What are the two main types of loads present in MEP systems?

In MEP (Mechanical, Electrical, and Plumbing) systems, the two main types of loads present are static and dynamic loads. Static loads refer to forces that are constant or vary little over time, such as the weight of the structure, fixtures, and permanent equipment installed in the system. These loads are predictable and can be calculated based on the design specifications.

Dynamic loads, on the other hand, involve forces that vary over time and can change due to different factors such as movement, vibration, or changes in the operating conditions. Examples include fluctuating electrical loads in response to equipment operation or variations in airflow in HVAC systems as a result of occupancy changes or system control strategies.

Understanding the distinction between these types of loads is critical for engineers and designers in ensuring MEP systems are adequately sized, efficient, and compliant with safety standards.
