  Just by way of introduction, I have been the Home Improvement Editor of VICTORIAN HOMES MAGAZINE for over 23 years. I thought my passive solar house project & website might be of interest to you and your website.

  A little over a year ago I designed and built a new traditional style 4000 sq. ft. affordable passive solar home for $125.00 a sq. ft., assembling technologies and incorporating design features that enable it to heat for $2.50 a day ($900-1200 a year in the cold Upstate, NY region with crude around $100 a barrel). The website is: http://www.SolarHouseProject.com. The website explains how the home was built and how it functions. Dollar for dollar this traditional style passive solar home far exceeds the cost-to-benefit ratio of any “green” or “zero energy” home today. Heated by the sun, it cost about the same as a comparable size new ENERGY STAR qualified home but uses less than 70% of the energy of that comparable new home. 80% is possible if this home was built in a comparably cold climate but was not in my Snow Belt area and had regular height ceilings.

  When I owned my previous home, I was unaware that trying to save energy in an existing home was just playing in the margins of energy conservation. It became clear to me that existing 20th century homes are obsolete energy sieves that will take Herculean measures to bring up to speed in the 21st century. This passive solar home can become the model for 21 century home building and rekindle a housing boom in our collapsed building market into the foreseeable future.

  An article on the Kosmer Solar House Project is in the current Better Homes and Gardens Special Interest Publication NEW HOME annual and another article on it is in the quarterly summer issue of NYS regional magazine Kaatskill Life.

  Below is an hourly chart I made of the outside/inside temperature of the home on 1/3/08 that shows that on a sunny cold single digit day the house was heated only by the sun for 10 hours. It was the acid test for the house and is amazing.
