Daylight is a basic human need. The feel-good hormone serotonin, for example, can only be produced if there is sufficient natural light. With the new EU standard EN 17037, there is now, for the first time since 2019, a Europe-wide recommendation for minimum standards of daylight planning in buildings. Since its foundation, Heliobus® has focused on optimal light supply and daylight quality in all its daylight systems and their use.
The first EU standard on daylight in buildings
With DIN EN 17037, a European standard on daylight in indoor spaces has been published for the first time. The requirements are becoming more stringent and can possibly only be mastered by specialist planners. The standard prescribes both the quantity and quality of daylight in buildings. For information purposes, two calculation methods are described: The first is based on the determination of a daylight quotient, the second on the dynamic determination of the annual daylighting according to the climatic conditions on site. The new daylighting standard specifies criteria for assessing the supply of daylight, the view, the duration of tanning and glare in rooms. For this purpose, characteristic values are defined in the annex that must be fulfilled in each case in order to achieve the recommendation levels "Low", "Medium" or "High". The recommendation levels for daylighting are based on a level to be aimed for in planning, which is to be selected depending on the use.

Challenge
Providing an underground sports hall below the break area with sufficient daylight
Proposed solution Heliobus AG
With the use of numerous, accessible skylights, the sports hall is supplied with daylight, while no areas are lost on the break area. For the optimal illumination of the sports hall with daylight, Heliobus AG carried out daylight calculations according to the EU standard (Daylight in buildings, EN 17 037). Based on the calculations, the number and dimensions of the skylights were further proposed.
