My experience is in the initiation, coordination and execution of national and international (EU, IEA) research projects and associated standardisation activities (CEN, ISO) in the field of energy consumption and indoor climate in residential and office buildings (energy and comfort).

Also special interest in passive solar energy and thermal-optical properties of windows, solar shading systems and facades and in particular on energy performance and the relation with building regulations, nationally and internationally.

Examples:

Leader of European projects such as: IEA ECBCS Annex 12, EU WIS, EU REVIS, EU WinDat,  EU CENSE.

Key roles in European and IEA projects such as: EU PASLINK, EU ENPER, IEA SHC Tasks 10, 18, 27, EU Buildings Platform.

Co-convenor of ISO/TC 163/WG 4 (joint WG with TC 205) on energy performance of buildings using the holistic approach.

Active in national (NEN) and international (CEN, ISO) standardization committees on energy performance and on thermal and solar properties of facades and windows.
