“…The concern for seismic risk and its differentiated distribution in the territorial and urban context creates asymmetries in the map of spatial and temporal disadvantages, respectively, due to the different conformations of the built heritage and to the diversified perception of risk by residents and administration [52][53][54][55][56]. Similarly, the energy issue, especially in the background of its double dimensions-the general one, concerning the reduction of the climate change effects, and the specific one, the issue of the energy-building poverty-creates further aspects of urban imbalance, triggering filtering down processes in the disadvantaged districts [57][58][59][60][61][62][63][64][65].…”

The research deals with the issue of the seismic and energy retrofit of historic building fabrics having as reference a historic district of Syracuse (Italy). The prospect of the ecological transition on the one hand and the public support funding on the other claim for a valuation programming approach implying the creation of multiple scenarios, each of which is inspired by a different and complementary degree of “saliency and urgency”. These two dimensions of “being worth” by a building aggregation having an its own shape and belonging to a larger and more complex urban system need to be addressed according to some axiological reference, in this case, the concerns of the efficiency and fairness of public spending. This experience concerns the creation of a value-based programming pattern of the seismic–energy retrofit process framed in a Building Information Modelling (BIM) environment aimed at identifying the best intervention strategy among the several ones that can be generated in the logic of the parametric design. Both seismic and energy retrofit expected performances, in fact, can be scaled, complementing the extension and intensity of the interventions. This experiment takes advantage of the BIM multidimensional logic in line with the multiple scales and purposes implied by the relationships between individual/communal axiological profiles and present/future prospects. The experiment consists of the creation of an additive cost-oriented design platform based on which the different and progressive combinations of intensity and extension of the interventions can be compared and selected.

“…Ecosism s.r.l. recently introduced an integrated and low-invasive solution developed in collaboration with the University of Padua [18][19][20] that consists of the creation of a new external envelope represented by RC wall cast in situ between one or two prefabricated layers of insulating material. This outer envelope skin is designed to carry the whole seismic action.…”

Multidisciplinary Performance Assessment of an Eco-Sustainable RC-Framed Skin for the Integrated Upgrading of Existing Buildings

Recent earthquakes have highlighted a general inadequacy of the existing building stock in Italy and the need to address this critical issue by increasing its structural resilience. At the same time, the problem of energy consumption in existing residential and commercial buildings is increasingly significant and incompatible with the environmental targets set by governments. Considering all the aforementioned aspects, the seismic upgrading of existing buildings, based on the use of an eco-friendly and sustainable technology, has become more and more relevant and different intervention approaches have been developed. This paper aims to provide a multidisciplinary approach for the performance assessment of an eco-friendly and sustainable RC-framed skin for integrated refurbishment of existing buildings. A preliminary description of such skin technology is provided with particular attention to the simultaneous improvement of structural (e.g., seismic) and non-structural (e.g., energy, acoustic) performances and to issues concerning the limitation of invasiveness and interruption of use of the building. Technological details and in situ installation phases are described with special regard to connection and interaction with the existing building. Procedures for the assessment of upgraded building performances, in terms of seismic capacity and thermo-hygrometric and acoustic performances, are defined and applied to a selected basic cell structure. The feasibility and sustainability of the proposed upgrading intervention is finally investigated by means of a holistic Life Cycle Assessment for environmental impact and Life Cycle Cost for an economic evaluation. Finally, results from a multidisciplinary performance assessment are critically discussed by relating the performance aspects to the technological and installation issues.

“…Another integrated and low-disruptive solution is the "Geniale cappotto sismico", recently introduced in the Italian building market by the company Ecosism S.r.l. [21,22]. This innovative system consists of adding to the existing building envelope a new earthquake-resistant skin, made up of a thin RC slab cast in situ between two or one pre-assembled layers of insulation materials.…”

Energy, Seismic, and Architectural Renovation of RC Framed Buildings with Prefabricated Timber Panels

et al. 2020

In seismic European countries most of the residential building stock is highly energy-intensive and earthquake-prone because it was built before the enforcement of the most recent energy and seismic codes. Furthermore, this stock often shows a low architectural quality due to poor maintenance and/or construction and design deficiencies: for all these reasons, it needs deep renovation, but the use of common energy and seismic upgrading techniques is often unsustainable in terms of costs, work duration, and occupants’ disturbance. Therefore, new integrated, affordable, fast, and low-disruptive renovation actions are strongly needed. This study proposes an innovative energy, seismic, and architectural renovation solution for reinforced concrete (RC) framed buildings, based on the addition of cross-laminated timber (CLT) panels to the outer walls, in combination with wooden-framed panels. The two panels integrate insulation and cladding materials in order to improve the energy performance and the architectural image of the renovated building. Moreover, the CLT panels are connected to the existing RC frame through innovative seismic energy dissipation devices. In case of an earthquake, these devices in combination with the CLT panels reduce the drift demand of the building, preventing or reducing structural damages and consequent repair costs. In particular, this paper investigates the technical feasibility, the energy efficiency, and the architectural enhancement of the proposed retrofitting system. To this purpose, dynamic thermal simulations were conducted on a typical multi-story residential building from the 1960s, located in Catania, Italy. The results indicated that this retrofitting technique considerably improved the energy performance of the selected building, with a reduction of the global energy demand up to nearly 60%. The presented study is part of a larger research project aimed at also investigating, in a further stage, the seismic performance achievable by the above-mentioned renovation solution.
