[Description]
This DVD contains the results from ASHRAE Research Project RP-1477, "Development
of 3012 Typical Year Weather Files for International Locations," developed by
White Box Technologies, Moraga, California, Y. Joe Huang, Principal
Investigator. The DVD contains "typical" weather files, suitable for use with
building energy simulation programs, for 3012 locations outside the USA and
Canada. The files are derived from Integrated Surface Hourly (ISH) weather data
originally archived at the National Climatic Data Center. For these selected
locations, the ISH database contains weather observations on average at least
four times per day of wind speed and direction, sky cover, visibility, ceiling
height, dry-bulb temperature, dew-point temperature, atmospheric pressure,
liquid precipitation, and present weather for at least 12 years of record up to
25 years. Because the ISH database contains no measured solar radiation, the
hourly total horizontal solar radiation is calculated using an empirical model
based on the sun-earth geometry, reported cloud cover, temperature difference
from three hours previously, relative humidity, and wind speed. A second
empirical model is used to calculate the direct normal solar radiation based on
the solar angle and the ratio of the derived total global horizontal compared to
the extraterrestrial solar radiation. Other models then use these derived solar
radiation values to calculate various illuminances (global horizontal, direct
normal, diffuse horizontal) and zenith luminance that are useful for daylighting
studies.
