Program for keeping into account the solar reflections from obstructions in ESP-r on the basis of the irradiance ratios

Modish is a program for bringing into account the reflective effect of the solar obstructions on solar gains in an ESP-r building model on the basis of irradiance ratios. Those ratios are obtained combining the direct radiation on a surface and the total radiation on it calculated by the means of Radiance. Modish is written in Perl and can be installed from the CPAN with the command: sudo cpanm Sim::OPT::Modish
