Has The Reseach Really Not Been Done?

I read in a recent edition of Building 4 Change (don't you just hate the trendy marketing use of a numeral instead of good old fashioned word?) that BRE is about to embark on a study of solid wall properties to assess heat loss before and after insulation, and the behaviour of occupants. Has this research really not been done? Have thousands of homes been insulated under CESP without a reasonable understanding of the heat loss reduction expected? Or did DECC have a pot of money it didn't know what to do with?
