Good news spreads fast and so do good ideas. That’s what seems to be happening in the arena of Building Energy Benchmarking. At least 21 major cities have launched a required reporting process for building owners of various sizes. It seems to be way modern Mayors are able to prove their “Green”. Smart, in this era of rising energy rates and concern over pollution, benchmarking serves as a Win x 4 solution without too much trouble from building owners. It was piloted in NY City where 3,600 buildings over 50,000 sq feet required reporting of their energy and water usage.
