Dryer box and indoor venting – GreenBuildingAdvisor

My opinion is – moisture damage is bad for buildings.

Joking aside, I used to work as an Energy Auditor for an income based weatherization program and it was my job (i.e. I volunteered) to crawl through attics and crawlspaces. Most of the component failures I saw were due to one of two things:

1. Bulk water intrusion

2. Fans that concentrated moisture in areas with moisture sensitive materials (unvented or improperly vented fans being the biggest culprit)

If it was my building, I would do an inspection and try to get some data collected. I would also try the vent the dryers to the outside if at all possible.

Good luck, and have fun!
