Cain CAD provides compliance verification services for the International Energy Conservation Code (IECC), including state and local amended versions. The IECC code is a set of model codes established by the International Code Council (ICC) to regulate the energy efficiency of buildings.

The IECC provides guidelines and standards for the design, construction, and renovation of residential and commercial structures, aiming to reduce energy consumption, minimize environmental impact, and enhance occupant comfort. It covers various aspects of building design and construction, including insulation, lighting, heating, cooling, ventilation, and renewable energy systems. The IECC is regularly updated to reflect advancements in energy-efficient technologies and practices, and it serves as a basis for building codes adopted and enforced by local jurisdictions.

IECC compliance consists of the following three options: a prescriptive path, performance path, and an energy rating index path. All three paths also require third party inspection and testing of the envelope air barrier and insulation.
