Cradle to Cradle Partners with Healthy Building Network to Add Hazard Screening Profiles to Chemicals and Materials Library

The Cradle to Cradle Products Innovation Institute has recently completed a project with the Healthy Building Network (HBN) to include a Cradle to Cradle view in the Pharos Chemicals and Materials Library (CML). This view will allow anyone with access to Pharos to screen any of the more than 30,000 substances currently catalogued in HBN’s CML using the Cradle to Cradle Certified protocol.

The Cradle to Cradle Material Health Assessment Methodology helps manufacturers on the path to product optimization through a four-stage evaluation: Inventory-knowing what’s in it; Screening-identifying known hazards; Assessment-a full toxicological assessment against 24 human and environmental endpoints; and Optimization-using materials that are safe for humans and the environment. HBN’s CML is an independent, comprehensive database for identifying health hazards associated with building products based on authoritative hazard lists. The addition of the Cradle to Cradle view to the CML provides access to screening Cradle to Cradle hazard profiles, which include Cradle to Cradle red/yellow/green hazard ratings for each endpoint where a chemical has been listed on any one of 37 applicable authoritative hazard lists. Chemicals are easily searchable by chemical name or CAS Registry Number.

This allows manufacturers and product designers to quickly and easily identify toxic chemicals that could lead to “X assessments,” a designation within Cradle to Cradle’s Material Health Methodology identifying highly problematic substances that are targeted for phase-out, including known carcinogens, mutagens and reproductive toxicants. The tool also readily identifies substances on Cradle to Cradle’s Banned Chemicals Lists. Manufacturers can prescreen materials and products to identify potentially problematic substances before beginning more in-depth work with an assessor for Cradle to Cradle certification. Meanwhile, product assessors can use the tool to streamline the list-screening step of the Material Health Assessment process.

“This partnership and tool will empower manufacturers and product designers to make early and informed decisions, and will help to motivate them to start on the path toward Cradle to Cradle certification and pursue continuous improvement in our program,” says Susan Klosterhaus, Ph.D., vice president of Science and Certification for the Cradle to Cradle Products Innovation Institute, which administers the Cradle to Cradle Certified Products Program. “This is one of many steps that we are taking to make Cradle to Cradle certification more approachable and provide tools and resources for manufacturers who want to pursue regenerative design.”

“We are excited to collaborate with the institute to help manufacturers quickly access critical information to inform the selection of inherently safer substances for use within their products,” says Tom Lent, policy director of the Healthy Building Network, which built the screening tool. “Bringing together the power and scope of the Pharos database with the assessment insights of the Cradle to Cradle certification process advances our mission by empowering manufacturers and will not only aid in the optimization process, but will ultimately result in better products for architects and designers. By providing the Cradle to Cradle screening level profile along with indicators from GreenScreen, U.S. EPA Design for the Environment, Living Building Challenge, and other programs, this tool provides manufacturers a useful one-stop shop for the initial scoping on their path to full optimization.”

Clay Tile Roofing Protects a Subdivision’s Clubhouse from the Hot Phoenix Sun while Providing an Old World Look

Located in the Sonoran Desert southeast of Phoenix, the Encanterra Country Club subdivision offers upscale living in houses built by Walnut, Calif.-based Shea Homes and surrounding an 18-hole golf course designed by Tom Lehman. The centerpiece of this vibrant community, however, is the 60,000-square-foot country club known as La Casa, The Club at Encanterra.

The centerpiece of the Encanterra subdivision in Phoenix is the 60,000-square-foot country club known as La Casa, The Club at Encanterra.

Designed to keep the community’s members active and entertained, La Casa, The Club at Encanterra contains four restaurants, a full-service spa, fitness center and three swimming pools. The club features Mediterranean-style architecture to essentially be an extension of the attractive homes in the subdivision.

To achieve a rustic, Old World appearance, Shea Homes specified a two-piece clay tile roof installed in mud set, accented with copper flashings; custom-fabricated ornamental details; and a spray-foam system on the low-slope roof areas. Only a roofing contractor with the experience and capabilities to do all facets would suffice.

Phoenix-based Century Roofing Inc., which has been in business since 1991, has a long history of commercial and custom residential projects. With crews experienced in installing all types of tile, as well as its own metal fabrication shop, the contracting company was chosen to roof the club as it was being built.

Hustling for the Job

Steve Schwoerer, president of Century Roofing, knows what it takes to hustle and land large jobs, like La Casa, the Club at Encanterra. Knowing the project was going to be a landmark building in the valley attracted him to it. “We got it off the permit list, pursued it, bid on it and landed it, although not quite so cut and dry,” he says. “We have a lot of custom-home
experience and in Phoenix that means clay tile roof experience, so it fit in perfectly with our abilities.”

Originally, the club’s designer specified a different type of clay tile than what was actually installed on the roof. However, Schwoerer invited Irvine, Calif.-based Boral Roofing to come up with a color match and submit a quote for its tile to be installed on the project. “Boral had their plant manager fly into Phoenix to look at the roofing on the existing guard house that Shea Homes was trying to match,” Schwoerer recalls. “Boral then formulated a custom-blended tile and shipped the tile to Phoenix so a mock-up could be done for the architect’s approval, which they received.”

In addition to its curb appeal, the tile offered other benefits. Manufactured from naturally occurring geologic material (59 percent of which is recycled content), Boral clay tiles have received Cradle to Cradle Gold certification from the Cradle to Cradle Products Innovation Institute, San Francisco. The certification program assesses products in five categories: material health, material reutilization, renewable energy and carbon management, water stewardship and social fairness. The tile product is wind, hail and fire resistant, as well as considered a cool roof, meaning it reflects heat from the sun, which reduces the need for air conditioning and provides savings on energy bills.

Working in Phases

The roofing work was completed in phases as La Casa, The Club at Encanterra was being built. “Anytime you do a project of this size, the general contractor has scheduling demands that add to the difficulty, especially when you’re working in stages and
they want you out there as it’s being built rather than all at once,” Schwoerer states. “Their version of what’s roof-ready versus what’s actually roof-ready is one of many things that causes a roofing contractor stress!”

Century Roofing’s five-man crew began by installing the spray-foam roof on the low-slope portions of the building, which compose 130 squares of the total roof area. Although spray-foam roofs in Arizona typically are 1-inch thick, the club’s roof is 2-inches thick to achieve additional R-value. The foam was sprayed directly onto the wood deck and two base coats were applied before the final topcoat, which features a #9 crushed marble cast into the wet topcoat by hand.
