Abstract: An airflow measurement system configured to be received in a duct of a heating, ventilating and air conditioning (HVAC) system is provided. The air flow measurement system includes a housing, and a plurality of cells positioned in the housing, the plurality of cells being configured such that air flows through the plurality of cells when the flow measurement system is positioned in the duct of the HVAC system, wherein at least one of the cells includes a self-heated thermistor.

Abstract: Methods, systems and computer program products are provided for controlling a climate in a building. Sensed data is received at a local processor in the building. The sensed data is associated with the climate in the building, weather outside the building and/or occupants of the building. The received sensed data is compared at the local processor with corresponding predictive data associated with the climate in the building, weather outside the building and/or occupants of the building. One or more parameters associated with the climate of the building is adjusted at the local processor based on a result of the comparison of the received sensed data and the predictive data.
