Green is in high demand. Today’s homeowner faces skyrocketing energy prices and indoor health hazards and lives with the pressing fear of global warming.
The Environmental Protection Agency (EPA) warns about the health effects of poor Indoor Air Quality from the off-gassing of Volatile Organic Compounds (VOCs).
Materials such as insulation, paints, stains, carpeting, flooring and countertops can produce significant off-gassing in the home so manufacturers have responded with some environmentally friendly innovations.
The idea behind green building is to increase the efficiency of buildings and their use of resources like energy, water and building materials to protect human health and the environment. The U.S. Green Building Council is leading the movement with its LEED program — Leadership in Energy and Environmental Design. The LEED Green Building Rating System is the nationally accepted benchmark for the design, construction and operation of green buildings.
LEED promotes sustainability through five key areas of human and environmental health: sustainable site development, water savings, energy efficiency, materials selection and indoor environmental quality. Fortunately, the list of product offerings that address these topics is constantly growing.
A carbon footprint is a measure of the impact human activities have on the environment in terms of the amount of greenhouse gases produced, measured in units of carbon dioxide. Fiberglass insulation tends to have a high carbon footprint from energy intensive production, and some have associated health concerns in terms of off-gassing. Now there are some interesting insulation alternatives to pick from.
Dryvit Exterior Insulation and Finish Systems (EIFS) is a cladding system for commercial and residential construction, offering a highly energy-efficient, lightweight engineered cladding system in a vast array of finish options. Dryvit is available in a number of system configurations to match any climate or building condition. In testing by the Oak Ridge National Laboratory, Dryvit proved to be 84 percent more energy efficient than the next best performing cladding material. When a building uses Dryvit’s systems, energy consumption for heating and cooling the building is reduced on average by 20 to 40 percent.
Tex-Cote Super-Cote Cool Wall coatings from Textured Coatings of America Inc. have been shown to reduce air-conditioning demand by nearly 22 percent. The exterior coating’s heat reflective finish reduces exterior wall temperatures by as much as 40 degrees F when compared to traditional paints and coatings, and they lower interior temperatures in both concrete block and stucco and wood-frame homes. The coatings utilize the same heat reflective technology used by the military to reduce the heat signature of planes and other vehicles. Since the increase in reflectivity occurs in the infrared spectrum, it is invisible to the naked eye. These thick coatings are available in more than 500 heat reflective colors and can be applied to virtually any type of surface including stucco, wood, masonry and fiber cement.
“A dark-colored home absorbs as much as 90 percent of the solar radiation that strikes it, and even white walls can absorb 70 percent of the solar radiation that strikes them,” explains Jay Haines, president and chief executive officer of Textured Coatings of America Inc. “By reflecting this infrared radiation rather than absorbing it, the Cool Wall exterior coatings dramatically reduce the load on a home’s air-conditioning system.”
InsultCot offers insulation made from 80 percent cotton fibers and 20 percent polyester. The product is safe, efficient and environmentally friendly. InsulCot insulation contains no hazardous materials and requires no respiratory or safety equipment for installation. And installing InsulCot allows homeowners to claim a tax credit of 10 percent of the cost of energy saving home improvements.
Using GreenFiber’s Cocoon cellulose insulation contributes to LEED certification. Made with reclaimed newsprint, GreenFiber’s natural fiber insulation products consist of 85 percent recycled content with the remaining content consisting of fire-retardant and stabilizing additives. Based on data from the National Solid Wastes Management Association, recovered newsprint is one of the largest components of the residential waste stream. Insulating a typical 1,500-sq.-ft. home with cellulose insulation recovers as much newsprint as an individual will consume in 40 years. The products contain no asbestos, formaldehyde, mineral wool or fiberglass. Cocoon is treated with permanent fire-retardants to meet and exceed the ICC standards for a Class 1/A fire rated building materials.
To help customers select paint based on green coating standards, Sherwin Williams created their “GreenSure” designation. The company’s Duration Home Interior line features the GreenSure designation for environmentally preferred products with maximum performance. This interior finish promises superior washability and burnish resistance, and is available in matte, satin and semigloss finishes along with deep, vivid accent colors. A patented cross-linking formula prevents stains from penetrating, and this finish is antimicrobial so it inhibits growth of mildew.
MechoShade’s Mecho/5 with EcoVeil shade cloth is a complete solar shading system that is an environmentally friendly system. Mecho/5 is a manual solar shading system that installs easily and operates smoothly with accessories including fascia, pockets, closures and side channels. The EcoVeil shade cloth is made from a new material — a thermoplastic olefin (TPO) based yarn — and is washable, UV-resistant and flame-retardant. Mecho/5 is also antimicrobial, does not support staph and mildew and contains no VOCs, so it does not contribute to sick building syndrome.
Reclaiming the Floor
According to Frank Endrenyi, vice president of sustainable development for Mohawk, “our studies show that half of U.S. consumers now recycle either bottles or newspapers. In 2004, 21 percent said they voted for candidates in part based on their environmental records. Ninety-nine percent of school children now have access to environmental classes.”
For Mohawk SmartStrand, petroleum is substituted with corn sugar to create Bio-PDO — a key ingredient in the carpeting made with DuPont Sorona polymer. SmartStrand promises superior stain resistance for substances including mustard, red wine, bleach, acne medication, and others. Mohawk recently launched a new umbrella program called “Greenworks” that places all green projects under a single platform for their customers and shareholders.
EcoTimber is the first flooring company in North America to offer bamboo flooring made with formaldehyde-free adhesives as a standard product. EcoTimber uses top-quality mature bamboo stalks and a low-VOC European adhesive that falls far below the European E1 standard for indoor air quality. The flooring is prefinished with an aluminum oxide enhanced acrylated urethane system with a hardened acrylic anti-scratch topcoat to protect against abrasion and scratching.
WaterSense is a partnership program sponsored by the EPA. Its mission is to protect the future of our nation’s water supply by promoting and enhancing the market for water-efficient products and services. Many manufacturers offer products that meet WaterSense standards, but some go above and beyond the standards for water conservation with maximum efficiency.
Toto’s Aquia Dual Flush Toilet allows the user to select the amount of water the toilet flushes: 0.9 gal. per flush (gpf) or 1.6 gpf.
