Dr. Ciaran Byrne:

We can look at that but the other piece, which is possibly even more confusing - Dr. Keilthy might want to comment on this – is the issue of under-heating. We see people in energy poverty whose BER might be fine or might look great nominally, but they still cannot afford to heat the house. Then we have overheating or the compensatory effect. If people have a home that is cold and they get it retrofitted, they can now use three rooms instead of two. There is other, side-bar stuff at play but we can certainly have a look and come back with some estimates.
