In the residential sector, solar thermal and PV systems are typically placed on building roofs with limited attempts to incorporate them into the building envelope thus creating aesthetic drawbacks and space availability problems. On the contrary, the use of facades is highly unexplored, and daylight control is delegated to individual management of blinds and curtains leading to high thermal loads during mid-seasons and summer. 

In the tertiary segment (offices, schools, hospitals), the roof is again, most of the time, the only surface devoted to the installation of solar thermal and PV technologies. While daylight control here is state of the art in terms of shading effect, the utilization of shading devices to redirect natural light into the room thus improving visual comfort still needs further work.

When energy efficient technologies are installed together with traditional ones, frequently they are just “added on top” of the main systems, resulting in high investment costs and lowperformance optimization. An interesting option to overcome this competition is to combine multiple functions in envelope components thus enabling hybrid systems to simultaneously cover different energy, comfort and aesthetic needs.

This report is a result of extensive discussions within Task 56 of the Solar Heating and Cooling Programme (SHC) of the International Energy Agency (IEA). Innovative solar envelope technologies face multiple barriers, which prevent some of these innovations from contributing significantly against climate change. This report presents the barriers that the experts of Task 56 are aware of. The aim is to provide a comprehensive view (as much as possible) that developers of new integrated solar envelope systems could benefit of, at an early stage of their planning phase.
