Climate will clearly play a key role in the performance of any building so it is important to use the appropriate location settings for any analysis. For Apache dynamic simulations in IESVE a simulation weather file is required.
These files contain data for variables including dry bulb & wet bulb temperature, wind speed & direction, solar altitude & azimuth, cloud cover etc for each hour of the year. Weather File SourcesThe standard simulation weather files are sourced from various places and converted into the standard FWT file format.
Usually the fwt will have an abbreviation that points out where the data was acquired (e.g: EWY = Example Weather Year. These are individual weather years sourced from the MET office).
Tm2 Weather File Format Online
Most files are sourced directly from the energy plus website. You can read about different weather sources. The weather file formats the VE can read are.fwt (proprietary format) and.epw files. When you install the Standard Data & Weather Files as part of the IESVE installation the basic set of simulation weather files is included for the locations listed. Additional weather files can be acquired from a multitude of sources (see above) for use in Apache simulations, these will usually be in the format.fwt or.epw. To access these in the IESVE software they should be copied into the weather subfolder of the Standard Data & Weather Files installation (typically C:Program Files (x86)IESShared Content). After this the new files are available to select on the Simulation Weather Data tab of ApLocate.
Tmy3 Csv Data
I believe that in the TMY2 format, columns 2 and 3 of each line containthe year on which that data point was recorded. I am not sure what isdone for TMY2 files that are 'created' instead of containingrecorded data.Kind regards,DavidAt 02:34 7/24/2006, keilholz, werner wrote:Hi Franck,TM2 is only a data format. It depends on what the person who created thefile put into it. Usually, the data are averages over many years.The TM2 files delivered with TRNSYS were created with METEONORM(see)and do not represent 'real years', but 'Typical Mean Years' (that's wherethe names TM2 and TMY come from).The TMY2 users manual is available online.Werner.
