  2. Occupant-centric building controls - Wikipedia

    en.wikipedia.org/wiki/Occupant-centric_building...

    Examples of implicit occupancy sensors includes CO 2 sensors and Wi-Fi-connected device count. [1] The selection of occupancy sensing devices depends on the size of the space being monitored, the budget for sensors, the desired accuracy, the goal of the sensor (detecting occupant presence or count), and security considerations.

  3. Occupancy sensor - Wikipedia

    en.wikipedia.org/wiki/Occupancy_sensor

    Occupancy sensor types include: PIR sensors, which work on heat difference detection, measuring infrared radiation.Inside the device is a pyroelectric sensor which can detect the sudden presence of objects (such as humans) who radiate a temperature different from the temperature of the background, such as the room temperature of a wall.

  4. Lighting control system - Wikipedia

    en.wikipedia.org/wiki/Lighting_control_system

    In the paper "Energy savings due to occupancy sensors and personal controls: a pilot field study", Galasiu, A.D. and Newsham, G.R have confirmed that automatic lighting systems including occupancy sensors and individual (personal) controls are suitable for open-plan office environments and can save a significant amount of energy (about 32% ...

  5. United States lighting energy policy - Wikipedia

    en.wikipedia.org/wiki/United_States_lighting...

    Lighting control devices and systems must be functionally tested (this includes occupancy sensors, time switches, programmable schedule controls and photosensors) [20] Advanced lighting control is an effort made by ASHRAE 90.1-2010 to significantly reduce the energy used for lighting by commercial buildings. [20]

  6. Building automation - Wikipedia

    en.wikipedia.org/wiki/Building_automation

    Building automation (BAS), also known as building management system (BMS) or building energy management system (BEMS), is the automatic centralized control of a building's HVAC (heating, ventilation and air conditioning), electrical, lighting, shading, access control, security systems, and other interrelated systems.

  7. Home automation - Wikipedia

    en.wikipedia.org/wiki/Home_automation

    Occupancy-aware control system: it is possible to sense the occupancy of the home using smart meters [11] and environmental sensors like CO 2 sensors, [12] which can be integrated into the building automation system to trigger automatic responses for energy efficiency and building comfort applications.

  8. Daylight harvesting - Wikipedia

    en.wikipedia.org/wiki/Daylight_harvesting

    When sensors were placed on desktops in an office building, an penalty of 24% on energy saving occurred. [7] In both the open- and closed-loop configurations, the signal from the photosensor must be carefully calibrated to accurately indicate the effect of exterior daylight variations on the light level on 'important function' areas in the space.

  9. Energy conservation - Wikipedia

    en.wikipedia.org/wiki/Energy_conservation

    Occupancy sensors can conserve energy by turning off appliances in ... and systematic energy-saving plans. [5] ... energy savings in Europe can reach 67% of the 2019 ...
