Calculate Envelope Air Tightness with New Tool

A new tool developed at Oak Ridge National Laboratory (ORNL) now addresses one of the most overlooked energy issues facing commercial buildings: building envelope air tightness. The laboratory’s new web-based energy savings calculator now offers FMs and other building professionals the ability to see firsthand how envelope improvements might be able to reduce costs in their particular facilities. The calculator, which was developed in conjunction with the Air Barrier Association of America and the National Institute of Standards and Technology, looks particularly at the practice of introducing air barrier systems into buildings, as air leaks can significantly harm energy efficiency.…
