Synergy Building Company has built quite a few sealed crawlspaces. Generally, whenever we are building a new home, or putting on a new addition, we strongly recommend that the crawlspace be sealed and semi-conditioned space. This is also the case with sealing attic spaces. The advantage of keeping HVAC equipment and ducts in a semi-conditioned space makes sense for a lot of reasons. Now, we are finding more interest in sealing existing crawlspaces and attics, as part of an attempt to establish more energy efficient homes. Advanced Energy, in Raleigh, is a great resource for learning about the comparative advantages of various energy efficient techniques in residential construction. Here is an interesting article on sealing attics for those who are considering this upgrade to their home. Here is a picture of what sprayfoam insulation looks like in a recent Synergy project.
On April 22, 2010, just in time for Earth Day, the AGC (Associated General Contractors of America) released a report called “Building a Green Future." It’s a very comprehensive document that provides a blue print for increasing demand, and funding for environmentally conscious construction techniques, and how following these plans would make a big impact on our collective carbon footprint going forward . Here are some interesting comments from the report:
In the U.S. we use nearly 40 percent of our nation’s energy to power our buildings —this includes lighting, heating and cooling, appliances and electronics. Accordingly, our buildings accounted for 35 percent of the nation’s total manmade greenhouse gas (GHG) emissions in 2008.Residential and nonresidential buildings also use approximately 13 percent of all potable water and 40 percent of the non-food/fuel raw materials use.
By one estimate, the landscape of our buildings will be altered 75 percent by the year 2035 through the typical pace of change: from new development, complete demolition and redevelopment to the major renovation of existing buildings.The report provides some interesting definitions of “Green Building", for both commercial and residential projects, and provides a road map of numerous steps, that if used in our construction projects going forward, could make a substantial improvement in our environment. You can take a look at the entire report here.
Recently you may have read in the paper or heard about the "new" law aimed at protecting children from the health hazards associated with lead based paint. The law requires training and sets work practice standards for contractors working in homes that were built prior to 1978. While the law has received a lot of press recently, as it has become effective as of the end of April 2010, it was proposed in the spring of 2008, and has generated lots of discussions. If you're interested in a brief synopsis from the EPA detailing how this regulation effects builders and subcontractors take a look at this helpful link. Synergy Building Company is currently in the process of becoming an EPA certified firm to handle renovations effected by these regulations. We support the intentions of this legislation, and believe that all who are potentially impacted by this type of renovation work, including those doing the work will ultimately benefit.
