is varied with respect to time and quantity of people bythe PEOPLE-SCHEDULE and NUMBER-OF-PEOPLE. An alternativemethod of specifying people heat gain is to use PEOPLE-HG­LAT and PEOPLE-HG-SENS.PEOPLE-HG-LATPEOPLE-HG-SENSis the maximum latent heat gain per person to the space bythe occupants.is the maximum sensible heat gain per person to the spaceby the occupants.LIGHTING-SCHEDULE identifies the schedule that will specify the space overheadlighting schedule. Schedule inputs are fractions ofmaximum 1 ighting energy input (see LIGHTING-KW or LIGHTIN.G­W/SQFT; see also LIGHTING-TYPE and LIGHT-TO-SPACE). Ifnot specified, the LIGHTING-SCHEDULE value will default tozero. This will result in simulation with no lighting,even if lighting is specified by keywords LIGHTING-KW orLIGHTING-W/SQFT, etc.LIGHTING-TYPEis used to specify the type of overhead 1 ighting used inthe space (see Fig. II1.14). The following tableidentifies the code-words used.Code-wordSUS-FLUORREC-FLUOR-NVREC-FLUOR-RVRE C-F L UOR -RS VINCANDLIGHTING-TYPESuspended fluorescentRecessed fluorescent - notventedRecessed fluorescent ventedto return airRecessed fluorescent ventedto supply and return airIncandescentFor mixed types of lighting within the same space, therecommended procedure is to select the dominant type andadjust the percentage of heat produced by the 1 ighting,using the LIGHT-TO-SPACE keyword.LIGHTING-KWis the maxirrum aJ1X)unt of electrical energy required tooperate the main or overhead lights within the SPACE andis not necessarily the sensible heat added by the lightsto the SPACE (see LIGHT-TO-SPACE). The actual space lightingenergy required by the SPACE during any given hour isthe value assigned to this keyword multiplied by the fractionalvalue aSSigned for that hour (see LIGHTING-SCHEDULE).If both LIGHTING-KW and LIGHTING-W/SQFT are specified, theprogram adds the values.Note that the values for LlGHTING-KW and LlGHTING-W/SQFT areaJ1X)unts of electricity consumed, not the amount ofillumination produced.111.44 (Rev ised 5/81)
