Yianni Doulis is an architect and lead designer for Yianni Doulis Architecture Studio. He became LEED accredited in 2002, and his work has focused on sustainable design. He earned his Master's degree in Architecture from the Harvard Graduate School of Design.


Yianni Doulis: a certified green architect, interviewed on December 1st 2006 by Daniel Woodward, discusses his education background in architecture and engineering fused with his Portland background. He has travelled abroad many times to study the architecture of buildings, and his experience in green building was propelled by the knowledge he acquired in Germany, who he believes are ahead of any other country in terms of sustainable buildings. Buildings are for example, made to last much longer and more valuable, in order to use the space more sustainably, unlike the ethics and business of construction buildings in America. Tendencies here are to tear down completely and waste resources. Yianni emphasizes the lack of both the Federal Government investment in innovation for building, and the US market being basically structured in the short term theoretically, as a building only needs to be viable for 7 years to prove it worth instead of looking at it like a long term economic and design investment in society like in Europe. Building green can drastically change the ecologic footprint of an enormous project especially; when green materials that cost more are utilized the product becomes longer lasting, maintenance costs are lower, energy is used less, and green building can also entail reusable pieces at the end of life span.

This interview is part of “The Sustainability History Project: Documenting Sustainable Development and Practice in the Pacific Northwest” at Portland State University.
