Updates to the lighting section include modified lighting power allowance requirement for interior and exterior lights; and modifications to lighting control requirements based on daylighting and occupancy sensors. In the mechanical section, minimum efficiency requirements for many types of HVAC equipment are revised.
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.
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.
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]
Lighting can be turned on, off, or dimmed with a building automation or lighting control system based on time of day, or on occupancy sensor, photosensors and timers. [9] One typical example is to turn the lights in a space on for a half-hour since the last motion was sensed.
Control devices can include input devices such as daylight sensors, passive infrared room occupancy sensors, and manual lighting controls, or they can be application controllers that are the "brains" of the system - using information to make decisions and control the lights and other devices. Control devices can also combine the functionality ...
