2014 January Home energy index (BTU/DD SF) 2.67

The HEI calculated each month tells us how well we are doing with respect to
conserving energy. The goal is to make the HEI go down each month. This means
that no matter how cold or hot it is we can still measure our progress. We can
also compare this value (normalized for home size as well as temperature) to other
homes. So, my neighbor's HEI value should be relatively close to the HEI value for
my home. Of course, a little friendly competition might be helpful to inspire us both
to conserve more each month.
