This study presents a comparative evaluation of the floor, wall, and core timber panel systems implemented in two representative mid-to-high-rise, panel-system-based timber buildings. Specifically, this study focuses on the structural performance, economic viability, fire resistance, serviceability, timber recycling, and overall material consumption. Based on the analysis results, alternative design strategies were proposed to enhance the overall performance of each building. The study found that replacing the CLT floor panels in Bridport House with prefabricated LVL-joist panels and substituting the concrete core of the Badenerstrasse Building with a CLT panel core would significantly improve performance. The comparative analysis framework developed in this research is intended to serve as a guideline for identifying optimal structural systems in the design of mid-to-high-rise timber buildings.
