Request for Proposals: Green Roof and Rooftop Agrivoltaic Potential: Assessment for Washington

The Washington State Department of Commerce is soliciting proposals from firms interested in participating in a project to explore the potential for “green roofs” in select Washington urban areas.

Work will focus on new non-residential buildings over 10,000 square feet.


The legislature appropriated funds to Commerce to conduct a cost-benefit analysis (CBA) on the use of green roof systems and agrivoltaics over the next 20 years. A green roof is a layer of contained vegetation which sits over a waterproofing system, installed on top of a flat or slightly sloped roof. "Agrivoltaics," for the purposes of this study, are the co-location of solar panels (photovoltaics) and food production on rooftops.


The objective of this work is to better understand the opportunity for green roof and agrivoltaic systems on new commercial buildings in densely-populated areas of Washington. Results of this analysis will support the development of policies and legislation to achieve increased green roof and rooftop agrivoltaic adoption in Washington cities.


Estimated contract period: Jan. 1, 2023 - June 30, 2023
