Ward Lutz Case Study
Updated 02/13/12 - This is one of the first homes in the United States and the first Ohio project to meet the Thousand Home Challenge. It is a net energy producer. Based in Urbana, Ohio, this 60 year-old home met the threshold allowance a year after work was completed. Since then the addition of a PV array and ductless heat pump have moved Ward Lutz’s home even closer to his goal of minimizing his carbon footprint.

Bill Turner Case Study
Updated 02/28/12 - Located in the mountains of Utah, this staged project has made impressive reductions to date but still needs to cut energy use by half to meet the Thousand Home Challenge. Features include a major basement remediation to create livable space, significant reduction in air leakage, integrating insulation of a cathedral ceiling as part of re-roofing as well as greatly improved comfort and elimination of an infestation of critters. While this log cabin reduction project has some elements unique to its 8,000 heating degree days location, there are practical lessons appropriate to house foundations and roofs in many parts of the country.
