Daylight in interiors - Part 3: Calculation
|Publication Date:||1 February 2007|
|ICS Code (Interior lighting):||91.160.10|
This standard specifies the method of calculating the expected illuminances, daylight factors, periods of use and usable luminous exposures for specific points in interiors, based on the relationships given in DIN 5034-2. It is used to determine whether, given specific window or rooflight dimensions, the minimum values for the daylight factor as specified in DIN 5034-1 are ensured indoors. Of all the various known calculation methods, this standard recommends a method that has been sufficiently proven in practice, in order to ensure that the results of daylight calculations are comparable.
The calculation of radiation from the sun and the sky entering through windows and rooflights is important for investigations relating to air-conditioning and economic considerations.
