Abstract: Embodiments of the disclosure provide for determination and/or notifying of when an asset requires maintenance. Such embodiments enable outputting notifications in circumstances where tracked data for operations of an asset indicate or are predicted to violate particular thresholds. Some embodiments receive a feedback data set for an asset, identify a command data set for the asset, determine a delay value based at least in part on the feedback data set and the command data set, determine a command-feedback difference value based at least in part on the feedback data set and the command data set, and output a degradation indicator based at least in part on the delay value and the command-feedback difference value.

Abstract: Methods, apparatuses, and computer program products are disclosed for performing air quality maintenance. An example method include receiving an air quality dataset and generating a quality tendency projection based upon the air quality dataset that includes a quality rate of change. In an instance in which the quality tendency projection exceeds a prediction threshold and the quality rate of change exceeds a pollutant rate increase threshold, the method performs performing air degradation analysis. In an instance in which the quality tendency projection exceeds a warning threshold and the quality rate of change exceeds a pollutant rate decrease threshold, the method performs ventilation analysis.

Abstract: A hydronic heating system that may depend on pressure in the system for smooth operation. The pressure may be monitored. Pressure in the system may indicate health of the heating system. Certain pressures or variations of pressures may indicate one or more conditions in the system which may be good or adverse. An example of an adverse condition may be leakage of fluid from the system. Analyzes of pressures detected in the heating system may be performed by a computer programmed to indicate conditions of the system that are reflected by the detected pressures.

Abstract: A computer implemented method optimizes a utility plant having multiple devices to convert input energy into output energy for a building. The method includes dividing a utility plant scheduling interval into several control intervals and for each control interval, obtaining a difference between a desired and a measured in-building condition controlled by output power from the utility plant, obtaining current values of multiple factors that influence operation of the utility plant, determining a new power demand of the building expected to decrease the difference, and finding set points for the multiple devices that satisfy the new power demand, take into account response times of the devices and their capacities, and optimize utility plant operation costs.

Abstract: A sun blinds system for light conditions control in a room or space. The space or room with one or more windows may have a set of sun blinds that have a position to cover the whole or part of the window to prevent to an extent, as desired by an occupant or occupants, sunlight from entering the space. Parameters such as space light level, glare, weather conditions, time of year and day, cloud cover, space temperature and occupancy may be entered in a database. A learning supervisor may determine the position of the sun blinds in view of the parameters and previous manual sun blinds' settings by occupants, and provide the position to a sun blinds controller.

Abstract: A system incorporating a camera sensor situated in a room having walls with windows and sun blinds. The sun blinds may control outdoor light to the room. Indoor light sources may provide artificial light in the room. A controller may receive signals from the camera sensor. The controller may estimate a presence of occupants and provide control signals to the sun blinds and light sources. A room temperature sensor and an HVAC system may be connected to the controller. A preset temperature, which may depend on occupancy, in the room or zone may be achieved with various kinds of heating or cooling. At the same time, outdoor light and indoor artificial light may be controlled to obtain a preset intensity of lighting in the room, which may depend on occupancy, in a manner to achieve a minimum cost of energy used by the HVAC and the light sources.

Abstract: One embodiment of the application provides a method of forecasting utility demand of a utility consuming entity for a future time period. The method includes: selecting a utility demand matrix from a set of utility demand matrixes as a function of a future date, wherein the set of utility demand matrixes are classified by type-of-day, and representing a relation of past utility demand of the entity to time-in-day interval and outdoor temperature in the vicinity of the entity during the type-of-day; identifying a utility demand element from the utility demand matrix as a function of a future time-in-day and a known factor (e.g., future outdoor temperature) thereof; and generating a utility demand forecast of the entity for the future time period as a function of the identified utility demand element.

Abstract: Utility demand is continuously monitored and monitoring data is aggregated and organized. The results are presented visually as a Utility Demand Footprint, referred to herein as a UDF. A UDF characterizes the utility demand in relation to selected influencing factors over a selected time period and over selected time intervals within the time period. In a preferred embodiment, the UDF is generated using a computer program and includes color mapping for simplifying analysis of the information displayed in the UDF. The footprint generation may be performed for a particular time period in which the demand essentially keeps its character (e.g., summer) or may be periodically updated (e.g., every day, every hour, etc.) to capture the latest changes.
