The paper presents a student guide on how to implement surface to surface radiation within COMSOL Multiphysics® software for case studies found within the built environment. We included four benchmarks: (1) Radiation in a triangular cavity with infinite length; (2) Radiation between two infinitely long rectangular plates; (3) Radiation in a three dimensional rectangular enclosure; (4) Radiation in an ice rink building. We conclude that COMSOL® benchmark results are satisfactory.
