In alignment with Scottsdale’s overall building code updates, the city is preparing to adopt the 2021 edition of the International Green Construction Code (IECC) and the International Green Construction Code (IgCC). These updated codes will replace the currently adopted 2015 editions.
The IECC addresses residential and commercial energy efficiency on several fronts including cost savings, reduced energy usage, conservation of natural resources and the impact of energy usage on the environment. Key changes to the 2021 IECC improve efficiency by 11.1 percent and reduce greenhouse gases by 10.7 percent over the 2015 IECC. These changes include new provisions that increase efficiency and encourage greater flexibility in design and construction. Amendments include electric vehicle charging infrastructure for new homes, apartments and hotels to support future EV charging demand. The IgCC is applicable to new commercial buildings and contains measures to help mitigate heat island effect, reduce water waste, mitigate greenhouse gas emissions, support renewables, improve indoor environmental health and lower the impact on natural resources.
The updated codes are planned to be presented to City Council for adoption in the first quarter of next year. The IECC and IgCC have already received support from the Scottsdale Environmental Advisory Council and is currently being reviewed by the Building Advisory Board.
