In January of 2013 the International Energy Conservation Code with the City of Chattanooga Amendments became mandatory, requiring diagnostic testing be performed by a Certified Duct and Envelope Tightness (DET) Verifier. This includes testing for duct and building envelope leaking and addresses how renovations to existing homes and duct systems could better benefit residences in limiting air infiltration and cutting excess energy spending .
