Course Description: AEC Daily: Moisture Management & Sustainable Rainscreen Wall Systems
Rain control is a critical aspect of building envelope construction, affecting a building’s structural integrity and occupant health. This course presents the rainscreen wall system as an effective strategy for moisture management, as reflected in the WELL Building Standard™ version 2. Discussed are the fundamentals of moisture control in buildings, the history of rainscreens, rainscreen design principles, and cladding material selection, including potential contributions to credit achievement in the LEED® v5 Building Design and Construction (BD+C) rating system.
Recall how moisture moves through the building envelope and identify potential moisture management issues that can compromise a building’s appearance and structural integrity, as well as occupant health, comfort, and safety.
Explain how the components of a rainscreen wall system manage moisture to enhance building envelope durability and performance while supporting a healthier indoor environment, aligning with WELL v2.
Describe the sustainable advantages of a rainscreen cladding system in terms of structural integrity, moisture management, and energy efficiency.
Compare the aesthetics, durability, moisture resistance, and sustainable aspects of cladding materials and discuss how some products may support the requirements of LEED v5 BD+C.
