Solar heat load calculator
this mathematical model calculates cumulative Power of incident Solar radiation over a day. It uses date/time, Latitude/logitude as external/user controlled parameters and takes in account the air mass reduction factor (absorbance of energy by the atmosphere).
Incident sunlight data is used for elaborating facade paneling optimized for maximum daylight entry and minimum accumulation of solar heat. The mesh geometry can be replaced by any geometrical building representation.
