Plug-and-Play Solutions for Energy-Efficiency Deep Renovation of European Building Stock

none7siNinety percent of the existing building stock in Europe was built before 1990. These buildings are in urgent need for a significant improvement of energy-efficiency through renovation. State-of-the-art renovation solutions are available, but costly and lengthy renovation processes and incomprehensible technical complexities hinder the achievement of a wide impact at a European scale. This paper presents a research on Plug-and-Play (PnP) echnologies supported by Building Information Modelling (BIM) to provide affordable, interchangeable and quick-installation solutions to overcome the main barriers of building deep renovation.openSebastian, Rizal; Gralka, Anna; Olivadese, Rosamaria; Arnesano, Marco; Revel, Gian Marco; Hartmann, Timo; Gutsche, ChristophSebastian, Rizal; Gralka, Anna; Olivadese, Rosamaria; Arnesano, Marco; Revel, Gian Marco; Hartmann, Timo; Gutsche, Christop

IEQ measurement and assessment tools for Plug-and-Play deep renovation in buildings

This paper presents the approach developed for the monitoring and assessment of Indoor Environmental Quality (IEQ) in the whole deep renovation process aimed at reducing energy consumptions and improving comfort. The research was performed by the P2Endure project, that aims to provide scalable, adaptable and ready-to-implement prefabricated Plug-and-Play systems for deep renovation of building envelopes and technical systems. The idea is to use IEQ as one of the design criteria supporting the decision-making process, included into the holistic renovation process developed by P2Endure and called “4M: Mapping-Modelling- Making-Monitoring”. For this reason, a set of Key Performance Indicators (KPI) was selected, with the consequent measurement and calculation methodologies. The KPIs are collected and showed together with the analysis of the different IEQ dimensions (thermal and indoor air quality). The data collection has been investigated extensively, taking into account all possible data sources, measurements and surveys (e.g. special questionnaires for children in schools). In addition to traditional devices, the innovative Comfort Eye sensor is used in the proposed framework. This is a low-cost sensing system capable of measuring thermal comfort together with IAQ, applicable for permanent or periodic monitoring and with low disturbance for inhabitants. The overall procedure is presented, also in relation with the deep renovation process. Then, the application of the measurement and assessment tools in real demonstration cases is illustrated with initial results from the monitoring campaign

Technical, Financial, and Social Barriers and Challenges in Deep Building Renovation: Integration of Lessons Learned from the H2020 Cluster Projects

With a low rate of new building construction and an insufficient rate of existing building renovation, there is the need to step up the pace of building renovation with ambitious performance targets to achieve European Union (EU) climate change policies for 2050. However, innovative technologies, including, but not limiting to, plug and play (PnP) prefabricated facades, information and communications technology (ICT)-support for building management systems (BMS), the integration of renewable energy systems (RES), building information model (BIM) and building performance simulation models (BPSM), advanced heating, ventilation, and air conditioning (HVAC), advanced geomatics, 3D-printing, and smart connectors, cannot alone solve the problem of low renovation rates of existing buildings in Europe that is hindering reaching of EU-wide targets. A workshop was held at the Sustainable Place Conference 2018 to present, with an integrative approach, the experiences from four H2020 innovation actions, i.e., 4RinEU, P2ENDURE, Pro-GET-OnE, and MORE-CONNECT, which were united by their central aims of improving building energy performance through deep renovation practices. This article presents the outcomes of the joint workshop and interactive discussion, by focusing on technical, financial, and social added values, barriers and challenges, in the context of the building renovation processes tackled by the four projects. Conclusive remarks converge on the identification of open questions to address future innovation opportunities, as well as some recommendations to be used at a policy level and/or in future implementation projects

Plug-and-Play product, process and sensing innovation for Energy-efficient building deep renovation

This paper presents the activities performed by the P2Endure project that aims to provide scalable, adaptable and ready-to-implement prefabricated Plug-and-Play (PnP) systems for deep renovation of building envelopes and technical systems. These innovative solutions are applicable to transform non-functioning or sub-optimal public and historic buildings into dwellings and are applicable for the widest range of building typologies, i.e. public buildings, residential buildings, and transformation projects. The main innovation of P2Endure comprises PnP prefab systems enabled by 3D printing, innovative sensing technologies such as laser scanning, thermal scanning and the Comfort Eye (an innovative IEQ scanning device), also integrated with BIM. P2Endure presents a proof-of-performance of the optimised PnP renovation techniques by implementing 10 large-scale and live demonstration projects that represent the main deep renovation typologies and real market demand in 4 EU geo-clusters. This will be done through progressive steps known as “4M: Mapping-Modelling-Making-Monitoring”. The innovative process, tools and solutions are presented together with the initial application to two real demonstration cases: the prefabricated PnP façade designed for the renovation of a nursery in Warsaw (PL) and the design of a PnP HVAC system for residential buildings to be applied in Breda (NL). The design concepts and predicted performance are included to assess the impact of the proposed solutions
