Arizona’s New Commercial Building Energy Efficiency Standards Are Reshaping the Roofing Industry – Here’s How to Stay Compliant in 2024
Arizona’s commercial building sector is experiencing a significant transformation as updated energy efficiency standards take effect in 2024. With the majority of new construction activity occurring in jurisdictions that have adopted the 2012 IECC or 2018 IECC, and Arizona being a home rule state where codes are adopted and enforced on a local level, property owners must understand how roofing upgrades play a crucial role in meeting these evolving compliance requirements.
Understanding Arizona’s Energy Efficiency Landscape
All state-funded buildings constructed after February 11, 2005 must achieve LEED Silver certification and meet the energy standards of ASHRAE 90.1-2004 as mandated by Executive Order 2005-05. However, the standards extend far beyond public buildings. The Arizona Corporation Commission (ACC) adopted rules in August 2010 and December 2010 requiring certain electric and gas utilities in the state to meet prescribed energy efficiency requirements by 2020, creating a ripple effect that influences commercial building design and construction throughout the state.
Energy efficiency standards hold a central role in Arizona’s building codes, particularly given the state’s hot climate. These standards aim to minimize energy consumption and lessen the environmental impact of residential buildings. For commercial properties, this translates to stricter requirements for building envelope performance, including roofing systems that must demonstrate superior thermal resistance and reflective properties.
The Critical Role of Roofing in Energy Compliance
Commercial roofing systems are arguably the most important component for achieving energy efficiency compliance in Arizona’s extreme climate. For a roof to be energy efficient, it needs to do a good job of blocking the heat out instead of absorbing it. When a roof absorbs heat, that warmth is transferred into the air inside the building radiantly, and pretty soon the entire interior has gotten much warmer. A roof that bounces the sunlight off and reflects the heat back out into the atmosphere will do a much better job of protecting the home or business from hot air.
Cool roofing is probably the most popular and effective energy-efficient roof for commercial properties in Arizona. These systems utilize materials with high solar reflectance and thermal emittance properties, significantly reducing cooling loads and helping buildings meet stringent energy performance targets.
Compliance-Driven Roofing Solutions for 2024
Several roofing technologies are proving essential for meeting Arizona’s updated energy efficiency standards:
- TPO and PVC Membranes: Roofs that have reflectivities such as white TPO, PVC, and Elastomeric Coatings are the best. These single-ply membranes offer excellent reflective properties and are increasingly specified for commercial applications.
- Metal Roofing Systems: Metal would not be a good choice because it gets so hot when it sits out in the sun – but that is exactly why it works so well. The surface of the metal that is exposed to the sun is super-hot because it is reflecting all of that light. Underneath the metal, however, remains relatively cool because the heat has been reflected away.
- Enhanced Insulation Systems: Most commercial buildings have metal roofing substrates, then the roofing company will install insulation (ISO) on top of the metal with a single-ply membrane such as Firestone 60mil TPO, or Duro-Last PVC.
Local Expertise Matters for Compliance Success
Navigating Arizona’s complex energy efficiency requirements requires working with experienced local contractors who understand both the technical specifications and regulatory landscape.

Financial Incentives and Long-Term Benefits
Arizona offers several financial incentives for energy-efficient building improvements. Building owners who increase energy efficiency in building systems by at least 25% may be able to claim a tax deduction. Additionally, Arizona offers a property tax exemption for energy-efficient building components, making roofing upgrades more financially attractive.
The long-term benefits extend beyond compliance. Homeowners benefit from cost savings over time through reduced energy consumption and lower utility bills. Energy-efficient homes often boast higher property values and are more attractive in the real estate market. These advantages apply equally to commercial properties, where energy-efficient roofing systems can significantly impact operating costs and property valuations.
Looking Ahead: Preparing for Future Standards
On Sept. 16, 2024, the U.S. Department of Energy (DOE) announced $90 million in competitive awards to help states, cities, tribal nations, and their partners implement updated energy codes for residential and commercial buildings. These awards will support 25 new projects across the country to help ensure buildings meet the latest standards for energy efficiency—lowering energy bills for American families and businesses while reducing harmful greenhouse gas emissions.
City of Tucson (Tucson, Arizona) will leverage the Resilient Southwest Building Code Collaborative to facilitate a statewide workforce development and training program to ensure the successful implementation of resilient and efficient codes throughout Arizona. This federal investment indicates that energy efficiency standards will continue evolving, making proactive roofing upgrades a smart investment for commercial property owners.
As Arizona continues to refine its energy efficiency requirements, commercial property owners who invest in compliant roofing systems today will be well-positioned for future regulatory changes while immediately benefiting from reduced energy costs and improved building performance. The key is working with experienced local contractors who understand both current compliance requirements and emerging industry trends.
