Question: Do annual daylight simulations use the weather file associated to thermal model on site level? Answer: Yes, the weather file is used to produce a matrix of sky patch values using the Perez all weather model. The input file contains a short header with the site parameters followed by the month, day, standard time, direct normal and diffuse horizontal irradiance values, one time step per line (8760 lines).
