What does the IECC stand for?

The correct answer is International Energy Conservation Code, which is a model code that outlines minimum energy conservation standards for buildings. This code provides guidelines aimed at reducing energy consumption in residential and commercial buildings, ensuring that energy efficiency is prioritized in construction and renovation practices.

The IECC is crucial in setting benchmarks for effective energy use, helping architects, builders, and code officials implement standards that can also contribute to sustainability efforts. By adhering to the IECC, buildings can achieve improved energy performance, which not only lowers operational costs but also minimizes environmental impact.

The other choices do not accurately reflect the established code. For instance, Insulation Energy Compliance Code, Integrated Energy Conservation Corporation, and International Energy Certification Council do not exist as standardized frameworks or recognized institutions comparable to the IECC, making the correct answer all the more significant in the realm of energy efficiency in building practices.
