1. Sum of major fuels. Weather-adjusted energy consumption for 1999 is not reported because 1999 CBECS does not estimate energy consumption for space heating, space cooling, and ventilation. Normals are based on calculations of data from 1971 through 2000. To aggregate Census division degree-days to Census regions, each division value is weighted by the 2000 population shares of divisions within each Census region.
3. Laboratory buildings are included in the "Other" category.
Q = Data withheld because the Relative Standard Error was greater than 50 percent or fewer than 20 buildings were sampled.
