With the goal of making structures more well sealed and a desire to know where our "makeup air" is coming from we are doing more amazing air sealing and adding tech, like HRVs and ERVs, to supply tempered & filtered air to these hermetically sealed spaces ... BUT, we're still installing high power bath fans (some that run 24/7) to ventilate not only the bathroom but sometimes the "whole house".
Is this the best we can do?
Is simply connecting a leg of the HRV to the bathroom the answer? Does it move enough air, is that what it was designed to do?
What are you guys and gals doing in the field (most specifically in retrofits) to address ventilation in client homes, evacuate warm moist air in a bathroom, especially in combustion homes where depressurization is an issue?
What do you do for Range hoods?
What about clothes dryers? We're exploring the possibility of condensing dryers in our weatherization program.
What about an installed (in wall) dehumidifier in the bathroom to replace a fan? Anybody try this yet? Would it be enough to keep the mirror clear?
Thanks for reading and let me know your thoughts.
