2025 BES Session: Analysis, Design Iteration and Verification of Nonstandard Water Control Strategies for Steep Slopes (Ardashev, Ridgway)

Course Overview
This session was originally presented at the 2025 IIBEC Building Enclosure Symposium in St. Louis, Missouri.  This course includes the following components:

• recording of the live session
• a summative assessment consisting of 10 multiple-choice questions
• two surveys required to claim continuing education credit

Description

There are standardized approaches, codes, and best practices that can be referenced for the design of gutters on low-slope roofs; however, resources are limited for the design of nonstandard sloped gutter systems and water management. Using the remediation of an existing pavilion with sloped gutters as a case study, we will present an approach to the design, analysis, and performance verification of sloped gutter systems. This case study will provide tools and practical applications not only in the remediation and restoration of existing built-in and sloped gutters, but also for water control strategies of complicated roofs that may be derived from a growing trend of computational design in architecture without sacrificing long-term durability.
