ith the passage of Bill 25 in June, says Hawaii Energy Executive Director Brian Kealoha, “most new (City and County of Honolulu) construction will be required to make 25 percent of parking spaces EV-ready, which means building the necessary wiring and infrastructure to be ready to install electric vehicle charging stations at a later date. The new energy code also includes a point system to provide more flexibility for developers to meet this requirement.” The city’s EV-readiness requirements were presented via webinar in June, says Rocky Mould, energy program manager at the City and County of Honolulu’s Office of Climate Change, Sustainability and Resiliency. The presentation outlined the city’s two paths to compliance: a baseline percentage pathway and a points-based pathway.
