dagsljusfaktor

Dagsljusfaktor, also known as Daylight Factor, is a measure used in architecture and urban planning to quantify the amount of natural light that enters a building or space. It is defined as the ratio of the illuminance on a horizontal surface to the illuminance on a vertical surface, both measured at the same point. This factor is crucial for designing spaces that maximize natural light, thereby reducing the need for artificial lighting and improving energy efficiency.

The Daylight Factor is typically expressed as a percentage and can vary significantly depending on the location, time of year, and orientation of the building. For example, a high Daylight Factor indicates that a space receives a significant amount of natural light, while a low Daylight Factor suggests that the space is more reliant on artificial lighting.

In practical terms, the Daylight Factor is used to design buildings that are well-lit and comfortable for occupants. It helps architects and planners to optimize the placement of windows, skylights, and other light sources to ensure that natural light is distributed evenly throughout the space. Additionally, it can be used to assess the potential for glare and to design shading systems that control the amount of light entering the building.

The Daylight Factor is also an important consideration in urban planning, as it can influence the overall quality of the urban environment. By designing buildings with high Daylight Factors, cities can create more pleasant and sustainable spaces that reduce energy consumption and improve the well-being of their residents.
