DOE-2 Reference Manual Version 2.1 - DOE2.com

C. WEATHER FILESThree groups of weather files are available in the 00E-2 library. Inaddition, several types of weather files can be processed by the weather processingprograms to produce files for use by 00E-2.1. TRYThe 00E-2 library has one year of data for each of 60 different US weatherstations selected according to the ASHRAE Test Reference Year (TRY) procedure.*Table VIII.1 lists the TRY cities now available and Appendix VIII.O containsweather data summaries for these cities (except St. Louis, r~issouri).A manual for the TRY data, published by the National Climatic Center inAsheville, North Carolina, is reproduced in Appendix VIll.A. Summaries of theTRY data for each city are included in Appendix VIII.E.The user should exercise caution in applying TRY data. The TRY should bereliable for making comparisons of design or retrofit options. However, aspointed out in the TRY Manual, a TRY is not considered sufficiently typical toyield reliable estimates of average energy requirements over several years.2. California, CTZOne year of data for each of 16 climate zones in the State of Californiais included. These data were assembled by Loren Crow for the California EnergyResources Conservation and Development Commission.A map showing the boundaries of the California climate zones is given inFig. VIII.1. Table VIII.2 gives the 00E-2 file name and the major cities foreach of the 16 zones.3. TMYThe 00E-2 library contains weather files for 26 US weather stations inthe Typical Meteorological Year (TMY) format. Appendix VIII.B contains adescription of the TMY tapes.4. OthersThe 00E-2 weather processing programs (see Appendix VIII.C) can processTRY, TMY, CTZ, CD144, T01440, and Weather Year for Energy Computation (WYEC)tapes for use by the 00E-2 program. A brief description of these weathertapes is included in the Appendices to this section. Only the TMY, TRY, andCTl tapes are included in the 00E-2 library.* The TRY tape library is not available for the IBM version of DOE 2.1A. Tocreate a weather tape for 00E-2.1A Simulation, the user must get a weathertape from NOAA and process it using the IBM version of the weather processor.Ground temperatures and clearness numbers, available from LBL,must then be added.VIl1.2 (Revised 5/81)
