D4.6: Reports of field implementation at demo cases

Summary

P2Endure is 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 present progress and outcomes of performed renovation activities on the demonstration projects. Important aspects are the recommendations gathered from the stakeholders during the whole renovation process. The project introduces the 4M modular process that will successfully streamline renovation process. The 4M stands for: Mapping, Modelling, Making and Monitoring. Renovation of buildings is a very complex process that involves various stakeholders. Scope of the renovation and the building typology influence the choice of Plug and Play Solutions. The most important lessons learnt from the field implementation of P2ENDURE project at the demonstration buildings: 

• Existing buildings often have old and not updated paper documentations 
• There can be mismatch between 3D laser scanning and developed based on that Building Information Model of the building, what can lead to the problems during installation of Plug and Play façade elements 
• Involvement of the stakeholders: e.g. manufacturer from the beginning in the renovation process, in Mapping or Modelling the latest. 
• Smaller architects’ offices are not used to work with Building Information Modeling and are not aware of the benefits 
• Building Information Model can be a useful repository for all the technical data of the elements and can contain information needed for the energy assessment. 
• Lack of smooth transition from Building Information Model to Building Energy Model (BIM to BEM) 
• Renovation design is still challenging on the buildings under cultural heritage protection due to the very strict rules for approval of the renovation products 
• Slow adaptation of innovative Plug and Play renovation solutions • Lack of open libraries with Plug and Play renovation solutions 
• Contractors are reluctant to work with the solutions that they are not familiar with and with which they do not have experience 
• For public stakeholders the Indoor Environment Quality especially in educational buildings is highly important and they are willing to perform constant monitoring 
• Lack of knowledge on the benefits is hindering the implementation by the end user 
• Low involvement of end-users in the renovation process 
• Lack of manufacturing and mass production of Plug and Play building components
• 
  

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.
