In May, the Green Building Alliance awarded a $20,000 Innovation grant to EcoBuilt Efficient Buildings, a Pennsylvania-based company that specializes in energy audits. EcoBuilt and Drexel University will use that money over a 12-month period to determine whether a greener alternative to conventional masonry blocks called MaqCrete—which EcoBuilt’s principal, Dennis Crook, has been developing for the better part of three decades—can be mass-produced cost effectively.

The 60-year-old Crook, who runs the company with his wife Siti, is no Johnny-come-lately to the world of efficient construction. His first job in the early 1970s was with an insulation and home improvement company in Newton, Iowa, where his father was an industrial engineer for Maytag. “One of the lessons he taught me is that there’s always a cheaper and better way to do things.”

In 1985, Crook bought an abandoned steam plant in the Overbrook Farms district of Philadelphia, and after years of remediation turned it into a seven-unit housing development that qualified for energy-efficient certification under Owens Corning’s “Thermal-Crafted Homes” program. More recently, his company built a duplex with two 1,680-square-foot homes in Lancaster, Pa., whose HERs were, respectively, 69 and 71.

Crook is a big proponent of improving a home’s thermal package through better construction techniques and materials. MaqCrete’s formula, which received a 20-year patent in 2002, consists of post-industrial waste and/or bio-based plant fibers mixed with Portland cement, but uses about 25 percent less cement than a conventional masonry unit. MaqCrete is 30 percent lighter than masonry block, with an R-23 insulation value. And it’s fibrous, so screws have something to grip onto.

“What’s revolutionary,” says Crook, “is that the product can serve as a whole building system. It’s fire-resistant, non-rotting, and users can attach other products to it,” which would also reduce labor costs.

But Crook hasn’t gotten MaqCrete past the prototype stage, and his latest challenge has been figuring out which binder combination will work best. Enter Drexel.

Dr. Michel Barsoum, a professor in the university’s department of materials science and engineering, says MaqCrete’s commercial fate lies in its meeting or exceeding performance criteria for concrete and cement that have become ingrained over centuries. Barsoum’s own research team has been working for two years on an alternative concrete product made from blast-furnace slag, and what’s kept it from passing ASTM’s C1157 performance standard is that it sets five minutes quicker than conventional cement.

Remodelers Snatch Up Free Reclaimed Products

Thursday, March 10th, 2011

Two remodelers shared how they recycled others’ trash into creative solutions for their green remodels during a recent Webinar for GreenExpo365.com–free products they would have missed if they weren’t on the lookout for opportunities.

Builder Matt Belcher of Belcher Homes in St. Louis saw the city tearing down a repossessed house next to the one he was remodeling. The 100-year-old hand-cut limestone blocks stocking the foundation caught his eye.

“They were going to demolish and haul all that stuff off,” said Belcher. “We convinced the city to leave the stones behind so we could use them to terrace the yard with. You can’t find better landscape materials.”

And in Pheonix, Ariz., the pavers leading to the doorway of one of Philip Beere’s renovated projects were scored out of the driveway Beere, of Green Street Development, demolished during the renovation. – Evelyn Royer

Architecture 2030 Launches Building Product Carbon-Reduction Initiative

Tuesday, February 15th, 2011

Architecture 2030 has announced one of its most ambitious initiatives to date–launching the 2030 Challenge for Products and setting in motion the organization’s push for a 50% reduction in the carbon footprint of building materials by the year 2030.

“The raw resource extraction, manufacturing, construction, usage, and end-of-life stages of building products each generate significant greenhouse gas (GHG) emissions,” says Architecture 2030 founder Edward Mazria. “Slowing the growth rate of GHG emissions and then reversing it is the key to addressing climate change.”

In 2006 Mazria became one the earliest experts from within the industry to identify the impact of the building sector on increased carbon emissions when he established Architecture 2030 and set forth its mission to make new buildings and major renovations carbon neutral by 2030. Since then he has become one of the strongest voices calling the industry to action against climate change and pointing to the crucial role we must play in facing this critical crisis. As the next step in those efforts, Mazria, who received the 2009 Hanley Award for Vision and Leadership in Sustainable Housing, is now calling on manufacturers to voluntarily adopt the goals of the 2030 Challenge for Products–and for building professionals to begin specifying low-carbon products that meet the Challenge’s targets.

CARBON FOOTPRINT TARGETS
The 2030 Challenge for Products aims to reduce the carbon footprint of building materials by targeting greenhouse gas emissions resulting from manufacturing and transportation. The targets will be phased-in over the next 19 years: setting carbon reduction goals of 30% over the next two years, 35% by 2015, 40% by 2020, 45% by 2025, and 50% by 2030, a similar approach to the way incremental goals were set out by the organization when it launched its 2030 Challenge for building performance.

Architecture 2030 calls the next two years the “development period” during which product category benchmarks and standards will be established. The benchmarks will set the category average base levels from which reductions will be measured. Until these are in place, manufacturers can measure the carbon-equivalent footprints of their products using ISO 14000 Standards or the World Resource Institute’s Greenhouse Gas Protocol Scope III and Product Life Cycle Standards for carbon footprints.

The 2030 Challenge for Products is not a certification program, and Architecture 2030 will not be certifying products. Instead, it will maintain a database of manufacturers who have adopted the Challenge, committed to its targets, and conducted and published life cycle assessments (LCAs), even during the two-year development period.

“Once standards and benchmarks have been developed, the beauty of the Challenge should kick in,” says Mazria. “So while the Challenge is voluntary, we are exploring ways to establish the benchmarks, and hope manufacturers will follow specific and transparent methods in conduct their LCAs. Eventually we would like to see complete Environmental Performance Declarations and third-party verification, but everyone must work toward creating standards, developing data, and generating increased demand from the design community.”

Dealer Groups Help Launch Product Verification Program

Tuesday, January 18th, 2011

A group of regional building material supplier associations joined with the Intertek product testing and certification company Thursday to launch the Claim Check Verification Program, an independent program designed to ensure that manufacturers can back up their product claims.

Claim Check’s most important founders, who used the International Builders’ Show in Orlando, Fla., as the launching pad for the third-party program, said their venture owes its birth to concerns over greenwashing and the potential legal liabilities caused by Chinese drywall, as well as to builders’ ages-old reluctance to try new products.

Claim Check “gives the whole [supply] chain an added level of confidence,” Mark Menzer, Intertek’s vice president of association affairs and programs development, told reporters.

“This gives the builder a chance to check all the claims about a product,” added Bill Tucker, president of the Florida Building Material Association and organizer of the Building Products Retailers Alliance (BPRA), the driving force behind Claim Check. BPRA’s seven member associations represent building material dealers in 22 states. Intertek has facilities worldwide, “so if there’s a claim coming from anywhere, our partners can check it at the source,” he added.

Here’s how Claim Check works:

  • –A manufacturer would go to www.claimcheckverified.com, sign in, and create a profile.
  • –The manufacturer then would upload supporting information that it believes backs up the qualities it’s claiming for its products.
  • –Intertek—which bills itself as a worldwide network of more than 1,000 laboratories and offices and more than 26,000 people in 100+ countries—then would use its expertise to judge the validity of the manufacturer’s assertions. Intertek staff will review the data supporting the claim; whether the data was generated by an accredited, third-party laboratory; whether the data is fresh; and whether the claims fulfill internationally recognized standards, such as ISO.
  • –Products verified through Claim Check will be listed in a directory, and manufacturers can state in their literature that a product’s claims have been Claim Check verified.
  • –Other manufacturers have the right to challenge a Claim Check, thus helping police the program.
  • –A manufacturer that signs up for the program must pay a $500 application fee and then a minimum $2,000 evaluation fee per product; Menzer said he expects most evaluations to cost no more than that. There is an annual $500 listing fee per manufacturer and a $1,000 follow-up charge imposed every two years to cover the costs of determining whether the product has changed since it first was verified.

There is no cost to builders, dealers, or consumers.

Initially, Claim Check will verify doors, windows, “critical structure products,” siding, decking, chemical wood preservatives, and roofing products, its sponsors said.

Tucker said that building material dealers worked to create Claim Check because so many companies were making suspect claims about the green qualities of their products that builders, homeowners, and dealers all were finding it difficult to verify what the manufacturers were advertising.

Meanwhile, he said, homeowners in Florida and other parts of the country discovered that exceptionally high levels of hydrogen sulfide in drywall imported from China was damaging homes and endangering lives. That led to a number of liability suits against the manufacturers. Early last year, Tucker said Florida dealers feared their state’s implied warranty law–which Tucker says most states have–might render dealers legally liable for defective products or for green products whose performance didn’t match up to their claims. FBMA’s lawyer warned Tucker as much.

The National Lumber and Building Material Dealers Association (NLBMDA) has sought for years to protect dealers from getting entangled in such issues by urging Congress to pass legislation known as the Innocent Sellers Fairness Act. But that campaign has won scant support in Congress in recent years, and NLBMDA invested little effort promoting the issue in the Democrat-controlled Congress over the past two years.

Through Claim Check and Intertek, dealers will get “a source that would stand with them if there is a claim,” Tucker said Thursday. –Craig L. Webb

Hidden Healthy-Home Benefits in High-End Appliances

Wednesday, July 21st, 2010

When we think about appliances as they relate to green homes, we tend to consider the energy and water savings from dishwashers, refrigerators, and washing machines, or about the inherent indoor air quality benefits of range hoods and bath fans.

But some appliances go even further, representatives from German appliance maker Miele tell ebuild, with special cycles, improved engineering, and add-on options that provide a host of bonus attributes that can take a healthy-built home to the next level.

Here are a few examples of additional features Miele says are worth considering when specifying appliances:

Dishwashers: Water must be hot enough to kill germs, so models with sanitizing-wash programs provide an additional option for loads with items like baby bottles or cutting boards. Miele’s units also feature the “CleanAir” drying system, which circulates air around an outer chamber for drying, rather than pulling in room air into the clean cavity.

Washing machines:

–Like dishwashers, consider units with a sanitization setting for those items that need special hygienic care. Miele also offers a “sensitive” option, which adds an additional rinse for those users who cannot have any detergent residue or fragrance on their clothes for health reasons.

–It takes 2,900 gallons of water to manufacture a pair of jeans; 766 gallons to make one cotton T-shirt. This means that washers, particularly front-loaders that are more gentle on clothes and therefore help them last longer, don’t just save homeowners money, they conserve water from manufacturing.

Stainless steel: New versions of stainless steel engineered to resist fingerprints and smudging mean simple wet-rag cleanup instead of using smelly, slimy stainless steel cleaners.

Steam ovens: These units are growing in popularity both for their speed and their health benefits—foods can be cooked without oils or sauces and vegetables retain more vitamins and minerals than traditional cooking methods.

Ventilation: Select hoods that ventilate to the outside.

Vacuum cleaners: Though these are typically an aftermarket product, the company suggests offering a HEPA-outfitted model as a move-in gift to homeowners, ensuring the healthy-built home isn’t tarnished by the swirling microscopic particulates that can be stirred up by lesser-quality vacs. But even all HEPA models aren’t created equal, so compare the filtration statistics before committing to a unit.

Appliances with these higher-end features often cost more, but their durability and expanded options are attributes that frugal buyers are latching on to. “Builder grade” has become synonymous with “cheap,” says Miele’s director of public relations Paul McCormack. “Customers are getting back into a 1950s mentality,” he says. “No longer do they want disposable items.” –Katy Tomasulo

American Hometec, A.O. Smith, and Rheem Unveil New Efficient Water Heater Offerings

Thursday, April 29th, 2010
American Hometec C-10

American Hometec C10

For green-built homes and remodels, high-efficiency water heaters are one of the most common upgrades, especially in light of recent tax and rebate incentives. Most of the time, this means going tankless, but lately also has included a new crop of high-efficiency “hybrid” tank models. In recent weeks, several new technologies landed on our desks.

American Hometec is touting the coil-less technology of its new C10 electric tankless water heater. The first of its kind in the U.S., according to the company, the technology heats water indirectly with quartz tubes; because electric components are not in direct contact with the water, lime-scale buildup is eliminated, according to the firm, increasing durability and helping to maintain the unit’s 95% to 98% efficiency over the long-term.

Three capacity settings—4.2 kW, 6.4 kW, and 8.5 kW—allow one unit to accommodate multiple needs; it has a rise of .4 – 1.3 gpm. The C10 is the first in a line of coil-less electric and Energy Star-certified gas models that will be rolled out this year.

A.O. Smith Voltex

A.O. Smith Voltex

Manufacturer A.O. Smith entered the hybrid water heater market this week with the introduction of Voltex. Similar to recently introduced hybrid technologies from GE and Rheem, Voltex uses heat pump technology to pull heat from the air and transfer it to water in the tank. It has three operating mode to accommodate varying levels of demand. The Energy Star-rated electric unit uses half the energy of a standard tank-type heater, the company says.

Rheem HP-50 and HP-40

Rheem HP-50 and HP-40

Finally, Rheem, which introduced a 50-gallon hybrid water heater last year, expanded its offerings with the HP-40, a 40-gallon model aimed at smaller households with low hot-water demand. The Energy Star-rated unit has an energy factor of 2.0, more than twice the efficiency of a traditional storage unit. –Katy Tomasulo

New Glass Introductions Boost Efficiency

Thursday, April 29th, 2010

Sage Electrochromics' electronically tintable glass.

Two glass manufacturers recently introduced or expanded their energy-efficient glazing options.

Sage Electrochromics now offers its electronically tintable glass in combination with triple-pane construction for R-values greater than 8. Combining the company’s electrochromic capability, which uses nanotechnology to allow occupants to control daylight and solar heat transmittance, with higher-efficiency glazing provides advanced thermal performance along with solar heat gain and glare control, according to the firm.

Depending on the time of day, the tintable glass, which the company has offered for some time, can go from completely clear, with an SHGC of 0.48, to heavily tinted (during times of direct sunlight) for a 2% visible light transmittance and an SHGC of 0.09.

The glass also can be “zoned” into different tints, thereby allowing for direct sun to be blocked by a darker tint on the upper part of the window while maintaining a clear lower zone to transmit ambient light.

In addition to manual control, the tinting can be fully automated to change throughout the day via home automation controllers.

Owens Corning's Innovision windows

Glass manufacturer Southwall recently announced that its Heat Mirror insulating glass is available on Owens Corning’s new Innovision line of fiberglass windows. Heat Mirror glass consists of one or more low-emissivity and solar-reflective Heat Mirror films suspended within insulating glass to create two to four insulating cavities for an insulation performance from R-6 to R-20. Innovision windows feature a slim-line frame for a lighter weight and larger glass area. –Katy Tomasulo

Online Calculator Estimates Cool Roof Savings

Thursday, April 22nd, 2010

During a Webinar April 22, representatives from the DOE, Oak Ridge National Laboratory, and Lawrence Berkley National Laboratory, among others, launched a Roofing Savings Calculator designed to make it simple for consumers, contractors, and other entities to determine the potential energy savings of installing a cool roof.

The calculator is based on DOE-2, a well-established software program that analyses a building’s energy use. Because that FORTRAN-based system is geared toward engineers, the collaborators’ goal for the Roof Savings Calculator was to provide a user-friendly, Web-based interface that any layman could use.

To calculate the energy savings of replacing an existing roof with a cool roof, users simply answer a series of questions about the home, including location, square footage, heating system efficiency, and attic insulation, as well as information regarding the proposed replacement roof; “simple” and “advanced” modes are offered depending on the knowledge level of the user and some questions provide links to additional explanation and information.

Upon completing the questions, the user receives a calculation of potential yearly and monthly savings. Results also can be emailed.

The Roof Savings Calculator can be found at www.roofcalc.com. –Katy Tomasulo
