The Hobbit House

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

It has long been known that without making your home air tight, there is no way for your insulation to perform at it true r value. For example if your walls are built with 2 X 6 studs and insulated with R-21 insulation batts, without the house being airtight, the insulation performs at a reduced R value, something around a R-17. This is caused by gaps between the studs and the insulation which allow air to leak by. The problem in the past with making a home air tight was that the process would also trap moisture in the walls, which would lead to dry rot. Back in the 80′s and early 90′s air tightness was tried by installing 6 mil. plastic on the studs and drywalling over it. With plywood or OSB on the exterior of the wall, this left no place for the water to escape. I remember walking into houses before the drywall was installed and watching the water run down the sheets of plastic. This method of air sealing was quickly dropped and no real alternative was offered. Some minor air sealing of the bottom wall plate to the floor with caulk and foaming around doors and windows is about as far as we’ve gotten with the codes.

Just this year Washington state has adopted a stricter insulation code. It is basically the old Energy Star standards. One part of the code is the requirement that all new home have a blower door test prior to final inspection. Blower door test measures the amount of air leaks a home has. New homes are required to have a blower door score of 7.5 or lower. What this means is that if the air pressure difference between the outdoors and the inside of your house is 50 pascals (50 pound per square inch) then the air in your house will completely exchange itself seven and one half times in an hour. This is still a drafty house but its a start.

By making homes airtight we obviously can cut down the cost of heating these homes. Done correctly we also can build the walls in a manor that will allow moisture to escape. This is the best way to build. In future articles I will talk more about the methods behind this type of construction

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.

Saving water is more often than not, the introductory phrase to environmental awareness. Ask anyone how they plan to save the environment and “Turn off the tap while brushing” is on their list of top three ways. However, saving water and using it efficiently is one of the most basic ways in which we can ensure our homes are green. While most of us will conscientiously try and maintain water saving habits in the house and encourage others to do so, a lot of water wastage happens in other, not so obvious ways. Therefore, while remodeling homes we often ask homeowners to look beyond turning their taps off to replacing them altogether with water efficient taps.
A sure-shot way of looking for faucets that can help save water is to look for EPA’s ‘Watersense’ label, a certification given to bathroom fixtures and accessories that use minimum water, no more than 1.6 gallons per minute, as per federal regulations. The Watersense label, a program by EPA, is an independent third party certification given to products that clear the strict federal requirements.
Water efficient bathroom fixtures are not just limited to faucet, they also extend to showerheads that provide the comfort, and ‘feel’ of a regular shower head while using only a fraction of the water. In fact, there is a range of products that have the Watersense label and can greatly limit your water usage and wastage. These products cost a little more than the regular products, however, are worth it when you consider their quality and reliability as well as efficiency and lifetime value. Replacing your current fixtures with water efficient, or even better, Watersense fixtures is bound to bring in large savings in your annual water bill. To know exactly how much, you can use the savings calculator on the EPA’s Watersense website.

1. Shades, Awnings, Blinds, Curtains and even foliage around the windows can affect solar heat gain and can also be a cheap way to cool the house.
2. There are five parts of a window that affect its energy efficiency: Glazing technology; Frame; Operating Type i.e. how it opens and closes; Low-E coatings; Gas fills; Spacers. You need to check all these aspects of a window and ensure that they are the best suited for your climate.
3. Depending on the kind of problem you think you’re likely to have, focus on each of the six parts mentioned above. For instance:
a. If you live in predominantly warm and sunny climate, then you will need to focus on Glazing, Low-E coatings
b. If your weather is humid, then attention to spacers, frames and operating type will keep condensation and leakage problems in check
c. In cold climates, glazing, frame, spacers and gas fills need to be checked well before buying
4. Energy-efficient mortgages are a way of paying for energy efficient windows, which typically cost more than regular windows. This actually turns out to be quite cost effective, because the savings on energy and utility bills arising out of energy-efficient homes offsets the monthly mortgage payments. To get more details, visit the energy department in your state.
5. Important: Get your energy efficient windows installed by a professional. If not installed properly, they will be less efficient than even regular windows. . Make sure your installation expert has experience in installing windows and is familiar that particular manufacturer.
