Patent ID: 8359215

Claim:
A system, comprising: a memory that stores: historical weather data associated with a site, the historical weather data comprising a number of degree-days at the site for each of a plurality of previous time periods; and historical usage data associated with the site, the historical usage data comprising an amount of utility usage at the site for each of the plurality of previous time periods; and a processor that: determines a normalization formula based on the relationship between the number of degree days for each of the plurality of previous time periods and the amount of utility usage at the site for each of the plurality of previous time periods; determines, based on the normalization formula, a balance point of the site, the balance point representing an amount of utility usage at the site during a time period having zero degree-days; normalizes an actual amount of utility usage at the site during a particular time period based at least in part on the balance point and a number of degree-days at the site for the particular time period to generate a normalized amount of utility usage at the site during the particular time period; and generates a graphical user interface that displays the balance point and the normalized amount of utility usage.
