Robert Bean, FASHRAE – Adam Muggleton – The Edifice Complex Hosts & Radio Joe Team Up to Solve the Worlds IAQ & Building Science Problems

Air Date: 6-10-2022|Episode 666

This week we have a little change of pace for our audience. We are playing back a new show that Radio Joe recorded recently with the hosts of the Edifice Complex Podcast, Robert Bean and Adam Muggleton. It was a wide ranging show on the podcasting, IAQ, building science and disaster restoration. We may not have solved all the world’s problems but we did at least start to define what’s needed. This thought provoking show with two worldly Canadians, one of whom is a transplant from the UK, was entertaining and informative. It was a broad discussion about the past, present and future of the built environment. Radio Joe will be on live to answer questions during the playback.
