  • Patent number: 8660708
    Abstract: A system provides space conditioning zone control in a building for efficient energy use and conservation of energy resources. The system includes an energy transfer module coupled to a solar thermal system to receive a first airflow and an auxiliary thermal module coupled to the energy transfer module for processing a return airflow to provide a conditioned airflow for one or more spatial zones. The system further includes a zone controller coupled directly to the auxiliary thermal module and a thermostat in each spatial zone for operating the auxiliary thermal module. Furthermore, the system includes a master control module wirelessly communicated with each thermostat and configured to operate the energy transfer module. The master control module initiates a transfer of the first airflow based upon a first setpoint before the zone controller initiates a generation and transfer of the conditioned airflow based upon a second setpoint.

  • Publication number: 20120295534
    Abstract: A method for providing a ventilation control compliant with an adopted ventilation standard for efficient energy usage and conservation of energy resources. The method includes operating a home energy system to generate solar energy within a daily active period and draw ambient fresh air, and setting a daily ventilation period as a fractional period of a day. The daily ventilation period is substantially coordinated with the daily active period during a heating/cooling period for the home. Additionally, the method includes determining a target volume in compliance with the adopted ventilation standard and determining a flow rate for delivering the fresh air during the daily ventilation period. Moreover, the method includes monitoring an accumulated total ventilation volume of the delivered fresh air until the accumulated total ventilation volume is within a vicinity of a target volume.

  • Publication number: 20110257795
    Abstract: A system for controlling solar energy utilization for efficient energy usage and conservation of energy resources for providing space conditioning and home ventilation. The system includes a control module configured to operate a solar energy system for collecting a flow of fresh air for utilizing thermal energy converted by the solar energy system. Additionally, the system includes a thermostat module directly coupled with an HVAC system to for controlling a delivery of a conditioned airflow. The thermostat device couples wirelessly to the control module. Further, the system includes a graphic user interface operably communicating with the control module remotely via a network hub. The graphic user interface device is configured to set modes of operation for the thermostat module and configured to communicate with the thermostat module for transmitting control information, modes of operation, and temperature information of the building structure to the control module via a wireless transmission.

  • Publication number: 20110223850
    Abstract: A method provides a ventilation control compliant with an adopted ventilation standard for efficient energy usage and conservation of energy resources. The method includes operating a home energy system to generate solar energy within a daily active period and draw fresh air from an ambient region, setting a daily ventilation period as a fractional period of a day, the ventilation period being coincident with the active period during a heating period for the home or a time period after the active period during a cooling period for the home, determining a target volume, determining a flow rate for delivering the fresh air during the ventilation period, performing ventilation in the ventilation period to deliver the fresh air into the home using the flow rate, and monitoring an accumulated total ventilation volume of the delivered fresh air until the accumulated total ventilation volume is within a vicinity of a target volume.
