venting appliances that create heat is not done anywhere as far as i know. the refrigerator is the main appliance that needs this because it is essentially a heat pump that runs all the time. insulating it well and venting its hot side is very simple conceptually and is completely doable.

not venting heat generating appliances inside the house is a design flaw and does not follow passive house principles. because nobody addresses this problem, i do consider almost all passive houses to be incorrectly designed and implemented.

the reason why this problem is not addressed is because some degree of cooling capacity is usually present and can keep the house cool despite this flaw. the heat load from the appliances is relatively small and so it is overlooked -- small compared the loads encountered in old-style houses. also, heat generating appliances are a benefit during the winter, so the problem only exists half of the time.

in an ideal system, all heat generated by all systems in and around the house would be channeled and utilized correctly. we are coming closer to that goal.
