The Office of Sustainability and Environment (OSE) is conducting stakeholder and community engagement on creating draft legislation for new City of Seattle regulations for commercial and multifamily buildings. The draft legislation would apply to commercial and multifamily buildings 20,000 square feet and larger and would reduce climate-polluting emissions and transition towards cleaner, healthier places to live and work. Called ‘Building Performance Standards,’ these carbon emissions targets would become gradually stronger over time towards a goal of cleaner, healthier, ‘net-zero’ carbon emissions buildings by 2050.
