A sneak peak at the Top 10 Green Products

November 01, 2005 |

Adual-flush toilet designed for the commercial market and a "pint-sized" thermal energy storage system for small commercial and residential buildings are among the winners of BuildingGreen's 2005 Top 10 Green Products awards. The Brattleboro, Vt.-based publisher of the GreenSpec product directory and Environmental Building News evaluated hundreds of new products to compile its fourth annual list, which will be announced this month at the U.S. Green Building Council's Greenbuild Conference in Atlanta. Here's a sneak peak at two products that made the list:

Sloan's Uppercut dual-flush flushometer valve is the first dual-flush toilet designed specifically for the commercial market. The dual-flush option allows the toilet to function with two different flush volumes: a standard 1.6-gallon flush for solid wastes and a 1.1-gallon discharge for liquid wastes and paper. Users simply pushed down or pulled up on the valve handle to activate the desired flush.

The unit is sold as a complete flushometer, or as a retrofit kit for Sloan Royal, Regal, Crown II, and other similar-style manual flushometers. If retrofitted onto flushvalves that use more water, the savings at the light-flush is about 30%—savings of about one gallon for a 3.5-gallon flushometer.

Sloan recommends that the flush performance will be best when used with a late-generation toilet bowl designed to flush with 1.6 gallons.

The Uppercut handle has a metallic silver-ion antimicrobial coating for protection against germs and is green in color to distinguish it from standard flush-valve handles. www.sloanvalve.com

The Ice Bear 50 from Ice Energy is an ice-based thermal energy storage system designed for smaller commercial and even residential buildings. The system is composed of a standard five-ton air-conditioning condensing unit that operates at night to freeze about 500 gallons of water in a 5×5×5-foot insulated energy storage module. During the daytime, a small 100-watt electric pump circulates refrigerant through the ice and a standard 7.5-ton evaporator coil and blower in the building to provide the cooling. Daytime electricity use for cooling is reduced by 95%. Along with the benefits of reducing peak electricity use, the compressor can actually operate more efficiently in some situations, because 1) the outside air is cooler at night, 2) a smaller compressor can be used, and 3) the compressor does not cycle on and off during the ice-making.

The Ice Bear 50 is designed for commercial buildings of 2,000–50,000 sf that rely on packaged air-conditioning units. The primary market is retail stores in the "Starbucks to Wal-Mart" size, according to Ice Energy. www.ice-energy.com

LED Lamps Enlighten and Save Energy

Westhinghouse's Nanolux LED lamps provide uniform light distribution through their patented polymer magnification and dispersion system. Lasting up to 100,000 hours, the energy-efficient LED lamps can be used in indoor and outdoor applications including signs and lighting fixtures. LED lights use up to 88% less energy (based on 24 hours per day usage and the national average cost of energy at ten cents per kw/h. Available in a variety of colors, Nanolux is the only LED lamp UL listed for use in wet environments.

Ventilated, Insulated Roof Panels

Hunter Panels' Cool-Vent rigid roof insulation panels are manufactured as ventilated nailbase panels that promote air circulation within the roof assembly. The steep-slope boards have sustainable thermal insulating characteristics, including an APA-rated OSB or plywood top layer, a middle layer of wood spacers, and a bottom layer of polyisocyanurate foam that help eliminate moisture vapor and heat build-up. The panels are recommended for use on roof slopes greater than 1:4.

Self-Adhering Wall Coverings

Milliken & Company's new wall covering, called 180 Walls, hangs with pressure-sensitive adhesive, not paste. The company says the "dry" installation prevents shrinking and peeling, and enables the covering to be removed years later without damage to wall surfaces. The polyester covering comes in four textured, permeable patterns that allow air and moisture penetration so walls can breathe. An antimicrobial agent is incorporated into the material to prevent mold and mildew growth. Additionally, the covering incorporates the company's StainSmart technology that repels fluids to prevent liquid -based stains, according to the manufacturer.

Easy-to-use, Compact Fluorescent Lighting

Lithonia Lighting's CKP residential compact fluorescent downlights have a plug-and-play feature that reduces installation time by 35%, the company says. The fixture is shipped with two housings: a remote unit factory-installed with a pre-wired 11-foot flex cable, and a master unit with an electronic ballast and a junction box. A plug-in connection in the field links the two units. CKP holds two 26-watt, 4-pin triple-tube fluorescent lamps that use one-third the wattage of common incandescent lamps, according to the company.

A Blue Look for Architectural Glass

PPG has introduced Vistacool Azuria glass, a reflective, color-enriched architectural glass that has an aqua-blue appearance and transmits high levels of daylight. The new glass was created to fill the needs of customers who wanted tinted high performance architectural glass with high visible light transmittance and reflectivity that is more muted than the mirror-like finish of traditional reflective glass. Vistacool Azuria provides Visible Light Transmittance (VLT) of 47%, and a Solar Heat Gain Coefficient (SHGC) of 0.34. These combinations produce light to solar gain (LSG) ratios of 1.39 to 1.62, exceeding the U.S. Department of Energy's standard for spectrally selective glasses, 1.25 or better.
