[Bldg-sim] Bldg-sim Digest, Vol 60, Issue 21

[Dru.Crawley at bentley.com]

You should read the notes at the bottom of the .stat files:

- **Note that the ASHRAE classification shown here is derived algorithmically from the source weather data.
 -   It may not be indicative of the long term climate for this location.


Use the information in  ASHRAE Standard 169 (or 90.1) to define the climate zone -- from the long-term statistics, not a 'typical' weather file.

When you open one of the weather files (found in EERE website) as text, you can see the information on the ASHRAE climate zone. I don't think there is a bug in eQUEST since the climate zone definition doesn't depend on the software used for the simulation.

However, the description of the climate zone according to this doesn't seem to agree with calculations based on different data. So I am wondering, since I am using the EERE weather file for my eQUEST simulation for LEED, if I have to define the climate zone as found in the file or as calculated. I hope this makes sense and answers your question.

Thanks,

Eleni
