Claim One:
1. A building energy system comprising: a building including a ventilation system communicating with heat exchangers for controlling the temperature of circulated air in the ventilation systems; a series of sensors providing first to data inputs of real-time measurements of the ventilation system providing parameters of the building energy system; an electronic computer communicating with the series of sensors and executing a program stored in a non-transient medium to: (a) receive first data inputs of real-time measured parameters of the energy systems; (b) receive second data inputs of current and predicted local meteorological information; (c) apply predicted local meteorological information and real-time measured parameters of the first and second inputs to a model of the energy system to produce predicted parameters of the energy system; (d) apply the predicted and measured parameters to alert rules to generate alerts related to future avoidable energy cost increases; and (e) output the alerts providing information indicating a future avoidable cost increase and a prediction time associated with a predicted time of the future avoidable energy cost increase wherein the electronic computer further executes the stored program to output to a user the predicted measured parameters; wherein the electronic computer further executes the program to apply predicted local meteorological information to a second model of the energy system to produce predicted electrical and steam cogeneration wherein the output from the second model provides an input to the model.
