[esp-r] Re: furniture in esp-r

Hi Achim,

we planned to do some experiments to see how things should be taken into
account, what the influence is on all modes of heat transfer for a range of
potential settings.
It seemed usefull to first check how popular building simulation codes
handle the issue.
So, I will take the explanation below and I assume it can be coupled to the
adaptive convection algorithm.

What I mean by loading and unloading is that the volume, representing the
furniture, has to take part in convection and radiation (and potentially
some conduction) in order to exchange heat and thus influence its thermal
state.
