Austin Energy Green Building A Primer for a Discussion of Toxic Materials For the June Resource Management Commission Kurt Stogdill- Manager, Green Building & Sustainability Heidi Kasper- Manager- Residential Green Building Program Sarah Talkington- Manager- Commercial Green Building Program June 21, 2022 © 2020 Austin Energy Program Drivers Include… • Austin Energy’s Generation Resource Plan • City of Austin’s Climate Equity Plan • Project Connect Resource Plan • Austin Water’s Water Forward Integrated Water • Austin Resource Recovery- Zero Waste Master Plan 2 Other Drivers of Green Building Priorities • AEGB Mission- To cultivate innovation in building and transportation for the enrichment of the community’s environmental, economic and human well-being • Health- obesity, cardiovascular disease, diabetes, mental health • Climate- Carbon as well as hot humid climate and air quality • Equity, cost, up-front affordability • Building codes • Trends- building industry, regulatory, social, other… 3 Purpose/Goals of Ratings • To advance the communities’ understanding and application of sustainability practices in construction • To build capacity (around sustainability) within the market • To position new principles and concepts to be adopted as standard • To position critical new principles and concepts to be adopted as practices code • To be balanced in how they promote sustainability 4 Austin Energy Ratings Austin Energy Green Building (AEGB) rates new construction and major renovation projects for three markets Single Family Production & Custom Homes Multifamily Residential < 7 Stories Commercial & Residential ≥ 7 stories Ratings- Residential Example Ratings comprised of basic requirements, additional requirements by rating level and points 6 Areas in Ratings (Residential) Addressing Toxic Materials • Mechanical ventilation • Pest control systems • Indoor Environmental Quality • • Exhaust fans/vents Low VOC paints • Homeowner’s manual • PVCs and Phthalates Improved air quality • • Innovations 7 Toxic Materials Points (Residential) Category Education Requirement How is it Relevant list of finishes, list common

vented garage, HVAC filtration, formaldehyde free cabinets and shelving, safe sealants for hard surfaces, alternate certifications Also accept LEED/WELL points not expressly spelled out in AEGB ratings 9 Trends in Ratings Administration • Transition from “art” to science, highly technical • Addressing what is timely • Verification of effectiveness of measures • Get away from being overly prescriptive • Use pre-existing certifications • Streamline administration- minimize work required of both customer and staff to verify/support data and claims 10 Current Austin Energy Resources & Workload Ratings Staff Levels 18 16 14 12 10 8 6 4 2 0 2015 Staffing 2022 Staffing FTE Contractors Temps 11 Impacts of Growth • Have worked aggressively to minimize administrative burden of ratings • Suspended Integrated Modeling Incentive program • Have cut educational seminars down from 12/year to 6/year • Have suspended annual networking event, dropped level of support for Cool House Tour • Delayed progress on new projects to minimize embodied carbon, refrigerant capture and advanced grid integrated buildings 12 Staff Experience • 292 years of related experience • 6 Texas Professional Engineers (Civil, Mechanical, Chemical, Architectural) • 3 registered architects • 5 WELL AP (Accredited Professional) certifications • 13 LEED BD&C (Building Design and Construction) certifications • 1 member of the International Code Council Consensus Committee 13 Innovative Work Underway • Embodied Carbon- Dr. Wil Srubar’s Living Materials Lab at Colorado University- reducing embodied carbon in concrete, steel, other… • Grid Optimal- pilot with the New Buildings Institute to develop new metrics for building construction to support more effective grid operations • Equity- work with the NAACP, USGBC/LEED, local organizations • Toxic Materials calculator- budget request for ‘23 14 Scheduling Considerations • International Building Codes- every 3 years, 2024 is next • • • We expect to know the bulk of recommended changes to the ‘24 Codes within City adopts new codes when there are substantial changes worth adopting City has policy not to go more than 2 cycles (6 years) without adopting new code the next couple of months • Ratings updates- coincide with new code cycles every 3 years • • • Try to minimize mid-cycle changes Currently updating the Commercial Rating (including how we address toxic materials) Look to initiate Residential Rating update process this Fall and have it become effective next calendar year (2023) 15 RMC Toxic Materials Working Group Louis Stone- RMC Commissioner Rebecca Brenneman- RMC Commissioner Paul Robbins- RMC Commissioner Gail Vittori- Center for Maximum Potential Building Systems Gayle Borst- Architect Ray Tonjes- Green Home Builder Megan Matthews- Director of Design- Foundation Communities Trey Farmer- Architect 16 RMC Working Group- Proposed Schedule • Overview of Green Building Ratings- conducted 5/24 • • Reviewed this presentation Talked about workgroup composition Level setting on fundamentals of toxic building materials- 1 meeting • • Ecosystem overview- at least 2 meetings • Define what leadership looks like- 1 meeting • Understand impacts/drivers for key stakeholder segments- 1 meeting • Develop recommendations- 1 meeting 17 Thank You Questions?
