Energy Benchmarking

When applied to building energy use, benchmarking can provide a mechanism for measuring how efficiently a building uses energy relative to the same building over time, other similar buildings, or modeled simulations of a building built to code or a desired standard. Building energy use is typically measured in energy use per square foot (ft 2 ). To make comparison even easier, buildings can also be rated against predetermined scales that can provide a single rating or score, taking into account variations in building operating characteristics, climate, or other factors. By making energy performance information readily available, disclosure of such ratings can facilitate market transformation toward more energy-efficient buildings.
