Which of the following is NOT part of mechanical system requirements?

Environmental impact assessments are not typically considered part of mechanical system requirements. Mechanical system requirements generally focus on aspects that directly influence the performance, safety, and efficiency of mechanical systems within commercial buildings. These include installation practices, which ensure that systems are installed correctly and align with codes and standards; operational efficiencies that assess how well the system performs in terms of energy and resource usage; and design specifications that outline the precise requirements for creating and implementing the system.

While understanding environmental impacts is essential for broader building assessments and sustainability initiatives, it does not fall under the direct requirements for the mechanical systems themselves. Instead, it addresses the larger context of how these systems interact with the environment, which, although important, is separate from the technical specifications and operational characteristics that govern mechanical systems.
