“…Requirements for heat loss of building envelope vary depending on the requirements for indoor climate and energy performance in the specific country, outdoor climate, availability of renewable energy, and building typology [44]. Furthermore, results show that simple thermal insulation of building insulation can ensure a 50% reduction of building heat consumption, while practical measurements have shown a significant increase of indoor air relative humidity and CO 2 concretion levels [45].…”

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.

“…Going forward, MORE-CONNECT focused on significant improvement of pre-production and production process of the developed solutions to advance the overall production efficiency and reduce the production costs [18]. The main tools to achieve this goal include automated 3D scanning of buildings, fully digitalized pre-production process and IT-supported the creation of data describing the automated fabrication of the modules.…”

With a low rate of new building construction and insufficient rate of existing building renovation, there is the need for stepping up the pace of building renovation with ambitious performance targets to achieve EU climate change policies. However, effective technologies alone cannot solve the low renovation rate of existing buildings in Europe that is hindering the reaching of EU-wide targets. A workshop was held at the Sustainable Place Conference 2018 to present successful experiences with an integrative approach from H2020 innovation actions (4RinEU, P2ENDURE, Pro-GET-OnE, MORE-CONNECT) aiming at improving building energy performance through deep renovation. This article presents the outcomes of the joint workshop and interactive discussion, by focusing on the different technical, financial and social added values, barriers and challenges in building renovation as well as on the identification of open questions to address future innovation opportunities.

“…Industrialization will allow the integration of individual components and systems previously manufactured with high quality standards in controlled environments. This significantly increases the speed of construction, leading to a reduction in execution time [34] and construction costs [35]. According to several studies, the use of modular strategies in construction can achieve time savings of 30 to 50% and ultimately cost savings of 20 to 40% [36].…”

“…The passive impact of this system in the building was further analyzed by Garay et al [49], reaching a reduction of the heat loss coefficient in the range of 55%. In addition, Hejtmánek et al presented a deep renovation study consisting of prefabricated insulating panels, implementation new smart HVAC systems and use of renewable energy sources [34].…”

Plug and Play Modular Façade Construction System for Renovation for Residential Buildings

et al. 2021

The present paper focuses on the architectural and constructional features required to ensure that building envelope renovation are safe, functional, and adaptable to the building stock, with particular focus on “plug and play” modular facade construction systems. It presents the design of one such system and how it addresses these issues. The outcome of early-stage functional test with a full-scale mock-up system, as well as its applicability to a real construction project is presented. It is found crucial to obtain high quality information about the status of the existing façade with the use of modern technologies such as topographic surveys or 3D scans and point cloud. Detailed design processes are required to ensure the compatibility of manufacture and installation tolerances, along with anchor systems that deliver flexibility for adjustment, and construction processes adapting standard installation methods to the architectural particularities of each case that may hinder its use or require some modification in each situation. This prefabricated plug and play modular system has been tested by reproducing the holistic methodology and new technologies in the market by means of real demonstrators. When compared to more conventional construction methods, this system achieves savings in a real case of 50% (time), 30% (materials) and 25% (waste), thus achieving significant economic savings.
