103A.7 State building code. 1. The state building code commissioner with the approval of the advisory council is hereby empowered and directed to formulate and adopt and from time to time amend or revise and to promulgate... reasonable rules designed to establish minimum safeguards in the erection and construction of buildings and structures... 2. The rules shall include reasonable provisions for the following: ... f. The conservation of energy through thermal efficiency standards for buildings intended for human occupancy and which are heated or cooled and lighting efficiency standards for buildings intended for human occupancy which are lighted. g. Standards for sustainable design, also known and referred to as green building standards.
Full Breakdown
Iowa adopts the International Energy Conservation Code (IECC) statewide under Iowa Code Chapter 103A, setting minimum insulation, window, lighting, and HVAC efficiency requirements for new buildings in Des Moines. Beyond that floor, the city's 2024 Climate Action Plan encourages voluntary measures, including LEED, ENERGY STAR Multi-Family, and Passive House paths, EV charging readiness, solar-ready roofs, and heat-pump installations. Some city-funded affordable housing and capital projects must meet enhanced sustainability standards by policy. State law preempts local energy codes that exceed the state-adopted version, so private developers cannot be forced beyond the IECC, but they can earn incentives or expedited review for green features.
Violations & Fines
Failing to meet the state-adopted IECC during plan review or inspection delays certificate of occupancy, while voluntary green commitments tied to incentives may be clawed back if not delivered.
