The "net-zero" home in Durham that we have been working on is not only trying to reduce their expenditures later by utilizing energy saving construction but they are also saving money during the framing process by using advanced framing techniques. Advanced framing techniques (also called Optimum Value Engineering) start with a well thought out framing design that considers common lumber and sheet sizes. This reduces waste, minimizes cutting and consequently material and labor costs. Advanced framing also leaves more room for insulation and eliminates cold spots, thus making the house less expensive to both heat and cool. This home has given us an opportunity to try out a new product, Home Slicker. You may have seen a home under construction and noticed that the home was being wrapped with black paper or Tyvek. This is done as an added barrier to keep moisture out. We'd originally planned on creating channels for rain to drain behind the siding with wood strips until we found the Home Slicker product. In the picture below you can see the channels allowing for drainage built right in!
After numerous discussions and reviews with the Town of Carrboro regarding lot reconfigurations, storm water drainage issues. etc. etc., we are finally on our way to building two new energy efficient affordable homes in Carrboro.
There are many features of these homes we are building in conjunction with the Community Home Trust that contribute to their being a great example of affordable Green building. One that will no longer be evident after completion of the home is our employment of advanced framing techniques. Advanced framing (also called Optimum Value Engineering) results in lower material and labor costs and improved energy performance for the building, due to less conductive temperature transfer through the framing components. Consequently, effective use of advanced framing techniques starts with a well thought out framing design that considers common lumber and sheet sizes. This reduces waste, minimizes cutting and consequently your material and labor costs. Architect David Ripperton's conscientious design work was crucial in this effort to build with both energy efficiency and affordability in mind.
