BECP periodically assesses the impacts of its activities by estimating historical and projected energy savings, consumer savings, and avoided emissions. Since the inception of the Program 20 years ago, cumulative full-fuel-cycle (FFC) energy savings from 1992- 2012 are estimated to be approximately 4.2 quads and cost savings to consumers have been more than $44 billion. These savings have resulted primarily from the Program's activities which upgrade the model energy codes, accelerate their adoption by states and localities, and improve code compliance by means of various software tools and other types of training and technical support. The federal budgetary cost of the Program over this same period (1992-2012) was estimated to be around $110 million, resulting in a ratio of more than $400 in cost savings for each DOE program dollar spent.
The estimated cumulative benefits from the Program through 2040 are also significant. The cumulative energy savings attributed to the Program total nearly 46 quads of FFC energy in 2040, or 44 quads of primary energy, equivalent to almost an entire year’s worth of primary energy consumption from the U.S. residential and commercial sectors at current consumption rates. The Program is estimated to save consumers up to $230 billion on their utility bills by 2040. Annual carbon savings reach 36 million tons at the end of 2012, and the cumulative savings by 2040 are estimated at 3,478 million tons. View the report detailing these results .
In recent years, the DOE's Building Energy Codes Program (BECP) has achieved substantial savings through active participation in code development processes, and in supporting increased adoption and compliance with building energy codes and standards. Some of these achievements include:
- Providing the International Code Council (ICC) with significant input for the International Energy Conservation Code (IECC) Commercial Energy Efficiency chapter.
- Coordinating with ASHRAE to streamline commercial building energy standards and formalized development cycle.
- Supporting ASHRAE to increase commercial building energy efficiency standards by 30% between 2004-2010.
- Working within the ICC code development process to develop 30% more efficient residential building standards between 2006-2012.
