Building envelope plays a key role in regulating heat and mass transfer between outdoor and indoor environment, being the primary interface between outdoor and indoor environment, building system and occupants. The stringent CO2 emission targets (more than 90% less CO2 emission compared to 1990 levels by 2050) have boosted the development of innovative envelope technologies that are no longer focused only on reducing energy demand and lowering CO2 emissions in buildings during operations, but which are integrating materials and technologies aimed at improving building performance in terms also of
- improving environmental quality (indoor and outdoor),
- promoting and supporting energy flexibility and independence,
- increasing adaptation and mitigation potential for contrasting climate change effects
- reducing whole life CO2 emission.
In parallel to the development and scaling-up of novel building envelope smart functional materials, concepts and systems, key aspects to increase their real world uptake are: a) reduce the complexity and unreliability of their building operations (for simple and more complex model based controls); b) move from an “energy efficiency-centric” to an “occupant-centric” design and operation approach; c) improve the reliability and reduce the complexity in the quantification of their performance at the design stage and during operations.
