Examination of climatic conditions in the twelve Midwestern states of Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota Missouri, Nebraska, North Dakota, Ohio, South Dakota, and Wisconsin reveals that this region receives from 50% to 70% of the possible annual total hours of sunshine.

Degree day heating requirements range from 4,000DD to over 10,000DD per year. In the northern tier of states, some areas require heat at some time in each month.

The FCHART Method for Solar Heating Design, developed at the Solar Energy Laboratory at the University of Wisconsin, is a method for making a computer study of solar capability for selected cities in the United States.

Thermal analysis of a selected typical housing unit was made by the FCHART method for thirty- two Midwestern cities. Percentage of heat provided by the sun varies from 87.8% in Dodge City, Kansas, to 70.5% in East Lansing, Michigan.
