D1.4: Design of energy systems at building and district level


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 buildings 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 geoclusters with EU-wide replication potentials. 

Energy systems, meaning plants that have the potential to produce electricity and/or thermal energy directly on site, represents one of the most interesting matters addressed within the P2Endure project. Their potential in terms of PnP or easy mounting, combined to the energy efficiency and the considerable benefits that come from their adoption, suggests that they should be considered in all the case studies, especially within plant configuration where the feeding energy source is, of course, renewable. The present deliverable resolves to report on the application of these kinds of systems within the basket of energy retrofit actions undertaken to some of the P2Endure case studies. As the title suggests, the report focuses specifically on the Design of these energy systems, both at building and district levels. In some cases (e.g. Reggio Emilia case study), analytical results have been already validated through a preliminary monitoring of the benefits. 

This deliverable presents the results of the analyses and investigations for RES solutions and energy grid connection in relevant demonstration cases, as requested by Description of the Action (DoA), investigating in detail some “solutions for RES and energy grid connection”, through their verification and, if possible, implementation, also considering the “specific location and grid availability”. 

Chapter 1 consists of the storytelling of the Deliverable, as a general introduction to the topic. Chapter 2 presents the feasibility studies for relevant demonstration cases, illustrating what demonstration cases have made interventions in terms of “solutions for RES and energy connections” as real actions to meet P2Endure research targets especially in energy saving. For these interventions, energetic analyses are performed, reporting on actions at both building and district level. Building Integrated Photovoltaic Systems (BIPV) are the most preferred technology. Outputs of this first section are short recaps on the design approach and the benefits for the most valuable actions. For any of the selected actions a status of the art of the proposed solution is given. Chapter 3 provides economic and financial analyses, together with a preliminary business plan of the most valuable actions, while chapter 4 gives a final recap of the presented actions, presenting findings as the lesson learned from this research branch.​
