There was a time when miles per gallon (MPG) meant nothing to most people. Today, every car advertisement seems to highlight MPG as a key feature. The MPG rating only moved the market because every vehicle has one. Consumers can ask, “What’s your MPG?” and compare like vehicles when making purchasing decisions. Similarly, states and cities worldwide hope that, one day, tenants will ask building owners “What’s your ENERGY STAR Rating?”
While approaches vary, the goal is the same: increase the efficiency of the
building stock by enabling the flow of information into the market and
encouraging the market to price energy efficiency.
