This is sort of dragging up an ancient topic, but curious how your firms are currently addressing accreditation (LEED AP, WELL AP, LFA, etc.). There was a time when we were all talking about this, and a number of firms instituted requirements, but it has been a long time, and I'm curious how it's looking now in 2024. Thanks!
