Abstract:
1. An improved computer implemented method of managing energy usage of a building, where said method includes steps of collecting and analyzing building data, identifying building energy reduction opportunities, characterizing said building, applying optimization process to management of said building, and monitoring building energy usage and reporting results, thereby enabling on-going building energy usage optimization, where in the step of characterizing said building said improvement comprises substeps of: (a) using a processor for calculating (b) determining from results of sub-step a(i) a minimum value, and further selecting a range of external temperatures corresponding to said minimum value, where said selected range represents lagged average external temperature; c) determining from results of substep a(ii) a minimum value, and further selecting a range of external temperatures corresponding to said minimum value, where said selected range represents lagged solar gain; (d) determining a solar strength value for said building; (e) using said building's lagged average external temperature and said solar gain and said solar strength from steps (a) through (d) to determine said building's energy use requirements using an equation wherein γ represents thermal energy used by said building of interest and averaged over a predetermined time, x x x β β β β ε is estimated variation.
