1. A method of managing energy usage in a building system, comprising:

  • managing energy usage history data of a plurality of energy consumption devices in the building system, the energy usage history data comprising one or more energy usage peaks previously reached by the building system;

    monitoring current energy usage of the plurality of energy consumption devices in the building system;

    monitoring a plurality of global variables comprising a building temperature, a building humidity, a building CO2 level, a weather forecast and a real-time energy price;

    forecasting whether or not a new energy usage peak is approaching based on the current energy usage and the energy usage history data; and

    automatically initiating a real-time control of each energy consumption device based on the plurality of global variables in response to a forecast that a new energy usage peak is approaching.
