[Equest-users] Weather

[Katie Tuttle]

Does anyone know where the weather data for eQuest comes from?  Why I ask is because many energy modeling applications have requirements on the type of weather data used for simulation.  What I've noticed is that if you change the "Run Period" in eQuest (see screen shot below as found on the "Project & Site" tab in detailed edit mode under "Simulation Options: Entire Year"), the energy use also changes.  I also found that if you set the run period to span over multiple years, the output (even with units per year) adds all of the years together.  Is eQuest not using a TMY, TMY2 or TMY3 file to create its .BIN files?  If so, why would the year even matter since you usually want to be using typical weather data?  Do those years actually correspond to actual data?

My second question (relating to this) is how to use DOEWth to convert TMY2 files to .BIN files?  Is this the only way to do this?

Thanks,
