Why should businesses care about energy efficiency in buildings? Why should companies put their staff effort and limited budget resources into documenting, analyzing, and reducing their energy use? This report provides a multidimensional, in-depth look at the business case for energy efficiency in buildings. Its core is the firsthand commentary of executives at three real estate companies, each at the leading edge of efficiency and sustainability in its respective sector (high-profile commercial adaptive reuse, medical buildings, and multifamily residential). 

For real-time, and instant information on a building’s energy performance, an Energy Management Information System (EMIS) is a sound investment. EMIS can lower a building’s energy use by up to 20 percent, yielding quick payback, smart operations, and better buildings.

Data quality is important when communicating publicly about the energy usage of buildings, as it plays an integral role in a city’s ability to measure, track, and report progress in meeting energy, sustainability, climate, or other public goals.
