Window area
National Calculation Methodology (NCM) modelling guide (for buildings other than dwellings in England) 2013 edition, published by the Department for Communities and Local Government (DCLG), defines ‘window area’ as the: ‘Area of the structural opening in the wall/roof; the area therefore includes the area of glass + frame.’
NB Percentage glazing is based on the area of wall seen from inside the zone looking out, and therefore excludes the wall area taken up by floor/ceiling voids, floor slabs etc.
