(*)=Value rounds to zero in the units displayed.
Q=Data withheld because fewer than 20 buildings were sampled for any cell, or because the Relative Standard Error (RSE) was greater than 50 percent for a cell in the "Total" column.
N=No responding cases in sample that used district heat.
Note: Due to rounding, data may not sum to totals.
