[Bldg-sim] Sources for Actual Weather Data

James,

Try the EnergyPlus weather service. It's free and convenient but there are
sometimes data gaps:
http://apps1.eere.energy.gov/buildings/energyplus/cfm/weatherdata/weather_re
quest.cfm

I'm not sure if they have weather back to 2003 though. You can also try a
paid service such as the National Climatic Data Center or the Weather Bank
for high quality, validated weather data. 

Good luck,
Hwakong

I finally got around to looking at the nrel.gov link referenced in the post
below and found that it's not actual weather data, but it's TMY3 data.

Does anyone know where to find, for example, the actual, hour-by-hour,
just-the-way-it-really-happened,  weather data for 2003 in Grand Rapids, MI?

Thanks!

I'm modeling an existing building in Trane Trace and have utility data for
the last two years.  I'd like to replace the TMY2 weather data in my

model with actual hourly data.   Can anyone point me to information on 
where to obtain real hourly data in TMY2 format?
