What is one of the key purposes of the Building Code Compendium's explanatory material?

The key purpose of the Building Code Compendium's explanatory material is to offer practicality and clarity in code understanding. This explanatory material is essential as it aids professionals within the construction and design industries, such as builders, architects, and engineers, in interpreting the complex regulations contained in the Building Code. By breaking down intricate code requirements and providing clear definitions, examples, and guidance, this material ensures that those involved in the construction process can adhere to safety standards, meet regulatory requirements, and ultimately ensure the integrity of the structures being built.

While other options might seem relevant in different contexts, such as critiquing trends or suggesting modifications, they do not align with the primary function of the explanatory material. The focus is on aiding comprehension and practical application of the Building Code, rather than providing entertainment or commentary on design trends.
