Like many industries, innovations in green home building have become mired in speculation and myths. The heavy use, and often misuse, of  “green” messages across many industries has fostered a cynicism for some. While others are holding on to the early price tags or associations with the word.

However, like many industries, the building industry is always evolving. As we discover new information, technologies and products we have learned that green home building is not as much a type of building as it is the next evolution in building. Green and energy efficient homes are what have resulted from research and innovation, and with that understanding are gaining a much wider acceptance.

Here are a few of the top myths about green home building that we hope won’t be around much longer…

Green homes are no longer more expensive to build.
When energy efficient building products first came on the market they were leading edge, and tended to be more pricey that their traditional alternatives. We see this trend in every industry from electronics to clothing. However, as companies begin adopting sustainable, eco-friendly and energy efficient models in their design and practice the cost continues to come down. And most importantly, the cost of living and maintenance during the lifetime of the home is reduced with more durable construction and materials over traditionally built homes.

Remodeling a home is not always more “green” than building new.
Homes that were built 50 or 60 years ago were built with very different tools and specifications. For instance, some homes weren’t built with insulation at all and did not take into consideration environmental factors such as the home’s orientation on the lot to take advantage of natural sunlight and warmth. But as we learn more about how the environment around the home impacts everything from energy bills to the health of the homeowners, we are now building homes that are more efficient and comfortable when a remodel could not possibly meet these needs.

Green homes are not just for environmentalists.
Since we began building green homes in 2006 we have incorporated energy efficient and sustainable practices into projects for so many clients for so many different reasons. The top reason, however, comes down to increased durability, less maintenance problems and lowered utility bills. While there are environmental benefits to all of these factors, at the end of the day these homes are also better investments for our clients because of these same reasons.

As time passes and people begin to understand the benefits of using green practices when building their new home we suspect that there will also be a better understanding that green building is more about innovation than a movement.

Recently we came across a great post by St. Louis Realtor Karen Goodman on radon risks for Missouri homes, a hot topic for many home builders and buyers in the St. Louis area. It caused quite a buzz among the Hibbs Homes staff.

To get some more insight on the matter we turned to our consulting partner, Matt Belcher of Verdatek Solutions. Matt, one of the country’s leading green home standards experts, recently joined our home building team and brings with him a wealth of knowledge not only about green building standards here and abroad, but also a very unique expertise with radon in Missouri homes.

A few years ago Matt received a grant from the Department of Health to attend a Radon educational symposium in Washington D.C. At the time, he was one of the first builders to begin roughing in a radon mitigation system during new home construction.

Matt said of the symposium, “It really drove home the nature of the importance of these systems in every home we have build. We are one of very few builders who do this or frankly understand Radon and its effects.”

Radon is naturally occurring, radioactive gas produced during the decay of deposits of uranium and radium in the soil and air. When radon enters the home it radioactively charges dust particles, which become carcinogenic and when inhaled can lodge in your lungs. In fact, radon is the second leading cause of lung cancer behind smoking, and the number one cause of lung cancer in non-smokers according to EPA estimates. And studies conducted by the agency show that even a small amount of radon can cause lung cancer.

As the map in Karen’s post points out, Missouri is located in a “median” risk radon zone. This means that while the risk is slightly elevated, concentrations are not as predominant as they are in areas to the North and west of us and mitigation is optional by code.

In terms of risk, Matt explained, “The maximum standard measurement level for Radon is 4 Picocuries/liter (pCi/L). However, that is a somewhat “arrived at” number. The average home has about 1.3 pCi/L indoors. The true effect of any Radiation is time vs. exposure. If you spend the bulk amount of your time in the lowest level of your home and are in an area with even lower levels you may be effected more than someone even in non-conforming areas but spend little time in the lower level.”

Now that many home buyers are aware of the risk a radon inspection is an increasingly common closing inspection, and if detected a mitigation system can be installed by a contractor prior to closing, which can be costly.

However in St Louis new home construction a more proactive approach is being taken with the knowledge that our area has a slightly elevated risk. In new homes a passive mitigation system is being installed in the form of a pip that runs under the lowest floor slab, and using the natural tendency for warm air to rise the vapor vents up through the roof. And even more progressively, Matt explains, “We always leave a length in the attic adequate to install a fan if our client would desire to make it an active system in the future.”

While radon detection and mitigation may only be optional in this area, a radon inspection and a proactive preclusion system is an important when building your home in St Louis to reduce your family’s health risk.

For more information about radon’s risks and effects we invite you to explore the EPA’s radon website, and, like most important homeowner issues, consult a trusted contractor or realtor.

Hibbs Homes Superintendent Dean Holtmeyer discussing plans with a clients building a new home..

When homeowners first think about building a home, their search for plans often begins on the internet.  It is an endless and sometimes valuable resource.  While the price for stock blueprints can be enticing, unless you do your homework you could be making a costly mistake.

There are several factors to consider when deciding whether to buy plans online or have them drawn by a local architect.  In the St. Louis area, where we build most of our homes, plans must be signed and sealed by a Missouri licensed architect. These licensed architects know local codes which can vary greatly from municipality to municipality. While online blueprints are typically designed to meet one general building code, and if you request they be updated for your specific area the cost usually goes up.

Many time stock plans can’t account for specific site details you’d like or related to your lot, such as a walkout basement.  Also, depending on local requirements, you may need additional engineering work which can be costly if making major changes. What seems like an easy tweak could affect the entire structure from the foundation to the roof.  It may be better to start fresh with a local architect.

When evaluating whether to buy plans online the best way to proceed is –

1.   Review the plans you are considering to make sure they meet your needs without having to make changes

2.  Contact your local government’s building department to see if they will allow stock blueprints

3.  Discuss any special code and/or engineering requirements your municipality

4.  Get a formal quote including costs for changes to plans and special code and/or engineering requirements

5.  Compare the stock plans with an apples-to-apples quote from a local architect

If you simply choose the plans that seem cheapest upfront, you could be making a mistake.  Doing your homework will help keep your dream of a new home on track and on budget.
