Building America Roadmap

to High Performance Homes

Eric Werling Building America Coordinator Denver, CO April 29, 2013

Building Technology Office U.S. Department of Energy

EEREs National Mission

Mission: To create American leadership in the global transition to a clean energy economy

1) High-Impact Research, Development, and Demonstration to Make Clean Energy as Affordable and Convenient as Traditional Forms of Energy

2) Breaking Down Barriers to Market Entry

Why It Matters to America

Winning the most important global economic development race of the 21st century

Creating jobs through American innovation Enhancing energy security by reducing our

dependence on foreign oil and gas Saving money by cutting energy costs for

American families and businesses Protecting health & safety by mitigating the

impact of energy production on air quality and climate


High Impact in Everything We Do

The 5 EERE Core Questions: 1. HIGH IMPACT: Is this a high-impact problem? 2. ADDITIONALITY: Will the EERE funding make a large difference

relative to what the private sector (or other funding entities) are already doing?

3. OPENNESS: Have we made sure to focus on the broad problem we are trying to solve and be open to new ideas, new approaches, and new performers?

4. ENDURING U.S. ECONOMIC BENEFIT: How will this EERE funding result in enduring economic benefit to the United States?

5. PROPER GOVERNMENT ROLE: Why is what we are doing a proper high-impact role of government vs. something best left to the private sector to address on its own?

Building America Business Case Home Energy Economic ImpactN3

~$2,200: Average Annual Household Energy Bill >113,000,000: DOE Housing Units in America >$240 Billion: Amount spent on home utility bills per year.

if we make our houses 50% more efficient >$120 Billion: Available to the economy


N3 Benefit Discussion

= 1100 x 116 million x 0.1 = $1276000000

If 1% of homes reach this level of energy consumption reduciton each year, then something around a benefit of $63 to $1 (consumer savings vs funding, need to account for cost of improvements as well) NCI, 1/24/2013

Building America Business Case High-Performance Home Opportunity

100 Million Homes: Jobs (millions of U.S. housing jobs) Energy Independence (NZE

Homes use No foreign energy)

Clean Air & Healthier Households (we spend >60% indoors)
