EP275 The Sound of Better Buildings with Kieren McCord (May 2026)
About this episode
Bill Spohn interviews Kieren McCord about the intersection of acoustics, indoor air quality, and building performance upgrades.
Quotes from the episode: "The tighter your envelope, the more attention you have to pay to ventilation and indoor air quality." "The acoustics of the ordinary rarely gets attention." "There's so much good work being done, so much data being collected, and oftentimes it doesn't leave the hard drive." "Noise annoyance may be one of the things people are most passionate about." In this episode of the Building HVAC Science Podcast, Bill Spohn welcomes Kieren McCord, a research scientist at Pacific Northwest National Laboratory, for a conversation about indoor environmental quality, acoustic comfort, and the often-overlooked benefits of building performance upgrades. Kieren shares her path from music and acoustics to building science, explaining how sound, comfort, air quality, thermal resilience, and human perception intersect in homes. The conversation explores how energy upgrades such as better windows, tighter envelopes, and improved insulation can create benefits beyond lower utility bills. Kieren explains how acoustic performance is measured, why low-frequency sound is difficult to block, how decibel weightings like dBA and dBZ work, and why human response to noise can be highly…
