Abstract
- Environmental Performance of Ceiling Systems in Building Construction – Currently used Systems and Future Optimisation Potenzial The building industry counts to the most influencing sectors regarding raw material demand, energy use and solid waste generation (≥ 38 %). The development and use of construction methods and building materials with minimal environmental impact over the entire life cycle has therefore utmost relevance. In order to quantify the environmental impact of construction methods and materials, a fact‐based life cycle assessment must be carried out. Currently, these kinds of assessments are not state of practice with a lack of objective comparisons missing on the market. When looking at building construction, ceiling systems in particular have a great influence on the environmental footprint of the entire building. Therefore, this paper is dedicated to the environmental comparison of different ceiling systems in building construction based on EN 15804 and EN 15978. The system boundaries were defined with the life cycle phases of cradle‐to‐gate and cradle‐to‐grave. A total of nine different ceiling types within different structural systems were considered and evaluated. All systems were dimensioned as efficiently as possible according to common engineering practice for the given boundary conditions with the currently valid standards (ÖNORM, Eurocode). The results show that environmental competitive systems can be implemented using all considered materials. The key is to take the materials properties into account while simultaneously optimising the structure and load‐bearing systems. [ABSTRACT FROM AUTHOR]
