Atlanta City Council introduces ordinance for cool roofing standards to combat urban heat

The Atlanta City Council's City Utilities Committee convened on May 27, 2025, to discuss a significant ordinance aimed at amending the city's building code to promote the use of "cool roofs." This initiative, spearheaded by Council Member Liliana Bakhtiarri and supported by several colleagues, seeks to implement roofing standards that reduce heat absorption from darker materials, thereby addressing urban heat island effects and contributing to climate resilience.

The proposed legislation is designed to ensure that new roofing installations utilize lighter-colored materials, which can lower the city's overall temperature by an estimated 2.5 degrees if adopted widely. Bakhtiarri emphasized the cost-effectiveness of this measure, noting that it would not impose additional financial burdens on the city or homeowners. The ordinance is expected to be dual-referred to the Community Development and Human Services (CDHS) committee for further discussion.

During the meeting, council members raised questions about the implications of the new standards, particularly regarding compliance costs for homeowners and the potential impact on the construction industry. Alex Fennell, Bakhtiarri's Chief Policy Officer, clarified that the ordinance would not require expensive materials, as many compliant roofing options are already available at similar costs to traditional materials. This approach aims to balance environmental benefits with economic feasibility.

Concerns were voiced about the lack of a phased implementation period, which is typically standard for new regulations. Some council members expressed the need for more extensive communication with industry professionals to ensure a smooth transition to the new standards. The ordinance will also undergo a review process by the Office of Buildings, which has 90 days to provide feedback before the regulations are formally adopted.

The discussions highlighted the broader context of sustainability and energy efficiency in Atlanta, particularly as the city grapples with rising temperatures and the need for affordable housing solutions. The committee's deliberations underscored the importance of integrating environmental considerations into urban planning and development, with the potential to alleviate energy burdens on residents, especially vulnerable populations.

As the ordinance moves forward, the committee anticipates further discussions in the upcoming council meeting, where the implications of the proposed roofing standards will continue to be evaluated. The outcome of this legislation could set a precedent for similar initiatives in other cities, positioning Atlanta as a leader in sustainable urban development.
