TAVINOX at Brno University of TechnologyPractical experience with LCA and EPD as part of specialist teaching

On 3 November 2026, a specialist presentation entitled "Product life cycle, LCA and ESG: theory and a practical example" took place at the Faculty of Electrical Engineering and Communication (FEKT) of Brno University of Technology.

The presentation was prepared and given by Bc. Michal Hink, who, at CZECH STYLE, spol. s r.o., is involved in developing TAVINOX brand products and in coordinating the related technical and environmental documentation.

As part of the Production Ecology course (Ekologie výroby), the presentation introduced the basic principles of product life cycle assessment (LCA), type III environmental declarations (EPDs) and their use in ESG. The theoretical part was complemented by practical insights from the project to prepare two independently verified EPDs for TAVINOX stainless steel construction products.

From technical parameters to environmental data

When construction products are chosen, their technical properties, safety, service life and the economics of installation have traditionally played a decisive role. Increasingly important, however, is the ability to document the environmental impacts of the materials used in a transparent way.

The Life Cycle Assessment (LCA) method makes it possible to evaluate the potential impacts of a product at the individual stages of its life cycle – from raw material extraction through manufacturing and transport to the handling of the product at the end of its life.

Building on the LCA results is the Environmental Product Declaration (EPD). It is a standardised document based on defined rules and independent verification.

The quality of the input data, correctly defining the boundaries of the assessment and interpreting the results responsibly were among the main topics of the presentation.

TAVINOX as a practical example

The practical part drew on experience of coordinating the preparation of environmental declarations for two product groups:

Both declarations were prepared in accordance with the relevant international and European standards, in particular ISO 14025 and EN 15804+A2, and verified by an independent third party, Technický a zkušební ústav stavební Praha (the Czech technical and test institute for construction).

The presentation outlined the individual steps of the whole process – from defining the product groups and gathering the supporting documentation, through the expert preparation of the LCA, to independent verification and registration of the EPDs.

4. 4Independent verification and registration of the EPDs

Expert insights from practice in a university setting

Linking academic teaching with concrete experience from technical and business practice makes it possible to show that product life cycle assessment is not merely a theoretical discipline.

Obtaining a high-quality EPD requires not only an expert calculation model but also systematic coordination, rigorous work with the input data, a transparent methodology and independent verification of the results.

At the same time, the presentation showed how experience from a real industrial project can be used for educational purposes without disclosing internal manufacturing, commercial or contractual information.

Transparency as part of the further development of TAVINOX

At CZECH STYLE, we see high-quality technical documentation, independent verification and the availability of environmental data as an important part of the long-term development of the TAVINOX brand.

The registered EPDs are a further specialist resource for designers, investors, contractors and other partners who, when choosing pipework systems, take into account the environmental characteristics of products alongside their technical parameters.

Presenting practical experience with LCA and EPDs at Brno University of Technology is an example of knowledge transfer from industrial practice to the academic environment.

We believe that it is precisely this combination of technical development, verifiable data and specialist education that contributes to better-informed decisions in the design and installation of MEP (building services) systems.
