HVAC Gas boiler with single room cooling

robbraid · Posts: 2

Hello
I have now downloaded the latest version of DB v.076.
I am working on an EPC for a 1980's office block which uses gas 'combi' boilers for heating and DHW. The building also utilises a number of recently added split systems to provide cooling to a number of individual rooms. I am attempting to enter this specification into the model.
I read somewhere that BRE guidance for entering the cooling system into SBEM is as a split system, heat pump/air source, fuel type: gas. Is this correct? The split units are only being utilised to provide cooling from grid electric and are operated independent from the building gas heating boiler.
With the split fuel type set at gas the AR is very close to a new build rating..
Thanks any advice welcome.

Did you have any joy with this, I am having the same problem.

I have seen the note on DB about using the splits etc with gas as fuel. If that is the case what do you put for the controls, as the LTHW system and splits are completely independant and are not linked in anyway?

This type of zone set up must occur all the time.
