Seattle is again making waves in the fight against climate change with the introduction of Draft Director's Rule 2-2025. Published recently, this rule aims to raise the city's green building standards, building upon the foundation set by its predecessor, Director's Rule 4-2021. As the Seattle Department of Construction & Inspections reports, the new rule is poised to refine site development mandates, specifically focusing on lowering embodied carbon and simplifying the paperwork builders face during application.
The green scene in Seattle has been thriving for the past 16 years, thanks partially to incentives provided to developers who dared to go green. These incentives, which include extra floor area and height, have resulted in thousands of green building certifications and have helped curb the city's greenhouse gas emissions significantly. Under the new rule, certification programs such as Built Green, Phius, and The Living Building Challenge remain recognized, but updated to their most current iterations for compliance with the city's standards.
In energy efficiency, the bar has been raised for developers using the Leadership in Energy and Environmental Design (LEED) certification. Once Gold was sufficient, the Seattle Energy Code's mandate now calls for 'Platinum' status under LEED versions 4.0 or 4.1 for certain construction permits. However, Gold maintains its standing as the minimum for projects that fall under the 2018 code. While LEED Gold projects, as mentioned on the Seattle Department of Construction & Inspections, often max out their energy points by just meeting the building code, certifications like Built Green reflect comparable standards to LEED Platinum with a reliance on Washington State's codes.
