Previously, designers commonly attempted to use a combination of the component and cladding provisions and other provisions in the Standard to determine these loads, often resulting in unconservative designs. CPD's new International Energy Conservation Code (IECC) checklist is designed to support project teams in navigating complexities of the IECC section of Denvers 2019 Building and Fire Code, and succeeding in delivering projects that support our communitys expressed priorities. Thus, these provisions are not applicable to open structures because the flow of the wind over the roof of enclosed structures and open structures varies significantly.
