This is the last day this house will be open to the public. Come out today between 10am and 4 pm to see this amazing one of a kind house with the round front door. Whimsical and charming, this house hides the fact that it is on the cutting edge of Built Green and sustainability. I will be hosting the house all day along with Diane Gassman of Interior Dimensions. It’s a house everyone should see. From Rainer rd, turn right on Steadman, right on 103rd and left on Katie Ann. From Hwy 99 turn left on Waldrick, left on Steadman, left on 103rd and left on to Katie Ann
The February / March issue of South Sound magazine features a story of the Bouvier/Rogers home which we at Laupen Homes LLC. built last year. The article includes some wonderful photos of the home that really capture the fill of this unique house. Of course there is a great photo of the round, hand carved wood door along with others of both the interior and exterior of the house, however one photo in particular is especially impressive. It’s a photo taken of one of the master bath vanity’s and mirror. At first it looks to be just a good picture of the vanity until you look at whats in the mirror. Thats when you notice that the photographer was able to capture the walk in shower, second vanity, and the other mirror. It’s a wonderful photo and worth a look.
Along with a story that talks about the unique aspects and energy efficient features of this home, you’ll also find in the article, the phone numbers and web site addresses of many of the subs and supplies who’s work is featured. You can find the magazine starting tomorrow in news stands and grocery stores throughout the south sound.
Sometimes getting the U-Factor, SHGC and VT values right is not enough. Often, the installation of the window itself, i.e. the entire window assembly can have flaws. These flaws result in air leakage – one of the main obstacles in trying to achieve energy efficiency with the help of windows.
If your house is built on the Passivhaus principles; or you are looking at seriously reducing your HVAC requirements (and thus the bill) then air leakages through windows can punch a large through your plan. Some energy efficient windows specify the AL value (expressed in cubic feet of air passing through for every square foot of the window assembly) between 0-1. The lower the value, the lesser the leakage. The industry-accepted value is 0.30.
Another problem for insulation is condensation. If you live in cold areas, you’ve probably seem frost or dew on the edges of the windows. Looks quite ‘Christmassy’ but it only means that much more heating load. Condensation happens when inside warm air comes into contact with cold panes and glass, which essentially means your windows are not doing such a good job insulating.
With condensation and air leakage, there aren’t fixed ratings to go by. However, certain materials and window technologies work better. For example, if you’re opting for multiple pane windows, looks for stainless steel spacers, or thermally improved spacers made from silicon foam or butyl tape. These spacers might be more expensive, but they are better are insulating, sealing and thus preventing unwanted heat transfer, while at the same time allowing from seasonal expansions and contractions in panes. Similarly, opting for energy efficient windows with two or more panes or glazing reduces condensation even at indoor humidity levels of 45-60%. This is especially true of windows with argon/krypton glass filled windows.
No, we are not switching to promoting green software – we’re going to stick to good ole’ hardware and home building. For a long time, windows have been thought of just as basic necessities to a house, or as ornamental and status-symbols. However, windows are a big factor in terms of our electricity bills, keep us healthier, make our homes last longer, save energy and essentially, save the planet. However, they can do all this and more.
Eco-friendly windows are essentially energy efficient windows. The make, material, frame, size and positioning of windows has a great impact on interior lighting, indoor temperature, heating & cooling systems and indoor air quality. Energy efficient windows work at maintaining optimal levels of all these aspects and thus significantly reducing our bills and our carbon footprint. And with the new eco-friendly wave taking the construction industry by storm, energy star certified windows are easily available. Also, the certification system is such that it works well for different kinds of windows that are made for different home requirements and weather conditions.
Yet, it can still get quite confusing and most of us are not quite familiar with scientific window terminology. Essentially, when you buy energy efficient windows, you will come across a lot of numbers and ratings. There are five things you need to look at:
1. U-Factor (Level of heat transfer)
2. Solar Heat Gain Co-efficient (Heat capturing capacity)
3. Visible Transmittance (Light Transfer)
4. Air Leakage and
5. Condensation Resistance
And that’s why we have a series of how to understand and buy energy efficient windows – without wishing you’d done more math in high school.
The Eco Builders Guild \ South Sound Chapter has announced it will host the South Sound Green Tour on April 17th and 18th, 2010
The theme of the event will be Innovation – Education – Inspiration
It will be a community event to celebrate green innovations through education in sustainable building and inspired living.
This year’s tour will showcase the greenest homes and buildings in our area that incorporate significant use of solar or other renewable energies, new and reclaimed materials, low energy consumption and water conservation technologies, and sustainable design techniques.
Educational sessions will be held at various locations and feature real life topics on how to build and live greener. See our website for more details – www.SouthSoundGreenTour.com ( The site should be up and running by January 1, 2010
South Sound Green Tour is looking for participants and sponsors. If you are interested in either contact me at email@example.com. After January we you will be able to contact us directly at SouthSoundGreenTour.com
