State of the art in lighting simulation for building science: a literature review

1 post / 0 new

This paper, authored by Carlos E. Ochoaa, Myriam B.C. Aries & Jan L.M.
Hensen and published in IBPSA's official journal, the Journal of
Building Performance Simulation, examines the current state of the art
in lighting simulation related to building science research. Discussion
on historical developments and main modelling approaches is followed by
describing lighting simulation within the design process, where it is
applied beyond presentation renderings. Works are grouped using the main
aspects of a program (input, modelling and output). Lighting simulation
currently focuses on representing accurately a large number of common
situations encountered by building designers and researchers. Existing
models apply roughly the same theoretical algorithms and calculation
aids, limiting representation of certain physical phenomena. Although
some models can be used for element design, they are not practical
enough to develop or prototype new, untested elements. Elaborate
building components require separate analysis through complex simulation
aids. Few tools support the early architectural design process.
Simplification applies when integrating lighting simulation to
whole-building simulation. Input quality affects accuracy, while output
needs careful expert interpretation.
