Sonja has been very effective in the research and analysis component of this project.  … The reports are filled with well-researched, highly detailed information that make a compelling case to decision makers.

Sonja has an incredible ability to network.  Over the course of the project she has established connections throughout North America and overseas.  This has strengthened the findings of her research by ensuring it stays abreast of the latest developments on the subject.   Her efforts to reach out have also resulted in a broader awareness of her work, contributions from experts in other fields and inroads to reaching key decision makers.  In the last year she has presented her work to municipalities, industry groups, government agencies, and NGO’s.  Most of these groups have been very enthusiastic about following up and the establishment of local energy retrofit programs…

Sonja’s ability to articulate how this financing policy fits into the larger issues of sustainability, social justice, and economics is indicative of her strong grasp on the host of issues at play.  She was able to adjust her messaging to be more effective in her engagement of selected audiences.

The management of this project has met every expectation.  Sonja is very well organized, managing her time effectively and coming through on time with deliverables.  She functions well in collaboration with others, working with different DSF staff members at the various stages of the project.  Sonja was successful in working within her budget, efficiently using resources to maximize the impact of her work…

Sonja’s professionalism, knowledge of key sustainability issues, attention to detail, and communication skills have made her the ideal person to carry out this work.

We thoroughly enjoyed working with Sonja over the past two years and appreciate the dedication and enthusiasm with which she carried out this project.”

The reports from the Suzuki Foundation “property-assessed payments for energy retrofits” (PAPER) are comprehensive and effectively presented. They are most useful for municipalities who are operating such a program or planning to do so.  Policy makers will find a ready-reference roadmap to the surest, most cost-effective energy reduction available.”

Review of Code, Regulatory and Systemic Barriers Affecting Living Building Projects:

"This report is both timely and important. The gravity of climate change requires that we move quickly to embrace deep improvements in energy efficiency and in use of renewables to achieve zero net CO2 buildings.  Building green is cost effective and provides both financial returns and a reduction of risk for owners and tenants. But as this report documents, there are widespread obstacles to adopting green design. This report maps out these obstacles in detail and provides a series of integrated recommendations to eliminate these obstacles and replace them with a regulatory environment that supports smarter, greener healthier design. It provides an important roadmap toward buildings that cut costs, cut risk, improve heath and allow us to live within our earth’s increasingly imperiled environmental means."

Both Johnson Controls and Siemens are our subscription clients and were very impressed with the ‘Green Buildings study’. They found it to be thorough and very insightful. Thanks again for the quality work you had done on this subject matter. We hope to continue our relationship with you and produce similar such great work.”

“Sonja has a broad academic and professional background which has prepared her to effectively combine social/environmental objectives with financial savvy. This is so badly needed in our society, but so seldom available. Sonja looks beyond the obvious, conducting a deeper analysis to discover other aspects of research that are not otherwise apparent. Her value to green building professionals also includes her ability to communicate benefits of complex technologies for promotional purposes or public education. She is self-directing, with motivation and imagination to get at the objective. An involved and articulate person, Sonja has a reasoning consistently aimed at benefiting environment and community enrichment. She has a wonderful ability to be a team player while remaining focused on the issue at hand.”
