A sustainable development strategist, Patricia has worked with real estate developers, timber companies, utilities, architects, local and state politicians, and senior city staff to expose them to global best practices. She has led over 40 professional research missions to cities in North and South America, Europe, Asia, Africa and Australia. She has served as the managing partner on research and communication projects for both the public and private sectors. Through both professional research missions and a variety of communication projects, she has facilitated the public and private sector coming together in a shared vision. She has co-authored a book entitled, “Envisioning Better Cities: A Global Tour of Good Ideas” with University of Washington professor Nancy Rivenburgh.

As a recognition of her work with I-SUSTAIN, Patricia was made an honorary member of the American Institute of Architects in 2007 “for creating a uniquely effective program to educate and inspire political and business leaders through international models of sustainable design and development.”

At the request of the Mayor of Seattle, Greg Nickels, she was a member of the 2008 Mayor’s Green Building Task Force, which provided guidance on appropriate policy mechanisms that would reduce the energy use of new and existing buildings by 20%. As a result of the task force, changes in the law regarding building energy disclosure requirements have been enacted in Seattle and have spread to other US cities.

Patricia has served as a Board Member of the Cascade Bicycle Club, the largest bicycling organization in the US. In 2010, she was made a Fellow with the World Affairs Council, and she was on the board of Great Cities, an urban advocacy group. She co-founded a non-profit organization, the International Sustainability Institute (ISI).

Patricia has always been an entrepreneur. Prior to I-SUSTAIN, from 1987 to 2001, she owned and operated Chase Bobko, a leader in the content management field. The firm had up to 200 employees at any one time, and worked for major corporations such as Microsoft, Boeing and Motorola along with many leading dot.coms. Chase Bobko was honored by the Washington State Software Association for creating and funding “Kids on the Web,” a program in the late 1990s in which Chase Bobko staff taught under-resourced teens web development skills.

Jayson Antonoff, LEEP AP, Principal at I-SUSTAIN, and Senior Technical Lead. Jayson consults with clients on a wide range of issues related to sustainability in the built environment. Jayson was previously with the Institute for Market Transformation (IMT), a Washington DC based NGO where he served as the Associate Technical Director for IMT’s Building Performance Policy team.  He was responsible for the promotion of best practices in mandatory policies and voluntary program design and implementation, drawing from both domestic and international experiences, and consulted with more than 30 state and local jurisdictions to help them develop strategies for reducing energy use in existing buildings.  Jayson has led numerous national stakeholder processes to inform the development of new tools and standards in this area, and served as the U.S. Director for the Global Buildings Performance Network, where he was responsible for researching and sharing information on international best practices to achieve energy efficient buildings.  He also served on the Carbon Neutral Cities Alliance Existing Building Performance Standards Advisory Group to develop guidance for cities committed to achieving deep reductions in their carbon emissions.


Jayson previously served as the Energy/Climate Change Policy Advisor for the City of Seattle’s Office of Sustainability and the Environment, where he developed and implemented programs to meet the City's goals for energy efficiency and greenhouse gas reduction, and led development of the City’s program for mandatory energy benchmarking of non-residential and multi-family buildings. He led the Mayor’s Green Building Task Force to solicit stakeholder input on next-generation policies for the City to pursue, and was instrumental in taking those recommendations and transforming them into new policies, programs and initiatives.  Jayson pioneered the City’s early efforts to implement an outcome-based code, which has since evolved into the building performance standards that have now been proposed or enacted in almost 50 jurisdictions nationwide. He began his career as an electrical engineer, responsible for the design of power distribution and control systems for airports and commercial buildings. Jayson holds a BS in Electrical Engineering from the University of Texas at Austin and an MS in Sustainable Energy Planning from Aalborg University in Aalborg, Denmark.
