Update the building code to require pre-wiring for solar photovoltaics and electric vehicle charging infrastructure in new construction.
Designing solar-ready and EV-ready buildings is a low-cost strategy to encourage adoption of these technologies. Dallas already adopts and implements various building codes, including the IECC, to guide building construction and renovations. The 2018 IECC includes appendices that are not mandatory unless specifically adopted by cities, including Appendix CA Solar Ready Zone (commercial buildings) and RA Solar Ready Provisions (residential buildings). These appendices describe provisions to make buildings solar-ready, including accommodations for solar equipment, piping, and wiring, to encourage future installation of renewable energy systems. The City will adopt these appendices in the next building code update to support solar-ready construction. At the same time, the City will also include EV infrastructure requirements for new construction, including pre-wiring and electrical capacity, to accommodate future EV charging points. The City will evaluate the cost implications of these revisions for new residential construction and consider a waiver program for low income housing developments.
