Abstract
It is accepted that the visual comfort in schools depends on the quality of the whole visual environment. This leads to the concern
upon the quality and quantity of lighting. Currently in Iran, in order to calculate energy transfer for public buildings a coefficient is
usually used. This coefficient considers the rate of sunlight energy absorption in these kinds of buildings. To increase the degree of
accuracy in the calculation mentioned above, the authors suggest a simulation programme that can do the job precisely and
accordingly. It seems that, in order to calculate the energy requirements of school buildings in Iran for heating, cooling and lighting,
it is better to use a simulation programme, too. In fact, this paper considers details of lighting as part of a comprehensive programme
and Iran schools design requirements for lighting. As we will see, this research describes the method of calculation of daylighting,
which is used in the part of lighting simulation programme. Effective daylighting design requires consideration of different factors
such as daylight factor, luminous efficacy of solar radiation, orientation factor, glass transmittance factor, average reflectance of
material and etc. which are need for calculation of exterior and interior luminance. They are discussed in details in this paper.
