Bill Worthen Heading to Mexico City for 2016 C40 Mayors Summit


Bill Worthen is flying south. From November 30th to December 2nd, he’ll be in Mexico City for the 6th biennial C40 Mayors Summit event, joining an international group of mayors, urban designers and sustainability leaders to develop and advance urban solutions to climate change. Energy efficiency, low carbon transport, green growth and climate resilience will be explored through roundtable discussions, working sessions and presentations. Case studies will showcase innovative and successful sustainability projects from around the world.

Bill is excited to share Urban Fabrick’s work on water reuse, energy efficiency modeling and design, and climate resilience strategy. Here in the San Francisco home office, we’re thrilled to hear about the new ideas, information and insights he’ll be bringing back. We’ll be sure to keep you posted!


Bill Worthen, FAIA, LEED Fellow, GPR is currently focused on water re-use at the building and district scale and applying whole building Life Cycle Assessment (LCA) as a design tool. Bill wrote The Future of Designing (with) Water published in the January 2014 issue of ARCHITECT Magazine covering the challenges and opportunities for designing onsite water re-use systems, black and gray water technology and the water-energy nexus. Bill is also the sustainability consultant on 181 Fremont Street, San Francisco, a pre-certified LEED Platinum, 70 story mixed-use residential tower that is the first developer-driven project in San Francisco to install an onsite water reuse gray water system, saving over 1.3 million gallons of potable water a year.  Bill serves on the C40 Cities Roadmap Review Committee, the AIACC Energy and the Built Environment Steering Committee and holds the public seat on SF Municipal Green Building Task Force. Bill also created the Urban Fabrick Collaborative, a 501c3 focused on making sustainability fun, interesting and understandable to all.


Urban Fabrick assists project teams to meet, understand and design to new green building code requirements including CALGreen and the New York State Energy Code and a variety of local green building ordinances. We facilitate complex and high level green building certifications, onsite water reuse, net-zero energy design, sustainability master planning and climate positive development.

Urban Fabrick can help you to connect the dots and bridge many of the professional knowledge gaps that currently exist between today’s (business as usual) design practices and those required to successfully meet or exceed high performance (green) building code requirements, achieve green building ratings and make more informed, cost-effective and sustainable decisions. With over fifteen years of green building policy, practice and design expertise, Urban Fabrick adds value.
