‘Cash for Caulkers’ Would Provide Rebates for Energy-Efficient Building Products, Retrofits

Wednesday, March 3rd, 2010

President Obama announced March 2 details on “Homestar,” a Cash for Clunkers-like rebate program designed to entice Americans to make their houses more energy efficient. The administration hopes the incentives will boost demand for building products such as insulation, efficient windows, and roofing in the same way car sales skyrocketed last year when consumers were offered rebates for trading in their gas-guzzling autos for more fuel-friendly models.

As outlined in the proposal, dubbed “Cash for Caulkers,” homeowners could be eligible for up to $3,000 in point-of-sale rebates for purchases of efficient product upgrades or whole-house audits/retrofits. Energy efficiency contractors and suppliers would market the rebates, provide them directly to consumers, and then be reimbursed by the federal government.

Under the first level of rebates, Silver Star, consumers would be eligible for up to $1,500 for a variety of home upgrades, including adding insulation, sealing leaky ducts, and replacing inefficient water heaters, HVAC units, windows, roofing, and doors. There would be a maximum rebate of $3,000 per home.

The more comprehensive Gold Star level would provide a $3,000 rebate to consumers for a whole-house energy audit and subsequent retrofit tailored to achieve a 20% energy savings. Additional rebates would be available for savings above 20%.

Administration officials are still working with Congress on details, including how long the program will run, but the White House expects Homestar to create “tens of thousands” of jobs, cut energy bills for families by $200 to $500 per year, and reduce the nation’s dependence on oil.

In a statement, the NAHB acknowledged the program’s economic possibilities: “This has the potential to be a real shot in the arm for the home building industry,” said association chairman Bob Jones. “It will help put America back to work, and it will help families save on monthly energy bills.”

Masco Home Services president Larry Laseter, one of three manufacturers who joined Obama at the event, urged Congress to approve the program. “We applaud the efforts of the administration to introduce a jobs creations program that is truly a win-win-win,” said Laseter. “The Homestar program will put our nation’s skilled construction force back to work, benefit homeowners through comfort and energy-efficient improvements to their existing homes, and result in long term energy efficiency gains.”

The National Lumber and Building Material Dealers Association was more cautious, telling Building Products’ sister publication ProSales it will be working closely with the White House, the DOE, and Congress to help ensure the program does not put small and large independent dealers at a disadvantage versus big-box retailers. The NAHB also expressed that equal access for all will be essential to the program’s success.

Greener Windows at a Nicer Price

Wednesday, January 6th, 2010

High-performance windows could become more affordable for builders and homeowners by mid-year if a Department of Energy (DOE) effort to lower costs goes as planned.

DOE is initiating a volume purchase program for R-5 and low-E storm windows, hoping that the effort will level the playing field for small builders who, until now, have found such specs prohibitively expensive. By catalyzing a virtual marketplace, the federal agency hopes to amass greater demand for high-performance windows, thus enabling high-end window manufacturers to reduce their per-unit operating costs.

Anticipated customers include home builders, contractors, and remodelers, as well as academia, local governments, nonprofits, individual homeowners, and other groups focusing on weatherization and green retrofits.

The ultimate goal, of course, is to improve the overall energy efficiency of the nation’s housing stock. Funded through DOE’s annual EERE/Building Technologies program, the volume purchase initiative will raise the bar on Energy Star standards, which require a minimum R-value of 3. Agency officials note that raising the R-value of a home’s windows from 3 to 5 can reduce heat loss by as much as 40%, reducing monthly energy bills for the homeowner as well as the home’s carbon footprint.

In mid-December, the DOE issued an RFP to window manufacturers to submit proposals for program participation. Products accepted under the program will receive a DOE seal of approval and will be listed in an online directory of qualified manufacturers.

The first phase of approved windows at reduced prices is expected to become available in spring 2010.

DOE has set minimum order guidelines at 15 for retrofits and 20 for new construction. However, participating window manufacturers may choose to offer purchases in smaller quantities at their discretion. Minimum totals may be reached with any combination of window types and sizes available through the program.

Excel Announces New Products, Services for Its Custom Modular Homes

Monday, September 21st, 2009

Excel Homes, a modular builder of custom and stock designs, came to Hanley Wood last week to discuss new delivery and green programs, as well as cover why conventional stick-frame builders should consider modular construction.

Modular home building is especially relevant during this downturn in housing, says Steve Scharnhorst, president and CEO of the company. Excel homes are built in a controlled factory environment using advanced framing techniques, which means less waste, material costs, and opportunity for damage, such as from weather, he says, and modular homes also are built quicker than traditional houses. Materials savings also comes from the bulk product purchases Excel is able to make versus a small custom builder. This adds up to 10% to 30% less total cost than a stick-built residence, he says.

Taking these factors into account, builders can “do more with less dollars,” Scharnhorst says. Instead of building 10 stick homes, they can produce 20 modular homes, he explains.

The company also recently announced it can now handle the set process of delivering its modular homes. This entails delivering the home modules and setting them on the foundation. Builders who choose to use this option will get a 10-year warranty against structural defects.

Green builders can take advantage of Excel’s green home options. The company offers Energy Star-qualified homes, and will launch other green options in the future that meet NAHB and ICC green standards.

In Excel’s Energy Star program, an energy rater will meet with builders to review bueprints and make changes to ensure compliance. The home also will undergo inspection at the manufacturing site and on-site testing for the final product to ensure buildings meet Energy Star qualifications.

In addition to the designs featured on Excel’s site, the company’s new Drawing Board blog showcases some of the more innovative ideas it’s working on or trying out and welcomes reader feedback to help determine which options will move forward.–Victoria Markovitz

Fluke Tools’ New Thermal Imager Boasts High Resolution, Easy Operation

Friday, September 18th, 2009

f-tir32_c_54a_cWith energy audits in demand, stimulus money flowing, and homeowners clamoring for tighter homes that save money, now could be just the right time to invest in the tools that can make testing your homes much easier. One such device that came through our office this week is Fluke Tools’ TiR32 Thermal Imager, an impressive option launching this month.

Like previous iterations, the TiR32 features “IR-Fusion,” which allows users to integrate a digital image with a thermal image, including a picture-in-picture view that makes it simple to identify exactly where problem spots are. On top of existing features, this new model adds what the company claims is the industry’s first 320×240 sensor, which provides a crisp, clear view; optional telephoto and wide-angle lenses can be attached.

Once images are captured on a flash card, the integration of infrared and digital images carries over to the included SmartView reporting software, another difference versus most comparable models, according to the company.

“We’ve take highly complex systems and turn them into very simple, easy-to-use tools,” Lincoln Howell, Fluke’s marketing manager for thermography, told Hanley Wood editors.

Indeed, even I, a person who sits behind a desk all day, found the tool simple and straightforward to use. What’s more, the tool’s rugged design (reps say it will survive a 6 1/2-foot drop) means contractors can carry it with confidence on the jobsite.

Though $9,000 may seem like a hefty sum to drop, Fluke reps claim imagers with comparable resolution can range upwards of $15,000 or more; its ability to find problem areas faster—and to find more of them—than lower priced models also is a key selling point, they say.

Fluke offers an array of training on its Web site, covering both tool use and topics such as thermography and electrical safety, as well as in-person training. The company also has an online forum, Test Tool Talk, with discussions on a range of testing tools and tasks.—Katy Tomasulo<–>

White Paper Explains How to Integrate Propane Backup Systems Into Renewable Energy Setups

Thursday, August 27th, 2009

The Propane Education & Research Council (PERC) released the white paper Propane-Enhanced Renewable Energy Systems, a 36-page document that describes why and how contractors should implement supplemental propane backup for their renewable energy systems.

Even the most robust alternative energy systems are bound to face some downtimes over their lifetime, whether from cloudy days, fluctuating ground temperatures, or other interruptions. “Nearly all renewable energy sources, when expected to provide the same comfort and convenience modern Americans now enjoy, must be supplemented with efficient and environmentally respectful forms of conventional energy,” the paper asserts.

With thorough descriptions and helpful schematics, the document runs through some of the most common renewable energy setups—including solar hot water, photovoltaics, and air-source heat pumps—and explains how to integrate a propane backup system.

John Siegenthaler, engineer and heating specialist and the paper’s author, told Hanley Wood editors that 90% of the hardware used in these systems is hardware installers are already used to using.

The white paper is available for download on PERC’s Web site. –Katy Tomasulo

Environmental Building News Decries Polystyrene Insulation

Tuesday, August 4th, 2009

In the article “Polystyrene Insulation: Does It Belong in a Green Building?” Environmental Building News executive editor Alex Wilson says there’s enough health and environmental evidence to suggest that the answer is “No.”

“All insulation materials are green on one level because they play a huge role in reducing building energy consumption,” Wilson says, but adds that polystyrene insulation may not be the best choice.

Wilson, a long-time green building advocate and a nominee for the 2009 Hanley Award for Vision and Leadership in Sustainable Housing, describes various issues with polystyrene insulation and recommends alternatives be used when doing so will not compromise a building’s energy performance.

The editor of the well-regarded EBN monthly newsletter says that polystyrene is produced from toxic chemicals–benzene, which is a known human carcinogen, and styrene, which is considered an endocrine disruptor, asthma inducer, and possible carcinogen. In addition, all polystyrene building insulation–extruded (XPS) and expanded (EPS)–contains the brominated flame retardant HBCD, which European agencies have labeled an organic pollutant and a bioaccumulative toxin. The EBN article says that despite significant effort, manufacturers have been unable to find a flame-retardant substitute.

“Polystyrene is the least green of common insulation materials,” Wilson writes in the article, which outlines alternative materials. He recommends rigid mineral wool, which he says performs well on exterior foundation walls and is being used beneath concrete slabs in Europe.

 “Polystyrene Insulation: Does it Belong in a Green Building?” was published in the August 2009 issue of Environmental Building News. You must be an EBN subscriber to read the entire story at www.buildinggreen.com.

Generac Product Development Includes Generator Aimed at Off-Grid Homes

Tuesday, June 16th, 2009
Representatives from generator manufacturer Generac visited our offices yesterday.  The company recently re-entered the portable generator market with two models, and last month unveiled its latest units, the mid-level XG and the IX inverter generator.

In addition, the company is testing a new standby model designed specifically for off-grid homes. Unlike emergency systems, which sit idle until a natural disaster knocks out power, generators for off-grid homes may be called upon more frequently due to the occasional unreliability of wind or solar power. As such, the generators must be more durable, longer lasting, and quieter. For more information on this 6-kW offering, check out this case study from the Propane Education & Research Council.

Clement Feng, Generac’s executive vice president and chief marketing officer, said about 2 percent of single-family homes have backup generators, while more than 10 percent have portable models. He noted that the biggest change over the past few years has been a significant drop in price across the industry. The company’s 8-kW model, for example, can be found for as little as $2,000, compared to roughly 10 times that a decade ago. –Katy Tomasulo

The six generators in the XG Series offer a compact size for easy transport. High-performance engineering, a three- to four-times longer life, oversized full-wrap frame tubing, impact-resistant corners, and heavy-duty wheels help the units stand up to the rigors of the jobsite.

Cooler Roofs

Monday, June 8th, 2009

While it’s easy for homeowners to love the benefits of green products, most aren’t willing to sacrifice style in exchange for saving the planet.  That conundrum applies to cool roofs, which save energy by reflecting heat, but sometimes come in lighter colors than homeowners desire.

Now, some manufacturers boast cool roofs that come in darker hues.

For example, Owens Corning says its Duration Series shingles line of Premium Cool roof shingles come in brighter and richer colors than would normally be expected of a cool roof.

Certainteed remarks that the color palette of its Landmark Solaris cool roof shingles include richer browns and darker greys than traditional selections.

Custom-Bilt Metals uses technology developed by BASF to bring darker colors to its shingles with Ultra-Cool coatings.

Have any darker cool roofs caught your eye? What do you think of the products? Let me know at vmarkovitz@hanleywood.com. –Victoria Markovitz

Owens Corning says its Duration cool roof shingles are richer than traditional offerings.

Roxul Brings Its Stone Wool Insulation to U.S.

Wednesday, June 3rd, 2009

roxul_installRepresentatives from insulation manufacturer Roxul, the North American arm of Denmark-based Rockwool International, visited our offices June 2 to announce the availability of Safe’n’Sound and ComfortBatt stone wool products in the U.S. market.

Previously available only in Canada, Safe’n’Sound (interior walls) and ComfortBatt (exterior walls) are made with stone wool, a combination of basalt rock and recycled slag. Both are fire resistant and non-combustible, able to withstand temperatures up to 2,150 degrees F, the manufacturer claims. The material also does not absorb water or hold moisture, so it will not rot, corrode, or contribute to bacteria growth, according to the company. In addition, the material’s density and multi-directional structure contribute to sound absorption and, for ComfortBatt, R-values of R-15 in 2×4 construction and R-23 in 2×6 construction.

roxul_cuttingFinally, the material cuts easily with a serrated blade (we tried it ourselves), so it’s easy to install around electrical boxes, plumbing, wires, and other obstructions.

For more information, visit www.roxul.com; the site will relaunch June 15 with new videos showcasing the insulation’s fire resistance and other properties. –Katy Tomasulo

SRS Energy Introduces Curved-Roof BIPV

Tuesday, May 12th, 2009

srs-energy_2At the AIA conference last week, SRS Energy unveiled its Solé Power Tiles, what the company calls the industry’s first building-integrated photovoltaic product designed specifically for curved roof systems. The barrel-style tiles install alongside US Tile’s traditional clay tiles (about 15% of the roof will comprise Solé), blending seamlessly to allow for the collection of solar energy without interfering with the roofline’s aesthetics. The product, which is comprised of Uni-Solar flexible solar cells, provides 500 watts per 100 square feet. SRS says the Power Tiles are lighter weight than their ceramic counterparts, install like traditional roofing, and are tested for durability, UV stability, color fastness, and wind resistance.
