4033 N 22nd St. Arlington, Va. 22207 For Sale!
Site Selection:
                As the old adage goes there are three important rules for selling a house: location; location; location. Well we know there is a lot more that goes into building a good quality home. However, location is a very important part of our building process.
                As Green/ Energy Efficient builders we take site selection into our building process. We believe that smart infill growth is sustainable and efficient. Most green building programs, LEED, Earthcraft, NGBS award points for proximity to community amenities such as stores, restaurants, churches, etc. If you are lucky enough to live and work in Arlington, like I am, than you know how convenient and special it is.
                Our newest house located at 4033 N 22nd St. Arlington, Va. 22207 has a walk score of 69 and a bike score of 80. Because of the great location the future owners will have the ability to walk, bike or take public transit to any location in the Metro DC area. 
                As part of our LEED rating we will gain points by showing how this infill building site will rely upon existing infra-structure rather than having to build new facilities to accommodate a new home. This site already has gas, electric, sewer and water to it. So it is a matter of merely connecting to these utilities rather than having to cut down trees to install a separate septic system for this one house, for example.
                Working in and near the communities in which we live saves us valuable resources in time and fuel expenses while helping to reduce total greenhouse gas emissions associated with these transportation costs. 28% of all energy use in the United States is consumed by transportation. 
Almost half of all energy consumption is consumed by our buildings, which is why we are working to improve the total energy efficiency of where we live. But that is another topic for another blog. Stay tuned!

Geo-thermal and the Whole House System



                Arlington Designer Homes has started drilling for our next new custom and new home For Sale: 4033 N 22nd St. Arlington, Va. 22207. We are drilling for our Geo-thermal wells. It is a very exciting time and process. We have been through county review, we have our plans and permits approved and we are ready to go.
                Geo-thermal drilling is a loud and sometimes messy process. We will be drilling 3 wells total for the two homes. The first well we are digging will be 290’ with the 2nd and 3rd being 220’ deep each. The depth of the wells is determined by the size and construction of the house. For more information on Geo-thermal systems see our blog from 11/5/2010.

                Let me take you back a few months. The first thing that you need to do when you are considering Geo-thermal well installation is to calculate the load of the house. The ‘load calculations’ are based upon the specifications of the house. In our case because we will build a tight house, 2x6” walls with exterior ‘out-sulation’, high performance windows and doors and advanced framing. Using these techniques we were able to keep the total heating and cooling load for the house down.
                What this means is that because we are designing a more energy efficient, tight house to begin with we start saving money and creating a more comfortable home immediately. Before we have even put shovel to dirt we are already reducing overall construction costs and ultimately overall operating costs for the home. Proper prior planning is a key component of the LEED certification process, more on that in our next Blog.
                Specifying and modeling the house is a key component of what Arlington Designer Homes does. We plan for the heat load based upon the super energy efficient houses we build, then we monitor how the plans and decisions we made sometimes years ago affect the energy efficiency, performance and overall comfort of the home. With the new data we can tweak our systems, update our modeling and continue to improve our systems.
                We look at the whole house, and the construction of the whole house as a systematic process. A affects B which in turn affects C. The decisions we made a year before we decided to go Geo-thermal necessarily affects the HVAC system and beyond. It changes the whole level of efficiency performance and comfort for the whole house. Having made these decisions we are excited to finally be putting them into practice.
