Energy efficiency has become the cornerstone of modern building design, particularly in commercial and high-rise residential construction. ANSI/ASHRAE/IES Standard 90.1 provides the framework for these energy-efficient practices by setting minimum energy performance requirements for contractors.
Builders looking to meet these standards can rely on Rmax polyiso insulation which provides superior thermal performance and ensures compliance with ASHRAE 90.1.
The Impact of ASHRAE 90.1 on Energy Efficiency
Adherence to ANSI/ASHRAE/IES 90.1 is about more than following a set of guidelines—it directly influences a building’s energy consumption and operational costs. The standard governs key areas like insulation, HVAC systems, lighting, and service water heating.
By ensuring compliance, contractors reduce energy consumption and operational costs, while also enhancing environmental sustainability. This is particularly critical in regions with extreme temperature fluctuations, where inefficient insulation can lead to higher energy use and costs.
Building Systems Governed by ASHRAE 90.1
Building Envelope
A well-insulated building envelope is central to minimizing thermal transfer. Rmax polyiso insulation, with its superior R-values per inch, helps contractors meet ASHRAE's U-factor and solar heat gain coefficient (SHGC) limits, to ensure compliance with stringent energy standards.
HVAC Systems
The standard sets detailed efficiency requirements for HVAC systems. Pairing HVAC systems with Rmax’s polyiso insulation reduces thermal loss and improves overall system efficiency, to minimize energy demand.
Lighting
The standard also requires energy-efficient lighting systems, such as daylight-responsive controls and LED lighting. Proper insulation maintains stable indoor temperatures that complement these systems and further enhance building performance.
While these requirements form the foundation of ASHRAE 90.1, contractors must also stay informed about recent updates and how they affect building design and energy performance.
Recent ASHRAE 90.1 Updates Every Contractor Should Know
The 2019 and 2022 editions introduced a range of updates designed to improve energy efficiency across commercial and high-rise residential buildings. These updates have significant implications for HVAC systems, building envelopes, and energy recovery.
Increased HVAC Efficiency Requirements
New metrics such as COP_{HR}—which measures heat recovery in chiller systems—were introduced to raise HVAC efficiency standards across various building types. This emphasizes the need for better insulation to reduce HVAC demand.
Enhanced Building Envelope Requirements
Stricter U-factor and SHGC criteria were implemented, which increased the demand for high-performance insulation materials like Rmax polyiso.
Energy Recovery Systems
The latest updates mandate the use of energy recovery systems in HVAC configurations, which further highlight the importance of effective insulation to maintain stable indoor temperatures. These updates ensure energy performance is maintained across a building’s lifecycle.
ASHRAE 90.1 also provides flexibility for meeting compliance through the Performance Rating Method (Appendix G), which allows designers to exceed prescriptive requirements by trading off different building systems, such as HVAC and the building envelope.
With these updates in mind, Rmax polyiso insulation offers a high-performance solution that ensures contractors can meet ASHRAE 90.1 standards efficiently.
How Rmax Polyiso Insulation Ensures ASHRAE 90.1 Compliance
To meet the stringent requirements of ASHRAE 90.1, choosing high-performance insulation is essential. Rmax’s polyiso insulation delivers top-tier R-values, to help contractors comply with both prescriptive and performance-based compliance paths.
Advantages of Rmax Polyiso Insulation Include:
High R-value per Inch
Polyiso insulation provides excellent thermal resistance, which means less material is required to achieve high insulation levels. This reduces wall and roof thickness while also maintaining energy efficiency.
Air and Moisture Barrier Capabilities
The closed-cell structure of polyiso enhances moisture and air control, to help contractors meet air leakage and water resistance standards.
Sustainability and Environmental Impact
Polyiso aligns with broader sustainability goals, to support energy efficiency and reduce environmental impact. Contractors using Rmax products contribute to meeting both compliance standards and sustainability targets.

Best Practices for Contractors to Achieve ASHRAE 90.1 Compliance
To maximize energy efficiency and achieve ASHRAE 90.1 compliance, contractors should follow these best practices:
Continuous Insulation
Ensure continuous insulation across the building envelope, particularly around windows and doors, to minimize thermal bridging.
Air Sealing and Moisture Control
Install proper air barriers and vapor retarders in conjunction with Rmax polyiso insulation to meet air leakage requirements, to ensure long-term durability.
Comprehensive Compliance Documentation
Keep detailed records of insulation installations and energy performance metrics during the design and building phases. This is crucial for both prescriptive and performance-based compliance paths.
Implementing these strategies ensures compliance with ASHRAE 90.1 and provides long-term benefits to building owners, including reduced energy costs and improved indoor comfort.
