Abstract

Data-based numerical tool for the Life Cycle Assessment of calcium silicate products. In the present work, the development of a data-based numerical tool for the standardized life cycle assessment of calcium silicate products is described. The Calcium Silicate Sustainability Label Tool (KS-NGS Tool) implements the methodology according to DIN EN ISO 14040/44 and DIN EN 15804 and enables the calculation of 31 environmental indicators, including global warming potential and primary energy demand. It forms the methodological basis of the Calcium Silicate Sustainability Label (KS-NGS) and establishes a binding framework for integrating ecological performance parameters into declarations of performance. The numerical tool is characterized by a modular architecture, user-oriented input of material and energy flows, as well as comprehensive functions for the evaluation and clear visualization of results. Thus, the tool not only represents a key milestone on the path towards a climate-neutral calcium silicate industry but also serves as a supporting instrument for the ecological and economic optimization of calcium silicate plants. The developed numerical tool is not limited to the calcium silicate industry but can, in principle, be transferred to other areas of the construction materials industry, thereby offering broad application potential for the ecological assessment of various construction products.
