Re: [EnergyPlus_Support] weather file





The weather data by request from the EnergyPlus team was a volunteer (unpaid) activity which used Meteonorm -- a program that created weather files by interpolation based on climate data statistics. Because a number of groups now provide weather data for virually any location in the world at a reasonable price, the EnergyPlus team will no longer provide weather files from Meteonorm. The Yahoo Groups site is at capacity.

Two places you can obtain files are: Weather Analytics and Meteonorm:

Weather Analytics
( www.wxaglobal.com ) - Site specific weather files in EnergyPlus format based on the latest 30 years of hourly data are now available from the private sector company Weather Analytics for any official weather station or over 600,000 35-km grid tiles across the globe. These files are built by integrating hourly weather station observations and the new NOAA reanalysis data sets. Both Typical Meteorological Year (TMY) files and individual, Actual Meteorological Year (AMY) files are available as well as files constructed from the previous 12 months.

Meteonorm
( www.meteonorm.com ) - Files for specific locations can be purchased in EnergyPlus format from Meteonorm company. Meteonorm extrapolates hourly data from statistical data for a location. Where statistical data aren't available, Meteonorm interpolates from other nearby sites. Generally a statistical approach is a last resort--weather files generated from statistics will not demonstrate the normal hour-to-hour and day-to-day variability seen in measured data.

Information on selecting weather data appropriate for energy simulation is described in this paper:
