Abstract

Gives the conventions that should be followed by numerical modellers to produce consistent, reproducible results. Identifies two key modelling outputs, temperature factor and linear thermal transmittance, for purposes of building regulation. These key outputs should enable designers to confirm the adequacy of particular junction details and help with the development of novel solutions to improve the thermal performance of junctions.
