Research Abstract	Two models for estimating global spectral solar radiation and diffuse spectral solar radiation from TRYs (test reference years) data have been developed in order to consider an effect of spectral distribution of solar radiation in building energy simulation. These models can output spectral solar radiation in wave range from visible to near infrared under all weather conditions. The wavelength interval of the calculation is 2 nm in wave range from 350nm to 1700nm. Also an integrated near infrared solar radiation can be calculated in wave range from 1700nm to 3000nm. Five weather parameters, such as temperature, humidity, global solar radiation, beam solar radiation and diffuse solar radiation, are used as input data of the models so that the spectral solar radiation can be calculated from TRYs data.
