The use of continuous insulation (ci) for a warm wall design creates an opportunity to leverage newer energy code insulation requirements in a way that also improves the building’s moisture performance.
The author provides an overview of the 2018 International Energy Conservation Code (IECC), discusses how and why the requirements for the building enclosure have changed, and how the current code will impact design and construction. He explores how climate influences design, the need to control air and water in an enclosure assembly, and the rationale behind reducing the percentage of glass on façades.
High-performing commercial buildings are becoming popular because of evolving codes and stricter standards for occupant safety, comfort, and energy efficiency. One can achieve high-performing building envelopes by combining various cavity insulation solutions, such as foam sheathing and insulation behind brick, stucco, concrete, and other cladding systems.
An important function of the building envelope is noise mitigation. Mixed-use buildings offer the benefit of social activities adjacent to habitable units, but spaces such as restaurants and bars will often operate late into the night, and require the ability to generate higher noise levels.
