DOE-2 Reference Manual Version 2.1 - DOE2.com

It is strongly recommended that the instructions that specify thebuilding envelope, along with the ?chedule and assignment instructions,be entered at the beginning of the LOADS input. This practice will precludesuch common errors as referencing U-names not previously defined.Therefore, enter the following instructions next.MATERIALLAYERSCONSTRUCTIONAs an alternative to the entry of one or more of the above instructions,a selection may be made from the DOE-2 Library of MATERIALs, LAYERS, andCONSTRUCTIONs, BDLLIB. In this case, proper code-words must be enteredin a LAYERS, CONSTRUCTION, or EXTERIOR-WALL instruction.Occupancy, lighting, infiltration, and equipment schedules are enterednext.DAY-SCHEDULEWEEK-SCHE DU LESCHEDULEAfter all the schedules have been specified, each thermal zone* withinthe building should be specified. The selection of thermal zoneboundaries should be done with consideration of the secondary HVACsystems. Every space in the LOADS program must be physically identicalto every zone in the SYSTEMS program.Common space conditions can be specified by the following instruction.SPACE-CONDITIONSThis instruction simplifies input, because it can be referenced inseveral spaces. Thus the values under it do not have to be repeated.The next instruction is required to define each space.SPACEindicates to the LDL Processor that the following instructions willdefine a thermal zone. Thus, immediately following each SPACE instruction,the appropriate thermal boundaries for that space must be entered.To do this, use the following commands.as appropriate.theEXTERIOR WALL (or ROOF)INTERIOR WALLUNDERGROUND-WALL (or UNDERGROUND-FLOOR)Any fenestration or entryway should be defined using*In this text, the words "thermal zone," "zone," and "space" aresynonymous and are interchangeable.I II.4 (Revised 5/81)
