Project Summary:
Driven by social, ecological, and economic value, the 21st-century renovation of New York City’s St. Patrick’s Cathedral—the prominent 1870s religious landmark by James Renwick Jr., which was last renovated in 1949— achieved a 29 percent reduction in annual energy use and stabilized significant historic fabric while each year welcoming 5 million-plus visitors. Design solutions combined stringent conservation methods, 10 geothermal wells, fully integrated new mechanical systems, and strategic architectural interventions to enhance worship and functionality. Additions of modern glass doors and structural glass walls supported sustainability goals, creating an energy-saving enclosure, improving uses of the 1906 Lady Chapel, and enhancing visitor comfort while maintaining views of historic interiors, stained glass, and structures. The nine-year, $177 million effort impacts the entire city block-sized campus. Preservation of failing marble, stone, plasterwork, and stained glass stabilized and improved original materials. New ancillary spaces create expanded social and worship opportunities, and 1960s-era mechanical equipment has been completely replaced. Long-concealed original elements were restored or re-created, with deference to Renwick’s neo-Gothic details and design intent. As reported in the New York Times, “trustees of the 138-year-old building, the centerpiece of the Roman Catholic Archdiocese of New York,” wanted the church to maintain its historic fabric, even as major systems were upgraded and “it was going green.” Offering valuable post-occupancy lessons for making historic places effective, relevant and resilient, the wide-ranging conservation and retrofit improvements to St. Patrick’s Cathedral created sustainable building systems and functionality with a focus on long-term, change-ready solutions. In this way, leadership invested in not only “the most sustainable, cost-effective, long-term options,” but also those “that best align with the greater good of the city, community and earth— not just today, but for generations to come.”
