About meteorological data for the cooling load calculation according to ASHRAE

Explains the concept of meteorological data in conjunction with the dynamic cooling load calculation based on ASHRAE.

Depending on the selected calculation method, you can select or download the meteorological data for your project directly from a list, free of charge. You can change the designation of the project site for the printout and alter the meteorological data to local conditions if need be.

Meteorological data for ASHRAE

The meteorological data for the calculation according to ASHRAE are based on the Cooling Design Day, which is simulated continuously for the design day until no more room temperature changes take place and the temperatures are stabilized. You can also create a design day manually.

Supported formats

In the cooling load calculation according to ASHRAE, you need meteorological data with the file endings *.epw and *.stat. You will receive these files on downloading the meteorological data at http://https://energyplus.net/weather.
