Green Home Revisited – The Shoe Storage Area

March 19, 2012

Shortly after the home was finished, we began holding open houses to promote the completion of the first LEED certified home in Wichita and “green” building. During one open house, the local Fox TV station made an impromptu appearance to prepare a segment for their 9 o’clock news program. They were most intrigued by and show-cased the shoe-storage area because it is not immediately obvious how such a space would contribute to sustainability.

But in fact, in the LEED rating system, this home did earn one (1) point for having a built-in shoe removal and storage space. Here’s the reasoning: Since Americans spend an average of 90% of their time indoors, LEED rewards homes that address issues related to “Indoor Environmental Quality”. According to the United States Green Building Council (USGBC), a majority of the dirt in homes is tracked in by the occupants on their shoes. This debris can contain lead, asbestos, pesticides and other hazardous material. Shoes will also track in moisture that could lead to mold growth on the carpet. A built-in bench and shoe storage area, right at the main entry into the home, will encourage the occupants to remove their shoes. Less dirt and contaminants equal better indoor air quality, less energy to run the vacuum and fewer  chemicals to clean the floor.

We asked the homeowner if he was using the area. He replied that he was and that “it’s a very nice thing to be able to come in, sit right down and take your shoes off”. While we have no quantifiable measurements on the indoor air quality, nor on the vacuum usage, we can point to a homeowner who likes the convenience and is happy with this feature.

Green Home Revisited – In The News

February 10, 2012

The only LEED certified home in Wichita.

“What makes this home special?’ is the title of a feature article, written by Ron Sylvester, that appeared in the Wichita Eagle newspaper on November 15, 2011. The answer is, it’s the only one LEED certified in Wichita. Read Ron’s article and watch his video at www.kansas.com.

Green Home Revisited – Bamboo Flooring

November 7, 2011

This is the first of several blogs we’ll be doing to check in on the ‘green’ home – to see what features have worked well, and maybe a few  that could have been re-thought.

For this first blog, we  went back and looked at how the bamboo floor was holding up.

Bamboo is one of the darlings of the sustainable  construction world.  It is very much  like wood but actually it is a grass; a very fast growing grass.  It is this rapid growth that defines it as  sustainable.  It can be harvested in 5-7  years; versus 60-70 years for most hardwoods. It is moisture resistant and  insect resistant. In general, it is harder than oak, although it is available  in a wide range of hardness’s. As for installation, it can be nailed, glued, or  floated just like a conventional wood floor.

During the design phase of the home, we had planned for cork  flooring, another sustainable option. However, the homeowner decided to use Bamboo simply for it’s aesthetics.  Premium  Green Bamboo, Hand Scraped, Vintage Collection, Jacobean flooring was chosen and it looked fabulous when it was first installed.

It appears that not all bamboo flooring is equal.  A Google search will reveal a wide range of experiences with bamboo flooring – from very satisfied to very unsatisfied. The 2 major complaints seem to be softness (showing scratches) and color fading. Our LEED home, however, has had neither of these issues. As you can see from the photos, after 18 months of use, the floor still looks fantastic. The owner pointed out one dent where he had dropped an electric drill.  Otherwise it looks as good as the day it was installed. It has even held up to high heels and dog traffic.

So far,  for this home and this home-owner, bamboo flooring has proved to be a great sustainable choice.

Parade of Homes

May 10, 2010

For three weekends in April, Bauer and Son Construction held an open house for the Spring Parade of Homes, sponsored by the Wichita Area Builders Association. On Wednesday, April 12th, after the first weekend, our house was judged to be one of eight in the parade to win an award in the Most Unique Features category. Each winner in this category won for a different “Most Unique Feature”, our feature was being the 1st LEED Home in Wichita.  

2010 Spring Parade of Homes, Judges Award for Unique Feature

We want to thank the 177 people who visited our house during the Parade. We hope everyone who came to our open houses in March and to our Parade of Home open houses in April learned a little more about green homes.

Certifications & Acknowledgments

April 16, 2010

Soon after the third-party performance testing was performed, all the required forms were submitted to the various agencies to review and approve our applications for certifications.  

  

Sponsored by the US Department of Energy, Builder’s Challenge recognizes exceptional attention to quality and energy performance. The program uses the EnergySmart Home scale to rate efficiency. To meet the challenge, a home must achieve a rating of 70 or lower, representing an improvement of 30% over a typical home. This home met the challenge on March 1st, 2010 with a rating of 55.  

  

The NAHB Green Building Program was initiated in 2005 by the National Association of Home Builders. The NAHB Green Building program is similar to LEED, but only applicable to residential construction. Green Building Program houses are awarded points within specific categories and can receive a rating of Bronze, Silver, Gold or Emerald. On March 24, 2010 this home was awarded a Gold rating from NAHB.  

  

The LEED for Homes® rating system is the nationally accepted benchmark for the design, construction and operation of high performance green buildings. LEED projects are awarded points within specific categories and can receive a rating of Certified, Silver, Gold or Platinum. We are proud to report that on April 6th, 2010 this home was awarded Gold certification.  It is the first home to achieve LEED certification in Wichita, Kansas.   

  

ENERGY STAR® was developed in 1992 by the U.S. Department of Energy (DOE) and the U.S. Environmental Protection Agency (EPA). Its mission is to promote clean and efficient energy technologies, enabling consumers to save money while protecting the environment. This home received the ENERGY STAR on April 8th, 2010.On Friday, April 9th, Teresa Burk, from the Wichita Committee of the USGBC Central Plains Chapter presented Adam Bauer with the LEED for Homes – Gold certificate.

Furniture

April 15, 2010

Now that the testing and the final inspection are complete, furniture can be move in. Since the house will be used for promotion of “green building” by holding open houses and entering it in the Parade of Homes, it was decided that some furniture would help it “show” better.

Third-party Performance Testing

April 15, 2010

While energy modeling was performed as part of the design process for this house, verification of the actual tightness of the home is required as part of the perfornance testing for LEED® for Homes Energy and Atmosphere, AE category. This test is performed by utilizing a diagnostic tool called a blower door which is designed to measure the airtightness of buildings and to help locate air leakage sites. A blower door consists of a calibrated fan for measuring an airflow rate, and a pressure-sensing device to measure the air pressure created by the fan flow. The combination of pressure and fan-flow measurements are used to determine the building airtightness.

The blower door being installed in the Maseter Bedroom door to the deck. The fan is on the floor, behind the technican.

The technican is recording readings from the pressure-sensing device connected to the blower door.

The data from this test will be used to determine the final HERS rating the house will receive.

Since we are not now going to qualify for Indoor airPLUS, we lost 13 points in the Indoor Environmental Quality category. In order to still be certified at the Gold level and achieve as many points as possible in this category, we now need to take the alternative Pathway 2 which is the Perscripitive Approach. This pathway includes 9 sub-categories that can be used to achieve points. Compliance with two of the sub-categories, EQ 5 Local Exhaust and EQ 6 Distrubution Systems will allow us to regain 3 points.

This test pictured below is for EQ5 and is performed for all the exhaust fans in the house. An exhaust fan flow meter measures the cubic feet/minute (cfm) at that particular fan and that data is compared to the fan manufacturer’s rating.

The test pictured below is for EQ6 and is performed for all the supply air duct openings in the house. This device, a balometer capture hood, measures the cubic feet/minute (cfm) at a particular opeining and that data is compared to the original design criteria.
