Perhaps LEED should be replaced by a bunch of smaller certifications, each covering only a tiny subset.
It is nice to have one logo you can stick on a building, instead of lots of them. But after a little pushing it could be normalized to have a spot for multiple plaques near the entrance of a building, showing which certs it has earned.
Then you have a lower bar for entry and owners can choose a la carte what they want to strive for, and disregard the rest.
Like, a sound isolation rating on an apartment building would be a huge selling point. Have a certifying company that brings in big speakers and microphones and tests room-to-room sound conduction. Then you get a certification for the soundproofing.
I guess the nice thing about private cert authorities is anybody can just do this. It would take a while to get recognized but you could solve the two-sided marketplace problem pretty easily.
