Green Building Products

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.

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.

How Consumers and Builders Feel About Green Homes

Benefit of Green HomesHere is the reality about green homes: they reduce carbon footprints, save consumers money on utility bills, and improve the health of children living in the home as a result of better air quality and other related factors. In a society with a growing focus on environmental sustainability, green homes are not just a potential future; they’re forming a part of our present.

But the reality about green homes and what the public actually thinks about them are not always one and the same. In fact, they can be disparate enough that it would warrant continued action by organizations supporting green homes to increase awareness about the benefits of these homes and to dispel any myths.

Whirlpool Corporation is interested in seeing that green building takes hold in our society. Whirlpool has been a partner of Habitat for Humanity for years, donating ranges and ENERGY STAR® qualified refrigerators to new Habitat homes built in the United States and Canada as well as supporting Habitat’s work around the world, and engaging employees to volunteer with their local Habitat organizations. To gauge public perception on the topic of green homes, Whirlpool and Habitat teamed up with NAHB Research Center – an independent subsidiary of the National Association of Home Builders (NAHB) – to survey consumers and builders on what they think is the state of affordable and green housing in the United States. Whirlpool is releasing the results from this survey in a series, with the first set of results on the affordability of green homes released in November 2010 and the second, identifying barriers to green homes released in January 2011.

The survey found that builders and consumers generally perceive green homes as affordable to live in but more expensive to purchase. In fact, among consumers, 67 percent of high-income respondents said they believe a completely green home would be affordable to live in or maintain. The same answer was given by 65 percent of upper middle income, 59 percent of middle income and 48 percent of low income consumer respondents.

But, when asked if a green home would be affordable to purchase, only high income respondents answered mostly in the affirmative, with a total of 71 percent, compared to 47 percent of low-income respondents who said that they believe a completely green home would not be affordable for them to purchase.

The builder portion of the survey found that 87 percent believe green homes are affordable for middle-income families to live in, but 30 percent felt green homes were not affordable for the segment to purchase or build. The disparity is even more evident when asked about low-income families. A total of 70 percent of home builders said they believe green homes are affordable to live in for this segment, but almost 60 percent thought green homes were not affordable for low-income families to purchase or build.

However, the survey also demonstrated that the public is generally in favor of a continued effort for creating more green homes. It showed that 64 percent of respondents indicated that savings from green home features were sometimes worth the added costs and efforts. And, 77 percent of consumers feel that green homes are at least somewhat, if not very, important to them. And they note that green homes are important because of the positive impact on the environment, the long-term financial savings, and the health benefits for the family. It seems clear that the public believes in the importance of green homes, so what do consumers and builders believe will help them become more affordable? According to the survey, the answer lies in reduced prices on materials for construction. A total of 59 percent of consumers indicated that lower cost of products and materials is needed for green homes to become more affordable and 75 percent of builders agreed with this.

Another change consumers mentioned that can make green homes affordable is an increase in incentives for sustainable building and remodeling. Of all respondents, 53 percent felt that increasing incentives for homeowners would help with green home affordability, and 36 percent suggested increasing incentives for builders. In addition, 69 percent of consumers indicated they believe state and federal governments should provide incentives for purchasing green building products. Among builder respondents, 40 percent believed that incentives for both homeowners and builders would help promote green building.

This survey underscores a case for the viability of green building to protect the environment and save money. More findings from the study will be released throughout the year. While these will undoubtedly offer additional insight into how we can all help promote green building, the findings we have thus far clearly show us that this is something the public is looking for. It’s up to the companies and organizations involved in green building to help educate the public further on why this is such an important endeavor and why it can be affordable to all.

Editor’s note: In a earlier post in this series, Shon Anderson, VP of Energy Solutions at Schneider Electric points out that 70-75% of the total life-cycle cost of a building is in operation and maintenance and only 20-25% is tied up in the purchase price. Why then do we allow the high initial cost to be such a barrier? These costs should be amortized of the home’s life cycle. This would be a great opportunity, not only for government subsidies, but for the financial industry to step forward and provide mechanisms to make this happen.

Disadvantages of Building Green

Unfortunately, it seems that everything that is beneficial to people tends to carry a higher price tag with it. For example, the checkout receipt from a simple trip to the grocery store seems to double if the items that were purchased include fresh fruits, fresh vegetables and fish; instead of chips, cookies and canned foods. Just when a lot of people are seriously thinking about trying to help preserve the environment by building an eco friendly home, a few disadvantages to this type of construction are slowly beginning to rise to the surface. Of course, the primary concern is the tremendous initial cost that is usually associated with the whole “building green” process. Therefore, it is a wise thing to spend a little time and effort thoroughly sorting out and searching through all of the variables that may be connected to this fairly new style of constructing a home.

The most important stumbling block in this endeavor might just be the availability, or rather the lack of, adequate funding. This is something that will have to be quickly dealt with. Obviously, since this construction method is a fairly new concept to many people, the conditions and restrictions of such building loans might make it very difficult for the average homeowner to even be able to obtain a mortgage. Secondly, any potential green house builder also has to remember that since “building green” is a relatively newly introduced technique, the demand for these types of building materials has been very low up to this point in time.

Consequently, the possibility always exists that it may be more than a little difficult to obtain them from any of the material supply sources that are located in their particular area. As most people can attest to, the lack of competition automatically increases the prices of most items. Add to this fact, if a person has to order these things from a distant supplier, shipping and handling charges will also have to be included in the final price. Therefore, at the end of the day, the bottom line figure that will have to be mortgaged may be a whole lot more than some of the lending institutions will be ready to agree to. Locating qualified building contractors can become another exhausting undertaking.

Therefore, as you can see, there are a number of variables that just might have an adverse effect on the entire building process. Delving into any brand new idea or concept requires a whole bunch of planning, consideration and preparation. Try to envision how much more of all of these things will be absolutely necessary when dealing with a project of this magnitude.

Learning More About ICF Construction

By now, many people of heard of and are intrigued by green building techniques. Vertical ICF construction is one green building method that has seen resurgence thanks to its energy efficiency and environmentally friendly construction and installation process. Traditionally used in commercial building construction, ICF construction is as popular as ever in providing energy-maximizing savings and structural integrity to residential consumers. ICF, or Insulated Concrete Forms, are a type of wall that is generally made from cement-bonded wood fiber (usually made from recycled wood and cement) and polystyrene.

The strength of a building constructed with ICF technology will be unmatched in terms of strength, energy efficiency, noise reduction and comfort when compared to a structure built with typical wood frame construction. Termites and other pests and insects will not be attracted to insulated concrete forms, therefore eliminated the risk of having structural integrity compromised. ICF walls are mold, mildew and allergen resistant as well, so you can rest assured that your home would be a comfortable environment for you and your family.

Vertical ICF walls are ultra efficient when it comes to energy savings. Concrete and foam is the best insulator available for your home. You can save as much as 50% to 80% on your heating and cooling bills when comparing to energy costs of a traditional wood frame house. The high insulation value also makes it an ideal sound barrier, keeping exterior noises out of your home and interior sounds from escaping, allowing for better security and privacy.

Insulated concrete forms can withstand the highest winds that you would encounter with severe weather including hurricanes and tornados. Winds of up to 200mph are no match for ICF construction, and neither is fire. Insulated concrete forms are able to resist fire for up to 3.5 hours. Furthermore, ICF walls will resist mold and will not rot due to excess moisture, so your maintenance and general upkeep will be virtually non-existent.

Installation of insulated concrete forms is relatively easy and can be done quickly with an experienced green building contractor. Many ICF walls are made with recycled and environmentally friendly materials, non-toxic and not manufactured with any harmful chemicals such as formaldehyde. Installation is easy and even the waste products are kept to a minimum. Cleanup will be quick and easy, and the leftover waste products from the construction can be recycled.

It is easy to see why Vertical ICF construction techniques are gaining popularity, especially within residential buildings. The energy efficient, reinforced concrete walls have an unmatched fire tolerance, a high resistance to termites and pests, resistance to mold and mildew, and will result in the maximum amount of energy savings possible. The structural integrity of a home or building constructed with Vertical ICF walls will be much more enhanced to those constructed with traditional wood frames.

Green Building – Sustainable, Energy Efficient, Quality Construction Under Threat

In the midst of our recent economic crisis, the US federal government’s interventionist policies have again redeployed finite resources in contravention to market forces. Consumers and many custom builders have been pushing for better quality, sustainable, energy efficient construction. Unfortunately these market forces have been overcome by government intervention. The government has incentives for first time homebuyers who typically purchase cheaper starter homes. As a result almost all new construction is being undertaken by large tract builders who specialize in cheap housing. This end of the market is very price sensitive leading these builders to continued with larger designs that sacrifice quality for size.

Contrary to the belief of the US Congress, capital cannot be created by printing money or authorizing programs intended to create jobs. In a free market capital is deployed efficiently to areas with the best returns. When the government intervenes, it may skew the use of resources to less efficient enterprises. History provides us with numerous examples, but we do not have to look far back to see one of the best.

The deep recession we are experiencing resulted in large part from government interference in the housing market. The American dream has become the American nightmare. Successive governments, both Democrat and Republican, since the Great Depression have done everything they can to encourage privately owned housing. Government bureaucracies like the Federal Housing Administration and government sponsored, now government owned, entities like Fannie Mae and Freddie Mac artificially created a market for low interest loans to high risk customers. In a perfect storm, the Federal Reserve artificially depressed interest rates for a short-term economic boost.

Without artificially low rates and low credit standards, it is unlikely that the production of homes would have risen from 1.6M in 2001 to almost 2.1M by 2005. Post deflation the housing starts fell to 554,000 in 2009. At the beginning of the expansion, the Federal Funds Rate in January 2001 stood at 6%. When housing peaked the rate had been lowered to 1%. Not only did the volume of construction increase during that time, but the size of homes increase dramatically as did the price. Consumers were encouraged by lenders to purchase the largest home they could afford to take advantage of a once in a lifetime opportunity. Capital that might otherwise have been used in other areas of the economy was deployed in housing at artificially low rates. The result was catastrophic.

The same government is again intervening through first-time homebuyer tax credits. Coupled with low interest FHA loans having 3% down payments, they are creating some of the previously existing conditions. In addition to risking another bubble, the tax credits funded by all taxpaying Americans are being funneled to large corporate builders that specialize in low-end housing. This is evidenced by the fall in the median sales price in 2009 to $209,000 from a high of $262,000 in 2007.

Some of the larger builders have developed smaller plans, but they have mostly done so to meet the lower price points that the government influenced market demanded. They are not increasing the quality, sustainability or energy efficiency of their new homes. Though not all large home construction has stopped, only the truly wealthy, who tend to build better constructed homes, are still building. Homes of this quality usually include energy efficient systems and last much longer; both qualities of sustainable construction. Much has been written about “McMansion” homes, but generally homes in this market are not included. That is discussion for another day.

While tract home builders dominate the starter home segment, custom builders control the large home market. The real battle will be for the “move up market”. This market will determine the character of American housing for the foreseeable future. Move up consumers will chose between low quality, lower-cost homes built by large corporate builders and high quality, higher-cost homes built by small custom builders. Given the same available dollar for construction, the tradeoff is size for quality.

Assuming market forces determine lending limits, the average price of homes in the move up segment will likely remain much lower than previously experienced. At the peak the move up segment ranged easily into the $1M plus range. Those who grew accustom to the quality of higher priced homes will not likely abandon their affinity for hardwood floors, commercial-grade appliances, custom cabinets and granite tops. To match those features with a lower total budget, consumers will need to build smaller, high quality homes. The skill set to build these homes lies with the custom builder.

If Americans are truly interested reducing dependence on foreign energy and increasing sustainability in the housing market, we will need to decide to build smaller homes to offset the higher cost of quality construction. While it is possible that tract builders may chose to build smaller, their main advantage currently is delivering large size for a low price. Their organizations are not set up to deal with the custom aspects that would make their housing sustainable or more energy efficient. Through builder association programs custom builders have become much more educated in energy efficient, sustainable building to go along with their inherent quality.

The question now is whether the government will continue to incent consumers to continue a behavior pattern contrary to free market forces. If all new construction continues in the low end of the market, it will drive many of the remaining custom builders from the market. Already the number of builders belonging to professional organizations like the National Association of Home Builders has been drastically reduced. Most small custom builders are surviving only through remodel work, but if the market continues much longer many will likely move to other work. Rebuilding the knowledge base and expertise may take years and impact the overall quality negatively for year to come.
