Solar energy integration in heritage buildings. A case study of St. Nicholas Church

As climate change accelerates and operational energy burdens strain resources, protecting irreplaceable cultural heritage assets requires urgent prioritization to align preservation with principles of environmental and economic sustainability. Global building energy associated carbon dioxide emissions are projected to escalate over 50% by 2060 in a business as usual scenario, necessitating extensive retrofitting interventions. This research pioneer's solar technology integration methodologies for heritage sites by developing an original framework evaluating renewable addition feasibility based on comprehensive multi-criteria assessments integrating architectural, cultural, climatic and energy data analytic techniques with participatory planning essential for meaningful adoption. Outcomes aim conveying solar solutions as contemporary manifestations of custodial stewardship honoring artifacts from prior generations by sustaining their continuation using state-of-the-art environmental control modernizations. Demonstration case studies confirm site net-zero energy balances attainable today through 50% consumption reductions from envelope and lighting upgrades supplemented by distributed 20% efficiency building-integrated photovoltaic arrays sized under 50 W/m2 for negligible visibility or structural impacts. Controlled demonstration installations enable incremental capacity expansion validating projections to overcome reservations around inadequately modeled material impacts over full weathering exposure cycles. Participatory monitoring and contextual priority balancing thereby foster smooth logistical coordination and optimized generative restoration.
