Erosion control is an important issue both on job sites and with ecological restoration
projects. North American Green has long been a leader in erosion-control products. Though their 100%
biodegradable BioNet® series of erosion-control mats have been around a long time (since 1993), this
product was new to the GreenSpec Directory in 2005. BioNet mats have a core of straw or straw and
coir (coconut fiber) held by a woven jute netting and stitched with cotton thread. The mats are
secured to the ground with biodegradable stakes made of either corn-derived polylactic acid (PLA) or
wood. The company also makes erosion-control mats held together with photodegradable polypropylene,
but these products are far less biodegradable than the natural fibers used in BioNet.

Columbia Forest Products, the largest North American manufacturer of hardwood plywood, announced
this year a transition to soy-based binders for all of its veneer-core and veneered agrifiber-core
panel products. The company's recently branded PureBond™ panels use the soy-based binder in place of
the industry-standard urea-formaldehyde, which results in significant emissions of formaldehyde.
(Formaldehyde was reclassified in 2004 by the International Agency for Research on Cancer from a
"probable human carcinogen" to a "known human carcinogen.") The new binder, developed by scientists
at Oregon State University, is 87% soy protein, with the remainder a proprietary petrochemical-based
polyamide resin. The new binder is water-based, non-flammable, and nontoxic; water vapor is the only
emission during curing, according to Steve Pung of Columbia Forest Products. The switch to this
binder has had no effect on product pricing, and all Columbia Forest Products manufacturing
facilities are expected to complete this conversion during 2006. The company's agrifiber-core panels
are made from straw, a waste agricultural product, and among the wood veneers offered are those that
are certified according to Forest Stewardship Council (FSC) standards.

Discarded carpet is a huge solid waste problem in North America, with more than 2 million tons
of carpet entering the waste stream each year. NYCORE, Inc., based in Atlanta, Georgia, produces
several products that are made of recycled carpet (both post-consumer and post-industrial recycled
material). Nybacker™, is a strong, flexible, tile backer available in 3' x 5', 4' x 4' and 4' x 8'
sheets in 1/4" and 1/2" thicknesses. The product is typically laid over CDX plywood. One side of the
backerboard has a rough surface with indentations to aid in tile adhesion. The company also
manufacturers the roofing product Ny-Slate, and is working on new product introductions in late 2005
and 2006, including a storm board product. Unlike cement-based backer-board, Nybacker does not
release silicon dust, which is implicated in the health problem silicosis, when it is cut. Nybacker
is comparable in price to cement backerboard.

Stonescape™, from American Biltrite Canada, is a brand-new, PVC-free alternative to vinyl
composition tile (VCT). This resilient flooring tile is made from limestone and ethylene acrylic
polymers. Along with being free of polyvinyl chloride (PVC), the tile is free of other halogens and
plasticizers, and it emits no volatile organic compounds (VOCs). It is also a much harder material
than VCT (2,000 psi vs. less that 300 psi for most VCT) that will require far less regular surface
treatment (stripping and waxing) than VCT, according to the manufacturer; this will result in lower
VOC emissions. As a new product, Stonescape has little track record to date, though an initial
year-long test installation has apparently been very successful.

Terratex® is a family of fabrics designed to minimize environmental impacts and push the
envelope with recycled and bio-based material use. The Terratex brand was launched in 1996 with
polyester fabrics made from post-consumer and post-industrial recycled PET plastic and from
reclaimed wool. In late 2004 the company introduced fabrics made from the bio-based polymer
polylactic acid (PLA), which is produced from corn and other agricultural feedstocks by NatureWorks,
LLC (previously Cargill-Dow) under the name Ingeo™. Designed primarily as panel fabrics for
commercial workstations, Terratex PLA fabrics are now available on workstation panels from Herman
Miller, AllSteel, and Teknion, and in September 2005 Carnegie began offering Terratex PLA fabrics
under the name INSIGHT™.

While dual-flush technology has been increasingly migrating to gravity-flush toilets, Sloan
Valve Company is the first company to introduce this flush option to commercial toilets that rely on
water-line pressure. The dual-flush option allows a toilet to operate with a standard flush for
solid wastes and a lower-volume flush for liquid wastes and paper. The Sloan Uppercut™ flushometer
uses 1.6 gallons when the valve handle is pushed down, or 1.1 gallons when the handle is pulled up.
The unit is sold as a complete flushometer or as a retrofit kit for Sloan Royal®, Regal®, and Crown®
II and other similar-style manual flushometers. If retrofitted onto older flushvalves that use more
water, the savings with the light-flush is about 30%--savings of about 1 gallon for a 3.5-gallon
flushometer. The Uppercut handle's metallic silver-ion antimicrobial coating protects against germs,
and its green color distinguishes it from standard flush-valve handles.

TOTO has long been a leader in high-performance, low-flush toilets. In 2005, the company
introduced its Aquia™ dual-flush toilet to the North American market. Dual-flush toilets, long
popular in Australia, Western Europe, and East Asia, offer two flush options: a standard flush for
solid wastes and a lower-volume flush for liquid wastes and paper. The Aquia toilet, a top-selling
product in Thailand where it is manufactured, uses 1.6 gallons at the full flush and 0.9 gallons at
the low flush. The company estimates that a typical family of four will save approximately 7,000
gallons of water per year with this toilet, compared with a standard 1.6 gallon-per-flush toilet. In
terms of flush performance, the toilet successfully removes 800 grams of test media at full flush,
based on standardized MaP tests (see Environmental Building News, January 2004). The toilet is
offered in six colors.

Thermal energy storage using ice or chilled water has long been an option for shifting cooling
loads to off-peak periods in commercial buildings with chillers. This benefits the utility company
by leveling peaks in electricity demand while reducing costs to building owners who pay demand
charges or have time-of-day billing rates. In January 2005, Ice Energy, Inc., introduced the Ice
Bear™ thermal energy storage system for small commercial buildings and large homes. The Ice Bear 50
uses a standard 5-ton condensing unit at night to freeze about 500 gallons of water in a 6' x 5' x
6', insulated energy storage module. During the daytime, a small electric pump circulates
refrigerant through the ice and delivers cold refrigerant to a standard evaporator coil (up to 7.5
tons) and blower in the building to provide cooling. Peak daytime electricity demand and consumption
for cooling are reduced by 95%. The Ice Bear 50 is designed for commercial buildings from 2,000 to
150,000 square feet in size that rely on split or packaged refrigerant-based air-conditioning
units--especially government and office buildings and retail stores in the "Starbucks to Wal-Mart"
size. A smaller Ice Bear 30, specifically designed for mainstream homes, is currently being tested.

Energy recovery ventilators (ERVs) replace stale indoor air with fresh outdoor air, transferring
heat and humidity from the exhaust air to the incoming fresh air. Stirling Technology, Inc., brought
ERV design to a new level of controllability and efficiency with the introduction of its
UltimateAir™ RecoupAerator® 200DX system. The brushless DC, variable-speed, electronically
commutated permanent-magnet (ECPM) motor allows the 200DX to deliver 50 to 200 cfm of airflow very
efficiently, even at low flow rates. It also achieves very high (up to 96%) heat-recovery
efficiency. Optional features include an economizer module that provides free cooling when outdoor
conditions permit, a CO2 sensor for boosting airflow during periods of high occupancy, an automatic
pressure sensor that adjusts airflow to maintain a user-set differential pressure, and an integrated
HEPA air filtration module. Stirling ERVs are manufactured in Athens, Ohio.

With the introduction of its Enbryten™ luminares using high-efficacy, white LEDs (light-emitting
diodes), Permlight Products is helping to usher in the age of LED lighting. LEDs are the only
non-incandescent light source that does not rely on mercury vapor; efficacy has increased
dramatically in recent years--to over 50 lumens per watt for today's best white LEDs. LEDs also have
a very long life: from 30,000 to 50,000 hours. Permlight is using these high-efficacy LEDs in a
range of pendant, downlight, and sconce LED luminaires that are being installed in homes and
commercial buildings. The Enbryten ENBC series downlight luminaire, for example, can effectively
replace a 60-75 watt incandescent luminaire, yet consumes just 15-18 watts. The ability to focus
light from LED luminaires can allow such a luminaire to replace an incandescent luminaire that has
higher total light output. Enbryten luminaries have replaceable LED modules, allowing easy
replacement as needs change or LEDs improve.
