Using Sound to Detect Air Infiltration in Buildings

by Alison Kibe

Since 2013, the US Office of Energy Efficiency & Renewable Energy (EERE) has been funding research at the Argonne National Laboratory and the Illinois Institute of Technology to develop technology that uses sound to detect and quantify air infiltration in homes and buildings. If you imagine that it is the dead of winter and you’re staring at a hole on the side of your home, the chance you decide that something ought to be done about it is probably high. Air infiltration caused by air leaks and poor insulation is a problem that can reduce the building efficiency and as a result raise heating and cooling bills. What many people don’t realize is that all of the small gaps in windows, walls, and doors can add up to a sizable opening. Given their small size, they may go unnoticed unless tested for.
