David Rodgers, Deputy
Assistant Secretary for Energy Efficiency , appeared before Congress to
discuss the potential for increased energy efficiency in new and
existing buildings to reduce greenhouse gas (GHG) emissions.
R&D Research for Market Deployment of Net-Zero Energy Buildings and Efficiency Technologies
DOE is conducting R&D in energy efficient technologies for
advanced solid-state lighting, for net-zero energy buildings and the
advanced components needed to achieve net-zero performance, in addition
to other building technologies that will be needed to achieve sustained
energy reductions. And we work with industry leaders and stakeholders
in coordinated support and investment, not only in R&D, but also in
accelerated market deployment of new efficiency technologies.
DOE's Building America Program
DOE's Building America program is conducting research through
competitively selected industry teams that work directly with leading
builders to develop and implement energy-saving construction practices
in new residential homes.
Current Building America prototype homes are
targeting energy savings of 40% or more than their predecessors, with
an ultimate goal of a 70% reduction.
When combined with renewable
energy technologies now in development, the goal is to achieve net zero
energy home performance capability in the five major climate zones in
the continental U.S. by 2020.
The progress being made in the Building
America program is the foundation for the Builder's Challenge already
discussed.
Goal of Net-zero Energy Commercial Buildings
by 2025.
In the commercial sector we are focusing our public-private
partnership efforts on achieving net-zero energy commercial buildings
by 2025.
Retail buildings in the United States account for
approximately 20% of commercial sector energy consumption and represent
the fastest growing subsector, making them an important opportunity for
savings.
Retailers Energy Alliance
In February 2008 we established the Retailers Energy Alliance
with companies such as WalMart, Whole Foods, McDonalds, Home Depot, and
many more.
To date, 23 companies with over two billion square feet of building
space have joined the alliance in order to share best practices, engage
equipment manufacturers in discussions of their common needs and to
eventually procure the products with the performance they want and
need. DOE is working to apply this model to a Commercial Real Estate
Alliance and an Institutional Buildings Alliance in the next twelve to
eighteen months. We will be reaching out to national accounts to
provide research technical assistance to those that want to improve the
efficiency of their existing portfolio of buildings by 30% while
developing new prototypes that save 50% or more over current code.
Energy
Independence and Security Act (EISA)
Our
current and planned activities are consistent with the Energy
Independence and Security Act (EISA) Commercial Buildings Initiative
provisions--Sections 421 (Commercial High-Performance Green Buildings) and Section 422 (Zero Net Energy Commercial Buildings Initiative).
If the (current) Retailer Alliance Members upgraded one third of their
existing buildings by 30% over the standard, then approximately 3
million metric tons of C02 would be avoided annually.
R&D for Technology Gaps in Equipment and Components
As we work with home building and commercial buildings industries we
are identifying technology gaps and improvement opportunities at the
equipment and component levels.
Solid-State Lighting
program: Cree, Inc.
The Department's Solid-State Lighting
program earlier this year announced up to $20.6 million in funding over
a number of years, subject to appropriation, for solid-state lighting
research and development.
Recent progress includes the cost-shared
research DOE conducted with Cree, Inc., a manufacturer of
semiconductors that enhance the value of light-emitting diode (LED)
solid-state lighting. Cree produced a high powered white light LED that
set a new record for brightness and efficacy. This is a great accomplishment as solid state lighting technologies
could potentially at least double the efficiency of today's general
lighting systems.
Based on the rapid progress made in the SSL industry,
in part with DOE support, in September 2007 DOE announced ENERGY STAR
criteria for 5 niche SSL products which become available on the market
on September 30th of this year. DOE has also announced its intention to
add more ENERGY STAR SSL products in 2009, sending a signal of expected
quality and performance to both consumers and industry.
R&D in Heating, Ventilation and Air Conditioning Equipment
In addition to lighting efficiency, we are pursuing advancements in
heating, ventilation, and air conditioning equipment; dynamic and
highly insulating window technologies; advanced building shell
materials and structures; solar heating and cooling equipment and
systems; and energy simulation and analysis software--all aligned to
achieving the goal of net-zero energy homes by 2020 and net-zero energy
commercial buildings by 2025.
These research and development activities provided the foundation
for continuous improvement in our building stock, and the potential to
contribute significant energy, cost and carbon savings to the economy.
