1. Where G is 1800 mm or more, the cooling shading multiplier is to be taken as 1.0.
2. The cooling shading multiplier for P/H values between those shown in Table J2.4d can be
interpolated.
3. For glazing in the internal fabric use the appropriate value for the south orientation sector
with a P/H value of 2.0.
