A single performance indicator, the solar transmittance factor (STF), has been proposed in previous works, together with derived index (STI). It is aimed at evaluating summer of roofing system and allowing selection most effective mix surface mass properties. easily calculated from low-level indicators such as U-value, module periodic thermal transmittance, reflectance. In present work, correla...

We propose a spectral prediction model for predicting the reflectance and transmittance of recto-verso halftone prints. A recto-verso halftone print is modeled as a diffusing substrate surrounded by two inked interfaces in contact with air (or with another medium). The interaction of light with the print comprises three components: (a) the attenuation of the incident light penetrating the print...

The vertical polarization distribution pattern of sea fog multilayer media and skylight in the atmosphere is explored. To change complicated maritime environment, simplified double layer structure employed, scattering coefficients uniform medium are derived using Rayleigh Mie methods, respectively. Using adding-doubling method (RT3) based on vector radiation transmission equation, between two l...

In this paper we address the design of large roof structures by integrating interdisciplinary performance evaluations in the early stages of the design process. Specific focus is given to structural and solar energy related performances. Geometry is stressed as a key interface between the different disciplines. Parametric modelling is used to automatically create geometric design alternatives. ...

Broadband atmospheric transmittance is a key component in many broadband clear-sky solar radiation models, whose performance inevitably bound to the goodness of their parameterizations. A element development these parameterizations, that has been traditionally overlooked, spectral integration range. The related scientific literature reveals two different approaches have proposed, but they vague...
