From September 17-22, 2017, i-SUSTAIN and the Center for Sustainable Infrastructure at Evergreen State College will lead a delegation of Washington state legislators and other elected officials to Denmark and Sweden to research sustainable energy infrastructure, investment and policy. The program will be in modeled on the success of i-SUSTAIN’s 2015 research mission for Washington state legislators and senior administrators from WSDOT and Gov. Inslee’s office, in addition to private sector participants, such as Puget Sound Energy.

The economic development portion of the itinerary will also include cross-laminated timber (CLT) structures and CLT's role in the region's economic development strategy.

Join us for an urban sustainability delegation to Vienna, Austria, from October 15-20, 2017.

For seven years in a row, Vienna has been rated #1 for quality of life. This Mercer rating includes social and economic conditions, health, education, housing, and the environment.

District Energy and CLT in British Columbia
i-SUSTAIN is organizing a two-day research mission to Vancouver, British Columbia, to examine district energy and cross laminated timber (CLT) projects. Site visits will include the University of British Columbia’s steam-to-hot water conversion project, presented by David Woodson, UBC’s Managing Director of Energy and Water Services. Join us, and learn about UBC becoming home to the world’s tallest CLT structure.

Please contact with your interest.

February 2016 
i-SUSTAIN spent over a week in Washington state interviewing executive level, influential leaders in the public, private, and NGO sectors.
Through our discussions, the following key themes emerged:  

- Combined Heat and Power and District Energy (including heating and cooling)
- Creating a Better Urban Environment
- Electrification of the Transportation Sector
- Cross-Laminated Timber (CLT)
- Managing Grid Operations with High Percentages of Multiple Intermittent Sources
- Community Energy Stories

March 2016
i-SUSTAIN led an Arts and Architecture tour to Havana and the Viñales Valley, Cuba. The program included an architectural bike tour of Havana, private tours of artist studios and workshops, art schools and museums, tours of neighborhoods, urban rehabilitation projects, and a classic car cooperative.

April 2016
i-SUSTAIN organized a series of district energy site visits and workshops in which high-level, influential professionals from Washington state, Denmark, Sweden, and other regions came together to work through issues related to financing, management of the conversion of steam to hot water, system expansion, and operations. Our efforts during these days were based on projects under serious consideration, including the University of Washington campus and the redevelopment of the Washington state capitol campus, along with district energy for smaller communities.

In addition to the invitation-only convening, two public sessions were held in Olympia and Seattle on ““How carbon pricing built the clean energy industry in Denmark”.  


June 2016
i-SUSTAIN developed an Urban Sustainability Delegation to Denmark and Sweden with input from members of the Bellevue City Council and City of Bellevue executives. Topics covered included: 

• Mobility: providing options for moving people safely and efficiently while using less resources.
• Economic growth and competitiveness: developing regional strengths to compete in a global market and attract high-growth industries.
• Clean energy infrastructure: incorporating micro-grids, smart technologies, neighborhood scale power plants, a greater amount of intermittent clean energy sources such as wind and solar which requires new ways of financing and planning.
• Affordability: Strategies for keeping cities affordable and diverse.

August 2016
i-SUSTAIN's summer alumni party was hosted by Susan Jones and her husband, Marco Zangari, at their highly sustainable home. Susan used her home to pioneer the use of cross-laminated timber (CLT), a construction material source that has the great potential to bring jobs and prosperity to forested communities in Washington state. For more on Susan's casually elegant "beach house" in the city, read this article.

October/November 2016
The momentum generated by the June 2016 delegation to Denmark and Sweden continued through a series of Bellevue site visits, workshops and a seminar: “Through the Gehl Lens: Planning for People”.

i-SUSTAIN brought in Gehl Institute experts from the Copenhagen headquarters and San Francisco offices for an exchange with City of Bellevue, Bellevue City Council, and King County on the status and aspirations for Bellevue’s Grand Connection (a non-motorized downtown corridor), public spaces, the Eastside Rail Corridor (ERC) transformation into a pedestrian and cycle path, and light rail station.

A tactical urbanism installation was situated very strategically at the site where major cycling/pedestrian infrastructure projects and a light rail station would intersect. The King County parks team, under the capable and enthusiastic leadership of Erica Jacobs, and with the support of Parks at the highest executive level, transformed an approximately 1000 feet (300 m) section of rail into a lit trail using a plywood foundation covered by faux turf, bordered by string lights on poles. This brought attendees to the "Enliven Wilburton Trailside Café," which provided protection from the rain and cold with canvas canopies and heat lamps. A very cozy Copenhagen-style café with food, drink, and live music by Choroloco, a Brazilian vintage jazz band, was created in spite of the weather, which was rainy and cold. This supported one of the goals of the event which was to highlight that outdoor public space, properly lit and protected from the elements, can be enjoyed much of the year.

Also, Gehl Institute conducted a “Action-Oriented, People-First Planning” seminar, which was attended by regional professionals in city planning, transportation planning, community development, public space enhancement, cycling infrastructure, policy, real estate, development, housing, chambers of commerce, commercial sector, and civic leadership.

November 2016
i-SUSTAIN brought architects from EXTENDA, the Trade Promotion Agency of Andalusia, Spain, to Los Angeles, San Fransisco, and Seattle to present the application of traditional Mediterranean concepts to contemporary architecture for reduction of energy and water use.
