It's reasonable, but some of the U values are wrong and need to be
updated from the building regulations figures. Although these might
have been altered to help meet Kyoto commitments of course..... I

You can do it on a spreadsheet (or paper and calculator, abacus or

Don't forget that the calculations for ground floors taking account of
perimeter use a table of fiddled U values, so a spreadsheet would need
some work unless there is a formula that can be used instead.
