Ru 1 es:Example:to the space. It also depends on the hourly varying proportionsof direct and diffuse solar radiation entering thespace.Since the user can enter only one set of SOLAR-FRACTIONs fora SPACE, the SOLAR-FRACTIONs should be chosen to represent atime-average over the intended RUN-PERIOD of the analysis,with emphasis given to those times of day and seasons of theyear when solar gain is greatest.Note: SOLAR-FRACTION is not affected by MULTIPLIER. Itapplies to the surface area after multipliCation.1. A SPACE instruction must precede any EXTERIOR-WALL or ROOFinstructions.2. An EXTERIOR-WALL or ROOF instruction must immediately precede theWINDOW and DOOR instructions that describe the windows and doors inthe wall.3. The area (HEIGHT times WIDTH) of the EXTERIOR-WALL or ROOF must beequal to or greater than the area entered for the WINDOW and DOORinstructions associated with the EXTERIOR-WALL or ROOF.4. If a code-word is not chosen from Ref. 5, a CONSTRUCTION instructionmust precede an EXTERIOR-WALL or ROOF instruction.5. When the LOCATION keyword is used, the X, Y, Z, AZIMUTH, HEIGHT, andWIDTH keywords should not be used.6. GND-FORM-FACTOR and SKY-FORM-FACTOR must be entered together or notat all. No entry results in program calculation of these values.Using AREA and VOLUME in the SPACE instruction:NWALL = EXTERIOR-WALLCONSTRUCTION= BRICKGND-REFLECTANCE = 0.3SKY-FORM-FACTOR = 0.5GND-FORM-FACTOR = 0.5INF-COEF = 0.002SHADING-DIVISION = 30MULTIPLIER = 2HEIGHT = 10.WIDTH = 30.or if using SHAPE, HEIGHT, WIDTH, and DEPTH in the SPACE instruction:II 1.104 (Revised 5/81)
