A Python Library for Radiance Matrix-based Simulation Control and EnergyPlus Integration

Radiance matrix-based methods enable efficient
parametric simulations, allowing users to vary sky
conditions, fenestration systems, and other model
parameters at a minimal cost to computation. However,
the steep learning curve and complex workflow hinder
the widespread adoption of matrix-based methods. The
frads Python library with a series of command-line tools
was developed to automate the entire matrix-based
simulation process, lowering entry barriers and reducing
human error. Co-simulation between EnergyPlus and
Radiance was also enabled using the Python library from
EnergyPlus.
