HYPERION aims to leverage existing tools and services (e.g., climate/extreme events models, and their impacts, decay models of building materials, Copernicus services, etc.), novel technologies (terrestrial and satellite imaging for wide-area inspection, advanced machine learning, etc.) to deliver an integrated resilience assessment platform, addressing multi-hazard risk understanding, better preparedness, faster, adapted and efficient response, and sustainable reconstruction of historic areas.
Recent studies highlight the potential impact of Climate Change (CC) and geo-hazards (such as landslides and earthquakes) on historic areas hosting Cultural Heritage sites and monuments, which in turn yield significant adverse impacts on economies, politics and societies.
The deterioration of Cultural Heritage (CH) sites is one of the biggest challenges in conservation; aspects such as building technologies/materials, structural responses, preventive measures and restoration strategies, resilience and adaptation methodologies must be considered.
Currently there is no specific process towards understanding and quantifying CC effects on historic areas; combined with the limited strategies on CC-related issues, it becomes difficult to assess quantitatively and qualitatively the impact of various climatic and other parameters on the CH sites.
These issues form an integral part of the necessary support that should be provided to governmental bodies and cultural authorities to properly adapt their policies, in the short and long term, towards deploying sustainable mitigation plans and providing efficient reconstruction of the CH parts that have been damaged. Finally, the absence of social and humanities, and communities’ participatory aspects to the overall resilience and reconstruction planning of the historic areas is a main challenge to tackle.
In HYPERION resilience offers an overarching strategy that includes risk management, protection and preparedness as complementary strategies to prevent damages to Cultural Heritage (CH) sites, identify and ward off additional threats and promote adaptation, reconstruction and other post-disruption strategies to restore normal conditions to the historic area, as well as long-term strategic approaches to adapt to Climate Change (CC) and to wield policy tools for economic resilience.
To achieve that, HYPERION aims to introduce a research framework for downscaling the created climate and atmospheric composition as well as associated risk maps down to the 1x1 km (CH site) scale. Applying atmospheric modelling for specific CC scenarios at such refined spatial and time scales allows for an accurate quantitative and qualitative impact assessment of the estimated micro-climatic and atmospheric stressors.
HYPERION will perform combined HT and SG analysis of the CH sites (indoor climate, HVAC, moisture and air transfer through walls, roofs and foundations, and related strains and stresses) and damage assessment under normal (past) and changed (future) conditions (anthropogenic or/and natural disasters), based on the climatic zone, the micro-climate conditions, the petrographic and physical-mechanical features of building materials, historic data for the structures, the effect of previous restoration processes and the environmental/physical characteristics of the surrounding environment.
The data coming from the deployed sensors will be coupled with (and utilised also to update) simulated data over the wider CH area (under HRAP) and will be further analysed through our data management system and support communities’ participation and public awareness through the use of an already sucessful EU project: PLUGGY. The data from the sensors will feed the DSS to provide appropriate adaptation and mitigation strategies, and support sustainable reconstruction plans for the CH damages to the vulnerable assets. The HYPERION system ends up to an enhanced visualization tool with improved 4D capabilities (3D plus time) that can provide a simple and easy way for all relevant stakeholders to assess damage and risk.
The produced vulnerability map (based on the produced climate risk regional models) will be used by the local authorities to assess the threats of CC (and other natural hazards), visualize the built heritage and cultural landscape under future climate scenarios, model the effects of different adaptation strategies, and ultimately prioritize any rehabilitation actions to best allocate funds in both pre- and post-event environments.
The overall results will inform the employment of appropriate physical, organizational and financial tools to support resilience, including (a) structural rehabilitation interventions and associated policies (b) load-balancing reciprocal agreements between local businesses of the same type and (c) financial risk transfer tools (community/municipality insurance plans, single/multi-hazard insurance-linked securities) that can offer low-cost financing within hours of any extreme event, to jumpstart an immediate reconstruction effort.
