Energy efficiency is no longer optional in New Zealand’s construction landscape, especially for multi-residential buildings. With the tightening of H1 requirements, architects and developers must consider better thermal performance and Building Code compliance. This post covers the key aspects of H1 compliance, how UNO Windows & Doors' Thermal Suites can support your project, and how UNO Hub makes accessing project-specific construction R-values easier.
Understanding the H1 requirements
H1 requirements under the New Zealand Building Code focus on energy efficiency, covering aspects like insulation, glazing, and heating. As of recent updates, stricter standards now apply, particularly in the thermal performance of windows, doors, and other external elements.
With their scale and complexity, multi-residential buildings present unique challenges in meeting these standards. Compliance is essential to ensure comfortable living spaces and reduced energy consumption.

Why H1 compliance matters for Multi-Residential projects
Meeting H1 standards isn’t just about ticking boxes; it’s about ensuring long-term energy efficiency and occupant comfort. For architects and developers working on multi-residential projects, non-compliance can result in costly delays, redesigns, and council approval issues. Choosing materials and systems that align with H1 calculations is critical to avoiding setbacks and ensuring smoother project delivery.
UNO Windows & Doors: Supporting H1 compliance with Thermal Suites
UNO Windows & Doors has developed thermal suites designed specifically to meet the demands of H1 energy efficiency requirements. Here’s how we help architects and developers streamline compliance for multi-residential projects:
Advanced Thermal Performance
Our thermal suite features a larger thermal strip, providing excellent insulation that helps achieve a higher construction R-Value. This translates into lower energy consumption and a more sustainable building environment. Our aluminium windows and residential doors boast high R-values, ensuring superior energy efficiency.

Control of the Supply Chain
Efficient End-to-End Solutions
Our proven processes support efficiency at every stage, from product selection through to final delivery. UNO's adaptable approach means we work closely with your project timeline and specific requirements, with clear communication throughout.
Compliance with NZ Building Codes
We provide documentation to support compliance with New Zealand Building Code requirements, including H1, helping project teams progress through the building consent process with the information they need.
How Thermal Suites impact Multi-Residential projects
Using UNO’s thermal suites not only ensures H1 compliance but also offers additional benefits:
Enhanced Property Value
Energy-efficient windows are a key selling point for multi-residential properties. They contribute to lower energy costs for occupants and a more comfortable living environment, which can increase the appeal and value of the property.
Sustainable Design
Architects and developers are increasingly prioritizing sustainability. With UNO’s thermal suites, you’re investing in products that support a more sustainable future through reduced energy consumption and greater durability.
Higher R-Value
For developers that are considering the value of money, a higher R-Value, gives you the ability to optimise all H1 requirements for the build, and creates potential savings in other insulation areas such as the roof or floor by utilizing the UNO Thermal Suite and the Calculation Method.

Supporting Architects and Developers with H1 Calculations
At UNO, we understand the complexity of H1 calculations and the importance of accurate construction R-values.
Through UNO Hub, architects can enter the windows and doors for their project and generate project-specific construction R-values based on the actual sizes, configurations and products being specified. These values can then be used within the Calculation Method as part of the wider H1 assessment.
Once the joinery specification is finalised, an R-value certificate can also be requested through UNO Hub to support building consent.
