Tanning study
A tanning analysis is the methodological core of a tanning study . Tanning studies are part of a land-use plan for the creation of a development plan . DIN 5034 - Daylight in interiors, Part 1, Paragraph 4 defines the qualitative and quantitative minimum requirements for lighting conditions in living spaces.
method
A three-dimensional computer model of the examination room is created as a working basis for the creation of an exact tanning analysis. This model includes the topographical situation, the altitude above sea level , the georeferencing and the structural and open space environment. The objects to be examined are integrated into this environment in terms of position, orientation, height and volume. By knowing the exact position in three-dimensional space, the exact position of the sun in relation to the examination space can be determined at any specific time. This reference makes it possible to determine the course of the light and thus also the shadow.
Viewing times
In order to be able to give a representative statement about the tanning in the course of the year, three observation times that are significant for the year are selected. June 21st is the day with the highest position of the sun and also the day with the longest sunshine of over 16 hours in Central Europe. It is representative of the slightest shadow cast. The time of the equinox, which occurs on both March 21st and September 21st, stands for the mean annual shadow course. For the representative point in time of minimum solar irradiation, due to the stipulation by DIN 5034, not the day of the winter solstice, December 21st, but a mean winter day, January 17th.
simulation
In order to examine the shading effect of the objects to be examined on the environment or on themselves, the positions of the sun at certain times are simulated by means of computer simulation and a shadow image of the examination area is calculated. These shadows are displayed on the defined viewing days at viewing intervals adapted to the course of the sun over the course of the day in the site plan. On the basis of these shadow progression images, the effect of the objects to be examined with regard to the tanning can be precisely analyzed.
Norms and standards
- DIN 5034 daylight indoors
In Germany, the requirements with regard to the lighting of rooms are also laid down in the workplace guidelines and in the state building regulations.
