[hal-01088902] Evolution of CODYRUN from thermal simulation to coupled thermal and daylight simulation software

CODYRUN is a multi-zone software integrating thermal building simulation, airflow, and pollutant transfer. Described in numerous publications, this softwarewas originally used forthe passive designof buildings, both for research and teaching purposes.In this context, the datatreatedwere mainly concerned with volumes (zones), surfaces andthicknesses (walls andwindows), materials, and systems, with the aim to determine temperatures,heat fluxes,energy consumed, air transfers, and so on. The questionthus arose as tothe integration ofindoor lighting conditions into the simulation. Hence, previousdata structureshad to beamended to incorporatethe spatial positioning ofentities (walls, windows, and artificial lighting sources) throughvertexes. A set ofprocedureswasalso developed for polygons as well as calculatingnatural and artificial lighting. The results ofthis new daylighting modulewere thencompared with otherresultsof simulation codes and experimentalcases both in artificialand naturalenvironments. Excellent agreements were obtained, such as the values for luminous efficiencies ina tropical and humid climate. A simulation exercise was conducted in a classroom located in Reunion Island (French overseas territory in the Indian Ocean), thus confirming the interest for thermal and daylighting designsin low-energy buildings.
