Second case study on the use of irradiance ratios

The dataset included in this folder contains the results of a second case study of the use of irradiance ratios for calculating the effect of reflections on obstruction in the ESP-r building performance simulation platform via the Modish procedure, by the author. The materials which are necessary to reproduce the simulations in Esp-r (version 13.4 or later) and EnergyPlus (version 9.5) are also included. Finally, the definitive results of the first case study are included.Modish is a program for bringing into account the reflective effect
of solar obstructions on solar gains in an ESP-r building model on the
basis of the irradiance ratios combining the direct unreflected
radiation on a surface, as calculated by ESP-r, and the total radiation
on the same surface calculated by the means of Radiance.
The
Modish procedure has been implemented in the Perl library
Sim::OPT::Modish (https://metacpan.org/pod/distribution/Sim-OPT/lib/Sim/OPT/Modish.pm). The library originally output hourly shading factor
results relative to the average day of each month, and has subsequently
been modified to work with hourly data unlinked from the average
monthly model. This latter version of the procedure has been integrated
in the state-of-the-art building performance simulation application
ESP-r
(http://www.strath.ac.uk/research/energysystemsresearchunit/applications/esp-r/).
The most recent version of Modish is currently available in the ESP-r
source code. The Sim::OPT::Modish version will be kept updated with the
ESP-r-embedded Modish version.
