“…At its core, a lifecycle approach suggests that the best available technological solutions and construction practices should be implemented in every step of the renovation activities across the renovation project lifecycle [50,66]. It is widely acknowledged that deep renovation plans are rarely made from a lifecycle perspective [67][68][69]. The opportunistic nature of deep renovation practice results in short-termism both in terms of planning and payback to the detriment of implementation quality, living standards and energy performance [68].…”

The building stock accounts for a significant portion of worldwide energy consumption and greenhouse gas emissions. While the majority of the existing building stock has poor energy performance, deep renovation efforts are stymied by a wide range of human, technological, organisational and external environment factors across the value chain. A key challenge is integrating appropriate human resources, materials, fabrication, information and automation systems and knowledge management in a proper manner to achieve the required outcomes and meet the relevant regulatory standards, while satisfying a wide range of stakeholders with differing, often conflicting, motivations. RINNO is a Horizon 2020 project that aims to deliver a set of processes that, when working together, provide a system, repository, marketplace and enabling workflow process for managing deep renovation projects from inception to implementation. This paper presents a roadmap for an open renovation platform for managing and delivering deep renovation projects for residential buildings based on seven design principles. We illustrate a preliminary stepwise framework for applying the platform across the full-lifecycle of a deep renovation project. Based on this work, RINNO will develop a new open renovation software platform that will be implemented and evaluated at four pilot sites with varying construction, regulatory, market and climate contexts.

“…To foster the sustainability of the renovation process, a new multi-criteria approach [16] aimed at minimizing the environmental, economic, and social impacts of the intervention and of the retrofitted building during the whole Life Cycle should be considered. In this section, an overview of new possible design targets and operative choices for a sustainable and holistic renovation is presented [1].…”

“…As a consequence of the current practice, an upgrade of the sole energy performances may leave the building structurally unsafe; conversely, a structural retrofit, usually carried out in emergency situation, may result in an environmentally unsustainable intervention, despite being fully compliant with the current structural building codes. A new and integrated approach to the building renovation is thus required, and new techniques and solution sets must be conceived to overcome all the deficiencies of the existing buildings, thereby pursuing sustainability, safety, and resilience at the same time [1]. In this scenario, the paper's original contribution relies on the proposal of diagrid exoskeletons as a novel technique to be adopted in the deep integrated renovation of existing RC buildings.…”

“…As far as environmental sustainability is concerned, diagrids may be conceived by addressing the principles of the Life Cycle Thinking (LCT), which are aimed at minimizing the impacts and costs of the intervention and of the retrofitted building along its whole life cycle [9,1]. Accordingly, diagrids may implement recyclable/reusable materials, and reparable, easily maintainable, adaptable and fully demountable elements, thus reducing the impacts along the use phase of the building.…”

“…The actual average European construction rate is only 1.5% [1]; therefore, the sole construction of new high-performance buildings will not entail meeting the targets of the European roadmaps. Sustainability in the construction sector can only be pursued by substantially renovating the existing building stock, which is obsolete, massively energy consuming, and vulnerable to natural and man-induced disasters [2,3]. Two options may thus be envisioned to account for the multiple deficiencies of the existing building stock: demolition and reconstruction, and an integrated deep renovation fostering safety, resilience and sustainability; the latter solution should always be preferred over demolition and reconstruction [4].…”

The holistic renovation of the existing building stock is now recognized as a priority in order to reach the European targets in terms of sustainability, safety, and resilience. Nevertheless, the average European renovation rate of the building stock is only 1.5%. The Building Performance Institute Europe identified as major barriers to the renovation of the existing buildings the need to relocate the inhabitants, the extended downtime required during the construction works, the high cost of the interventions and the lack of adequate business models fostering the renovation. This is particularly true for buildings located in seismic prone areas, which require extensive structural works to be combined with energy upgrading measures. To overcome these barriers, especially those connected to the relocation of the building functions, retrofit solutions carried out from the outside of the building are generally preferred. In this work, design spectra for the preliminary design of elastic seismic retrofit solutions carried out from the outside are derived for reinforced concrete (RC) buildings typical of the post-WWII building stock. A parametric evaluation of the retrofitted structure is conducted considering a simplified 2 DOF system, and a set of design spectra are defined in order to simplify the design procedure and to derive the optimal retrofit parameters. Finally, a reference case study representative of a typical RC building is developed to asses and validate the procedure.
