In the heart of Granada, Spain, a groundbreaking study led by Mª Paz Sáez-Pérez of the Universidad de Granada is shedding new light on the thermal behavior of historic stone walls, with implications that could reshape the energy sector’s approach to heritage buildings. Published in the journal ‘Anales de Edificación’ (Annals of Construction), the research focuses on the Hospital Real de Granada, a monumental site that offers a unique case study for understanding the thermal dynamics of historic structures.
The study, which combines in situ thermal pattern analysis with computational simulations, reveals that the thick stone walls of the hospital play a crucial role in maintaining comfortable internal temperatures. “The existence of thick walls significantly improves the thermal behavior of the spaces,” Sáez-Pérez explains. This finding is particularly relevant as Europe pushes towards reducing energy consumption and carbon emissions through the rehabilitation of existing buildings, a goal supported by directives and funding from the Next Generation EU funds.
The research highlights the importance of understanding the unique thermal characteristics of heritage buildings, which often require tailored approaches for energy-efficient retrofitting. “The composition of materials and the building’s construction systems, along with their state of conservation, have a significant impact on thermal comfort,” Sáez-Pérez notes. This insight could guide future interventions, ensuring that historical integrity is preserved while enhancing energy performance.
The implications of this research extend beyond Granada. As cities worldwide grapple with the need to reduce energy consumption in historic districts, the findings from the Hospital Real de Granada offer a roadmap for strategic planning. By understanding the thermal behavior of historic stone walls, architects and engineers can design interventions that respect the original construction while improving energy efficiency.
The study’s emphasis on non-destructive testing methods also opens new avenues for conserving heritage sites. Traditional methods of assessing thermal performance often involve invasive procedures that can damage historic structures. By leveraging non-destructive techniques, the research paves the way for more sustainable and respectful approaches to heritage conservation.
As Europe continues to invest in the rehabilitation of its architectural legacy, the insights from this research could influence policy and practice. The energy sector, in particular, stands to benefit from a deeper understanding of how historic buildings can be adapted to modern energy standards without compromising their cultural significance. This balance between preservation and innovation is crucial for achieving the ambitious energy reduction targets set by the European Union.
The research by Mª Paz Sáez-Pérez and her team not only contributes to the scientific understanding of thermal dynamics in historic buildings but also offers practical guidance for future conservation efforts. As the world seeks to build a more sustainable future, the lessons from Granada could serve as a blueprint for preserving our architectural heritage while meeting the challenges of climate change.
