6 1.0 [H]-house Goals Improved Indoor Environment Quality - IEQ Address shortcomings associated with modern airtight buildings > increased relative humidity levels indoors > higher concentration of air pollutants Mould growth Materials emissions Evapora?ons

7 1.0 [H]-house Goals Improved Indoor Environment Quality - IEQ Develop robust solutions that are able to react to reduced air exchange rates and address associated problems > damp problems and condensation, resulting in mould growth > disorders and allergic reactions (worst case) In combination with natural ventilation Importance of material selection Increased moisture buffer through natural building materials
