Mechanical, electrical, plumbing and fire protection engineers focus on commercial buildings and the engineered systems within them
Commercial building insights
- When specifying systems into commercial buildings, engineers must consider the building’s use and the owner’s project requirements.
- Commercial building design must refer to a variety of codes and standards from organizations like ASHRAE or NFPA.
A commercial building is a type of facility that is used for the purpose of conducting business or other commercial activities. This can include office buildings, schools and educational facilities, retail stores, warehouses, industrial buildings and factories and other structures that are used to produce, distribute or sell goods or services.
Commercial buildings are typically larger and more complex than residential buildings, and they often have more specialized features and amenities to meet the needs of the businesses that operate within them. Some examples of commercial buildings include data centers, multi-dwelling buildings like dormitories and mission critical facilities.
According to the HVAC Equipment & Building Automation/Control Systems study, for example, the nonresidential building types the audience spend the most time designing included office buildings, government and military buildings and college/university buildings.
Mechanical, electrical, plumbing, fire protection, lighting and other engineers specify various systems into these commercial buildings, such as the HVAC, power, fire suppression or lighting systems.
There are several specialized nonresidential buildings that fall into this category, like mission critical facilities, medtail (medical retail) facilities and entertainment venues.

What are the engineered systems in a commercial building?
Engineered systems are critical components of commercial buildings that provide essential services such as heating, cooling, ventilation, lighting, power and fire protection. The specific systems used in a commercial building will depend on the specific needs of the building and its occupants. Some common engineered systems for commercial buildings include:
- Heating, ventilation and air conditioning (HVAC): These systems provide heating, cooling and ventilation to maintain a comfortable indoor environment. They may include boilers, chillers, air handlers and ductwork.
- Electrical: These systems provide power to the building and may include generators, transformers, switchgear and distribution panels.
- Plumbing: These systems provide hot and cold water, drain and waste management to the building. They may include water heaters, pumps and pipes.
- Lighting: These systems provide light to the building and may include fixtures, controls and dimming systems.
- Fire protection: These systems are designed to detect, notify and suppress fires in the building. They may include fire alarms, sprinkler systems and fire extinguishers.
- Security: These systems provide protection to the building and its occupants from intrusion and may include CCTV, access control and intrusion detection.
- Communication: These systems provide voice and data communication to the building and may include telephone systems, data networks and audio-visual systems.
- Building automation systems (BAS): These systems control and monitor the various building systems, including HVAC, lighting, security and fire protection, to optimize energy efficiency and comfort.
All these systems work together to create a safe, comfortable and energy efficient building environment. Engineers, architects and contractors must design and install these systems with the necessary expertise and knowledge to ensure the building's safety and performance over time.

What is an MEP engineer?
MEP stands for mechanical, electrical and plumbing. Other building engineering specialites include fire protection, lighting and technology. An MEP engineer is an engineer who specializes in designing, installing and maintaining the mechanical, electrical and plumbing systems in commercial and residential buildings. These systems include HVAC, plumbing, electrical power, lighting, fire protection and building automation systems.
MEP engineers work closely with architects and other building design professionals to ensure that the mechanical, electrical and plumbing systems in a building are integrated and work together effectively. They also work with contractors during the construction phase to ensure that the systems are properly installed and comply with all relevant codes and regulations.
MEP engineers are responsible for designing and specifying the equipment, materials and systems that will be used in the building, as well as the layout and routing of ducts, pipes and electrical systems. They also perform load calculations to determine the size and capacity of the systems and conduct energy analysis to ensure that the systems are energy efficient.
-
Is HVAC part of MEP?
Yes, heating, ventilation and air conditioning (HVAC) is considered a part of the broader field of MEP (nechanical, electrical and plumbing) engineering. HVAC systems are responsible for providing heating, cooling and ventilation to commercial and residential buildings to maintain a comfortable indoor environment.
MEP engineers are responsible for designing, installing and maintaining the mechanical, electrical and plumbing systems in buildings and HVAC is considered a major component of the mechanical systems within a building. Therefore, MEP engineers who work on HVAC systems are responsible for designing and specifying the equipment, materials and systems that will be used in the building, as well as the layout and routing of ducts, pipes and electrical systems, to ensure the efficient operation of the HVAC systems and the comfort of building occupants.
MEP engineers must also have a thorough understanding of building codes and regulations, as well as safety and accessibility requirements related to HVAC systems. They must also be able to work effectively in a team environment and communicate effectively with clients, architects, contractors and other stakeholders to ensure the HVAC systems are designed and installed correctly.
