Abstract: 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.

​Ninety 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) technologies supported by Building Information Modelling (BIM) to provide affordable, interchangeable and quick-installation solutions to overcome the main barriers of building deep renovation​.

​​Hoe kan ketensamenwerking zorgen voor een toename in het aanbrengen van klimaatadaptaties aan woningen van woningcorporaties in Nederland? Promovendus Martin Roders gaf op 18 juni aan de TU Delft een toelichting op zijn dissertatie Partnering for climate change adaptations by Dutch housing associations. Opmerkelijk genoeg leidt ketensamenwerking niet automatisch tot meer innovatie en klimaatadaptie, is één van de conclusies.​

Energy efficiency and reduction of carbon emission of Healthcare buildings and districts are a key factor for a sustainable community since their energy use and carbon emission are among the highest of all building types. A hospital – which is a part of a healthcare district – uses 2.5 times more energy than an office in average. In order to cope with the energy, financial, political, societal and environmental crises, all healthcare districts in Europe are urgently seeking to substantially reduce their energy consumption and carbon emission by 30–50%. For this purpose, the design phase of new building projects as well as building retrofitting projects is the crucial moment for integrating multi-scale EeB solutions. At present and in the near future, clients, architects, technical designers, contractors, and end-users really need a breakthrough in designing energy-efficiency buildings integrated in the healthcare districts. STREAMER is an actual EU FP7 industry-driven collaborative research project on Energy-efficient Buildings (EeB) with cases of mixed-use healthcare districts. The research aims at 50% reduction of the energy use and carbon emission of new and retrofitted buildings in healthcare districts by optimising Semantics-driven Design methodologies with interoperable tools for Geo and Building Information Modelling (Semantic BIM and GIS) to validate the energy performance during the design stage. This paper presents the methodology defined within STREAMER to approach the organizational, distribution and functional aspects of Healthcare buildings in relation to their energy-related features. The typological, technical, distribution and functional characteristics of each building type is investigated and connected to the functional aggregative configurations based on the proximity and the interdependencies between spaces and functions in order to define a compatibility matrix between various building typologies and their energy-related features and characteristics.​

Purpose ‐ This paper aims to introduce a method of performance-based procurement, based on the most economically advantageous tender (MEAT), for low-disturbance bridge construction projects in urban environment. Design/methodology/approach ‐ The first part of this paper reviews the key performance indicators (KPIs) of low-disturbance construction and the procurement procedure based on the MEAT principles. The second part reflects on two actual bridge projects (the Rotebro bridge in Sweden and the Arno river bridge in Italy) as observatory case studies to analyse how clients and contractors can implement the KPIs in MEAT. Findings ‐ The research findings demonstrate the possible inclusion of the KPIs of low-disturbance construction into the MEAT criteria. The MEAT principles can then be used in combination with either a traditional or an integrated procurement strategy. Research limitations/implications ‐ The implementation of MEAT to achieve low-disturbance construction projects is considerably new and still requires an empirical validation. A further elaboration of the procurement strategy within the EU regulatory framework is strongly recommended in order to assure the broader impacts of sustainable construction. Practical implications ‐ The findings and recommendations support the practical development and the use of MEAT in construction projects in the EU. Originality/value ‐ This paper presents on-going investigation within the FP7 collaborative research project "PANTURA", which addresses the actual research agenda of the European Commission on low-disturbance and urban-friendly civil infrastructure projects.​

European countries are currently facing serious problems with the quality of their high rise housing stock. The majority of the high-rise housing stock was built in the first decades after World War II, and cannot meet the current standard in terms of technical and social quality. The need for refurbishment of these buildings and their environment is an urgent problem, but has not been adequately solved by the local government. There is still a need for a well-organised governance system at city, district and neighbourhood level that is able to initiate and facilitate the refurbishment programme. An MSc graduation research project at the Eindhoven University of Technology on a pilot project in the Slovak Republic has shown that the effective implementation of new technical solutions for refurbishment is failed due to financial and organisational barriers. On the one hand, as home-owners or inhabitants are facing increasing costs for services (heat, gas and electricity) and maintenance, many of them are not able to take part in financial investments for major refurbishment. On the other hand, the intention of the European Union and different national governments to address the issue of sustainable regeneration often fails to reach the individual home-owners or inhabitants. After describing the current situation and problems, this paper moves on to propose a new systematic approach for policy development. Based on an ongoing research project at TNO (Netherlands Organisation for Applied Scientific Research), conceptual process models are presented.
