AET Group Inc. (AET) is an environmental consulting, auditing and scientific services firm founded in 1998. Their head office in Kitchener is in a 135-year-old former farmhouse. They have remodeled it to rival some of the leading buildings built today in terms of its energy and water efficiency. LED lighting, and a planned addition of a ‘living wall’ to improve indoor air quality are among the many features that are or will soon be integrated into the building. As part of their work, AET is often asked to provide stormwater impact monitoring and water quality assessments. With this project, AET has taken the plunge to address stormwater problems on their own property.
