A Search for Deep Energy Savings
Report / August 23, 2011 / Building Innovation
A report from NEEA's BetterBricks program and New Buildings Institute investigates* 11 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 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.
*With support from the Doris Duke Charitable Foundation and The Kresge Foundation
Presented at the 2012 ACEEE Summer Study on Energy Efficiency in Buildings.
A Search for Deep Energy Savings
New Buildings Institute and the National Trust for Historic Preservation hosted a Deep Energy Savings in Existing Buildings Summit in Boulder, Colorado, September 14-16, 2011. The event convened 80 national experts in critical aspects of energy efficiency. The summit was a working meeting aimed at defining the framework and tools needed to support much more aggressive levels of efficiency in the existing commercial building marketplace. This report summarizes the key discussion areas and recommendations.
