Diversity schedules for residential exhaust

I am failing (dismally) to find any reference information regarding how residential exhaust varies through the day. Ideally, I'd like a separate schedule for toilet exhaust and kitchen exhaust.

Failing to find third party and research-based information, I'd love to compare my personal estimate with yours.

Thanks in advance for any assistance.

We haven't found much good data on this. ResStock currently samples from the Range/oven schedule for probability of kitchen exhaust timing (1 hr per day), and samples from the Shower schedule (I think) for probability of bathroom exhaust (1 hr per day). See https://www.nrel.gov/docs/fy14osti/60... and https://www.energy.gov/eere/buildings... for these schedules.

The Pecan St. Dataport dataset has measured bath and kitchen vent fan power. We plan on examining that to derive schedules in the future. Let us know if you find anything else!
