Solar Radiation Data Manual for Buildings Solar Radiation Data Manual for Buildings Appendix-Methodology • • • • • • • This Appendix describes the methods used to calculate the monthly and yearly averages of incident and transmitted solar radiation and the illuminanace diurnal profiles. It also describes how data uncertainities were determined and how the climatic information was derived.
The incident solar radiation for a horizontal window and vertical windows facing north, east, south, and west was determined using models and hourly data from the 1961-1990 National Solar Radiation Data Base (NSRDB). Global solar radiation. The incident global solar radiation (I) received by a surface, such as a window, is a combination of direct beam radiation ( ), sky radiation ( ), and radiation reflected from the ground in front of the surface ( ). The following equation can be used to calculate incident global solar radiation: equation (1) where is the incident angle of the sun's rays to the surface.
The incident angle is a function of the sun's position in the sky and the orientation of the surface. Algorithms presented by Menicucci and Fernandez (1988) were used to compute incident angles. Hourly values of direct beam solar radiation from the NSRDB were used to determine the direct beam contribution ( ) for each hour. Resident Evil 2 Platinum Pc Iso Extractor here. Except for the first and last daylight hour, incident angles were calculated at the midpoint of the hour. For the first and last daylight hour, incident angles were calculated at the midpoint of the period during the hour when the sun was above the horizon. The sky radiation ( ) received by the surface was calculated using an anisotropic diffuse radiation model developed by Perez et al.
The model determined the sky radiation striking the surface using hourly values (from the NSRDB) of diffuse horizontal and direct beam solar radiation. Other inputs to the model included the sun's incident angle to the surface, the surface tilt angle from horizontal, and the sun's zenith angle. The Perez et al. Model is an improved and refined version of their original model that was recommended by the International Energy Agency for calculating diffuse radiation for tilted surfaces ( Hay and McKay 1988). The following equation is the Perez et al. Model for diffuse sky radiation for a surface: equation (2) where = diffuse solar horizontal radiation = circumsolar anisotropy coefficient, function of sky condition = horizon/zenith anisotropy coefficient, function of sky condition = tilt of the collector from the horizontal = 0 or the cosine of the incident angle, whichever is greater = 0.087 or the cosine of the solar zenith angle, whichever is greater.
The model coefficients and are organized as an array of values that are selected for use depending on the solar zenith angle, the sky's clearness, and the sky's brightness. Perez et al.(1990) describe completely the manner in which this is done. The ground-reflected radiation ( ) received by a surface is assumed isotropic and is a function of the global horizontal radiation ( ), the tilt of the surface from the horizontal ( ), and the ground reflectivity or albedo ( ).
