Co-authored by Jim Kelsey and David Jump. We’ve shown leadership but now it feels like we’re stumbling. We’ve been pretty optimistic about normalized metered energy consumption (NMEC) as a streamlined platform for achieving and demonstrating savings in buildings (see our prior post for more on why). And,...
