Päivänvalosäätimet

Päivänvalosäätimet, also known as daylighting controls, are a system designed to optimize the use of natural daylight within buildings. Their primary function is to reduce the reliance on artificial lighting by automatically adjusting electric light output in response to the amount of available natural light. This integration aims to enhance occupant comfort, reduce energy consumption, and contribute to a more sustainable building environment.

The core principle behind päivänvalosäätimet involves sensors, typically photosensors, strategically placed within a space to measure ambient light levels. These sensors are connected to a control system, which in turn communicates with dimmable or switchable lighting fixtures. When the sensors detect sufficient natural light, the control system gradually reduces the intensity of the electric lights or switches them off entirely. Conversely, as natural light diminishes, the system increases the artificial light output to maintain a consistent and desired illuminance level.

Different types of päivänvalosäätimet exist, ranging from simple on/off systems to more sophisticated proportional dimming controls. Some advanced systems can also incorporate features like time scheduling, occupancy sensing, and integration with building management systems to further refine energy savings and user experience. The effective implementation of these controls requires careful consideration of building orientation, window design, and the specific lighting needs of different areas within a building.
