Meta Report: A Search for Deep Energy Savings

A new report from NEEA's BetterBricks program and New Buildings Institute investigates* eleven examples of energy retrofits in existing commercial buildings that, on average, resulted in energy use 50% less than the national average – many with an energy use intensity (EUI) below 40 kBtus per square foot.  The report provides an in-depth review of 11 of these buildings, looking at building characteristics, efficiency measures, motivations, money, measured energy performance, market and tenant outcomes, and barriers and innovations. Results from an initial search which found 50 buildings with 30% or more savings are also included.
