LEED Certification Takes the Lead

Green building now accounts for nearly one-third of new construction in the United States, up from 2 percent in 2005, according to McGraw-Hill Construction.

The key to being green is being LEED certified. LEED stands for Leadership in Energy and Environmental Design. It is the green building rating system developed by the U.S. Green Building Council in 1998 to encourage environmental awareness.

Getting LEED certification can add about 4.7 percent to the cost of a project, according to studies by the University of Michigan. But for many businesses, getting LEED certification is worth the expense, says Andy Hoffman, a professor of sustainable enterprise at Michigan.

"They created a cachet around the LEED certification," he says. "And they got people to want to do this as a marketing pitch — and I think that was really a stroke of genius to get a rather inertial industry to start to shift."

How energy efficient are "Xenon" halogen bulbs in light fixtures?

Answer

-->

David Bergman’s work balances pragmatism with green principles. When consulting homeowners, he focuses on what he calls the “three S’s” – saving money, saving health and saving the planet.

Throughout his 25 years of experience, he has taught at Yale and currently teaches sustainable design at Parsons School of Design.

Bergman talked to Pushing Green about his career and even offered up some DIY advice for homeowners.

Pushing Green: Have you always been in architecture? What influenced you to enter the field?

David Bergman: I suspect it was a plot of my mother's. I had virtually every construction toy that existed in the sixties.

PG: How did you go about founding your own firm? What was the inspiration?

DB: I have to give a lot of credit to the firm I worked for through most of the eighties. It was a small office that had the rare combination of great design, great people and a positive working environment. After that experience, I couldn't find an equal place to move on to.

PG: Green principles are integral to your projects. How so?

DB: The one big drawback to the projects I worked on in the eighties might have been that they were not "green" - It wasn't the fault, really, of that firm though. In the eighties, there was much less environmental awareness, and there were also far fewer eco materials and systems to work with. The result of that, too often, was ecodesign that came out looking like crunchy granola. If you were a modernist, going green was pretty difficult. As the ecodesign movement started to take root in the nineties, the potential for incorporating environmental aspects without compromising esthetics expanded.

With no tradeoff for going green, I began to work it into all my projects, even when clients did not request it. "Stealth green," essentially. And with those clients who did request a green project, we could take it even further.

Integrating ecodesign into a project means not simply specifying some recycled materials or no-VOC finishes. It has to include looking at how the building (or apartment) works as a whole, almost as if it is an organism, a system -- which in a sense it is -- with inputs and outputs. How does it function in terms of water and power consumption? Ventilation? Indoor air quality? So we're looking at more than the superficial areas.

PG: The U.S. Green Building Council's only been around for over 15 years. How has your firm been affected by its development?

DB: A large part of the growing unawareness of green building design is due to the USGBC and to the evolution of the LEED program into a virtual industry standard. There are downsides to this as well, but LEED has given us – and the public – something to latch onto and to gauge by. It has popularized ecodesign.

PG: Clearly, the building industry's attitudes have changed over the last few decades with regard to "green" attitudes. Where does David Bergman Architect fit into the scene? Do you view the green movement as a "fad"?

DB: The first round of environmentalism, going back to the sixties, did indeed turn out to be a fad that abated when oil again became cheap. But this "second wave" builds upon more than oil prices and a generalized fear of pollution. Fuel prices will continue to be an influence (no one expects prices to go anywhere but up) but now we have the added combination of an issue (climate disruption) that could conceivably destroy humanity, with issues that threaten both our pocketbooks and our personal health.

With that in mind, when I talk about green design with my clients, I often refer to the three "S's": saving money, saving your (and your family's) health, and saving the planet. Most people can relate to – and see the importance of – at least one of the S's.

PG: When performing remodels, what (flawed) traditional design methods do you come across most often? Which ones pose the biggest obstacles for you as a designer?

DB: There's a tendency to think of ecodesign merely in terms of using some recycled materials or maybe some bamboo. While the materials aspect is important, ecodesign involves far more than that. It is definitely more than skin-deep.

One of the major obstacles is in enabling people to look at design and construction expenses in the long term. A frequent complaint is that green building is more expensive and, yes, sometimes it costs more initially (though not always). But often those upfront costs are recouped over time in the form of lower utility bills, lower medical bills, more durable homes, etc.

PG: What are some new developments in this field? What are people looking for these days?

DB: Some of the most exciting developments are the ones that you don't see or that enable an eco building or house to look pretty much like any other structure. For instance, building integrated photovoltaics allow us to generate solar power without putting ugly appendages on the roof.

Lighting is another hot area. For a while, the only energy efficient alternative to incandescent lights was fluorescent, which has several real a

s well as perceived drawbacks. As LEDs, OLEDs and other technologies evolve and their prices fall, not only are we going to save energy, but we're also going to have some really cool new ways to make light and light fixtures.

PG: Any advice for DIY enthusiasts within the Pushing Green community?

DB: Look at the long-term picture. Don't put in something like solar panels just because they're cool or getting a lot of attention. Do your research and do the math first. You might be better off doing something unsexy, like insulation or new windows, first.

Oh, and ask a lot of questions. Be a skeptic, particularly when it comes to manufacturer claims. There's a lot of good stuff out there but there's also a lot of greenwash.

PG: What's your most memorable project?

DB: The next one!

PG: What are some projects you're working on now?

DB: I'm just finishing a home renovation in which the client knows they will be moving and selling the house in six years. We had to make some difficult decisions in terms of construction cost versus resale value and operating costs, and a few green aspects that either were "risky" for resale or had a longer payback period had to be axed.

It's not new technology, but it was the first house that I was able to equip with solar thermal panels. They heat the pool and, compared to heating it electrically, were a no-brainer.

Thanks David! For more information, please visit Bergman's website.

Energy Efficient Upgrades Yield Valuable Tax Credits

This Old House, Better Than New

Recently, I found my home of the future. Or, what it might be if I started from scratch and had $4 million to spare.

This "New American Home" was showcased at the International Builders Show in Las Vegas earlier this year and boasted plenty of cosmetic perks -- from a luxe roof deck and outdoor kitchen to a master bath with a spa-like tub featuring changing colors and music. But it was the less glam stuff hidden behind the walls (and on the roof and in the basement) that I coveted most. The house's thermal shell was toasty: thick spray foam insulation under the roof deck, and exterior walls constructed with air-tight insulated concrete. The hot-water system was tricked out with tankless water heaters and solar technology to let the sun heat the swimming pool, as well as provide electricity. And an internal home-automation system ran the TVs, stereo and security systems from one central interface -- or an iPhone.

It's a far cry from the 1978 post-and-beam construction I bought six years ago with its power-guzzling old appliances, analog TV roof antenna, sagging pieces of fiberglass insulation and door frames leaking so much air in the winter that the dog's fur ruffled when she walked by. Back then, "energy efficiency" and "green" building were still environmentalists' lingo and housing prices seemed like to only go up.

Today, the median age of the American home is 36 years, according to the U.S. Census Bureau, and like millions of others, I'm in the midst of "future-proofing" my house so it doesn't become an edificial dinosaur amid fast-changing new building science and a hemorrhaging home-sales market. New regulations, like California's recent move to reduce formaldehyde emissions from composite wood products such as those used in kitchen cabinets, are contributing to the urgency and sparking established manufacturers to transform product lines. Financial incentives are helping too, from "green" homeowner-insurance policies to expanded tax credits for energy-efficient home improvements in the new federal economic-stimulus package.

And these dwellings aren't just for the wealthy: The average new green home is 2,477 square feet and costs $296,600, according to a recent study by McGraw-Hill Cos. Spending a bit more on such upgrades can pay off in immediate energy savings and a higher resale price down the road. One-third of home buyers say they are willing to pay a premium of $20,000 or more for a green home, according the study.

"Five or 10 years ago, people didn't wonder, 'What can we do to insulate or what sort of lighting to use to save energy?' " says Gary Drake, owner of Los Angeles-based Drake Contractors Inc. "It was more like, 'Why am I spending all this money on insulation?' "

Now, Mr. Drake estimates, a quarter of his remodeling clients request energy-efficient lighting and appliances as well as paints and cabinetry built with fewer volatile organic compounds (VOCs), solvents that can cause environmental and health problems. He is currently remodeling his own home with low-energy LED (light-emitting diode) lights and nontoxic denim insulation (like what's found in blue jeans). "I know when I go to sell it these are all things I can say I did. And I'll know I can get top dollar for my house," he says.

The house of the future -- if you started from scratch, with $4 million.

re five remodeling "future-proofing" tips experts recommend. Before you.

1. . . . Tear down sheetrock or take off siding.

Figure out where you can beef up insulation, particularly in exterior walls, basements and attics. Today there are multiple forms of insulation, many promoted as "green," including soy-based foams, loose-fill cellulose (recycled newsprint) and denim. Go for the highest R-value (thermal resistance) -- typically, the bigger the number, the better the insulation -- you can afford and fit with proper installation.

Batt or blanket insulation is often cheapest; fiberglass is still widely used. The main drawback is that batts must be trimmed to fit around pipes and fixtures, leaving spaces susceptible to air leaks.

Loose-fill insulation made of fiberglass and cellulose can flow better around wires, pipes and other obstructions. Spray-in, expanding foam insulations do a particularly good job at this and don't settle or sag over time, though are often pricier because of the materials' high R-values. Many are urethane-based but some now substitute petroleum content with soybean material. "Fill the cavity any time a wall is open," says Bruce Harley, author of "Insulate and Weatherize."

BioBased Insulation (www.biobased.net) and Soy Therm (www.soyol.com): soybean-based spray urethane foams with low or no VOCs.

air krete (www.airkrete.com): a lightweight spray foam made from cement, air and water, containing no CFCs or formaldehyde.

GreenFiber (www.greenfiber.com): a blow-in insulation made from 85% recycled-paper fiber.

SafeTouch (www.building.dow.com/na/safetouch): fiberglass-free batts made from non-irritating polyester fibers.

2. . . . Replace kitchen cabinets.

Inquire whether materials contain added urea formaldehyde, which is used in the adhesives of certain pressed-wood products, including those used to make kitchen cabinets. Formaldehyde has been classified as a human carcinogen by the World Health Organization and the National Cancer Institute recommends that "buyers should ask about the formaldehyde content" of such products.

The Formaldehyde Council Inc., a group of formaldehyde producers and users, says that at the low levels to which people are exposed there "is essentially no risk" and that formaldehyde-based products are harmless when used as directed. However, starting this year, California began regulating formaldehyde emissions from composite wood products sold in the state.

More mainstream wood-product manufacturers are adjusting product lines. Armstrong World Industries Inc. is developing a line of cabinetry boxes with no added formaldehyde.

Columbia Forest Products Inc., a large manufacturer of formaldehyde-free hardwood plywood, has organized a network of green fabricators to make it easier to find products like cabinets and furniture built without formaldehyde. "Consumers are asking for products that don't emit VOCs into their kids' rooms or kitchens, and that are made with environmentally accountable materials," says Todd Vogelsinger, Columbia Forest Products' director of marketing.

Resources:

Kitchen Cabinet Manufacturers Association Environmental Stewardship Program (www.greencabinetsource.org) lists makers who embrace practices that benefit "the environment and society."

Neil Kelly Cabinets (www.neilkellycabinets.com) and Breathe Easy (www.breatheeasycabinetry.com) make cabinetry with some formaldehyde-free materials.

The EPA's Web site discusses formaldehyde (www.epa.gov/iaq/formalde.html).

3. . . . Buy a new hot water heater.

Meantime, a growing number of homeowners are enlisting the sun to help heat their water. U.S. installations of solar water-heater systems nearly tripled between 2005 and 2007, and some states, such as Hawaii, are beginning to mandate them in new homes. What's more, residential solar water-heating systems can qualify for a 30% federal tax credit, while qualified tankless hot-water heaters can earn up to a $1,500 federal credit; there also may be state incentives.

Resources:

Find information on federal and state tax credits and rebates for renewable-energy and energy-efficiency options (www.dsireusa.org).

Find certified solar installers (www.findsolar.com).

Energystar.gov lists manufacturers of energy-efficient tankless water heaters.

4. . . . Build a new media room.

Make sure it's designed to meet the future of home technology. Can wiring support a centrally located media-distribution system that feeds Internet access, movies, games and music to the rest of the home? Can you control lighting, security, and heating and air conditioning from a touch screen or remotely from a cellphone or PDA?

Gone are the days of just making sure you have enough outlets to run the stereo, TV and DVD player. Fast-advancing home-automation technology in every aspect of life means one day, refrigerators and other appliances will be more efficient and interconnected to relay problems to homeowners or central repair databases. General Electric Co., for one, now sells an Energy Monitoring Dashboard (www.ge.com/yourhome) that tracks home indoor energy and water consumption and emissions, and can be integrated with solar technology, thermostats and music to pipe throughout the house.

With 76 million baby boomers beginning to approach retirement, home tech will increasingly communicate with outside health-care providers. And it all will require proper planning and wiring to prevent information overload. While the upfront costs can be more, it can pay off to hire an electronic-residential-design pro to plan along with your contractor.

Continental Automated Buildings Association (www.caba.org), a not-for-profit industry association, is dedicated to intelligent home and intelligent building technologies.

5. . . . Paint a wall or refinish the floor.

Products that contain few or no volatile organic compounds (VOCs) are one of the fastest-growing segments of the $21 billion paint and coatings market. VOCs are solvents that disperse into the air as paint dries, and have long been used to help it spread evenly and adhere to surfaces. But VOCs, which are largely responsible for that new-paint smell, can contribute to smog as well as kidney and liver damage, respiratory and memory problems and other illnesses, particularly in children. While you don't need to rush out to repaint if your walls are in good shape (most VOCs dissipate after 30 days), home buyers increasingly are asking if these coatings have been used in residences. Plus, low-VOC paints are generally healthier for your family while painting is going on.

They typically cost the same as regular paints or just a few dollars more per gallon. You can also find low-VOC water-based urethane finishes for wood flooring. Some states, such as California, have already strictly limited the VOC emissions of paints sold there, and the federal government is expected to propose tightening its restrictions later this year.

Ski Areas Stay Healthy with Green Energy

By Nancy Ness

In his recent State of the State address Governor Paterson said “Energy has become too expensive, too unpredictable, and too damaging to our environment. It is time to control the cost of energy and how much we use. It is time to make New York more energy independent and more energy efficient, to develop our own sources of clean and renewable energy, and build new statewide systems for energy generation, transmission and distribution.” To achieve these goals, Governor Paterson’s plan calls for New York to meet 45% of its electricity needs through improved energy efficiency and clean renewable energy by 2015.

 Realizing the potential global warming problem could reek havoc on ski operations, the NSAA (National Ski Areas Association) launched a Keep Winter Cool program in 2006. Currently more than 60 ski areas across the country are investing in renewable energy to do their part in the fight. In NY, Gore Mountain, Holiday Valley, Hunter, Whiteface and Windham are offsetting part of their costs by buying clean energy from the grid.

The first mountain resort in North America to install a wind turbine is Jiminy Peak. The turbine fills approximately 33% of the resort’s annual electrical use and almost 50% in the winter season. It will receive $47,000 yearly in tax credits. In addition, the resort expects to write off the cost of the turbine, within six to seven years. Jiminy is a model for the perfect marriage between energy needs, good location and clean renewable energy provided by the wind turbine. Wind power will provide Jiminy with stable energy costs for 25 years. Jiminy’s wind turbine, named Zepthr, is 386 feet tall and has become a tourist attraction.

In 2005, The Adirondack Wind Partners, a joint venture between Reunion Power LLC and the Barton Group announced plans for a wind turbine project called the Adirondack Wind Energy Park at Gore Mountain. The proposal calls for ten utility sized wind turbines about the height of Jiminy’s Zepthr. Each turbine will require about one acre of space. The turbines are to be placed on an industrial zoned abandoned mine which is adjacent to the Gore Mountain ski area. Although the energy will not go directly to Gore ski area, it is clean energy that they can purchase.

Adirondack Wind Energy Park could employ approximately 75 people during the construction period and have two to three permanent full-time technicians. The project offers an excellent wind resource, minimal land alterations, an existing assess road network and existing transmission lines.  The transmission line is capable of serving the project and connects with the substation in North Creek. The proposed wind farm could supply up to 14,000 New York homes for one year (over 50% of Warren County homes).

The company is currently collecting weather data, and will study how birds and bats occupy the area before making final applications for permits. Once the project is designed and impact studies are complete, the development can move into the slow permitting phase. However, Bill Thomas, APA Commissioner, feels that given Governor Patterson’s directive for renewable energy by 2015, it makes sense to put APA clean energy approval projects on a fast tract.

Opposing the project, The Association for the Protection of the Adirondacks and the Adirondack Council say their reasons range from aesthetic concerns to setting a poor precedent. Their fear is that if the Adirondack Park Agency were to permit large wind turbines on the Park mountain summits, dozens of wireless communications companies will want permission to erect lower structures They also feel the Adirondack mountaintop is not an appropriate place for industrial-sized windmills because they would destroy the park's natural beauty. Opposition groups also have concerns about impacts on wildlife that would come into contact with the turbines' rotating blades.

The best answer to these concerns comes from Greenpeace Executive Director John Passacantando who said in a letter supporting the project "It is our belief that any environmental impacts caused by installing these wind turbines will be minor, especially when compared to the truly profound impacts of global warming on ecosystems across the globe,". The Adirondack Wind Energy Park project has the support of  Warren County’s Conservative Party, Democratic Party, Independence Party, Republican Party, Warren County Board of Supervisors, Gore Mountain, Adirondack Park Local Government Review Board and many more organizations.
