City of Portland Supplement to the LEED Rating SystemTM 2 INTRODUCTION

The City of Portland Supplement to Leadership in Energy and Environmental Design (LEED) 2.0 Green Building Rating SystemTM was developed by the City of Portland in 2002 to identify both local and state codes that go beyond LEED requirements and additional green building strategies that are regionally significant. It is designed to encourage both public and private sector commercial and mixed-use projects in Portland and Oregon to meet LEED certification. A working group of public and private sector stakeholders, facilitated by the City’s Office of Sustainable Development, developed the Portland Supplement in 2000-01.

In 2001, the City adopted a Green Building Policy requiring new construction and major renovations of all city facilities meet the Certified level of LEED. While the Policy targets all new construction and major retrofits of city owned facilities, the City recognizes that LEED 2.0 is not appropriate for every building type and programming need. Therefore the Policy was designed to include a variety of tools targeted at specific building types including tenant improvements (T/I) and operations and maintenance practices when they become available. In addition, a list of exempted building types is currently being developed for city-owned buildings that aren’t appropriate for LEED 2.0 certification (small out buildings, sheds, pump stations, etc.).

In 2001, the Portland Development Commission adopted a similar policy requiring LEED certification for all publicly financed (over $200,000 in PDC financing) private sector projects larger than 10,000 S.F. Both policies are helping move environmental building practices and LEED certification forward in the Portland market. In addition, the Oregon Office of Energy recently expanded the state Business Energy Tax Credit (BETC) to include LEED Silver and higher rated buildings, providing a powerful incentive to developers and building owners to design and build to the LEED standard. The Portland Supplement to LEED helps meet local environmental objectives and streamlines regulatory requirements providing a powerful tool for increased market penetration of high performance, healthy commercial and mixed use buildings throughout Portland.

Certification The City of Portland Supplement is a LEED guidance document. All projects must register with the U.S. Green Building Council (USGBC) and follow documentation and submittal requirements as described in the LEED Reference Package. USGBC will review each application in its entirety, including Portland-specific credit modifications and supplements. An additional processing fee may apply. Applicants must clearly note that they are using the City of Portland Supplement at the time of registration and within the application submittal (in the project narrative and on the application’s cover).
