Hi all,
We are all trying to move towards electrification, so electric heating, logically will be heat pumps in one form or another. This credit is currently based entirely on the quantity of (and type of) refrigerant relative to the amount of cooling it provides, no consideration of heating.
I am building a naturally ventilated, passively cooled building, with heat from a central heat pump for the winter. The Q value in the impact equation is tiny, as we are only actively cooling one little electrical room. But we are providing heat from that refrigerant, it is a central plant of sorts so it is doing a lot of work with a relatively small amount of refrigerant, are we just excluding all buildings like this from this credit?
I realise it is only one point, but it doesn't seem logical.
Cheers
