Abstract— Considering the work requirements and the current way of life, human beings spend more and more hours a day indoors. Therefore, it is essential to make an appropriate optimization of windows in architecture, to reduce energy consumption and its impact on the environment, as well as an improvement in the health and wellness of the occupants by promoting a suitable circadian cycle. This study aims to simplify the calculation of daylighting in interior spaces, establishing a more precise link between one of the most common static metrics, the Daylight Factor (DF) and another of the main dynamic metrics, the Daylight Autonomy (DA), linking them through the Minimum Daylight Autonomy (DAm), allowing to obtain precise dynamic daylighting values without the need for a sophisticated and slow computational simulation. In this way, a work methodology is proposed and applied as a practical example in 6 European capital cities with different latitudes and sky types, quantifying the relationship between both metrics for each of them and analysing the current tendencies of the results. The work concludes with a first transposition of the results of the study samples, allowing its easy and fast application of this link to any professional of Architecture.

 
Index Terms—Natural lighting, dynamic metrics, energy efficiency, architecture and health, minimum daylight autonomy, weighting factors.
