Which dataset should you use?
The Ladybug Tools EPW map aggregates weather files from many sources and makes them spatially explicit. You can search for a location by typing it in the search field, and the map will zoom to your selected area. However, a single place can have multiple weather files, so how does one decide which file to use?
Well, it depends on the type of study you need to complete. Suppose you are studying the impact of climate change and global warming on energy consumption in buildings. In that case, you may want the newest data that captures increases in global temperatures over time. However, if you’re going to simulate daylight, you should choose a climate file that closely resembles your site’s microclimate.
