12 Questions to Ask Before Choosing a Green Building Product

A green building product better begin as a good product. Here’s what to look for before diving deeper into a product’s green claims.

By: Rick Schwolsky

green-homesWhile the industry has made real progress in providing us with green products and backing up their performance claims, product selection will continue to be one of the most critical challenges you will face in meeting your green missions—and that puts your business and reputation at risk.

As a former high-performance home builder, I know what this feels like. You’re stuck in a gray area between innovation and risk, caught between a commitment to build high-performance homes and your responsibilities to ensure those homes still perform their most basic functions without creating problems—or liabilities.

“Nobody,” builders often say, “wants to be the first to try out a new product,” and yet we’re driven to embrace change and improve the way we build. This dilemma puts pressure on every decision you make, whether it’s detailing a wall section, specifying ventilation equipment, or selecting finishes.

You have to find a reliable level of confidence in your decisions and balance the trade-offs associated with them. But how can you gain the confidence you need?

Here are the first 12 questions you should ask about any green building product you’re evaluating—before you make your selection:

How will it perform its basic function as a building material or product?

How does it compare with products I use now?

Is it code approved?

Is it third-party certified?

Will it contribute toward project certification?

Is it available?

How will it affect my pricing?

Will it increase my level of risk or liability?

How will it improve the level of performance of my homes?

How will it contribute toward sustainability?

Will it require new sequencing or installation skills/trades?

Is it worth the investment for the benefits?

After answering these 12 questions, apply your own experience and expertise to filter out products that would put you outside your comfort zone in terms of unknowns and risks.

Only after evaluating potential selections for their application as viable building products can you focus on their green attributes and performance benefits and how they’ll integrate with the other elements of your green projects. At that point you can ask: “What makes these products green?” “How can I avoid greenwashing?” and “How can I verify the manufacturers’ performance claims?”

This last question leads to third-party certifications, which we regularly cover in EcoHome.

Building to a Higher Standard

By Leave a Comment

There has been an explosion of interest in going green. Everything from cars to light bulbs are being pushed to new levels of efficiency. New industries are cropping up, it seems, on a daily basis.

But what about buildings; office buildings and schools in particular. These are the places that we spend most of our waking hours, and where we consume most of the energy.

There is a movement, led by the US Green Building Council, to establish standards to which buildings are designed and constructed by. Affecting more than just the energy consumption, but also the environment of the occupants inside. Buildings are certified, showing that it has met the requirements for a particular level of efficiency.

Not only do buildings get certified, but individuals also become accredited. There are thousands of LEED (Leadership in Energy and Environmental Design) Accredited Professionals in the United States, all of whom had to pass a fairly difficult test covering the details of the “LEED” program. These “APs” act as a guide to design a building for the specific purpose of attaining high levels of efficiency.

Just as hybrid cars are more expensive than their normal, gas powered counterparts, buildings achieving, or attempting to achieve any level of certification will have an increased cost. The cost, if calculated properly, should be offset by the reduction in energy usage, and the increase in productivity of the occupants of the building. And the payback of the additional cost could come in 5 years.

A recent study released from the venture capital firm Good Energies, Inc states that around 50% of non-residential building will be green by 2015. That is five years from now. It must also be noted that these numbers also include buildings that did not obtain LEED certification, but did adhere to the guidelines. This should be recognized as tremendous growth.

Based on the ever increasing number of buildings being submitted for certification and the growing population of accredited professionals, it looks as though green building has only barely gotten started.

Bamboo is Not Always “Eco-Friendly” to Use in Green Projects – Is Using Bamboo a Boo-Boo?

By Leave a Comment

For several decades now, we as San Francisco home owners, contractors, architects, designers and realtors have been told that bamboo is a wonderful material for remodeling projects in that it is very low in cost (relative to hard woods) and ecologically sustainable.

How many of us have attended trade shows in the San Francisco Bay area where bamboo stole the show? These trade shows tout the wonders of using bamboo for everything from flooring to ceilings, waste baskets to coffee table furniture, and even drinking cups more. The cost of many projects could be cut in one third or even one half as bamboo is far less costly (or so we have been told) than comparable hardwoods that were not as versatile nor as eco-friendly. Before the year 2000, much of these facts were true, and no one had any reason to doubt this after several decades of using bamboo for mass industrial uses in buildings.

But around the year 2000, many growers in Asia began harvesting the bamboo stalks at earlier ages than the minimum of five years growth. These younger stalks do not yet have enough strength and durability and are best used in craft projects like basket weaving or clothing. Many homeowners. contractors and designers continued recommending and using bamboo in the early 21st century totally unaware of the results to follow.

Today, in 2010, there still are large quantities of bamboo imported into the United States each year. How many of us can tell bamboo (or bamboo derived materials) that are more than five years in age? How many of us can tell bamboo that is younger than five years of age? Probably no one can. Therein lies the problem all of us face in choosing bamboo for our next “eco friendly” project! No one can tell. Well, actually we can tell after several years of wear and tear – but who would want to waste thousands of dollars (or risk thousands of dollars waiting) if the bamboo begins to decompose several years after installation?

Perhaps in several years there will be a bamboo rating system so that those of us who choose to use bamboo for its potential strength and beauty, not to mention its functionality. May I suggest that the rating system be simple to include only three categories: A “harvested at 5 years or older from a verifiable source/ documented”; B “harvested under 5 years and therefore not of durable strength for most projects”; and C “source or harvest age unkown”. In this way the buyer can have some sort of confidence up front at the start of a project that they are truly using an eco friendly material or not.

Until that time, I will continue to admire bamboo, but I will not encourage my own clients to use it in any projects expecting long term durability, nor as a substitute for hardwood flooring. Maybe it is best used only as an attractive live landscaping plant until further notice!

If you would like further information about bamboo and ways to begin a simple easy to classify system that can easily be internationally accepted, write me. My contact information is below. The first step is for a large bamboo harvesting plantation in China to start a documentation process. Documented bamboo, fetching far more in revenues (as if it were “organic produce”) will be the impetus for change. Even if change comes slowly, many home owners, builders, and designers will happily step to the front of the line for a truly certified quality building material. Bamboo deserves a place in every home. But first, let’s at least know the age of the material when harvested.

Green Homes | The Basic 10 of Green Construction Part V

By Leave a Comment

This is the conclusion of a series of articles on the basic components of good green home construction. Having covered orientation, sealing the building envelope, insulation, efficient HVAC equipment, energy-saving appliances, upgraded windows, water conservation, and indoor air quality, we wrap up with durability and certification.

9 – Durability. One of the basic definitions of a green home is one that is built to withstand the test of time. What products offering increased durability will be used to construct the building envelope? What is the expected lifespan for the roofing and siding options you’re considering? For example, the estimated lifespan of metal roofing is more than 50 years, compared with 20 years at best for shingles. According to the manufacturers, concrete and copper roofing products are expected to last a lifetime.

One of the basic principles of durability begins with moisture mitigation. What products and methods will be used to protect the home from water intrusion through the roof, the walls, and/or around the windows?

Are termites a problem in your area? What termite-resistant products and procedures will be used in the construction of your home? Metal studs, borate-treated framing, installing irrigation and foundation plants at least two feet from the foundation, and exterior termite barriers are some of the possibilities.

Selecting products with durability in mind reduces replacement and maintenance costs down the road and increases the longevity of the home.

10 – Green Certification. Now that we’ve gone over the basics of green construction, you might be wondering if all green certified homes include these features. Not necessarily. The points selected from the green certification checklist and the green certification program chosen will determine the total green makeup of your home.

Your home can be certified as green through national programs such as LEED (Leadership in Energy and Environmental Design) designed by the U.S. Green Building Council, and the Green Building Program from the NAHB (National Association of Home Builders). In addition, many states have adopted their own green building certification programs. For a list of local green building programs, visit The National Association of Home Builders. Click the button on the left side of the home page entitled “Find a Local Program.”

Three components of a green certified home:

Whole-house approach: Although there are various green certifying organizations, they all require a whole-house approach to green construction. Because points must be selected from all categories within a certification program, all areas of the home are addressed. These categories generally consist of lot/site, energy-conservation, water conservation, health, and materials.

Inspection: A green certified home also means the structure was inspected during the building process by a green certifying agent to confirm that the selected green products and procedures were implemented or installed. The agent must provide documentation to an independent third party proving compliance with all selected points. If the third party is satisfied that the home meets all the requirements, it will award a green certificate.

Testing: Another aspect of the green home certifying process involves a series of tests on the home itself. These procedures measure whole-house air leakage (the blower door test) and ductwork leakage (the duct blaster and smoke test). Thorough and proper insulation installation is also reviewed through the thermal bypass inspection. (Note that not all tests are necessarily performed on every green home.) For an explanation of these testing procedures along with photos and a video of the ductwork smoke test, visit www.onestopgreenhome.com.

Green Homes – Top 10 Benefits

By Leave a Comment

green homeGreen building is so much more than saving energy or reducing a home’s environmental footprint. Homeowners of a certified Green Home can realize many more benefits as described below.

Lower Operating Costs – Your Green Home will have lower energy and water bills as a result of energy and water efficiency measures.

Healthier Home – With improved indoor air quality, less harmful off gases and prevention of water intrusion, which can create mold, your family should be healthier, miss less work and school, which hopefully will result in less medical bills

Reduced Maintenance & Replacement Costs – Increased useful life of products and materials will result in cost savings. A properly planned landscaping package will reduce the amount of time spent working in the yard and allow more time to enjoy the outdoors.

Potential Financial Incentives – As green home building has become more mainstream, there are increasingly more federal tax credit and local government and utility company incentive rebates available, lower cost Green mortgages available and more recently, insurance companies are beginning to offer lower premium options.

Higher Performing & Durable Home – You will benefit immensely from a better built and higher performing home; 3rd party verification of duct leaks and house air leaks will insure that any deficiencies discovered can be addressed and repaired during construction, saving untold amount of wasted energy; certification experts will approve your home for your LEED (Leader in Energy & Environmental Design), NAHB (National Association of Home Builders) or other local approved Green certification programs, resulting in a higher valued home.

Environmental Friendly & Sustainable Measures – Can one family building a Green Home solve global warming or bring a complete halt to diminishing resources? No. Can one family building a Green Home contribute to the solution and be part of a movement that one day may be the new standard? YES! Through the use of sustainable practices, recycled and renewable products, and more energy efficient systems, we can reduce the impact on our environment and precious resources.

Higher Value & Resale Advantages – Your certified Green Home will have a higher value than a comparable standard home and if you decide to sell your home, multiple listing systems used by Realtors to sell homes are now recognizing green certification programs and it is much easier to market the benefits of home to buyers.

More Comfortable Home Environment – Imagine the personal benefits to you and your family by living in a quiet, clean, safe, secure and controlled indoor air quality home – is there anything more important that the health and welfare of your family? Is there really a price tag you can assign to the benefit of building a Green Home to you, your children and your grandchildren?

Safer & More Secure – Your family is better protected with the use of high performance smoke detectors, carbon monoxide detectors, radon testing detectors and security system.

Promotes an EcoGreen Luxury Lifestyle - Now that you have decided to build a high performance and healthy Green Home, your life is changed forever – all for the better! Would you furnish your new home with anything other than safe, healthy, organic and eco-friendly products? Might you consider living a healthier lifestyle? Will you sleep in peace knowing you have provided your family a safe, clean, healthy living environment?

As you can see, there are so many more benefits in owning a Green Home than just “energy efficiency” or being “eco-friendly”.
