| Structure | The article "Newness Touches Conventional History: The Research of the Photovoltaic Technology on a Wooden Church Heritage Building" presents a study on the restoration of a wooden church heritage building in Romania using photovoltaic technology. The study aims to explore the possibilities of integrating photovoltaic systems into traditional heritage buildings, while preserving their historical and cultural significance. The article begins by introducing the case study of a Transylvanian wooden church from Cojocna, Cluj county, Romania. The original design of the church assumed ICOMOS's charters and the recommendations from this area in quality design. The restoration work is not focused on energy efficiency, but rather on preserving the historical values and essential elements of the building. The article discusses the tension between preserving the historical identity of the building and incorporating sustainable technologies, such as photovoltaic systems. The first design version aims to preserve the traditional wooden shingle roof, while the second design version proposes replacing it with PV solar roof tiles. The article explores the strengths and weaknesses of each design version, including the preservation of identity, sustainability, and the potential for community engagement. The article presents the results of a preliminary investigation into the electrical energy production of the PV system. The study used software developed by the Technical University of Cluj-Napoca to calculate the solar position, angles, and energies. The results show that the PV electricity production under shading conditions represents about 40% of the estimated PV electricity production without shading. The article concludes that the integration of photovoltaic systems into traditional heritage buildings can be a viable solution for sustainable development. However, it also highlights the need to preserve the historical identity of the building and to engage with the local community. The study provides a framework for evaluating the potential of photovoltaic systems in heritage buildings and suggests that the design of such systems should be based on a holistic approach that considers the building's cultural, historical, and environmental significance. * The first design version aims to preserve the traditional wooden shingle roof, while the second design version proposes replacing it with PV solar roof tiles. * The PV electricity production under shading conditions represents about 40% of the estimated PV electricity production without shading. * The study highlights the tension between preserving the historical identity of the building and incorporating sustainable technologies. * The integration of photovoltaic systems into traditional heritage buildings can be a viable solution for sustainable development. * The design of such systems should be based on a holistic approach that considers the building's cultural, historical, and environmental significance. |
| Summary | The research focuses on the restoration of a Transylvanian wooden church from Cojocna, Cluj county, Romania, with the aim of preserving its historical values and introducing sustainable design elements. The original design follows ICOMOS's charters and the recommendation from the area in quality design, but the restoration work does not need to achieve any form of energy efficiency. The study explores two design versions: the first version preserves the original wooden shingle roof and the second version replaces it with PV solar roof tiles. The numerical values for electrical energy produced with photovoltaic technology are evaluated using homemade software validated by comparison with dedicated software (PHPP_V9.6; PVsyst 6.8.6). The results show that the PV electricity production under shading conditions represents about 40% of the estimated PV electricity production of the corresponding surfaces without shading. The second design version is considered a "transition design" between green/sustainable design and "designing regenerative culture." However, the lack of visual concordance between the old picture and the new one could create opportune disagreements, and the actual cost of PV technology is a significant concern. The research highlights the importance of adapting to changing world needs and considering the evolution of building parts in the context of technological revolution. The study concludes that the regenerative design could support a regenerative culture, but never without the identity represented by heritage buildings. |
