IEA/Annex 24: Heat, air and moisture transfer
Online version (www.ecbcs.org/Annexes/annex24.htm)
"The objectives of this annex are to model and study the fundamental physical phenomena behind and the consequences of heat, air and moisture transfer through new and retrofitted insulated envelope parts. A special emphasis will be put on the energy quality, depending on air tightness, on the hygric behaviour and on the durability aspects of the construction. The knowledge gained by this analysis will be applied to performance formulation and to checking the design and production of new retrofitted parts. It is divided into five subtasks"
