BuildingGreen’s Top 10 Green Building Products of 2010
Did you attend Greenbuild this year? It was recently held in Chicago’s sprawling McCormick Center, and was a colossal event that brought together people from various parts of the world. For us, our days there were packed with educational sessions, time on the expo hall, [...]

The first full day of sustainable building material tours got off to a rocky start. I awoke to discover that my bank and auto insurance company hadn’t been playing well together for the past three weeks. As a result, I was on the road, with a rental car, and without auto insurance. I never [...]

“This movement is all about collaboration.” So said Tammy Schwolsky, CEO of Residential Energy Assessment Services, Inc. (REAS), while giving us a sneak peek at her ZENERGY House the day before its grand opening (we covered that event here). Kevin had asked her what single aspect had surprised her the most during the two-year house renovation project, and without hesitation she said that it was how everyone really needed to work together to accomplish truly sustainable results. We encounter that sentiment quite often in our conversations with artists, designers, fabricators, and all the other professions whose practitioners are actively working in the sustainability movement. Yet of everyone we’ve talked to and worked with, few individuals embody that sentiment better than Robyn Palmen, Architectural Sales Manager at Interstyle Ceramic & Glass.
Several years ago, when we started looking for recycled glass tiles, our knowledge of that entire category was rather limited. We were very much still learning what questions to ask manufacturers about their products to determine whether or not they would support our pursuit of sustainable strategies. We found Interstyle right at that time, and from the onset Robyn was welcoming of our inquiries, enthusiastic about keeping us informed about new developments, and mindful to check in with us often to make sure we were well stocked with samples and product details.
I realize that you may be reading this and thinking, “What’s the big deal? That’s her job.” And all that may be trivial, but I often found that, in reaching out to other companies, I usually hit a brick wall: messages were never returned and e-mails went unanswered; or if I did manage to speak with someone, I would either get vague answers or be promised information that later would not be delivered. A few months ago I wrote a little about an experiment that Interstyle did for us (read that post here). It was Robyn who took our design specs and got that sample through their shop, all before we ever specified any of their tiles. Now, this post is not about Robyn specifically, but I find it difficult to speak of Interstyle without mentioning her because, to us, her approachability is a reflection of the company, their values, and their integrity in the sustainability movement. And when we combine that with the incredibly beautiful products that they design and manufacture, we must admit that we are huge fans – we just love what we see.
Insterstyle Ceramic & Glass is a family-owned company based in Burnaby, British Columbia, Canada. It was founded in 1977 by Ernesto and Georgia Hauner. The Brazilian husband and wife team had once ran Mobilinea, a modern furniture company. Their emigration to Canada had forced them to leave that company behind. Once in British Columbia, they decided to delve into the world of ceramic tile and, thus, continue their entrepreneurial proclivity in their new home.

Some of the most interesting developments today in sustainable building materials might be occurring at offices and laboratories within federal agencies. One example is the Forest Products Laboratory (FPL) in Madison, WI. This century old government lab, operated by the U.S. Forest Service through the U.S. Department of Agriculture, has conducted remarkable scientific research on wood products and their potential commercial application. During the late 1980s a research general engineer named John Hunt began experimenting with dimensional fiber products. His primary focus was wet formed molded hardboard panels made from bio-based low yield wood, recycled paper, and agro fibers. His ground-breaking work led to a number of commercial products with names like Spaceboard and Gridcore.
In 1992, Robert Noble created Gridcore Systems International (GSI), licensed the patented Gridcore technology from the FPL, and developed a business plan to commercialize the proprietary process of molding cellulose fibers into three dimensional structures to create high performance panels from recycled resources. Although an interesting and unusual material, Gridcore was not the first, or only, product of its kind. It’s lineage can conceptually be tied to similar products made from pressed straw, wheat, paper, and byproducts of agriculture.
Seven years after its founding the company shuttered their Long Beach, CA manufacturing facility and halted production. “We made a strategic mistake in trying to position the product as a commodity product to compete with others such as plywood and MDF,” says founder Robert Noble during a recent interview, “and attempted to compete with those on price.” Engineered wood panels live in a category where price alone typically drives purchasing decisions. GSI found it difficult to communicate the environmentally favorable attributes of their product in such a selling climate.

On Friday, April 2, the ZENERGY House prototype opened to the public. It was the culmination of years of work by Tammy and Ron Schwolsky, co-founders of Residential Energy Assessment Services (REAS), an energy auditing and consulting company, and the beginning of a living laboratory where the Schwolskys have put every energy efficiency product and strategy in the house to the test, and use the process as a teaching opportunity for the local community.
Tammy tells us that she and Ron, both energy auditors, bought the house in 2007 with the original intention to do a whole house energy efficiency retrofit and put it back on the market within six months. They hoped to use the project as an example to builders and homeowners that a market demand for high performance homes does exist. Unfortunately, their timing could not have been worse. They realized they wouldn’t be able to sell it, so they modified their strategy. Their work had already shown them that it’s sometimes difficult to get people to change long-lived behavior related to buildings if you can’t show them a better way in practice. So, they began to re-envision the house as a tool for them to teach and for others to learn about how to “green” existing homes, getting it to be as close to net-zero energy as possible.

The house was specifically chosen for its size. At 2,450 square feet of living space, it represents the average size of a single family home in the United States. It’s a one story structure with a large entry area, a living room, a kitchen with a small eating area, three bedrooms, three bathrooms, a tiny sitting room, a two car attached garage, and an outdoor pool. Built in 1950, it was hardly a model for energy efficiency. An exhaustive energy audit made use of a blower door, duct blaster and infrared camera, combustion analyzer, and only after knowing the state of the house did the improvements begin. Some of the more notable improvements are:
- All windows and most of the fixed glass block installations were replaced with dual-pane low-E windows.
- Lighting needs were reduced by 30% and all incandescent lights were replaced with CFLs and LEDs.
- All three existing toilets were replaced with dual-flush toilets for water savings and consumption was reduced by 70%.
- A new water heater clocking in at 99.1% efficiency replaced an older model.
- The original 2 3-ton A/C unit and 2 furnace HV/AC system was replaced by a single, new 3-ton A/C unit and combined hydronic heating system.
- New, Energy Star qualified appliances were installed.
- Once all other energy efficiency strategies were exhausted, a set of 12 photovoltaic panels was installed on the west-facing roof. The system is visibly tiny; it takes up less than half of the west-facing roof space, and operates at a 17% efficiency level. Yet, despite all that, the energy requirements of the entire house are so small that the system can easily handle the demand.

In 2004, on a busy corner in Venice, CA, an old Hudson auto repair garage built in 1923 was converted to an art gallery. Abbot Kinney Boulevard, between Venice and Pacific, is a ten block long collection of trendy restaurants, custom jewelry shops, book stores, clothing stores, and consignment shops. Every medium-size U.S. city has a similarly gentrified stretch. The garage was located at the southeastern end of that stretch at the corner of Venice and Abbot Kinney. Others in the community may not have given much notice to yet another gallery opening in an already artsy neighborhood. However, it was the first time the garage had been used for anything other than auto repair since it had been built. The new tenant and planned space were different, yet not in a way immediately obvious, especially to that tenant. epOxybOx (intentional spelling) was an art gallery dedicated to presenting green art and the work of fine artists using green materials or media. That idea may have been several years ahead of the curve, but that’s not what set it apart. At the time, no one could have predicted what it would become and how it would evolve.
When Deborah Guyer Greene started epOxybOx, she wasn’t fully aware of the path it would take. In fact, her new venture began on a bit of a lark. She was art director for the Foliage Theater Project and ran the Shakespeare Probation Program where she taught theater to violent offenders between 14 and 19 years old. One day, while searching for a large wall surface for a mural painting, she stumbled on the shuttered garage. She knew as soon as she saw the place she had to do something with it. During a recent interview, she referred to it as divine intervention. “It’s a terrible way to make business decisions,” she warns. Without a written business plan and before securing investment capital, Deborah signed a lease and formed epOxybOx. It quickly became a social hub, a community gathering place, an event center, and a place to party. Event and opening audiences went from small crowds to large throngs.
While converting garage to gallery, Deborah knew she wanted to use environmentally favorable building materials, but finding them was far more difficult than she expected. That struggle planted a seed in her mind. Two years later she joined forces with Sasha King to form epOxyGreen. Their idea was that green materials should be easier to find and affordable to purchase. At first they carved out 500 square feet in the garage lube room, but the new business was an instant hit and required additional space. As the showroom grew, the gallery shrank. It eventually took over all 1,500 square feet.

On July 27, 1976 members of the American Legion gathered at the Bellevue Strattford Hotel in Philadelphia, PA to celebrate the American Bicentennial. Within two days, veterans were falling ill with an unidentified ailment with symptoms similar to pneumonia. By the end of the event, more than 220 attendees had been treated and 34 eventually died. A six month investigation by the U.S. Centers for Disease Control and Prevention finally uncovered the culprit – a bacteria breeding in a hotel cooling tower.
I grew up in New Jersey less than 60 miles from Philadelphia. I vividly recall my excitement for the 1976 American Freedom Train and the Bicentennial summer, along with my fear over what would later be named Legionnaires Disease. There was great debate at my school about whether a scheduled field trip to a Philadelphia museum would be canceled. My mother tried to reassure me that it wasn’t as bad as it seemed, but I knew something was wrong. This incident also had a profound effect on Carol Baumgartel, founder of American Clay. During a recent interview conducted in the LEED Platinum certified home of a good friend she told me how it forever altered her thinking and initiated a heightened sensitivity to the presence of toxic substances commonly found in the average indoor environment.
In 1999, Carol’s oldest son Croft developed skin reactions, headaches, and respiratory conditions from prolonged exposure to caustic chemicals he used with his fine interior finishing business. Around the same time, a colleague introduced him to a European clay plaster product that was free of the potential toxins affecting his health. Although it was an improvement, he thought he could make it better. He enlisted Carol, an interior designer with a fine arts degree in ceramics, to research the product and determine its composition. With her understanding of clays and aggregates and his engineering background they were able to reverse engineer a comparable product.
We should not underestimate the potency of mixing maternal instinct and entrepreneurial spirit. In my interviews with product manufacturers, I’m often told how underlying considerations for future generations influence business decisions. When I raise this issue with Carol it brings her to tears. It’s easy to see how deep her passion runs for merging her business strengths with efforts that contribute positively. Regard for others, even people you don’t know or will never meet, is an essential ingredient of sustainability.

When I was a kid my father occasionally took my brothers and me to watch military aircraft take off and land. He knew of a road that cut through what was an FAA tech center near Atlantic City NJ known as NAFEC – the National Aviation Facilities Experimental Center. At the time, it had the largest hanger space in the world, was the third alternate landing site for the space shuttle, and was the location of the first airshow in 1910. We would pull the family station-wagon to the shoulder of the road right at the end of the main runway and watch the planes for hours. The jets seemed so close we could touch them. My fifth year architectural thesis project was a flight school at the community college directly adjacent to that former FAA tech center – it had been converted to the Atlantic City International Airport by then. Part of my design strategy included using salvaged aircraft parts as raw building material. The reviewers who attended my final presentation thought the notion was preposterous.
The Davis-Monthan Air Force Base in Tucson AZ is the world’s largest military aircraft graveyard. It’s often referred to as The Boneyard, however, boneyard is a generic term used to describe facilities that store aircraft retired from service. In nearby Pima AZ is the Pinal Airpark, home of the Evergreen Aircraft Maintenance Facility, one of the largest storage locations for decommissioned commercial aircraft. Although these two are among the largest of their kind, similar facilities exist throughout the world. The dry southwestern United States is ideal for aircraft storage. The arid climate reduces the potential for oxidation. Prior to the attacks on 9/11, anyone looking to salvage parts or components from the aircraft stored at these facilities had reasonable access. Since then, the U.S. government has changed the regulations and old parts are significantly more difficult to source.
For visionaries and artists like Dave Hall and Donovan Fell, owners of the Torrance CA-based MotoArt, new restrictions limiting access to what they see as raw material for their business means they’ve had to search for parts farther afield. But it hasn’t stopped their business from growing. Both are what I would consider glass-half-full people. They see opportunity everywhere. For more than a decade Dave and Donovan have been converting salvaged aviation components into amazing furniture that’s functional and beautiful art. Had they been sitting in on my final thesis review, the outcome may have been quite different.

Our recent trip to Florida proved the perfect opportunity to visit the showroom of Matrix Z, LLC. and meet the artist behind the company. Based in Fort Lauderdale, FL, Matrix Z was founded in 2001 by Barbara Zigann with the intent to create a sustainable alternative to quarried natural stone. Since then she has developed three lines, one a jewelry collection, with strong usage of recycled material.
The current collections are:
- SeaStone: tiles made from a proprietary cementitious mixture that incorporates 70% to 75% recycled content.
- SeaTile: tiles and laminates made from oyster and abalone shells recovered from the waste byproducts of the fishing industry.
- SeaGems: iridescent jewelry and craft assemblies using the same fishing industry byproducts.

For our purposes, we were most interested in the SeaStone collection. At first glance, it is easy to look at the tiles and think that they were mined. Their color is so natural, and the variation from tile to tile so evident, that it makes perfect sense to believe they are a completely nature-made creation. But they are not. Even though during our visit we were not able to tour the manufacturing facility, it lies within miles of the showroom, and it is the place where all of these materials are created.
