The summary of the results of a comprehensive study on the comparative life cycle assessment of hall construction variants was presented at the Future Forum of the Hot Dip Galvanizing Industry Association.
The study compares four construction methods - hot-dip galvanized steel, wet-coated steel, reinforced concrete and wood - in terms of their environmental impact over the entire life cycle. It shows that hot-dip galvanized steel structures emit 30 percent lessCO2 than comparable wet-coated load-bearing structures. The zinc coating applied during hot-dip galvanizing bonds permanently with the steel, protecting it from external influences. Lower cumulative energy consumption than with wet-coated steel structures and significantly reduced material costs for the foundation compared to reinforced concrete structures are the reasons why galvanized steel performs very well compared to its market competitors.
The comparison of type solutions for the supporting structures of halls in this study was carried out on the basis of the standardized life cycle assessment method according to DIN EN ISO 14040:2021-02 and DIN EN ISO 14044:2021-02. In a life cycle assessment, the entire life cycle of a product or product system and the associated potential ecological impacts are recorded as comprehensively as possible. In accordance with the requirements of DIN EN ISO 14040:2021-02 Section 7.3.2, a critical review of the life cycle assessment has been carried out by an independent panel of experts.
