[Equest-users] Thermal mass effects --- of stuff (UNCLASSIFIED)

General question:

Do any energy models take into account the thermal mass of stuff?

Then extreme case I know about is a garage.  When my garage was empty and I turned on the heater it heated up fairly quickly.  When I brought in my truck, tools, shelves, etc. (a few tons of steel) it took a lot lot longer to get warm.

This is an extreme case, but the same thing would happen in every type of building on some level.

Hello Peter,

 

Create layered walls with the materials you intend to simulate and then set the floor weight = 0 to trigger custom weighting factors. You may have to fiddle with the interior convection/radiation coefficient to get a meaningful “connection” to the room air node.

Hello,

 

      Is it possible to model the effects of thermal mass of interior walls? if so, how is that done?
