More stringent weather data?
More stringent weather data?
(OP)
While performing an energy simulation, a question came up by the owner about what weather data set I was using and why. I was using the weather data set found here:
http://www.nrel.gov/rredc/solar_data.html
but was asked why I did not use the set found here:
http://www.ncdc.noaa.gov/oa/ncdc.html
My response was that I needed weather data for each hour/day/month of the year, which only NREL provided, and since it was a subsidiary of the DOE I believed that it validated the data set.
However, he had never heard of the NREL and had only heard of the NCDC, so I was directed to use NCDC if possible. He believed the NCDC to be more 'stringent'. Unfortunately, from what I can tell, NCDC only publishes daily weather data and does not publish hourly weather data, which is unusable.
I would use ASHRAE weather data but I don't think ASHRAE provides hourly data either.
I am also using HAP 4.3, but my particular application is not modeled by HAP.
What weather data set should I be using? Which one is the most commonly accepted?
