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 the following five
Subtask 1: Model and Algorithm Development:
This task includes improving modelling techniques and testing simplified models for predicting the combined
effects of HAM-transport on insulation quality, hygric behaviour and durability.
Subtask 2: Inside and External Environmental Conditions:
This task includes selecting environmental parameters and a methodology of handling them and the development
of exemplary sets of environmental conditions.
Subtask 3: Material and Layer Properties:
This task includes data collecting on thermal hygric and air properties of materials and layers and substantial fresh
measuring work, especially on the moisture and air properties.
Subtask 4: Experimental Verification:
Experimental verification includes hot box and field tests on HAM- transport in envelope parts and comparing
measurement results with model prediction.
Subtask 5: Performances and Practice:
This task Includes the translation of HAM-knowledge in correct design and execution of highly insulated new and
retrofitted envelope parts.
