This paper presents a literature review about aerogel-based products for building, focusing on the plasters used within the architectural restoration sector. Aerogel has entered the construction field in the last two decades as a component of many insulation products, due to its high thermal performance. Aerogel-based plasters allow the matching of high thermal performance and limited thickness. This makes them suitable when retrofitting an existing building and also when restoring a heritage building. We analyze the results of recent research, focusing on the most commonly used methods for assessing the thermal performances and durability of aerogel-based plasters. As a result of this review, we propose a guideline for manufacturing samples destined for laboratory tests.

The paper discusses how a Geographic Information System (GIS) contributes to set up a Conservation Management Plan (CMP) for the sustainable preservation of a 20th-century architectural masterpiece. The National Art Schools of Cuba are presented as a case study. The complex consists of five iconic buildings built in the early 1960s within a 56-hectare city-park. Since they are today underused and in a poor state of conservation, a research project among Italy, Cuba, and the US addressed a CMP’s preparation between 2018 and 2020. A GIS was prepared to collect and manage the whole data, based on graphic support consistent with both the site’s features and the research’s goal, to set up a comprehensive Conservation Management Plan. By illustrating this experience’s pros and cons, the paper discusses how GIS may contribute to the conservation and sustainable management of such extensive 20th-century architectural complexes.

Purpose: The purpose of this paper is to describe the cross-fertilisation process between the concept of resilience and building conservation. The authors discuss how the conservation field can address new issues posed by climate change and whether the concept of resilience plays a role within the framework of sustainable building conservation.Design/methodology/approach: Starting from the use of resilience as a “travelling concept”, different interpretations of the term emerging from different fields are compared and interrelated in order to understand how this concept can impact future research in building conservation.Findings: In addition to summarising recent developments in conservation theory with a special focus on how sustainability has influenced the field, this work also suggests some lines of research where resilience could foster interdisciplinary approaches to building conservation and presents some controversial outcomes.Originality/value: The paper raises a discussion on how the concept of resilience could renew the field of building conservation, helping contemporary society to address the challenges of climate change.

This work illustrates the contribution of flood risk assessment and adaptation to set up a conservation management plan for a masterpiece of 20th-century architecture. Case study is the iconic complex, internationally known as the National Art Schools of Cuba. It consists of five buildings built in the early 1960s within a park of Habana next to the Caribbean Sea. The path of the river (Rio Quibù) crossing the estate was modified to fit the landscape design. The complex has then been exposed to the risk of flooding. The School of Ballet, located in a narrow meander of the river, slightly upstream of a bridge and partially obstructing the flow, is particularly subject to frequent flash floods from the Rio Quibù, and it needs urgent restoration. Keeping ISA Modern is a project aimed at preserving the Schools complex. Based upon in situ surveys on the Rio Quibù and local area measurements during 2019, numerical modelling, and previous work by the Cuban National Institute of Hydraulic Resources, we pursued a flood risk analysis for the area, and a preliminary analysis of available risk reduction strategies. Using HEC-RAS 2D software for hydraulic modelling, we evaluated the flooded area and the hydraulic conditions (flow depth, velocity) for floods with given return periods. Our results show that SB is a building most subject to flooding, with high levels of risk. Defense strategies as designed by Cuban authorities may include a (new) wall around the School of Ballet and widening of the river channel, with high impact and cost, although not definitive. Temporary, light, permanent, and low cost/impact flood proofing structures may be used with similar effectiveness. We demonstrate that relatively little expensive hydraulic investigation may aid flood modelling and risk assessment in support of conservation projects for historically valuable sites. This may support brainstorming and the selection of (low to high cost) adaptation and risk reduction measures in the coastal areas of Cuba in response to ever increasing extreme storms and sea level rise controlling flood dynamics under transient climate change.

This article discusses how to sustainably manage and protect the Alpine landscape from the risk of extreme weather events due to climate change. The authors present the results achieved by applying the Conservation and Management Plan (CMP) method in the case of a large terraced healing park built in the Central Alps in the 1930s and damaged in 2018 by the effects of Storm Adrian (also known as Vaia). We thoroughly analysed the state of preservation through historical documentation, aerial shooting with a drone, a tree-by-tree evaluation, and a GIS platform for integrated information management. Such a CMP approach is usually applied to assess the state of decay and plan for the sustainable conservation of historic buildings and gardens. The method of analysis and the performed activities allowed us to evaluate the park’s landscape values and identify the elements of risk, leading to the drafting of a monitoring map and guidelines of intervention. This experience made it possible to test its effectiveness in protecting the Alpine landscape and its specific fragility.

An innovative and versatile set-up for in situ and real time measures in an electrochemical cell is described. An original coupling between micro-Raman spectroscopy and atomic force microscopy enables one to collect data on opaque electrodes. This system allows for the correlation of topographic images with chemical maps during the charge exchange occurring in oxidation/reduction processes. The proposed set-up plays a crucial role when reactions, both reversible and non-reversible, are studied step by step during electrochemical reactions and/or when local chemical analysis is required.
