PERFORMANCE AND ENVIRONMENTAL IMPACT ANALYSIS OF RESIDENTIAL BUILDINGS: A COMPARATIVE STUDY

The study investigates and compares six different types of ten-story residential buildings, focusing on structural design, performance, and carbon emissions. Three buildings include slab and shear wall components, while the other three comprise structural frames, each designed differently with Cross Laminated Timber (CLT), Reinforced Concrete (RC), and hybrid systems. Through modeling in ETABS and adherence to Saudi Building Code (SBC), all buildings met strength and serviceability criteria. Notably, the CLT-based buildings displayed varied deflection characteristics compared to RC-based structures. Moreover, carbon emissions were assessed from manufacturing to construction stages, considering CLT and RC elements. The data, including material volumes and weights, were essential for emission calculations. Results indicated varying CO2 production levels based on specific materials used in construction. Additionally, the study involved a survey among construction companies to gather feedback on CLT utilization, aiming to further analyze industry perspectives. This comprehensive analysis sheds light on the structural and environmental aspects of diverse building types, offering an understanding of their performance and carbon footprint.
