Besides challenges, it is crucial to address barriers on the integration of solar technology into historical setting. In that regard, legislation procedure is the most frequented cited barriers in the literature. From the review of some reports in Norway, it can be noticed that the lack of social acceptance is another relevant barrier to be addressed Fig 4 step 4 which illustrated by red full line box. • Legislative: The Møllenberg neighborhood in Trondheim is protected by heritage regulations, with Byantikvaren playing a pivotal role in advising on the cultural monuments and environments ( Byantikvaren , n.d.). The main obstacles are the complication of the authorization process and the lack of clear legal guidelines. More than Byantikvaren ’ s value, fire and safety, construction, and safety in Møllenberg can effectively stymie the adoption of RES solutions, requiring prolonged negotiations and adjustments to develop. • Social barriers : In Møllenberg, stakeholders including owners, tenants, the municipality, consultants, and Antikvaren encounter significant barriers due to a lack of awareness and communication regarding the implementation of Building Integrated Photovoltaics (BIPV). This lack of interdisciplinary collaboration and knowledge-sharing works as a barrier to utilizing solar technology with the respect to conservation within the area.

Fig 4 Summary of the workflow from the literature review to the analysis of challenges and barriers in the case study of Møllenberg. The study’s limitations may include a narrow geographical scope (Møllenberg, Norway) that limits the generalization of its findings to other historical areas with different cultural, social, or regulatory contexts. This could also restrict its broader applicability, as the legislative and technical challenges identified might not be globally applicable. Additionally, the paper does not fully capture the complexity of stakeholder ’s perspectives, such as local authorities or residents, which could provide additional considerations to the challenges, barriers, and opportunities. 4. Conclusion and further developments The increasing technical feasibility and economic viability deployment of RES systems, particularly on solar energy, make them suitable solutions to achieve net-zero emissions by 2050 towards a sustainable and low-energy transition process. However, their integration into urban built environment, especially historical neighborhoods, and buildings, is fraught with challenges and barriers. The hereby study explored these challenges and barriers in the context of Norway, with a specific focus on the neighborhood of Møllenberg in Trondheim. The literature review highlighted a range of conservation criteria/challenges and barriers that should be considered for the successful integration of solar technology systems into historical settings. Among these, reversibility, compatibility, and non-invasiveness emerged as pressing challenges and legislative procedure appeared most frequently barriers, suggesting a need for targeted
