Adrienne Etherton, Sustainability Management Analyst Comprehensive Commercial Building Efficiency Program • Ordinance to address energy and water use in existing commercial buildings • Extending benchmarking requirements to all commercial facilities, including most multi-family dwellings • Tiered auditing and retro-commissioning requirements that exclude the smallest buildings and high-performing facilities • Benchmarking, auditing and retro-commissioning would apply to both energy and water • Implement with extensive outreach, education and resources • Website/database for information-sharing, tracking compliance and public reporting • Resources on : auditing & commissioning programs, rebates & incentives, financing options, on-site renewable energy generation, fuel-switching, cleaner electricity, paybacks & other benefits • Partner with Brisbane Chamber on workshops, building owner trainings, audit demo event and outreach throughout the process • Share! • Present to RICAPS and other venues as requested/applicable • Toolkit of lessons learned and templates for other jurisdictions to replicate

Alice Zanmiller, Sustainability Planner, Marin County TITLE 24 AND REACH CODES FOR DECARBONIZATION
COUNTY OF MARIN GREEN BUILDING REACH CODE RICAPS Alice Zanmiller, Planner, County of Marin Sustainability Team June 24 th , 2018
LOCAL HISTORY & TIMELINE • 2005: Single Family Dwelling Energy Efficiency Ordinance • 2010: Marin Green Building, Energy Retrofit, & Solar Transformation (BERST) process • November 2016: Adoption of 2016 Title 24 standards, including maintenance update of previous reach code • March 2018: County BOS adopts updated green building standards • April 2018: New green building code implementation begins • June 2018 ( anticipated ): Full implementation of energy efficiency standards begins (large single family ZNE, multifamily and commercial new construction)
REASONS FOR UPDATE CLARITY FLEXIBILITY • • Project specific handouts Performance Standard • • Clearer language Multiple compliance options for • Fewer tiers, only square footage both EE and green building • • Updated website Agnostic towards rating system CONSISTENCY SUSTAINABILITY • Working with other jurisdictions to • Emphasis on all electric buildings adopt new standards ( ongoing ) • Near ZNE standards for new large homes >4,000 square feet
ENERGY EFFICIENCY – Single Family • New Single Family <4,000 square feet: Kept Tier 1, but added additional compliance options to incentivize all-electric homes • New Single Family 4,000 square feet and greater: – Mixed Fuel: 35% beyond baseline and EDR of 20 or less; OR; – All-Electric: 20% beyond baseline and 2.5kW of solar; OR; – Passive House
PV COMPLIANCE CREDIT CZ 2, Single Family Home No PV PV All Electric 0% 0% = CALGreen (State % More Energy Efficient than State Standards Baseline) -8.6% -5% -15% -10% -11.4% -15% -20% -25% % to be met through efficiency measures % met by PV Compliance Credit
ENERGY EFFICIENCY – Multifamily • No existing energy efficiency requirement – these are still pending CEC approval (anticipated mid-June). • 3 Stories or Less – Mixed Fuel & 10% beyond baseline OR; – Mixed Fuel + Solar & 15% beyond baseline OR; – All-electric at baseline • 4 Stories or More – Mixed Fuel & 10% beyond baseline OR; – All-electric at baseline
ENERGY EFFICIENCY – Commercial • No existing energy efficiency requirement – these are still pending CEC approval (anticipated mid-June). • All new commercial projects – Mixed Fuel & 10% beyond baseline OR; – All-electric at baseline
GREEN BUILDING • Changed to center around CALGreen, rather than Green Point Rated or LEED (but kept both as options) • All new buildings require CALGreen Tier 1 or equivalent GPR/LEED achievement • Residential additions + remodels <750 square feet don’t trigger additional requirements beyond state • Commercial additions + remodels <3,000 square feet don’t trigger additional requirements beyond state • All projects above these size thresholds trigger CALGreen Tier 1 (minus additional energy efficiency requirements)
ELECTRIC VEHICLES • Single family residential – all new projects & remodels altering the main service panel must comply with CALGreen EV Readiness requirements • Multifamily & Commercial New Construction: • Originally proposed 10% EV Ready and 10% EV Capable, but Board requested 100% EV Capable. • This proposal was accepted, but with a 20% cap on service panel capacity for parking spaces, and triggers for remodels that provide a nexus with the project scope.
LESSONS LEARNED & NEXT STEPS • Stakeholder engagement • Existing buildings remain a challenge – BAAQMD Grant – Ongoing energy efficiency programs – “New” Construction thresholds • Working with other jurisdictions to encourage adoption. • Will begin to revisit reach codes for next cycle as cost-effectiveness studies become available.
