This course focuses on risk & reliability aspects of architectural engineering, applied to design & performance of various building systems. Students will explore probabilistic analysis and reliability-based design principles for hydraulic systems (storm drainage, water distribution, sewage), HVAC systems (thermal loads, system reliability), electrical systems (load factors, redundancy), and structural systems (load combinations, vertical & lateral loads, performance expectations). Emphasis is placed on how uncertainty & variability are quantified in each system to ensure resilience, reliability, and performance. Prerequisite: Grade of C or better in AREN 3301, AREN 3315, AREN 3346, AREN 4331, and AREN 4347 and admission to the AREN Professional Program.
