Historic buildings in the UK are facing pressure to reduce their carbon footprint, with sustainable retrofits like LED lighting and heat pumps being easily implemented. However, solar technology integration faces challenges due to visual impact, despite UK heritage guidance allowing for solar integration. Building-integrated photovoltaic (BIPV) solar roofs offer a solution by blending into the architecture, as seen in examples like York Minster, Westminster Abbey, and Canterbury Cathedral. Roofit.Solar CEO Andres Anijalg emphasizes the importance of marrying historic buildings with modern climate solutions, showcasing the potential for genuine, scaled climate leadership that protects both the history of buildings and the planet they stand on.
