Houston Weatherization Is Production Scale Efficiency
By LESLIE EATON
The Wall Street Journal
HOUSTON — President Barack Obama wants to make a million houses a year more energy efficient as part of his goal to create thousands of “green” jobs and reduce U.S. carbon emissions.
But the administration’s push to expand an obscure antipoverty program into a centerpiece of that initiative is stirring debate over the best way to use a flash flood of federal stimulus dollars.
City contractors measure windows for screens that block sunlight and prevent it from heating up the room.
Texas is slated to get $327 million over the next two years to help cut poor families’ utility bills by “weatherizing” their homes. Nonprofit groups affiliated with the federal Weatherization Assistance Program are set to get a big funding boost and say they are up to the task.
But Texas and some other states don’t want simply to supersize existing programs and are also proposing what they say are more efficient ways to use the stimulus money. Indiana and Missouri are asking nonprofit groups to compete for some or all of the funds; Wisconsin plans to use some of its allocation to tackle low-income apartment buildings and is hoping to dedicate $10 million toward replacing appliances.
Texas, for its part, plans to give $94 million directly to cities so they can start their own programs, like a neighborhood-based one the city of Houston now runs. Started in 2005 after Hurricane Katrina hit energy producers and sent electricity costs soaring, the program picks a low-income neighborhood of old houses and tries to sign up as many homeowners as possible.
Workers then move from house to house, doing a quick evaluation and using measures that can be completed in hours. Issa Dadoush, director of the city’s general-services department, said the typical homeowner’s energy use drops by as much as 20% in the steamy summer months, helping to save, on average, $335 over six months; with the stimulus money, the city says it can weatherize 10,000 homes a year.
“The assembly-line approach gives us more bang for the buck,” Mr. Dadoush said. Houston would get $23.4 million of Texas’s stimulus funds for this program, which is now run by money from taxes and a local utility.
By comparison, Sheltering Arms Senior Services, a Houston charity, would get $22.2 million over two years, way above its funding of $350,000 last year. The charity says it could weatherize as many as 3,500 houses a year, 10 times the current number, under new rules that allow it to spend as much as $6,500 on each house, up from about $3,000.
Sheltering Arms typically performs an “energy audit” that figures out which improvements are the most cost-effective ways to cut energy use. But like other traditional weatherizing groups, it often combines such efforts with major home repairs, using money from a variety of sources such as United Way donations.
So it might repair a damaged roof or foundation in addition to caulking windows and replacing a refrigerator, in a process that can take days and require repeated visits. Customers’ energy savings after such repairs are difficult to quantify, state officials said; customers save an average estimated $413 a year, nationally, after traditional weatherization.
Watchdog groups are warning the flood of stimulus money into weatherization programs could lead to money being lost, wasted, siphoned off or simply left unused. “It’s a prescription for absolute disaster,” said Leslie K. Paige, media director for Citizens Against Government Waste, an antitax group in Washington.
Community agencies say the money will be well-spent. “Everything is at stake in this,” said David Bradley, executive director of the National Community Action Foundation in Washington, which advocates for these groups and for the more-comprehensive weatherization approach.
The U.S. Department of Energy says it is willing to consider nontraditional programs; Gil Sperling, who manages the federal weatherization program, plans to visit Houston soon to see how they city’s effort stacks up.
The benefits — and limitations — of the city’s method could be seen one hot May morning at the home of Alex and Carolina Cisneros in the Kashmere Gardens neighborhood. The little white house leaked about twice as much air as it should have, said Joseph DeLeon, a contractor for the city program. After testing the house, he pinpointed the main source of the problem — cracks between the walls and ceiling in the bathroom.
In less than two hours, he and a colleague weather-sealed doors, caulked around windows and plumbing fixtures and replaced light bulbs. But they couldn’t install insulation; the ceilings weren’t strong enough.
Unlike the nonprofit, which might have tackled a costly ceiling repair, the city program moved on to the next house.
That was good enough for Mr. Cisneros. “It’s cooler already,” he said.

Profile of a One Stop Shop: Neighborhood Energy Connection
The Neighborhood Energy Connection (NEC) is a Saint Paul-based nonprofit organization that provides energy conservation information, services and programs to residents, businesses, and communities across Minnesota. Their stated mission is to reduce pollution, conserve resources, and improve quality of life by offering tools for energy-efficient living. Visit The NEC at http://www.thenec.org
Installed Efficiency Measures
The Neighborhood Energy Connection brings energy efficiency to Saint Paul homeowners with its Home Energy Squads, skilled crews that delivered installed measures in one low cost visit.
An NEC Home Energy Squad will visits homes and recommends energy-saving measures. Home owners choose which improvements to make, and the Squad installs them on the spot. Home owners pay for the materials, but installation costs are free.
Choices include exterior door weather stripping, “smart” power strips, programmable thermostats, compact fluorescent lighting, water-saving shower heads and faucet aerators, and insulating water heater blankets.
Outreach and Education
Neighborhood organizations are teaming up to offer a residential energy efficiency program to Saint Paul residents. The first step is to attend a free workshop on saving energy and money in the home. Next, they schedule a home visit where the Home Energy Squad will install the energy-saving materials for only a $30 co-pay. Finally, we provide one year of personalized home energy reporting.
In order to qualify for the $30 co-pay for the home visit, residents must attend the free neighborhood home energy workshop.

Obama’s Green Jobs Road Tour Visits Smart Grid Tech Company
President Obama continued to promote his jobs push and green economy goals during a press conference Friday from Opower, a smart-grid software company in Arlington, VA. He went on to announce that he has signed the latest jobs bill to extend unemployment benefits and offer tax breaks to employers who hire unemployed workers. Opower expects to hire 100 new employees this year.
Opower software helps consumers track energy use so they can mange home energy use by giving them a dashboard of energy use data. He related Opower’s work to the proposed Home Star program to spur job growth as home owners have homes upgraded with energy efficiency measures.
“The country that leads in clean energy today will lead the global economy tomorrow” said Mr. Obama. “Lets see if we can replicate Opower’s sucess across the country.”

Rocky Mountain Institute Builds on Retrofit Success
Empire State Building a Blueprint for Success in Retrofit
Colorado based Rocky Mountain Institute has won the Sustainable Building Industry Council’s ”Beyond Green High Performance Building Award” for the retrofit of the Empire State Buildingthe Empire State Building retrofit. “As our nation pursues strategies that allow us to use our natural resources more efficiently, a focus on high-performance buildings is a must,” SBIC Executive Director Bud DeFlaviis stated. “Rocky Mountain Institute and their partners have demonstrated the role that retrofits will play in this effort. Their work will undoubtedly help inspire other forward-thinking building practitioners who are creating a new generation of buildings that are mindful of the people they serve and the environment they impact.”
Goal: RetroFit to all Commercial Buildings by 2050
This award comes as RMI launches a new initiative, RetroFit. Building off both the success and lessons learned from the Empire State Building project, this initiative–which will be funded in large part by philanthropy–aims to encourage the retrofit of the entire U.S. commercial building stock to use, on average, 50 percent less energy by 2050.
Retrofitting the World’s Most Famous Office Building
A year after RMI and partners completed a retrofit design of the Empire State Building, many other large commercial properties are lining up to follow in its footsteps. (Watch video)
Building on our success with the Empire State Building, RMI is taking retrofits to an even deeper level, finding ways to achieve bigger energy savings faster and applying them to a greater number and wider variety of building types. Under this new initiative, called RetroFitTM, RMI hopes to spur the retrofit of at least 500 buildings within five years. Beyond that, RMI are designing additional projects with an even higher goal-to initiate a process that will encourage the retrofit of the entire U.S. commercial building stock to use, on average, 50 percent less energy by 2050.
Approach
RMI will work with building or portfolio owners who control and influence large amounts of commercial real estate to test new approaches to “deeper and cheaper” retrofits in their own building. RMI also plan to work with a select group of “service providers” (design teams, property managers, and ESCOs) to develop the skills and service packages required to deliver the potential level of energy savings that retrofits need to achieve at scale.
RMI is currently identifying partners for the following additional projects:
Project to Portfolio
A franchise business presents opportunities for developing a replicable model of energy efficiency retrofits across a portfolio of similar building types, such as car dealerships, supermarkets or box retail. Through our analysis and audit process, retrofits are standardized, making each building retrofit faster and cheaper. retrofits.
Package Retrofits
Sometimes a few basic measures create deep savings. This project approach takes a set of measures and applies them repeatedly to a number of commercial buildings with similar characteristics.
This approach is specifically useful for a commonly underserved retrofit-smaller buildings with individual ownership patterns. This can fruitfully be combined with utility demand-side incentive programs to address financing barriers.
Optimizing ESCOs
The purpose of this project is to re-vamp the way energy service companies operate to include whole systems design for much greater energy savings (>50 percent) in ‘ripe’ buildings. The project encourages more transparent contractual guidance to ensure industry reputation and owner value. This “service provider” enhancement project has the potential to greatly enhance the quantity, quality and ability in the market to provide deep, cost effective building retrofits.

WSJ Reports on Boulder’s Green Efforts
Wall Street Journal reports on Boulder’s struggle to achieve climate action goals:
as Congress considers how to encourage Americans to conserve more energy, Boulder stands as a cautionary tale about the limits of good intentions.
“What we’ve found is that for the vast majority of people, it’s exceedingly difficult to get them to do much of anything,” says Kevin Doran, a senior research fellow at the University of Colorado at Boulder.

Berkeley Energy Efficiency Standard for Home Sales
City of Berkeley, California, Population 104,000
Project Began 1987; ordinance revised in 1991
Annual CO2 Reductions of 5,098 tons
Annual Financial Savings $450, depending on household size
Initial Investment Subsidized: $1,000Without subsidy: $3,400
Project Status 600 dwellings transferred or remodeled annually
SUMMARY
A city mandate/ordinance requiring that all households meet certain building standards when they are sold, transferred or renovated. This city-wide ordinance with various specific measures has reduced residential energy consumption by over 13 percent, annually reduced CO2 emissions by over 5,000 tons and allowed households to save up to $450 US dollars on their energy bills.
WHAT IS IT?
RECO, Residential Energy Conservation Ordinance, is a city law which mandates that all residences (homes, apartment buildings or mixed use buildings) sold, transferred from one proprietor to another, or renovated exceeding a total permit value of $50,000 must comply with certain energy and water efficiency requirements.
These requirements meet or exceed California’s Title 24 Energy Codes, which are also mandatory but are only in effect when properties are remodeled. RECO covers conditions of sale and transfer, and has an immediate effect on household energy consumption.
The intent of the ordinance is to assist residents in reducing their energy bills while achieving an overall reduction in energy consumption. There is evidence that this is working. The City of Berkeley has lower overall energy consumption per capita than other regions of California. California has the lowest energy consumption per capita in the United States.

Zero Down Solar Leasing Available to Colorado Home Owners
by Mark Jaffe
The Denver Post
Bert and Kendra Prospero were interested in putting solar panels on their home ? until they learned the upfront costs could be $35,000.
Last week, however, they had a large solar array installed on their Boulder home ? for $1,000.
The Prosperos are the first Coloradans to become solar-array leasers ? a financing technique that industry executives and analysts say will drastically expand the number of homes with solar energy.
“People think solar is expensive, but with leasing it’s a no-brainer ? it’s free,” said Mark Simmons, vice president of Vibrant Solar, one of the companies offering solar leases in Colorado.
The Prosperos are leasing a 9-kilowatt system from San Francisco-based SunRun, the country’s oldest solar-leasing company.
The family will pay about $90 a month for the system under a 20-year lease, and it should be able to generate all the electricity they need.
Their current Xcel Energy bills are $100 to $120 a month, Bert Prospero said.
SunRun owns and services the array on the Prospero home and even monitors its performance from its San Francisco headquarters, said SunRun president Lynn Jurich.
“Financing is one hurdle, but knowing what kind of system to put on is another, and maintenance is a third. Leasing addresses all three,” Jurich said.
In Highlands Ranch, John Smith has signed up for a 5.6-kilowatt system from SolarCity, a Foster City, Calif.-based leaser, opening an operation in Colorado in March.
Among the things Smith said he liked about SolarCity was a shorter lease of 15 years.
“I felt it gave a little more savings and flexibility,” Smith said.
Smith, who estimates he’ll save 20 percent on his electricity bills, is paying nothing down for his system. SunRun and Vibrant Solar, a Denver solar-leasing firm, also offer zero-down systems
Even though systems can cost $35,000, a homeowner gets most of that back in tax
credits, depreciation allowances and utility rebates.
The solar leasers harvest those benefits for investors, who can use the tax credits. They use the money to install the home solar arrays and make money on the lease payments, depreciation and utility rebates.
“Most families don’t want to own a solar array; they just want solar power,” said Jason Coughlin, an analyst at the National Renewable Energy Laboratory in Golden.
A homeowner with a lease who sells the house usually assigns the lease to the buyer or buys the system and sells it as part of the property.
“It’s a great thing to generate your own electricity,” Kendra Prospero said. “And it makes you more mindful of what you are doing in your house.”

Energy efficiency experiences, best practices and resources from program managers
Washington, D.C., February 2, 2010
New Interactive Web Resource Brings Added Energy Efficiency Program Support to Public Power Utilities at http://cleanefficientenergy.org
This new web resource, launched this week by the Clean and Efficient Energy Program (CEEP), encourages the sharing of experiences, best practices and educational resources among energy efficiency program managers at public power utilities. CEEP’s online community allows stakeholders to learn about and discuss aspects of energy efficiency program design, implementation and evaluation, while making connections with peers and energy efficiency experts.
CEEP, a nationwide initiative with a mission to promote and support the energy efficiency efforts of locally-owned utilities, is a partnership of the Alliance to Save Energy (the Alliance), the American Public Power Association (APPA), and the Large Public Power Council (LPPC).
Missy Mandell, LPPC’s Executive Director, points to the importance of energy efficiency as part of a utility’s resource plan stating “with demand outpacing supply, costs rising, and environmental concerns mounting, public power utilities face a number of challenges in securing affordable, reliable, and clean energy. Energy efficiency is one of the most constructive, cost-effective ways to address these challenges.”
The new web platform includes a comprehensive resource library where users can easily access decades’ worth of advice, how-to guidance and case studies, researched by and gathered from public and private sector leaders. Through ratings and comments, the user community can be actively involved in defining best practice strategies. CEEP frequently adds new materials to the site, however users are also encouraged to upload resources that they find helpful and to share information about their own successes and challenges.
In addition, users can seek or offer advice in CEEP’s discussion forums by joining an ongoing conversation or starting a new discussion thread. Overtime, CEEP will increasingly become a product of its users as it captures more and more information based on real world experiences.
APPA CEO & President Mark Crisson adds that “APPA seeks to offer a wide variety of education, policy and advocacy resources and services to help public power utilities promote energy efficiency. CEEP compliments Energy Efficiency Resource Central (www.eercnet.org), public power’s effort to provide resources on energy efficiency, by linking our members to guidance developed by dozens of energy efficiency advocacy organizations.”
Jan Schori, former general manager for the Sacramento Municipal Utility District, chairs the CEEP Steering Committee, which is comprised of fellow public power leaders. Schori comments, “There are 2,010 public power utilities in the U.S., accounting for 16 percent of all electricity sales. Many are leaders in energy efficiency - CEEP’s online community will help utilities that are just starting out or exploring new areas to find strategies that have already been field-tested and proven by their peers.”
The unveiling of cleanefficientenergy.org coincides with Clean Energy Week (February 1 - 5), an initiative of the Alliance to Save Energy and nearly 80 other organizations (www.cleanenergyweek.org). Alliance President Kateri Callahan notes, “The new CEEP website could not have come at a better time. This resource embodies many of the goals of our Clean Energy Week partners: to engender dialogue, to showcase proven best practices, and to advance energy efficiency.”
The Clean and Efficient Energy Program (CEEP) was initiated in 2009, as a joint-effort of the Alliance to Save Energy, American Pubic Power Association, and Large Public Power Council. CEEP is funded by support from the Sea Change Foundation and the U.S. Environmental Protection Agency.
