Homebuyers today are increasingly concerned about the indoor air quality of their homes.

Issues like mold, radon, carbon monoxide, and toxic chemicals have received greater attention than ever as poor indoor air quality has been linked to a host of health problems.

To address these concerns, builders can employ a variety of construction practices and technologies to decrease the risk of poor indoor air quality in their new homes.

EPA created the Indoor Air Package to help builders meet the growing consumer preference for homes with improved indoor air quality and energy efficiency. By constructing homes that meet EPA's stringent specifications, forward-thinking builders can distinguish themselves by offering homes that have earned this designation.

EPA's Indoor Air Package specifications were developed based on best available science and information about risks associated with indoor air quality problems, and balanced with practical issues of cost, builder production process compatibility, and enforceability. The initial specifications were piloted in several cities and revised based on input from the field.

Energy Star Builders Offer the Indoor Air Package

The Indoor Air Package is now available for all interested ENERGY STAR Partners. The current Indoor Air Package specifications (330K), dated April 19, 2007, supersede all previous versions of the specification. ENERGY STAR qualified homes that comply with these specifications and are verified with a completed Indoor Air Package Verification Checklist can earn the Indoor Air Package label.

Recycling markets for post-consumer asphalt roofing shingles (tear-offs) are starting to gain ground. The blossoming green building movement, emphasis on environmental stewardship, increasing oil prices, aggregate shortages, efforts to decrease greenhouse gas emissions, state recycling programs and regulations, local recycling ordinances, increasing tipping (disposal) fees and difficulty choosing sites for new landfills are some drivers pushing recycling of construction and demolition materials into the limelight.

In addition, the U.S. Environmental Protection Agency's (EPA's) Resource Conservation Challenge is drawing attention to reuse and recycling of construction and demolition materials.

According to the Construction Materials Recycling Association (CMRA), an estimated 11 million tons of asphalt roofing shingles are generated annually in the U.S., and some estimates are higher. Compared with other construction and demolition materials such as metal, concrete and asphalt pavement, only a small percentage of asphalt shingle tear-offs are currently recovered, leaving significant opportunity to use recycled asphalt shingles.

The primary use for recycled asphalt shingles in the U.S. is as a road building material, particularly for use in hot-mix asphalt. Other uses of recycled asphalt shingles include cold-mix asphalt, cold patch, road base, dust control, mulch, temporary roads and fuel.

The benefits derived from using recycled asphalt shingles stem from the recovery of asphalt cement and mineral aggregate components of shingles, each of which represent about 20 to 40 percent of a shingle's weight. With the price of oil at an all-time high and aggregate shortages being experienced in some areas of the U.S., there are obvious reasons to investigate opportunities to recycle shingles.

Resources

Check out www.shinglerecycling.org, a comprehensive clearinghouse of information about the subject.

The Web site includes overviews of shingle recycling in each state (including state regulations, environmental agency contacts and all known recyclers), economics of recycling, markets for recycled shingles, pertinent environmental regulations, worker health and safety issues, a library of literature on shingle recycling and current research.

Environmental issues

Environmental Issues Associated with Asphalt Shingle Recycling discusses two main environmental concerns: asbestos, which occasionally is found in the fiberglass or felt mat of shingles, and polycyclic aromatic hydrocarbons (PAHs), which occur naturally in asphalt products.

Best practices

Recycling Tear-Off Asphalt Shingles: Best Practices Guide provides a starting point for shingle recyclers to plan a new operation or improve an existing one. It focuses on business planning, recycling operations, marketing strategies and compliance recommendations and identifies three major best practices, each with a number of supporting points:

1. Recyclers should implement quality-assurance and -control systems to carefully control the quality of their incoming supplies of shingle tear-off materials.
2. Recyclers' end product, recycled asphalt shingles, should meet or exceed material specifications of their end markets.
3. A recycler's business plan should include a marketing plan based on multiple outlets for recycled asphalt shingles.

Economic Issues

Shingles are heavy, making transportation a limiting factor in any recycling project. The recycling tipping fee must be cost-competitive for a roofing contractor to choose recycling instead of disposal. Likewise, a recycled asphalt shingle product must be priced competitively because end-users are more likely to choose a nontraditional or recycled product if it will save them money. And finally, preference for using recycled asphalt shingles varies among hot-mix asphalt plant operators.

Materials specifications also are critical for market development. State department of transportation (DOT) specifications often are relied on by county and local public works engineers and used on private jobs and DOT projects. However, only a handful of state DOTs (Georgia, Missouri and South Carolina) currently have specifications for using recycled asphalt shingles in hot-mix asphalt.

Other states (Indiana, Massachusetts, Minnesota, North Carolina, New Jersey, Pennsylvania, Texas and Virginia) have specifications for the use of manufacturers' shingle scrap in hot-mix asphalt though the volume of available manufacturers' scrap is insignificant compared with the volume of shingle tear-offs generated annually.

How to Recycle Shingles in YOUR State

Recycling presents great environmental stewardship opportunities for the roofing industry. If you are interested in recycling asphalt shingles, research the resources currently available in your state, including state specifications.

You can find this information and key contacts for your state agencies at www.shinglerecycling.org under the State Experience section. Your state regulator will help you learn what can be recycled in your state and how to do it. If you want to start a recycling operation, don't learn by trial and error—you can refer to the best practices guide to glean the cumulative wisdom of the pioneers of asphalt shingle recycling.

Remember, you may be able to reduce your disposal costs by keeping asphalt shingles and other construction and demolition materials out of landfills. And substituting reused or recycled materials in place of virgin materials can result in substantial energy savings and greenhouse gas emissions reductions—and you can make that happen.

Shingle Recycling Business Opportunity

So where's the business opportunity in shingle recycling? On the front end, you obviously can save money by recycling if a recycling tipping fee compares favorably with costs of local landfill tipping fees.

But what about recyclers and end-users, particularly hot-mix asphalt producers? In general, most private companies don't want to discuss their operations, and because local conditions such as tipping fees vary widely, no single example can be representative of all operations.

But a hypothetical, conservative scenario can help reveal some information.

Assuming the asphalt shingles torn off a roof system are 20 percent asphalt, the price of liquid asphalt cement is $300 per ton and about 75 percent of the asphalt in the shingles is "available" to replace virgin asphalt cement in hot-mix asphalt, then the value of the asphalt in the recycled asphalt shingles is about $45 per ton.

If we assume a recycler and hot-mix asphalt producer split the value of the recycled asphalt shingles, $22.50 per ton is paid to the recycler less about $15 per ton for processing and transportation costs, leaving the recycler with about a $7.50 per ton profit on the processing side of the operation alone.

Profitable recycling ventures need revenue from their tipping fees as well as from the sale of recycled materials. If a recycler sets his tipping fee for asphalt shingle tear-offs at 50 to 75 percent of the landfill tipping fee, there is a financial incentive for people to recycle.

Presorting Shingles

Recycling Tear-Off Asphalt Shingles: Best Practices Guide (which is available for FREE at www.shinglerecycling.org) explains that presorting can be done quite reasonably by roofing contractors—the goal isn't to remove every last nail from the shingles but to keep wood, plastic and other debris in separate piles.

With the price of petroleum-based products at an all-time high, this conservative, back-of-the-envelope estimate shows that shingle recycling can be quite profitable.

ROI for Roofing, Recycling and Paving

And the economic and environmental benefits are shared across the roofing, recycling and paving industries.

Dual flush toilets have become standards in Europe and other countries concerned about their water supply.  Unfortunately, water conservation is undervalued in the US.  But that is changing, especially where drought is forcing water outages and increasing rates.  Gerber provides high efficiency toilets, sinks and certified water efficient solutions. 

Gerber offers vitreous china pedestal and drop-in lavatories designed to complement their toilets, bringing together classic looks and powerful technology. The advanced HP2 and XP3 high-performance flushing systems will virtually eliminate the aggravation and cost of warranty callbacks from second-class toilets that clog or require a “double flush.”

Abigail™ faucets, and Viper™ toilets with Gerber's HP2 flushing system, which delivers performance that’s more than double the industry standard! Gerber provides you with the style and quality you need to give homebuyers who are stepping up from their first home the sense that they’ve truly arrived.

Gerber offers water-saving, sensor-operated electronic faucets designed to prevent waste by automatically shutting off water flow. Deckmount choices include gooseneck or crescent spouts, as well as, models
equipped with an in-deck mixer, which permits user control of water temperature.

Ultra Flush® 1.1 gpf toilet models are available to deliver the ultimate in high-efficiency water conservation.
They can flush 1,000 grams of bulk waste while using 30% less water than standard 1.6 gpf toilets. In addition to Ultra Flush 1.1 gpf units, Ultra Dual- Flush™ models are also available, with a dual-action lever that permits 1.6 gpf or high-efficiency 1.1 gpf operation.

Ultra Dual-Flush™ provides professional performance while conserving natural resources. It flushes up to 1,250 grams of bulk waste per 1.6 gallon flush or 1,000 grams per 1.1 gallon flush.  1.1 gallon flush uses 30% les water over conventional 1.6 gallon toilets.  The Pressure-Assist system uses pressure from the incoming supply line to foce 1.6 gallons of work out of 1.1 gallons of water. It installs like standard gravity toilest -- no special connections are required.

The old fashioned bathroom stool can use up to 3 gallons of water per flush. New toilets use considerably less and the new "dual flush toilet" lets you save the most. The flush button for "light flush" uses lss than a gallon of water, and the heavier flush (for solids) uses about 1.5 gallons. These amounts vary by product and by certification by trusted programs such as EPA's Watersense standard.

Designed in Australia, where water conservation is extremely important, the HET dual flush water-saving toilet uses, at most, 1.6 gallons per flush. “Dual flush” means that this toilet has two different types of flushing. One for liquids (or #1), which is only .8 gallon of water, and one for solids ( like #2, c’mon let’s be grownups about this!), which is only 1.6 gallons of water. At its biggest flush, this water still uses less than the standard new toilets, which use 1.8 gallons of water per flush. That’s up to 50-75% savings!

Remodeling doesn't always mean ripping out walls -- if you think green, you can rip out utility costs!

Forest Conservation Program

SCS developed its Forest Conservation Program in 1991 and has since emerged as a leading certifier of forest management operations and wood product manufacturers. In 1996, the Forest Stewardship Council (FSC) accredited SCS as a certification body, enabling it to evaluate forests according to the FSC Principles and Criteria for Forest Stewardship. Through a well-developed network of regional representatives and contractors, SCS offers timely and cost-effective certification services around the world.

Over the past 12 years, SCS has certified more than 23.8 million acres of natural forests and plantations in North, Central, and South America, Europe, Asia, and New Zealand through its Forest Management Certification division. Certified operations have ranged from small 100-hectare parcels to 2.5-million hectare forests. SCS also offers a group certification format, such as certified resource managers, to lower certification costs for small landowners. For each certification audit, an interdisciplinary evaluation team of experts in forest science and management is assembled.

Since the mid-1990s, SCS has also offered FSC certification to wood product manufacturers. Our Chain-of-Custody Certification division has audited and certified over 500 manufacturers, distributors, and retailers who make or carry certified wood products. SCS has issued chain-of-custody certificates in over 29 countries spanning 5 continents.

In addition to FSC certification, SCS offers an independent, non-aligned certification program for clients seeking an alternative to existing, potentially polarizing certification schemes. SCS also offers wood product manufacturers the option of pursuing single attribute claims (e.g., recycled, recovered, salvaged wood, etc.) certification.

As of February 4, 2008, SCS is a CCX-approved verifier for >forestry offset projects.

Chain-of-Custody Certification

Before a product may carry an FSC or SCS label, all stages of the production, distribution, and sale of the product must be independently evaluated. Wood must be tracked from the certified forest to the finished product.

Through our Chain-of-Custody Certification Division, SCS certifies wholesalers, manufacturers, distributors, and retailers, who handle wood coming from forests certified according to FSC standards. For FSC Chain-of-Custody certification SCS also provides group and multi-site certification. To become certified, these entities must meet six principles of chain-of-custody, such as maintaining adequate inventory control systems that allow for separation and identification of certified product.

SCS requires the tracking of certified products throughout the production process to ensure the validity of the certified claim. If a wood product carries the FSC or SCS logo, a customer can have confidence that it was made from wood harvested from an FSC-certified forest.

Green building and green workspace strategies include conscious design principles that reduce the load on the environment -- and people's health.  The use of non-polluting materials and manufacturing processes of basic building and manufacturing processes is the foundation of a green building.  How the building itself is constructed is the second step toward lowered lifetime impact through lower energy costs, better ventilation, lower offgassing, etc.  And the furnishings that make the building functional add the final step in the green building process by selecting furnishings that reduce virgin materials use, are high performance and long lasting, and provide ergonomic service to the people using them.

Whether you are building a new facility or retrofitting a building, finding good quality, green building materials is part of the upgrading process...and part of certification programs such as Energy Star, California standards, Federal Environmentally Preferable Purchasing or USGBC's LEED program.
