Designing With Daylight
Daylight-responsive lighting controls (aka, daylighting or daylight harvesting) are interior automatic controls that reduce electric lighting energy consumption in response to daylight contribution levels. This control strategy has been a staple in commercial buildings due to energy codes.
Control of daylight and direct sun is typically manual. If automatic control is used, the criterion used is typically to avoid direct sunlight entering the space and control is often based on illuminance or irradiance of the façade. Few experimental systems have been designed to control interior daylight conditions, direct sun, and other criteria related to visual comfort.
Dynamic Daylighting Systems
Dynamic daylighting systems represent a cutting-edge approach to architectural design that leverages intelligent technologies to optimize natural light in built environments. By integrating responsive lighting controls , automated shading systems , and innovative materials, dynamic daylighting systems enhance the quality of natural light, improve energy efficiency, and create healthier and more ...
As we can see from the illustration, Automatic Daylighting Control Systems Design has many fascinating aspects to explore.
Automatic daylighting control is an energy-savings strategy used with increasing frequency in high performance building design . (1) This type of control generally includes a photosensor that automatically dims or switches electric lighting to a lower energy state in response to natural daylight. Considerable effort is often expended on architectural and lighting design to bring in more natural ...

Automated Daylighting Controls for Sidelighted Areas (9.4.1.4) The lamps for general lighting must be controlled by at least one multilevel daylight control in any enclosed space that has more than 250 ft2 of window lit area.
Abstract Building control systems have become essential to ensure both energy savings and user comfort. Specifically, daylight-linked control systems (DLC systems ) allow interior conditions to be adapted to the preferences of each user based on the availability of daylight.

This review summarizes the state-of-the-art articial intelligence techniques in daylighting fi controllers to optimize the performance of conventional photosensor-based control and camera-based control in commercial buildings.
To maintain the desired light level, continuous daylighting involves smooth, continuous dimming from low to high. Continuous daylighting adjusts lights based on the amount of daylight that is always present in the space, ensuring that the minimum light level is met without over-lighting the space (as opposed to switched and bi-level daylighting ).
