 Additionally, buildings comprising 1,955 million square feet used propane; buildings comprising 382 million square feet 

used wood, coal or some other energy source; and no responding buildings in the sample used solar as a primary spaceheating energy source.

Q=Data withheld because the Relative Standard Error (RSE) was greater than 50 percent, or fewer than 20 buildings were 

sampled.

N=No responding cases in sample.
