Using the H1 calculation method | BRANZ Build
The heat loss of each part of the building is calculated as: heat loss = area/R-value. So for a roof with an area of 140 m 2 and an R-value of R3.0, the heat loss is 140/3.0 = 46.7 Watts per °C. The R-value is for the component, not for the insulation product. You can use the BRANZ House insulation guide to work out the component R-value.
