Such an absurd comment.  Actually, this will directly benefit affordable projects, because they will pass the savings onto residents, just as occurs with lower utility bills due to conservation.  As for discouragement of larger projects: silly.  The cost increment is so modest per square foot, and the cost benefit so clear, that it will not impede the decision to appropriately scale.

Suggesting this is racist is silliest of all.  Environmental benefit benefits all.  Environmental Equity's a thing, focusing on the obligation of all to provide healthy conditions for all, particularly those most disenfranchised.

But mostly: look at the economics.  This is an unambiguous step forward.
