Static vs Dynamic EPDs: Why Project Specific Data Matters in Sustainable Construction

Sustainability is no longer an optional add-on in the construction industry. Clients, architects, and main contractors are all under increasing pressure to demonstrate the environmental performance of their buildings. At the heart of this is the Environmental Product Declaration (EPD), an independently verified document that communicates the environmental impact of a project.

But not all EPDs are created equal. Understanding the difference between static and dynamic EPD's is essential, particularly for fabricators and system houses committed to supporting transparency and supporting more sustainable building outcomes.

What is a Static EPD?

A static EPD is based on generic data, typically using industry averages. These documents provide a baseline environmental profile of a product, showing factors like embodied carbon and lifecycle performance.

For aluminium building systems, a static EPD might show the environmental impact of a door or facade system using standardised sizes and figures for material composition, transport distances, and manufacturing processes.

While valuable, static EPD's don't reflect the unique product and material choices of a specific project.

What is a Dynamic EPD?

A dynamic EPD goes a step further. Instead of relying on industry averages, it's tailored to a particular project, factoring in actual material quantities, specific transport distances, chosen finishes, and other project-driven variables.

This approach gives clients and building owners a much clearer and accurate picture of the true environmental footprint of their projects. For architects and main contractors, it means being able to provide more reliable data for sustainability reporting and certification schemes such as BREEAM, LEED, or RIBA 2030 Climate Challenge targets.

Generating Dynamic EPDs with TechDesign

For TECHNAL fabricators, dynamic EPDs are made possible through TechDesign - TECHNAL's advanced specification and design tool.

By using TechDesign during the project design and quotation phase, fabricators can generate a project-specific EPD. This process draws directly in the detailed information entered into the system, including product configuration, dimensions, material use, finishes, and glazing options.

This means sustainability data is embedded seamlessly into the workflow, saving time and ensuring accuracy. Fabricators can provide clients, architects, and contractors with transparent and reliable environmental data from the outset of a project.

Why Dynamic EPDs Matter

Offering dynamic EPDs through TechDesign can set fabricators apart in a competitive environment. They can:

• Support client sustainability goals with transparent, accurate, project-level data.

• Win new business by demonstrating advanced sustainability capabilities.

• Strengthen partnerships with architects and contractors who depend on precise data for certification.

As a systems house, TECHNAL is uniquely positioned to equip our fabricators with the right tools and data. TechDesign doesn't just streamline design, pricing, and ordering but also empowers partners to deliver project-specific EPDs that demonstrate a shared commitment to circular construction, resource efficiency, and carbon reduction across the entire value chain and building lifecycle.

Looking Ahead

As sustainability expectations grow, the construction industry will increasingly rely on project-specific data to demonstrate accountability. Static EPDs provide a starting point, but dynamic EPDs generated through TechDesign offer clarity, accuracy, and credibility.

By embracing this approach, fabricators, alongside TECHNAL, can lead the way delivering solutions that truly reflect the environmental impact of each building project. For clients, architects, and main contractors, that means greater confidence in sustainability reporting and a stronger foundation for responsible construction.
