BEET-IT will focus on cutting building energy consumption. Structures now consume 40% of U.S. primary energy, that is, energy embodied in resources prior to undergoing any human-made conversions, and account for 40% of U.S. CO2 emissions. New, more efficient methods of cooling represent a great opportunity to reduce energy consumption and greenhouse gas emissions from buildings. Battelle Memorial Institute will research the absorption-osmosis cooling cycle and will develop a new air conditioning system that uses water as a refrigerant and salt as the heat absorber. The system uses reverse osmosis to efficiently separate water from the salt solution. This project will receive $400,000 in funding. These awards complete ARPA-E’s grants under its Recovery Act funding, which in three rounds since last year has selected 117 projects for $349 million in funding. See the DOE press release, the project selections (PDF 459 KB), the technical descriptions (PDF 545 KB), and the ARPA-E Web site.

The funding opportunity, administered by DOE’s State Energy Program, will also assist states in developing the necessary policy and program frameworks to stimulate investment in cost-effective, long-term energy efficiency deployments, especially in states that do not currently have aggressive energy savings goals in place.

In addition, for the very largest home water heaters, the new efficiency standards will for the first time require advanced technologies (heat pumps for electrically-powered products and condensing technology for gas products), paving the way for even bigger future savings.

“From washing hands to hot showers to clean dishes, we all rely on water heaters for our daily needs,” said Steven Nadel, Executive Director of the American Council for an Energy-Efficient Economy (ACEEE).”These new standards will deliver big national energy savings, reduce consumer energy bills, and cut pollution.”

According to DOE, for most product sizes sold, the new standards can be met with modest changes, such as adding more insulation to today’s conventional tank-style water heaters.For the most common size electric water heater (50 gallons), the standards will save 4 percent while for the most common size gas water heater (40 gallons), the new standards will save 3 percent.These per unit savings add up to big national impacts since more than nine million home water heaters are sold every year and water heating accounts for some 12 percent of the typical home’s energy use.

However, for the biggest products (those with over 55 gallons in storage capacity, which is about 9% and 4% of the electric and gas water heater markets, respectively), the new standards can only be met with heat pump and condensing technology.Heat pump electric water heaters save at least 50 percent and gas condensing water heaters save about 25 percent relative to today’s conventional storage water heaters.

“In the long run, a shift to electric heat pump and condensing gas water heaters is absolutely essential if we are to make deep cuts in household energy use and costs,” said Jeffrey Harris, Vice President, National Programs, of the Alliance to Save Energy. “DOE deserves tremendous credit for kick-starting this transition with its new standards.”

The new standards will save 2.6 quads of energy over 30 years or about enough energy to meet the total needs of about 13 million typical U.S. households for one year.Over the same period, consumers would save about $8.7 billion and carbon dioxide emissions would be cut by 154 million metric tons (an amount equal to the typical annual emissions of 30 million cars).

Based on DOE analyses, ACEEE estimates that a transition to electric heat pump and condensing gas products in all sizes and applications that make sense would save about 10 quads of energy and reduce carbon dioxide emissions by about 0.5 billion metric tons.

Last year, President Obama committed to accelerate DOE’s work to update many outmoded standards.These new standards are the latest in a series of more than 20 that must be completed during the current presidential term.

“Just a year into President Obama’s administration, DOE has made remarkable progress to update appliance standards,” said Andrew deLaski, Executive Director of the Appliance Standards Awareness Project (ASAP). “DOE’s new standards prove again that the cheapest and cleanest energy is the energy we save.”

Condensing and heat pump technologies are common in space heating but have only a toehold so far in the water heater market.More than 40 percent of U.S. furnace sales are of condensing products, and about 8 percent of U.S. homes are warmed with heat pumps.Several major water heater companies have brought these technologies to the water heater market and other major manufacturers are working to develop and introduce competing products.

“The Obama Administration has demonstrated again its strong commitment to an energy-efficient future with these standards.These standards are a big step toward improving the efficiency of U.S. homes,” said Tim Ballo, Associate Attorney for Earthjustice. “We are encouraged to see the Obama Administration make the right choice and give energy efficiency the boost that it deserves. We hope this decision signals the Administration’s future choices on energy efficiency standards, which have the ability to put money back in the American people’s pockets, spur innovation, create jobs, and lift our economy, while at the same time reducing harmful air pollution from power plants.”

A broad coalition of consumer, energy efficiency, and environmental groups as well as utilities, state officials, and more than 17,000 individuals wrote DOE urging adoption of the standards announced today.

Today’s final rule also updates minimum standards for less common products such as tankless water heaters (also known as instantaneous water heaters), pool heaters, and direct heating equipment, a type of space heater.

What are President Obama’s targets for GHG reductions?  Initially, the U.S. will pursue a 17% reduction below 2005 levels by 2020 (to put this goal in historic context, the modest Kyoto targets were 7% below 1990 levels).  This proposed target corresponds to the GHG limits contained in the climate change legislation passed by the U.S. House.  It is worth noting that the U.S. Senate is considering a bill that would set a more aggressive target of 20% below 2005 levels by 2020.  Long term, President Obama has a stated goal of an 83% reduction in GHG emissions by 2050.  These long-term goals have been incorporated into pending climate change legislation by targeting 30% below 2005 levels by 2025 and to 42% below 2005 levels by 2030 (the same year that the Department of Energy is targeting affordable zero energy homes for all Americans).

In addition to President Obama, several top White House officials and cabinet members are also expected to attend the Copenhagen conference, including Energy Secretary Steven Chu.  For the first time in history, the United States will establish a Center at the conference where top U.S. officials will deliver keynote speeches on energy efficiency and climate change.  In a sign of the times, the U.S. Department of State has established a “COP-15″ Facebook page and website to track the event.

See the White House press release, the COP-15 Web site, and COP-15 Facebook Page.

In a parallel move, the day after the White House announced U.S. GHG targets, China announced a reduction of the “carbon intensity” of its emissions by 40%-45% by 2020.  This measure of emissions, which differs from the U.S.’s emission measurements focuses on the amount of CO2 emissions per unit of GDP.  China’s measurement would mean that total GHG emissions in China would actually increase from today’s levels, but would result in far less GHG emissions than the expected increases associated with the rapid growth of the economy in China.  To achieve these binding goals, China will focus on research, development and commercialization of energy efficiency and renewable energy technologies and encourage low-carbon lifestyles.  In addition, China’s Premier will attend the Copenhagen conference.

DOE Webinar November 23—Greensburg: America’s Model Green Community in Their Own Words

November 12, 2009

The U.S. Department of Energy’s (DOE) Building Technologies Program is offering a webinar on Monday, November 23, 2009, from 1:00-2:30 p.m. EST titled “Greensburg: America’s Model Green Community in Their Own Words.”

This webinar will provide an overview of how Greensburg, Kansas, a town that was nearly destroyed by the largest tornado on record, found new life and purpose rebuilding as “America’s model green community.” Hear from city and government leaders how decisions were made to rebuild with the largest concentration of LEED^® certified buildings in the world, and where the town is headed today.

This webinar is geared toward federal agencies, state energy offices, renewable energy and energy efficiency associations, architects, residential and commercial builders, planning firms, and homeowners. The presenters will include:

• Bob Dixson, Mayor, City of Greensburg
• Kelly Estes, President, BTI-Greensburg John Deere Dealership
• Darin Headrick, Superintendant, Greensburg Schools District USD 422
• Daniel Wallach, Executive Director, Greensburg GreenTown

This webinar is free of charge, but you must register in advance to obtain a URL for the presentation and call-in phone number. Learn more about the webinar.

• Grocery Store (PDF 2.6 MB)
• Lodging (PDF 987 KB)
• Medium Office (PDF 1.2 MB)

These technical support documents were created by DOE national labs as part of the DOE’s Building Technologies Program.  These technical guides represent significant progress – especially when you consider that it was less than two years ago that the DOE launched its Net-Zero Energy Commercial Building Initiative, which seeks to achieve cost-effective net-zero commercial buildings by 2025.

In addition to including sets of energy upgrade recommendations, DOE’s  “how-to” guides (linked above), describe the assumptions, methodologies and analyses used to reach 50% energy reduction over ASHRAE Standard 90.1-2004 for each building sector addressed.  These technical support documents are meant to demonstrate how higher levels of energy performance can be achieved in commercial buildings.

Ed Pollock of the U.S. Department of Energy promotes the Builders Challenge alongside David Neiger and Laura Hutchings of Populus and Sean Smith of Sean Smith & Company (seen here in Builders Challenge-inspired t-shirts)

David Neiger, Principal at Populus Sustainable Design Consulting, led the EEBA conference tour through the high-performance energy features of the Wash Park duplex, which scored a 37 on the Builders Challenge E-Scale.  The E-Scale, which is a “miles per gallon” type rating for a home, is tied to the Home Energy Rating System Index Score, and denotes how the home performs compared to a typical home built to code.  A home must score below a 70 on the Builders Challenge E-Scale to be eligible for certification under the Department of Energy’s program.  In addition, the Builders Challenge program requires the implementation of greenbuilding best practices which address indoor air quality and durability management.

Following the Builders Challenge Tour, the Populus team joined Ed Pollock, Sean Smith, Eric Doub of Ecofutures and Tom Wade of Artistic Homes at a panel discussion focusing on zero energy homes and the goals of the Builders Challenge / Building America program.  Mr. Pollock began the panel presentation by discussing the Department of Energy’s Builders Challenge goal of an affordable zero energy home (or “Net Zero”) for all Americans by the year 2030.  In order to achieve these substantial increases in residential energy efficiency, it is essential that the building industry highlight the operational savings of a zero energy home, rather than merely focusing on the first costs of high-performance home features.

David Neiger of Populus presents to a group of industry professionals at the Department of Energy Builders Challenge EEBA Conference Home Tour

To date, the Builders Challenge program has certified a total of 1800 homes, with six homes scoring net zero or better on the E-Scale and with an average E-Scale score of 63.  While this represents only a tiny fraction of the homes built in the United States each year, the high-performance energy features of these 1800 homes results in an average cost savings of $1.6 million per year.

If you are a builder, developer or architect and would like to learn how you can pursue Builders Challenge certification for your next project, contact Populus Sustainable Design Consulting, a Partner in the Builders Challenge program, and we’ll walk you through the program requirements and the steps to certification.  Unlike some green home certification programs, there is no fee for registering your project in the Builders Challenge program, although there are costs associated with the third-party verification and energy rating that is required under the program.  In some cases, building an above-code performing home can qualify you for substantial rebates, incentives or tax credits.
