Many thanks for the prompt reply and apologies for not giving sufficient information.
The house I am trying to model has a staircase that connects to the open plan first floor living/kitchen area, which I have constructed with Air Walls. Could this be the problem?
The energy calculations seem to run ok, but the Energy Balance error says ‘1. Not all of the connected heating branches are of the same length or there are more than 8760 values in the list.’. I attach here a screenshot of the error messages.
On the Adaptive Comfort Calculator the error message is “The calculation has been terminated by the user!” and the 3D Chart connected to this component says that “Input parameter _inputData failed to collect data!”. Also attached here screenshots of the error messages.
I hope this is a bit clearer, but please let me know if I need to post more information.
Many thanks again,
