Thanks in advance

Not sure if VE calculates it otherwise, but the Cm-value should be calculated as below (though called Km instead).

How is the Km value (effective thermal capacity) calculated for a construction?

The Km values are calculated by:

For each construction element:

Calculate the contribution ...

Hi,

I have two questions that I'd be happy to find answers to.

First, in ApSys, how do I model a system which is heated by district heating and cooled by district cooling, in terms of seasonal efficiency, delivery efficiency, and SCoP for the heating part and seasonal EER, delivery efficiency and ...
