D3.4: Validation report of replicability and scalability of PnP prefab solutions​

Summary

P2Endure is a European research project funded under the EU programme H2020-EE-2016-PPP (supporting accelerated and cost-effective deep renovation of buildings through Public-Private Partnerships (EEB PPP). The project aims to improve the availability and performance of energy saving solutions for deep renovation and transformation of vacant, obsolete or sub-optimal public buildings into dwellings promoting evidence-based innovative solutions for deep renovation based on prefabricated Plug and- Play systems in combination with on-site robotic 3D-printing and BIM demonstrated and monitored at 11 real projects, 2 virtual demonstrators in 4 geo-clusters with EU-wide replication potentials.

The main purpose of this document is to assess the replication potential of P2ENDURE solutions to other buildings that are located in different European countries. For each of the demonstration building, similar buildings that can be treated as the followers are detected. The buildings are categorized into main typologies, functions and energy performance before renovation. Important aspect for selection of a certain solution is the climatic conditions in which building is located. For example the need for heating, cooling or insulation strongly depends on the building location and temperatures in the region. The idea is to support potential investors and designers and to show them what are the technical, legal, financial and social constraints when applying the P2ENDURE solutions. 

The implementation of a PnP façade solution is more effective on the buildings with modular and regular building geometry, regular windows openings and details. Therefore especially residential buildings constructed with industrialised prefabricated method constructed between years 1971-1985 are suitable for such solutions. 3D printing technology is highly relevant for the buildings that have façade ornaments and their original façade appearance needs to be preserved. Solutions that can be applied widely are 3D scanning, based on which as-built Building Information Model can be performed or Comfort EYE that is a tool developed in the project for indoor air quality monitoring. It is estimated that for this moment (taking into account number of already insulated buildings and safety reduction factor that indicates that only part of the buildings may be suitable for P2ENDURE renovation) following number of residential buildings is pointed: 794 282 buildings in Poland, 549 200 in the Netherlands, 664 209 in Norway, 4 930 000 in Germany and 1 139 549 in Italy. In addition, it is estimated that approximately 526 educational buildings in Warsaw and Gdynia, the P2ENDURE solutions can be implemented in a short timeframe (i.e. within 3 years). The target group of this document is a wide range of stakeholders composed from the public and private building owners, city administration professionals, designers and architects.
