Austin, Texas builder Clark Wilson has been in the homebuilding industry for over twenty five years, serving as president of Doyle Wilson Homebuilder, Inc. and then as CEO of Clark Wilson Homes, Inc. before retiring in 2002. Eager to get back into home building and aware of the growing demand for green homes, Mr. Wilson took over a small company named Green Builders, Inc. in 2007 with the goal of turning it into the largest builder and developer of green homes and communities in the United States. Only a year old, Green Builders, Inc. has already won the award for 2008 Single Family Affordable Home of the Year by the National Association of Home Builders.

When considering his return to home building in 2007, Mr. Wilson decided that the world did not need another behemoth home builder. “Austin is a hotbed of green,” said Mr. Wilson. “We’ve had green building programs since the 80s. With Green Builders, Inc., we wanted to bring green building to the masses.” By shifting building priorities toward saving money through energy and water savings, and by seeking out environmentally friendly products that don’t drive up the price of the home, green building has made traditional non-green building, in Mr. Wilson’s estimation, obsolete. “We’re priced competitively to non-green builders. They’re going to have to catch up. Green building needs to be widespread. We want to position ourselves as the Whole Foods of homes.” Read the rest of this entry »

I don’t know how you spent your weekend, but we spent ours with hands outstretched, feeling for hot, attic air shooting out of electrical outlets, ventilation fans and air vents. After months of crazy-high electric bills, we decided to get to the bottom of why it was costing so darn much to cool our rather small home.

Enter the HERS Rater (Home Energy Rating System).

It turns out there are wonderful people who will come to your home, put up a strange looking contraption called a “blower door” on either your front door or entry to the attached garage. A fan is turned on, the pressure is measured (our house was brought to -50 Pascals) and the cubic feet per minute of air that is rushing out of the house is measured.

Let me first preface this post with the following: I’m not a construction professional. I’m just a curious homeowner seeking out the best building materials for my home. With that said, I was familiar with three options in residential construction - concrete block, wood frame or the super green alternative, rammed earth.

Turns out there are new options that combine the wonderful qualities of Portland cement with recycled post-consumer plastics (Rastra) or recycled wood fibers (Durisol).

The iconoclastic owner of the San Jose tract home featured in this article takes exception to the notion that green is expensive.  Green, to him, is rooted in conservation of all resources, not the least of them being money.

Frank Schiavo’s compact, tract-built, three-bedroom ranch-style home in a modest San Jose neighborhood demonstrates that remodeling to create a cutting-edge green home is neither difficult nor expensive. Heated with sunlight and cooled by night air, his home is comfortable, quiet and tasteful, filled with light and local art. With only modest investments in a sun room, extra insulation, new windows, a very small array of rooftop photovoltaic and solar hot water panels, his electricity bill for the coldest, cloudiest months of the year averages a few dollars a month. His gas bill is even more modest.

What’s most impressive about Schiavo’s house isn’t that it’s so comfortable and practical for him to own, it’s that it demonstrates that lofty resource conservation goals can be achieved on a modest remodeling budget.

Author’s note: the following article on home heating is the first in an eight-part series. The series specifically targets climate found in the San Francisco Bay Area, but has applicability elsewhere.

According to the U.S. Department of Energy, heating and cooling amounts to 46% of all energy consumed by our homes. Water heating uses another 14%. In coastal California, where extreme heat is rare and winters are mild, a properly sited, well designed passive solar home can generate its own heat and hot water, and do without air conditioning.

Historically, few homes are so well sited or built. Since our area has more heating days than cooling days, most homeowners need a heating system. What few know is that many indoor air quality problems can be by-products of forced air heating, ventilation and air-conditioning (HVAC) systems installed in their homes.

Yes, most of this list refers to the Brit series Ab Fab but if Eddy and Patsy turned in their smokes and cocktails for organic and sustainable munchies then they too would be excited for the opening of the Epi Center MedSpa, the first LEED certified MedSpa in the country. (Another LEED spa exists in D.C. but it isn’t a MedSpa). So, because fictional characters from a long ago Brit TV series couldn’t check out this just opened San Fran based spa, I decided that I had to do it. Read the rest of this entry »

On Tuesday, April 22, the Sundance Channel will present as part of their The Green series “The Greening of Southie,” a documentary on the construction of Boston’s first green residential building, the Macallan, which is seeking a LEED gold rating. If the idea of watching a documentary on the construction of a condo building doesn’t sound too exciting to you, I cannot recommend this film enough to anyone who is or wants to be a part of green building. It presents the challenges and excitement of building green with equal measures of idealism and cynicism, juxtaposing the suits who see the project as ideas and paper with the laborers who actually have to put the building together. As the project grows, the two come closer to understanding the other side.

Fittingly, the film begins with a group of incredulous workers in hard hats listening to a project manager describe what a green building is. It turns out he doesn’t exactly know himself. “What does it give you?,” “what’s the point?” they ask. “I can’t answer that exactly,” he responds. But the skeptical laborers make jokes, dismissing the whole idea. After the manager explains that the condos will have “double flush” toilets, one man jokes, “I use that a lot - that system. One never seems to do the job.” Read the rest of this entry »

Green roof manufacturers incorporate sustainable products beyond the greenery.

If it looks green, smells green and feels green, it must be green. Right? The answer, it turns out, is more of a maybe. It is common knowledge that green technology has large positive environmental impacts: large-scale energy savings, run-off reduction and heat reduction among their chief assets. But as green builders continue to define the standards and guidelines for sustainable construction practices, different levels of earth friendly products continue to circulate the market. Green roofs in particular are taking a harder look at the sustainability of their component materials.

Make it last
Brad Budde of Conwed Plastics, Minneapolis, Minn., believes the future development of sustainable green roof products lies in the hands of builders. He suggests that as companies continue to understand the commercial concerns regarding the application of sustainable and earth friendly products that the market as a whole will become more educated about their applications, benefits and uses.

His company is a leader of earth friendly, compostible packaging materials as an alternative to traditional plastic bags, as well as biodegradable plastics that don’t leave the harmful, long lasting resins of other industry plastics. “It’s a really great product that solves some of the disposal concerns for traditional plastic products,” he says.

Building with Awareness is an interesting package loaded with information. It is a DVD with an accompanying book (or a book that comes with a DVD included, depending upon how you look at it). The two nicely complement one another in a fairly unique way. The story contained in the DVD documents the construction of the author’s own small (800 sq. ft.) home built in Albuquerque, NM. The book goes into more detail about the solutions and approaches that are taken in the construction of this home. Together, it is a very instructive combination which showcases a number of sustainable construction methods used in this project.

The book does not try to be all things to all people. It documents a specific project and shows how specific procedures were used in it. Everything, from preparing the subgrade and the foundations, to installing the roofing and finishing the walls, is covered. The extensive nature of the coverage is useful not only in demonstrating how to execute the various parts of the construction, but also how the parts work together and complement one another.

However, while it shows how these methods and materials were used, it does not go into such sufficient detail that it should be taken as a how-to or a do-it-yourself guide, at least, not without some additional information. The book does contain reference points that show where in the DVD they are discussing a particular material, technique or decision. This allows the reader to readily turn to the video presentation and match it with the information presented in the book. Reading about a type of construction and then seeing how it is demonstrated is a useful conjunction of two different forms of presentation. Read the rest of this entry »

Here in the Bay Area, it’s not just Berkeley who’s showing Green Big Brother mentality. Green home building will be required from all new homes built in the unincorporated region of San Mateo County. The county supes this week voted to add sweeping green regulations to green construction requirements to take effect later this year.

The new regulations will cover homes and industrial projects. The Green commercial and industrial buildings can pass under the LEED system while residential properties can be gauged under Build it Green’s “Green Point Rated” system. Green Point Rated, a residential, Green rating system created by the Berkeley-based non profit, uses various point categories to achieve certification. For example, installing a range of Energy Star appliances is worth nine points and using low VOC paints and wood-coatings can garner six points. Homeowners can combine various point categories, as long as they add up to the magic 50 point total.

To be fair, this program does have its costs. Homeowners will have to pay a specialized green building inspector to verify their project for the county which will set them back about $800 to $1000, and for commercial owners it will cost from $2500 to $3500. Applicants will also be required to post a $5,000 bond prior to receiving a building permit, which will be released when the 50 points are verified.

Although I like this program, it does have shortcomings, however, such as not affording homeowners the incentive to obtain more than 50 points. Many people find the same issues with LEED rating system. People may think, “Why should I try for 60 points if it’s just going to cost more?” Home and commercial building owners may try for more points without considering the up-front cost, but it wouldn’t be a bad scenario if the County of San Mateo offered further incentives for higher points.
