About Eco-Integration

About Us  |  Affiliates


At Eco-Integration we believe that sustainability is about meeting the needs of society today and ensuring our children the same opportunity. It is the continuation and enhancement of life.

At Eco-Integration, we work with people to balance the sustainability triangle in the built environment. We will work with you to balance the three points of the triangle; economics, people and our planet in the design of your buildings.

Sustainable building design connects us to nature rather than separating us from it. By designing holistically we can find synergies that optimize energy and water use, lower operating costs, and provide healthier places to live and work.

The benefits are cost effective buildings, a healthier environment indoors and out, and happier people.


Diana Klein P. Eng., LEED BD+C & Homes, CSBA
Sustainable Design Consultant

Diana Klein BSc. LEED AP, P.EnDiana is a consultant and founder of Eco-Integration. She has over 25 years experience in the building industry as a structural engineer and sustainable consultant. She will bring to your building design her extensive project management experience and an ability to help you and your team embrace new ideas and attitudes.

She came to Canada from the UK in 1988 bringing a strong background in both integrated design and sustainable practices. She worked as a structural engineer with Read Jones Christoffersen Ltd. (RJC), a structural and building envelope engineering company for nearly 20 years. During this time her role evolved to becoming RJC’s sustainability specialist and researcher. Diana was the project engineer on the CK Choi Building at UBC (designed 1993). This project was a leader to embrace a holistic approach to sustainable design. She is respected in the building industry for the expertise and inspiration she brings to innovative sustainable design. Diana is dedicated to life-long learning and committed to the concept that sustainable building design will become the ‘norm’ for building design because it economically, socially and environmentally makes sense.

For the 2004/2006 term she was a board member of the Cascadia Chapter of the US and Canadian Green Building Council (the first dual citizen chapter). She is a past member of the executive for the Cascadia Chapter locally in Vancouver and part of the Outreach Committee.

The BC Green Building Code is a provincial government initiative to address issues around the contribution of buildings to climate change and energy use. Diana was a member of the APEGBC BC Green Building Code Task Force. This task force was represented at the Green Building Industry Advisory Committee presenting APEGBC’s feedback to Government. The BC Green Building Code was launched early 2008.
