This resource guide has been prepared in partial response to Los Angeles City Council motion CF#04-0074, Incorporate Rooftop Green Spaces as an Energy Efficiency Mechanism. This motion directed the Environmental Affairs Department (EAD) to lead the formation of a City task force for the purpose of developing and implementing “…a process, program, or procedure that will require City facilities to incorporate rooftop green spaces as an energy efficiency mechanism…” To support the Green Roof Task Force, the EAD researched green roof options and assembled information on numerous case studies and guideline development efforts in North America, Europe, and Japan. EAD subsequently utilized consultant assistance to expand and summarize the available research, determine its applicability to potential projects in the Los Angeles area, and incorporate practical and procedural information from the Task Force members into a plan for the development of green roofs in the City of Los Angeles. This document is intended to serve as a reference guide to facilitate green roof development by the City as well as other public entities and private building owners within Los Angeles.
