Abstract:
1. A method for assessing, forecasting and simulating energy consumption of buildings using energy efficiency coefficients, comprising: correlating, using a processor, energy consumption data of a building and temperature data outside the building collected over a period of time; segmenting the correlated energy consumption data and temperature data into a plurality of segments including at least a heating consumption segment, a cooling segment, and temperature-insensitive segment; determining an energy efficiency coefficient for heating from the heating consumption segment; determining an energy efficiency coefficient for cooling from the cooling consumption segment; determining an energy efficiency coefficient for other energy consuming activities from the temperature insensitive segment; scaling the energy efficiency coefficients for heating, cooling and other energy consuming activity by building characteristics, using the energy efficiency coefficient for heating, the energy efficiency coefficient for cooling and the energy efficiency coefficient for other energy consuming activities to assess energy efficiency among one or more buildings, forecast future consumption of energy in the building based on forecasted temperature, and simulate impact of hypothetical temperature and hypothetical energy efficiency on energy consumption in the building.
