MEP stands for "Mechanical, Electrical, and Plumbing." It refers to the integrated systems that are essential for the functionality of buildings. These systems include heating, ventilation, air conditioning (HVAC), electrical wiring, and plumbing fixtures. Proper design and installation of MEP systems ensure that a building operates efficiently and safely. In construction and architecture, MEP engineers play a crucial role in planning and implementing these systems. They collaborate with architects and other professionals to create designs that meet building codes and energy efficiency standards. Effective MEP design contributes to the overall comfort and sustainability of a building.
