Are You Getting What You Paid For?
The intent of these various codes has evolved over time. In the beginning, there was a focus on safety, especially in the electrical trades to react to an ever-increasing knowledge of the dangers inherent in these systems. As technology advanced and the manufacturers saw a market opportunity, the codes have made an effort, sometimes prematurely, to implement this technology in the name of safety but also to include energy-efficient design components.
There is an argument to be made that the code should not include requirements beyond personal safety. In reality, the building permit procedure, which is almost always overseen by a local municipality, will continue to desire their infrastructures to be safe and energy efficient.
The design team has many considerations during project development that will lead them to include materials and systems that exceed the minimum standards established by the codes. The industry standards which parallel and perhaps enhance the code-requirements are just a start. The owner will have specific requests that often far exceed the basics. The desire for a green building will involve implementation of equipment and processes that will exceed minimal safety concerns, leading the designer to consider the longevity and efficiency of the specified products and systems.
The local authority or a third-party inspector will review your project at various stages of construction, but they will limit their review to the minimal standards of the code. A periodic review by the design team will ensure that the higher standards and requirements of the contract are completed as designed and that the owner receives a final product that aligns with their financial investment.
