In PM&VL5 building envelope systems will be analysed with respect to the four domains of indoor environmental quality and impact on building occupants so that they can be optimized during the operation phase as well as design or redesign stage considering users’ experience. This process is necessary to improve the mutual behavioural conditions in terms of both energy-saving potential and comfort.

The PM&VL6 supports the development of a holistic approach to implement new energy-efficient and user-centred dry-layered envelope solutions. It focuses specifically on health and safety requirements by offering testing, performance verification, market analysis of existing products, feasibility checks according to the existing regulations and, in case of gaps, can collaborate with SMEs and industries in general in developing a methodology to verify, validate and finally certify new innovative nZEB Envelope Enabler solutions (nEESs)
