. Along with other requirements such as High efficiency lighting, High efficiency Heating and Cooling and High efficiency appliances such as the dishwasher and water heaters the project has officially been Energy Star Certified!
