have learned of some problems with college dormitories of a Passiv Haus building

am wanting to inquire about what the best practices are for unoccupied tight
buildings. Since they are unoccupied, I would hope you could turn the
energy consuming machines off. The humidity sources within the would be
reduced, (breathing, cooking, bathing, et.). Although you would still have
ambient humidity and standing water of toilets. Perhaps it would be a good
practice to drain the toilets. This issue would be more significant in the
Summer of high ambient humidity. I live in the mixed climate of
Virginia. However, I would be interested in comments as it relates to
other climates. </DIV></DIV>

question applies to tight buildings that have active dehumidification (ac or
dehumidifier) and ERV, or no active dehumidification and HRV.
