A controller for controlling energy consumption in a home includes a constraints engine to define variables for multiple appliances in the home corresponding to various home modes and persona of an occupant of the home. A modeling engine models multiple paths of energy utilization of the multiple appliances to place the home into a desired state from a current context. An optimal scheduler receives the multiple paths of energy utilization and generates a schedule as a function of the multiple paths and a selected persona to place the home in a desired state.

A solar energy thermostatic controller using a solid-state microcomputer that manages air mover(s) to supply heated air for building space heating. Methods includes microcomputer software for communicating with temperature sensors located at the solar heating source, the supply vent source and the building room/interior. The present invention thermostatic control device features a data logger to record temperatures and humidity history, and elapsed time usage history of solar heated air available from attics and crawl spaces; or solar collectors mounted in or on walls, rooftops, or exterior locations. The thermostatic control device manages use of limited solar heated air for building environmental control. Program controlled temperature set points manage an HVAC blower to gather solar heated air during the daily sunlight solar excursion and to control shutdown of the supply system when solar heated air temperature falls below present room/interior temperature. Methods include permanent memory storage of historical data.

Disclosed are methods and functional elements for enhanced thermal management of predominantly enclosed spaces. In particular, the invention enables the construction of buildings with reduced power requirements for heating and/or air-conditioning systems since under certain conditions less energy for heating or cooling is required to maintain, within certain boundaries, desirable temperatures inside such buildings, habitats, or other enclosed spaces.

In some instances the invention is in part based on dynamically changing functional elements with variable properties, or effective properties, in terms of their electromagnetic radiative behavior and/or their thermal energy storage properties, or the spatial distribution of the stored thermal energy, which permits the application of methods and algorithms to control the overall thermal behavior of the entire structure in such a way that desired levels of inside temperature can be reached with reduced consumption of external energy (typically electricity, gas, oil, or coal).

In some instances no conventional heating of cooling is required at all, whereas in other instances the expenditure of external energy for conventional heating or cooling is reduced. In some instances the invention enables the reduction of the time to reach desired temperatures inside such buildings, habitats, or other predominantly enclosed spaces.

In some instances the obtained sensor data may be used to detect the occurrence or imminently predicted occurrence of a catastrophic event, including but not limited to fire or flooding, internal or external to the predominantly enclosed space.

In some embodiments this information may support any single or any combination of locally or remotely alerting humans, alerting rescue units, activating countermeasures, uploading at least partially said sensor data to off-site computers, determining the cause(s) of said catastrophic event, determining liability, determining insure payments, determining insurance premiums.

A conditional climate control system is presented for maximizing the comfort level of the climate within a building while minimizing the usage of an on-demand energy source. An energy reserve created by an intermittent energy source or sources is monitored, and when it has surpassed a predetermined threshold level the climate conditions of a building are set to more desirable but energy intensive levels from energy-saving levels.
