Data is based upon CIBSE Guide A, Section 6, for heat emissions from an adult male body.
Data is supplied for a number of fixed points (figures shown in black)
If the room temperature exceeds 26°C then the figures for 26°C are used.
If the room temperature falls between the fixed data points, then the values are interpolated (example interpolation shown in yellow)
The interpolation function uses the following methods:
