Hello.
Would someone please define "rain event"?
Is it the total rain since the beginning to the stop of a rain?

Hi Noriko,
Rainfall event within LEED usually refers to a percentile rainfall event which can be calculated using daily rainfall data (obtained from any number of sources for the past five years) and the methodology in the United States Environmental Protection Agency's Technical Guidance on Implementing the Stormwater Runoff Requirements for Federal Projects under Section 438 of the Energy Independence and Security Act.
Hope that helps!
