ATLAS

EU AS ATLAS, Advanced Tools for Low-carbon, high-value development of historic architecture in the Alpine Space

Only if we intensify our efforts to vlorize und use sustainably historic buildings we will be able to both meet the ambitious climate mitigation targets and protect the intrinsic characteristics of the Alpine cultural landscape. This task is a mission for the whole civil society. The ATLAS Project Targets the (re-)discovery of - not only listed - traditional architecture (buildings and ensambles). These buildings are often located in deprived areas and provide low levels of energy efficiency and comfort. The project aims at paving the way for sustainabkle development of the historic structures. This will include capitalizing and optimizing existing best practice solutions for building refurbishment and regional development. Stakeholders of the whole value chain and decision-makers are included in a Network to ensure sustainability from social, ecological and cultural point of view.

Guidelines for renovation of historic buildings

These guidelines are intended to explain to interested owners as well as professional planners the fundamental steps towards the concept definition for a sustainable renovation of a historic building providing a basis for further planning and implementation.

Evaluating the Implementation of Energy Retrofits in Historic Buildings: A Demonstration of the Energy Conservation Potential and Lessons Learned for Upscaling

Herrera-Avellanosa D, Rose J, Thomsen KE, Haas F, Leijonhufvud G, Brostrom T, Troi A

Alexandra Troi

This study presents an in-depth analysis of 69 case studies focusing on the energy retrofit of historic buildings, uncovering challenges, best practices, and lessons learned to balance energy efficiency improvements with heritage preservation. The findings highlight several challenges encountered during renovations, such as complex heritage evaluations, restrictions on alterations, coordination issues with authorities, technical limitations, higher investment costs, and knowledge gaps. On the other hand, identifying factors promoting renovation, including demonstrating energy savings while respecting heritage, early collaboration between planners and authorities, and quantifying investments, could incentivize owners and authorities. The limitations of a still-limited sample size, occasional incomplete data, and potential sample bias call for cautious interpretation of the presented analysis. Despite these, the study provides valuable insights into successful projects, emphasizing the need for scalability, knowledge transfer from innovative policies, and targeted policy-making for successful replication. The study concludes with a call for further development of the HiBERatlas (Historic Building Energy Retrofit atlas), an extensive resource for historic building renovation, expanding its database, collaborating with agencies, and tailoring guidance for stakeholders to foster energy retrofits in heritage buildings.

A new decision guidance tool for the adoption of energy retrofit solutions in historic buildings

Rieser A, Leonardi E, Haas F, Pfluger R

Eleonora Leonardi

Energy retrofit of historic buildings often represents a challenge for owners and practitioners due to the lack of knowledge and access to suitable solutions. The growth of awareness and interest in sustainability has caused an increase in the number of solutions available for improvement of historic buildings’ energy performance. What it is still missing is their dissemination across the involved stakeholders. This will improve practitioners’ trust on these solutions and the adoption by owners in the building renovation. In the framework of IEA SHC Task 59 and the Interreg project ATLAS, experts have collected well established and innovative solutions for historic building renovation presented in an online decision guidance tool. The set of solutions is structured in four groups: wall insulation, window solutions, solar systems and HVAC systems. For each group a decision tree was developed to guide the end-user with questions to the appropriate solutions for their building. The tool aims to inspire and motivate technicians and owners with a large number of possible solutions, which serve as a basis for further investigation and planning. With more than 130 documented solutions it is already a comprehensive tool that can be used as basis and extended in future.

Strategies and tools for potential assessment of Renewables (RES) in Alpine Space areas valid for historic buildings and sites

Polo López CS, Bettini A M, Khoja A, Davis A M, Hatt T, Braun M, Kristan M, Podgornik J,

Within the framework of ATLAS research project (Interreg Alpine Space Programme 2014-2020. ID: ASP644) experts of different countries of the Alpine arc studied and compared the measures implemented in the various countries to strengthen and further promote the implementation of renewable energies at the local level. This study highlights those strategies and existing tools for potential assessment of renewables taking into account the applicability for historic buildings, pointing out similarities and differences as model reference between the different territorial areas. The work aims to disseminate and capitalize on the best practical experiences on the topic, and to engage as many stakeholders as possible for a wider implementation of renewable energies in the territory of the Alpine arc. Direct examples of implementation at regional and local level to exploit RES while preserving the authenticity of historic buildings and settlements to be protected in the different countries and regional areas of Alpine Region are shown exploiting their full potential with practical advice for model regions.

Water absorption characterisation of historic plasters. Comparison of different methodologies in a case study in Tyrol, Austria

Herrera-Avellanosa D, Leonardi E, Rieser A, Haas F

Eleonora Leonardi

Balancing conservation of historic buildings and improvement of their energy performance is a challenging task that involves multiple factors. Prescriptive standards for interventions of internal insulation in modern materials are not compatible with conservation of historic plasters and thus a more detailed and sympathetic approach must be used. Knowing the hygric behaviour of historic plasters is a prerequisite in the assessment of any intervention of internal insulation. In this paper, four different methods for the quantification of the water absorption coefficient, laboratory and onsite based, are presented and applied to an outstanding case study in Tyrol (AT). The variability observed, between methods but also between the different layers of plasters found onsite and even between measurements, highlighted the need for robust guidelines for the application and interpretation of the results. This study summarises the numerous factors influencing the result of the water absorption measurement and shows a first investigation into one of these aspects (heterogeneity of the wall). Numerical simulation has proven to be an effective tool to use in combination with experimental results in testing the effect of the different parameters affecting the water absorption characterisation of historic plasters
