Ivan, If it is essentially outdoors, it should not be a thermal zone. The luminaire can be accounted for as Exterior electrical equipment. James V Dirkes II, PE, BEMP, LEED AP From: EnergyPlus_Support@xxxxxxxxxxxxxxx [mailto:EnergyPlus_Support@xxxxxxxxxxxxxxx] Hi everyone, i've been modelling a apartment with a small terrace. This terrace is opened to outside and have one luminaire. This terrace need to be a thermal zone, or can i consider a component block modelling? Best regards. Técg.
