Dr. Caroline Engel Purcell:

I will let Mr. Hoyne take the question about the heat pumps and about calculating when they will be efficient enough. Tasking the one-stop shops might be an avenue by which to do it. Dr. Daly works with the University of Lincoln and with private practice through Carrig Conservation International. The type of work that we are doing in these assessments, which are in situU-value assessments, is generally done through private commissions and publicly procured projects. The study with UCD is separate to that. Another way that one could go about this is by earmarking funding for this particular testing or modelling so that it will be part of retrofit projects going forward. Not every client will commission it or set aside money for it. They would prefer to go with what they feel is best. However, that might push the budget up too high, especially for private homeowners. However, if there was a grant to do the U-value testing and the hygrothermal modelling, that data could then be anonymised and gathered in some sort of centralised library database. That might be a way to go about it. Mr. Hoyne might have more ideas about the one-stop shops.
