Current requirements for new city-owned construction projects include:
- Recycle 85% of all construction and demolition (C&D) waste;
- Have 30% water savings beyond the Energy Policy Act of 1992 baseline code requirements;
- Use no potable water for building landscaping, except during first two years;
- Have 30% energy savings beyond LEED baseline requirements;
- Use building commissioning strategies required to be eligible for the Sustainable Building Business Energy Tax Credit;
- Include an ecoroof with at least 70% coverage and high reflectance and Energy Star-rated roof material on any non-ecoroof roof surface area. When an integrated ecoroof/Energy Star-rated roof is impractical, Energy Star-rated roof material must be used; and
- Incorporate renewable energy systems when possible or required by state.
Existing city-owned buildings installing a new roof must follow the guidelines specified above. All tenant improvements to city-owned facilities must be LEED for Commercial Interiors (CI) Silver and/or follow the Bureau of Planning and Sustainability's (BPS) High Performance Tenant Improvement Guide. All new commercial or mixed-use buildings over 10,000 square feet that receive financial assistance from the Portland Development Commission of $300,000 or more and that also equals 10% of the total project cost must achieve LEED Silver certification.
