Hey Ed, Can You Please Comment on Things in a House That Are Intermittent Loads Like Dryer Bathroom Fans?

In this edition of "Hey Ed," Ed talks about intermittent loads like dryer bathroom fans.

Hey Ed, can you please comment on things in a house that are intermittent loads like dryer bathroom fans? There are loads that are figured in to a heat loss or heat gain calculation that are constant. There are loads that are intermittent and the big difference between those two is if it’s constant, we count it. If it’s intermittent, something that runs intermittently like a dryer. When it exhausts air, it increases the heat loss or heat gain. Same way a bathroom fan or a vent hood in a kitchen would. They are intermittent loads and because they run intermittently, they are not counted as part of our heat loss or heat gain calculation. And that’s the way I see it.
