Sustainability Advisory Board Minutes June 21, 2023 Page 5 of 6 member: Rec. Center rooftop hot water heaters. McKinstry: Some of these topic areas are challenging from a longevity perspective. This plan (IDP) can and should be revisited in 5-7 years for a refresh and reevaluate if hybridization is still the pathway forward or if full decarbonization is better at that time. Considering retiring HVAC systems early has to take into account embodied carbon vs electricity not being clean and having natural gas as a back-up. City is currently 4% of total community -wide emissions. LSAB member: Only one EV charger at the golf course? Can we get more? Apt. buildings can use the charger/s at the golf course. McKinstry: There will be 8 spots total and the electrical charging is being looked at. There is no established follow-up to ensure this happens. Staff support and especially Public Works support. Breaking the IDP into 3 phases will help with accountability and much of this outlined and people/depts will be identified for next steps pending Council approval. LSAB Direction: Outline for memo includes: endorsing the schedule, emphasize the commitment to accountability (adoption is different than implementation), hybridization vs full decarbonization recommendation w/ recommendation to revisit plan in 5-7 years (LSAB member: Hybrid is more fiscally responsible), recommendation for goal past 2030, City -owned solar vs continuing to rely on Xcel, and recommendation to fully investigate grant options.
