A new report released Tuesday, Delivering Urban Resilience, authored by Capital-E, quantifies the range of costs and benefits for the adoption of citywide smart surface technologies in Washington, D.C., Philadelphia and El Paso.

“Cities are increasingly at risk from hurricanes and severe summer heat,” said lead author Greg Kats. “This report shows how citywide adoption of these smart surface technologies would save cities billions of dollars and cut greenhouse gasses while achieving transformative benefits like making cities cooler, more resilient, healthier and more equitable.”

The report documents that an investment in these technologies would result in net present values of $1.8 billion in Washington, D.C., $3.6 billion in Philadelphia and $540 million El Paso over a 40 year period. The work is built on more than two years of data collection and research in collaboration with 15 organizations, including U.S. Green Building Council,American Institute of Architects, the National League of Cities, the National Housing Trust, the Chesapeake Bay Foundation and The JPB Foundation.

Delivering Urban Resilience is so critical because it is the first rigorous analysis of citywide surfacing options to manage sun and water at scale,” according to Mark Chambers, New York City’s Director of Sustainability.
