Dr Susan Roaf's own house,
which uses NorDan windows and doors, is promoted as one of the lowest
energy-consuming homes in Britain. Her recent book: Ecohouse:
a design guide (available from Amazon.co.uk) details the house
as a case-study guiding the reader through ideas for energy efficient
design
or 'eco
design'.
High insulation, high performance
‘It’s no use putting huge amounts of insulation into a wall unless
you’ve got windows of an equivalent insulation or U-value. This house could
not have such an incredible stable internal environment unless every piece of
the outer envelope of the building had the same sort of performance. I’ve
got really great walls in this building but, unless I have NorDan windows, I
could never achieve that equivalent.’
