“…There are not only material aspects to consider when retrofitting historical buildings. Users' behaviour has an important role to play in mitigating climate change, as it determines the preference and choice for room temperature and ventilation, for instance [38], and can help target specific groups in carbon reduction strategies. Many studies highlighted the high energy saving potential derived from changes in user behaviour [39][40][41][42][43], which they estimated to range from 62 to 86% [40].…”

Climate change mitigation targets have put pressure to reduce the carbon footprint of cultural heritage buildings. Commonly adopted measures to decrease the greenhouse gas (GHG) emissions of historical buildings are targeted at improving their energy efficiency through insulating the building envelope, and upgrading their heating, cooling and lighting systems. However, there are complex issues that arise when mitigating climate change in the cultural built heritage sector. For instance, preserving the authenticity of heritage buildings, maintaining their traditional passive behaviours, and choosing adaptive solutions compatible with the characteristics of heritage materials to avoid an acceleration of decay processes. It is thus important to understand what the enablers, or the barriers, are to reduce the carbon footprint of cultural heritage buildings to meet climate change mitigation targets. This paper investigates how climate change mitigation is considered in the management and preservation of the built heritage through semi-structured interviews with cultural heritage experts from the UK, Italy and Norway. Best-practice approaches for the refurbishment of historical buildings with the aim of decreasing their energy consumption are presented, as perceived by the interviewees, as well as the identification of the enablers and barriers in mitigating climate change in the cultural built heritage sector. The findings emphasise that adapting the cultural built heritage to reduce GHG emissions is challenging, but possible if strong and concerted action involving research and government can be undertaken to overcome the barriers identified in this paper.

“…The investigation of how users can implement non-intrusive energy efficiency measures in historic buildings was in particular focus. 13 A historic apartment building in a conservation area of Oslo was used as a case study for both technical surveys and interviews with owners and residents. The apartment building is a representative example of its time and consists of two buildings, one in front facing the street and one in the back.…”

“…Fouseki and Cassar 31 stated that 'studies of occupants' attitudes and behaviour with regard to energy-efficiency interventions are critical' when they addressed the topic and future research needs in their 2014 editorial. Berg et al 32 further concluded that residents represent an important resource that can foster lower energy demand and less intrusive interventions in historic buildings provided that they are included in the planning and follow-up phase of the refurbishment process.…”

This article presents and discusses the challenges of refurbishing historic apartment buildings by correlating findings from research projects LEAF and CulClim. Our aim is to shed light on how residents can partake in and optimise the refurbishment process after energy performance certificates (EPC) have been conducted. The background is that historic apartment buildings are generally more complex than single family buildings with respect to the energy efficiency process as they often have multiple owners with different priorities. The case studies from Norway and Sweden have conceptually contrasting energy performance certificate (EPC) systems. Identified advantages and shortcomings concerning both systems are discussed. In Sweden, the restrained recommendation of measures can lead to national mitigation targets not being realised. In Norway, excessive and unqualified recommendations risk reducing the cultural heritage values of the existing building stock as well as having a negative environmental impact on greenhouse gas emissions. A bottom-up approach incorporating the resident's objectives is presented and discussed. Results suggest that improved EPC-systems and a broadened procedural approach to decision making will ease the process and improve the outcome of the refurbishment with respect to both energy and heritage aspects.

“…Over the last decade, the need for adaptation, upgrading, and energy efficiency of historic buildings has been recognized as a key-theme in the debate for the definition of a new paradigm of sustainable development. In this sense, activities aimed at the revitalization and energyarchitectural upgrading of historic buildings with a high artistic and cultural value have raised great interest in the scientific community [1][2][3]. In particular, Italy, which represents the first country in the world for the number of UNESCO World Heritage Sites [4], is an excellent "laboratory" for the study and development of new restoration techniques able to combine conservation and energy efficiency.…”

Energy efficiency and environmental sustainability in building has become a key issue since the built environment is nowadays responsible for more than 30% of the total carbon emissions.While new building design and construction reached massive improvements toward net zero energy and high environmental performance standards, existing and historical buildings are still too much energy needy, with a relatively low indoor comfort conditions for both occupants and artworks preserved inside, especially within heritage buildings. Such high architectural value buildings correspond to almost one third of the Italian building stock and they typically need to be re-functionalized for hosting residential, office, or institutional uses, i.e. museums and exhibition areas. In this view, the present research aims at developing a replicable method for assessing and enhancing indoor comfort in historical buildings frequently characterized by too high relative humidity and thermal losses through the envelope. More in details, an innovative envelope material for indoor application, i.e. hygro-adsorbing plaster, has been tested in an ancient Italian castle and its effect has been assessed by means of coupled monitoring and calibrated dynamic simulation. The experimental campaign shows an increase of the Performance Index (PI) in terms of relative humidity acceptable range from 16.1% to 33.3% by applying the new thin plaster. Moreover, the results show that dedicated HVAC systems may support the action of passive strategies for preserving artworks and indoor comfort levels, but at the same time, such passive low-invasive strategies represent a mandatory first step toward energy efficiency, functional, and comfortable cultural heritage architectures.
