Off-Site Plug-and-Play Prefab Systems

Current building renovation processes are time consuming, expensive and often unattractive to owners due to disturbance. The need for lowering renovation time and cost can be readily achieved via off-site prefabrication. Furthermore, since the envelope is the main interface between buildings’ occupants and the outside, it is important to regulate energy gains and losses across it. Low cost, low weight, environmentally friendly insulation, compliant with local fire and structural regulations in the form of prefabricated opaque panels and/or Insulating Glass Units can be used for fast and reliable renovation. Limitations of the existing systems could be overcome by switching from ‘static’ to ‘responsive’ and ‘dynamic’ systems. 

Hybrid “Plug-and-play” prefabricated envelop systems, that not only regulate energy gains and losses across the envelop but also actively interface with the building, integrating renewable energy production systems and storage technologies. They can ensure NZEB status after renovation and take into account occupant comfort requirements. They can be either opaque or transparent (glazing) systems such as windows, glass facades and glass roof elements.

The five projects that take part in the workshop develop such hybrid Plug-and-Play systems. They come together to exchange experiences and map the technological challenges for the adoption of the developed technologies. The Workshop is structured around three topics: a) Overview of the technological developments achieved in each project; b) based on the project developments group active-passive-hybrid technologies in terms of their technical characteristics; c) use the technology mapping to assess the technology potential to contribute towards NZEB and positive energy targets.
