6. Social barriers : rooted in acceptability and non-invasiveness conservation criteria, impede the integration of BIPV in historic buildings due to a prevalent lack of awareness, knowledge, and communication among citizens, stakeholders, and interdisciplinary experts, and a dearth of illustrative pilot projects and clear guidelines (Elena et al., 2017; Kalliopi et al., 2022; Kandt et al., 2011a; Sánchez-Pantoja et al., 2021) Combined with a lack of collaboration and co-creation among scientists, policy-makers, and professionals, there is a void in understanding and implementing viable BIPV solutions for heritage conservation contexts due to the lack of exploration of social acceptance and aesthetic impacts of renewable technologies.(Mete Basar Baypinar, Enes Yasa, Selahattin Ersoy, Cem Beygo, Kerem Beygo, n.d.) 2.3. Case study area The pilot city is Trondheim (lat. 63°25' N), ranks as Norway's third-largest city and a population of approximately 190,500 inhabitants. The selected study area is the historical neighborhood of Møllenberg. This neighborhood consists mainly of two-story wooden houses from the 1880s and 1890s Møllenberg was primarily a working-class neighborhood inhabited by families with children. In recent years, many of the wooden houses have been converted into student housing. (Fig 1).

Beside the difficulties in renovating because of the buildings’ significance, the climatic constraints remain the main limitation in Møllenberg as well as in similar high latitude sites subjected to significant seasonal and day length variations, prolonged period of darkness in winter, and low sun angles during winter and mid-seasons which lead to increased overshadowing by buildings and landscape, along with cooler temperatures due to the wider distribution of solar irradiation (Formolli et al., 2023; Westerberg & Glaumann, 1990). Notwithstanding, these sites become remarkably well suited for PV installation during summer. (Formolli et al., 2023; Westerberg & Glaumann, 1990). This potential has to be exploited to balance the preservation of the significance of a historical district located in a high latitude city (Sandvik, 2006) This research employs a multi-step methodology, initiating with an extensive literature review to evaluate challenges and barriers in solar technology implementation. A focused case study in Norway is then conducted to compare theoretical insights with real-world scenarios, allowing for the formulation of practical, validated guidelines to overcome the identified barriers suggested in fourth step. This approach aims to harmonize the integration of renewable energy technologies in historic areas by addressing the challenges both theoretically and practically.
