Tall Building Services and MEPs
Tall Building Services
Tall building services are systems installed in tall buildings to improve their convenience, usability, productivity, and security. They include things like plumbing, lighting, ventilation, heating, air conditioning, fire safety, and information technology(IT) among others.
Types of Tall Building Services
For better understanding of building services, we’ve compiled a list of some of the major building services. They are:
Lighting
The word “lighting” refers to equipment that produces light as its primary function. Lighting can also refer to the use of natural light to provide illumination in tall buildings.
Lighting Protection
Through the provision of a low-resistance path to the ground for the lightning to travel along and dissipate, a lightning protection system (LPS) can shield a structure from harm brought on by being struck by lightning. Examples are ground rods and conductor cables.
Refrigeration
They serve as cooling systems for tall buildings. Examples are fans and air conditioners.
Alarm systems and security
In addition to maintaining the physical security of the property, it's critical to safeguard the tools, personnel, guests, and data. On building sites, security can be a significant factor. Some examples are; CCTV systems, intruder alarms and fire detection systems.
Escalators and Lifts
Escalators are machines that move people up and down between floors of a structure. They typically assume the shape of a moving staircase, comprised of a "chain" of single-piece stainless steel or aluminum steps that are moved by a network of tracks in an endless loop.
A lift (also known as an elevator) is a means of vertical transit between building floors, levels, or decks; it is frequently employed in workplaces, public spaces, and other multi-story structures. For people in wheelchairs as well as other non-ambulant building users, as well as for the vertical transfer of goods, lifts can be crucial for providing air flow, especially in tall buildings. Some elevators could also be utilized for evacuation and firefighting operations.
Fire Safety Equipments
Buildings must be planned to minimize heat and smoke dangers while providing an appropriate level of fire protection. Building services might provide a significant risk of ignite. Kitchens, plant rooms, and other structures should be placed where the threat from them is least. Some examples of fire safety equipment’s include smoke alarms, heat alarms and multifloor sensors.
HVAC( Heating, Ventilation and Air-Conditioning)
They are used to regulate air quality, temperature and humidity in tall buildings.
Plumbing and Water Drainage Systems
Any system that permits the transportation of fluids is referred to as plumbing. This system often contains valves, controls, water pipes, tanks, and other equipment. Plumbing systems function in waste removal, water supply, recovery and treatment as well as heating and cooling of water.
ICT systems
Information and communications technology (ICT) refers to tools and technologies that can be used for data storage, retrieval, transmission, and manipulation in addition to communication.
Systems for bacterial and humidity control, specialized lighting and security, emergency power, specialized gas distribution, fume cabinets, operating rooms, and other features are examples of specialist building services.
Importance of Tall Building Services
Building services are an important part of a building's design, influencing factors such as sizes, façade engineering, weights, and locations of major equipment’s and plants, the positioning of vertical service risers, as well as the routes taken for horizontal service distribution, energy sources and many others.
Building services engineers have a significant impact on a building's architecture, sustainability, and energy consumption, as well as its occupants' safety and well-being.
MEPs in Tall Building Construction
The systems that allow building interiors to be suitable for human use and habitation are covered by the three technical disciplines of mechanical, electrical, and plumbing engineering, or MEP. MEP systems turn plain rooms into warm, welcoming environments.
MEP installations are usually treated as a single unit due to their interdependence; this also avoids equipment location conflicts, which have been a common issue when MEP systems are built independently.
Components of MEPs
The three technical fields of mechanical, electrical, and plumbing engineering, or MEP, include the systems that make building interiors suitable for occupant usage.
Mechanical Engineering
Mechanical systems of various types are utilized in residential, commercial, as well as building industries. However, three(3) types account for the majority of mechanical design work in commercial buildings, and they are as follows; air-conditioning, space heating and mechanical ventilation.
These systems work together to maintain temperature and humidity levels that are cozy for occupants. Mechanical ventilation, in particular, makes sure that there is enough supply of fresh air to maintain pollution level at low and safe limits.
When the equipment capacity is sufficient, these mechanical installations function at their peak. There is a false notion that excessive engineering is advantageous. However, big boilers and chillers have a propensity to cycle quickly, resulting in a fluctuating room temperature and hastened equipment deterioration.
The inadequate regulation of indoor humidity is partly a result of over-engineering. To make such places ideal for human habitation, relative humidity should be maintained between 30% and 60%. Long-term humidity levels outside of this range can cause irritation of the skin and lungs due to low humidity, while high humidity encourages the growth of mold and germs.
In mechanical design, the best paths for heat-distribution systems including air ducts, hydronic piping, and steam piping are also laid out. If combustion appliances are employed, as is frequently the case (as we previously discussed when MEP systems are planned in isolation), then these appliances must be adequately vented to guarantee that dangerous combustion products are removed.
Electrical Engineering
Choosing the best conduit and wiring pathways is one of the more difficult electrical design tasks when building a multi-story, high-rise structure. In spite of this, electrical systems are typically more adaptable
than mechanical ones because they take up much less room and can more readily be routed around obstructions. Additionally, MEP software program can be helpful in this area because it enables conduit and wire to be set out with the shortest possible circuit lengths and without interfering with mechanical as well as plumbing installations by moving them out of the way.
Many MEP design software programs have lighting simulation capabilities that make it possible to identify the optimal amount of units and their positions for lighting systems.
Electrical and mechanical engineers work hand in hand together on HVAC (heating, ventilation, as well as air conditioning) design as part of the MEP process. In order to assess the capacity of the equipment, the first calculates the heating and cooling loads, while the second designs the electrical circuits and safety features that enable equipment to run constantly and safely.
Plumbing Engineering
In plumbing, MEP design software is used to streamline the process of drawing out complicated piping routes. Furthermore, it highlights how crucial it is for design teams to work together because plumbing installations frequently interact with mechanical and electrical systems.
High-rise structures, for instance, frequently require electric water booster pumps. As for residential hot water systems, they can be heated by a boiler, a heat exchanger coupled to a space heating boiler, or maybe an electric heater.
Importance of MEPs in Tall Buildings
Construction of Sustainable Buildings
Every field is developing tools for sustainable development, which has become a catchphrase. The MEP designs’ ability to act as a foundation for environmentally friendly building is one of their benefits. The development of the trend toward energy-efficient buildings depends on the MEP plans.
MEP designs apply efficient frameworks for lowering carbon dioxide emissions in the case of commercial buildings, where greenhouse gases are more prevalent. Additionally, the MEP plumbing engineering plans to guarantee that water is maintained and electricity is preserved.
Provision of Adequate Ventilation
MEP plans can be helpful in directing the flow of fresh air into buildings and removing impurities from them. One goal of adopting MEP designs is to control the ventilation, air conditioning, as well as space heating systems.
Proper Electrical Wiring
Laying electrical lines can be difficult in high-rise buildings, which highlights the value of MEP planning for vertical buildings. The MEP designs’ electrical component aids in navigating the buildings’ wiring and helps prevent electrical risks.
The uncontrolled and haphazard electrical systems in the structures are one of the factors contributing to urban building fires. By using this method, mechanical installations and electrical components can be separated. MEP plans can thus serve as a means of assuring safety.
Ease of Building Maintenance
An MEP design makes it simple to locate a building defect that is simple to correct because it reflects the mechanical, electrical, and plumbing systems of the structures.
This improves the efficiency of the entire construction process, which is beneficial in a variety of ways. A defective component can be quickly located and repaired, as opposed to needing to disassemble every component for repair.
Importance of MEP Engineers In Tall Building Projects
MEP engineers are helpful at every stage of the construction process, including the post-occupancy survey, schematic design, and management. Through a range of services, including building appraisal, system diagnostics, feasibility studies, as well as lease consultancy services, they are crucial to the process and can help maximize investment.
Conclusion
MEP services are almost always necessary when the three domains of MEP converge in their formulation and construction. Building automation, a service that combines all facets of MEP engineering, is growing in popularity. It enables centralized hardware and software networks to control HVAC, fire alarms, security, indoor and outdoor lighting, and a plethora of other operational processes that are essential for the efficient operation of buildings. MEP experts assist in reducing delays, misunderstandings, revisions, and redrafting throughout the early phases of a construction project.
The project is significantly streamlined once a company is able to manage all three MEP facets, giving it access to knowledge that can help save overhead and make the most use of your funds.
