Description

As outlined in the 2022 Global Status Report for Buildings and Construction, the construction industry plays a significant role in the ongoing climate and environmental crises, with approximately 37 percent of CO2 emissions and the exploitation of valuable non-renewable resources attributed to it. The fragile mountain environment serves as a sensitive indicator of the impact of these crises, as evidenced by hydrogeological instability, soil erosion and glacial melting. Concurrently, global warming and pollution give rise to the phenomenon of vertical migration, which describes the movement of population groups to higher altitudes to seek out more favourable living conditions. This phenomenon creates a demand for living spaces in mountain areas, which potentially gives rise to further construction and exploitation of resources. It is therefore essential to engage in discourse on methods for mitigating the impact of construction on the mountainous environment. The goal of the focus session is to gather contributions that investigate the limitations and critical issues, as well as good practices and architectural solutions within the context of mountain areas. The focus session will address several key topics, including:

  • The sustainable and responsible use of local resources, such as timber, with a view to circularity.
  • The reuse of abandoned or underused building stock.
  • The reconsideration of different forms of energy production and consumption.
  • The creation of innovative spaces with peculiar community and social characteristics.

Baukultur as a driver for a renewed awareness of the impact of constructions on the environment

Matteo Tempestini

Abstract/Description

To maintain the delicate balance of the Alpine environment, the development of a sustainable built environment is essential. Over the last thirty years, some Alpine regions have included architecture and the quality of the built environment at the heart of their policies. Among these, two regions in the Central Alps, Graubünden in Switzerland and Vorarlberg in Austria, stand out for their active promotion of a conscious and widespread building culture, not only among professionals and experts in the field, but also among the general public. The aim of this paper is to provide an overview of these policies and the cultural initiatives implemented by the two regions from the end of the last century to the present day. These initiatives include architecture awards, exhibitions, various publications and the establishment of institutions dedicated to the promotion and communication of architectural culture, such as the Bündner Heimatschutz in Graubünden and the Vorarlberger Architektur Institut in Vorarlberg. In addition, through the description of distinctive architectural case studies, the paper will show how this widespread Baukultur has contributed to an increased awareness among the population of both regions of the environmental impact of construction. It will explore how this awareness has fostered a greater commitment to sustainability. By examining these paradigmatic examples of Alpine architecture, the paper seeks to understand how different tools for promoting and critiquing architectural projects – through their narratives and historiographies – can influence the development of a specific architectural culture and contribute to the creation of high quality, thoughtful architecture.

How to rebuild after the Al Haouz earthquake using local materials in a context of accelerated global warming (Morocco). Analysis of two pilot projects.

Salima Naji
Goeury, David

Abstract/Description

Post-earthquake reconstruction is based on the buidt back better principle. However, in a context of triple pressure – the imposition of new anti-seismic standards, the injunction to rebuild quickly, and the deployment of opportunistic operators – the new architecture favours standardised exogenous materials (steel and concrete) despite their unsuitability for mountain climatic conditions. Reacting to post-disaster emergencies therefore increases people’s vulnerability to gloabal warming. We will be presenting some pilot experiments carried out since January 2024, which provide an opportunity to outline alternative strategies. The first concerns the issue of repairing historic buildings and reinforcing them using historic techniques to improve their resistance to earthquakes. The second is the construction of new buildings combining contemporary uses and local historic techniques. What these two strategies have in common is that they are based on the availability of local materials (earth, stone, wood) and the reactivation of historic know-how in a paleinnovation process. Exogenous materials are used to achieve certain regulatory construction performances. They enable buildings to have a very low carbon footprint and a very low environmental impact throughout their life cycle (construction, maintenance, operation, but also when they are destroyed). They also pose a societal choice between capital-intensive and labour-intensive construction approaches. Indeed, it seems necessary to consider how to maintain a skilled, respected and well-paid local workforce if we are to maintain constructive autonomy in mountain areas.

Abstract/Description

Alpine Clubs play a vital role as stewards of mountain environments, safeguarding both the natural landscape and essential infrastructure. At the heart of this network are mountain huts, high-altitude outposts, serving as both shelters and gateways to the alpine territory. However, these buildings face growing pressure from climate change, which is impacting mountain ecosystems at nearly twice the rate of urban areas. Simultaneously, increasing tourism further strains these often aging buildings, exacerbating their environmental impact and operational costs. Unlike urban infrastructure, mountain huts lack centralized data, making effective renovation strategies difficult to define. To address this, a comprehensive methodology has been developed to assess the sustainability performance of the Italian Alpine Club’s Mountain huts and support their adaptation to climate change. Developed by a strong synergy between Montana Spa, Politecnico di Milano’s Department of Architecture, Built Environment, and Construction (DABC) and CAI-Italian Alpine Club, this project introduces and discuss a preliminary test of a new sustainability rating framework developed for mountain huts. The methodology establishes a dual grading approach differentiating between technical/performance characteristics, such as wall’s insulation and wastewater treatment type, and management practices. This large-scale assessment tool ensures a balanced evaluation that aligns sustainability with the operational realities of hut management. The system seeks to reconcile financial sustainability with CAI’s commitment to environmental responsibility, seeking both economic viability and conservation values. This rating system lays the foundation for a long-term renovation strategy within a broader European legislative framework. By structuring and centralizing data, the system enables evidence-based decision-making, helping CAI define staged deep renovation plans, optimize public investment and reduce the overall mountain huts carbon footprint. Integrated into a Building Renovation Passport (BRP) approach, it empowers CAI to prioritize actions, strategically allocate resources, and enhance the resilience of mountain huts. Ultimately, this tool aims to improve the quality of the hut experience while preserving these fragile structures in a rapidly changing climate.

The living spaces in the mountains: between climate migrations, youth return practices, and new communities.

Federica Serra

Abstract/Description

After decades of depopulation and abandonment of highland areas, recent years have witnessed a phenomenon of return to the mountains. The effects of climate change and the pandemic experience, alongside the search for new, more sustainable ways of living closer to nature, have driven large numbers of people—mostly young—toward high-altitude territories. These new inhabitants appear to be a positive response to the challenges faced by these areas. In theory, everything seems to work, yet long-abandoned mountain regions now struggle to provide sufficient living space. Why? What mechanisms are preventing this potential reversal of trends? What role can architecture play in facilitating this process? Starting from these considerations, this research aims to highlight, on the one hand, the reasons why housing demand remains unmet in mountain areas, and on the other, the perspectives that architecture can offer to local authorities and third-sector organizations in terms of interventions on public assets. These interventions could generate new, innovative, and shared housing solutions. The study is structured through examples of action-research across the Italian territory, from the Alps to the Apennines, showcasing good local practices in design, community engagement, and governance. These micro-insertions into a vast territory represent the first sparks of a broader strategy for mountain habitation. They must soon be scaled up at regional and national levels to create the conditions for the long-sought repopulation of mountain areas.
