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 increasewherein 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.

Abstract
A system for managing energy use of buildings and the like uses predicted meteorological data, for example from weather forecasts, applied to models of the energy systems of the building to predict future energy use and costs. This predicted information is used to produce automatic alerts allowing future energy use to guide current changes to reduce energy.
