Tennessee lawmakers exempt low-sloped roofs from solar reflectance standards

The Tennessee State Legislature convened on February 12, 2025, to introduce Senate Bill 1194, a legislative proposal aimed at amending existing standards for roofing materials within the state. Sponsored by Senator Jackson, the bill seeks to exempt Tennessee from adhering to specific solar reflectance and thermal emittance requirements outlined in the International Energy Conservation Code (IECC) for low-sloped roofs.

The primary provision of SB 1194 is the addition of a new subsection to Tennessee Code Annotated, Section 68-120-101, which explicitly states that the aforementioned requirements of the IECC will not apply in Tennessee. This move is positioned as a response to concerns regarding the practicality and economic implications of enforcing such standards in the state’s roofing industry.

Debate surrounding the bill has emerged, particularly regarding its potential impact on energy efficiency and environmental sustainability. Proponents argue that the exemption will reduce costs for builders and homeowners, allowing for greater flexibility in roofing choices. However, opponents raise concerns that this could hinder efforts to promote energy-efficient building practices and contribute to higher energy consumption in the long run.

The bill's implications extend beyond construction; it touches on broader economic and environmental issues. By potentially lowering construction costs, SB 1194 may stimulate the local economy, but critics warn that it could also lead to increased energy costs for consumers due to less efficient roofing systems.

As the legislative process unfolds, stakeholders from various sectors, including construction, environmental advocacy, and energy efficiency, are closely monitoring the bill. The outcome of SB 1194 could set a precedent for future energy-related legislation in Tennessee, influencing how the state balances economic growth with environmental responsibility. The bill is set to take effect immediately upon becoming law, pending further legislative approval.
