What do the requirements for mechanical systems encompass?

The requirements for mechanical systems primarily encompass design, installation, and operation. This comprehensive approach ensures that mechanical systems are not only properly engineered to meet the intended purpose but are also safely and effectively installed. The operational aspect ensures that once the systems are put into place, they function as intended and comply with applicable codes and standards.

In terms of design, regulations ensure that systems are designed with appropriate specifications and considerations for safety, efficiency, and functionality. For installation, these requirements dictate that systems are installed following code standards to ensure safety and reliability. Lastly, operational requirements focus on how these systems perform in real life, addressing any necessary operational practices that promote efficiency and safety.

While energy efficiency benchmarks and maintenance procedures might play critical roles within specific contexts, they are subsets of the broader requirements associated with mechanical systems. Cost estimates and budgeting, while important for project planning, do not directly relate to the physical and functional aspects of mechanical systems as dictated by regulations and codes. Thus, the most comprehensive answer reflecting the full scope of requirements for mechanical systems is indeed focused on their design, installation, and operation.
