Mechanical Building Services Engineer

Building services engineers are responsible for designing, installing, operating, and monitoring the mechanical and electrical areas of modern buildings. They ensure that the facilities are safe, comfortable, and environmentally friendly.
Mechanical building services engineers specialize in the design, development, construction, and operation of mechanical services, most especially the HVAC (Heating, ventilation, and Air Conditioning) system, plumbing and piping system, conveyance system, and fire suppression. In today’s world, mechanical building services engineers coordinate life safety systems such as medical gases and low-pressure gas systems.
The criteria and consideration for the design and selection of the various mechanical systems will be examined individually  in this piece to provide as accurate a result as possible.

HVAC

HVAC, in a word, is a sub-discipline of mechanical engineering based on the principle of thermodynamics, fluid mechanics, and heat transfer to provide thermal comfort and acceptable indoor air. Proper indoor air is equivalent to 20’C – 22’C (68’F – 72’F) temperature ranges, 15-20 CFM air qualities, and relative humidity of 20% – 60%.
H- Heating
Heating in HVAC is the process of providing warmth to a building or apartment by using mechanical equipment such as heat pumps, boilers, and condensing furnaces. The system also includes the low-energy (low temperature) Solutions.
V- Ventilation
Ventilation is the science of exchanging and circulating air in any space to provide high indoor air quality. The ventilation process also helps to remove unpleasant smells and excessive moisture by introducing outside air. The process can be of two ways: the natural method and the forced method.
The natural ventilation method involves the process of ventilating an apartment or building by using architectural features and solutions such as the building window, the doors, building vent, etc.
The forced ventilation method involves using mechanical forced equipment such as fans, exchangers, air handlers, etc.
Ventilation also includes cleanroom solutions, factory spaces, and processes.
AC- Air conditioning
Air conditioning is the process of cooling a building by using refrigerant, which is expressed in tonnage or British thermal units. This refrigerant is classified into chlorofluorocarbon compounds, hydrochlorofluorocarbon compounds, and hydrofluorocarbon. However, R-134A, which is a type of hydrofluorocarbon, is the only one predominantly used in the industry today.
AC equipment is of different categories, sizes, and types which will be broadly elaborated. Examples include Split Ac, multi-split Ac, etc.
HVAC Services also consider the site microclimate, the building form and orientation of spaces, the thermal performance, building characteristics, the occupancy trends, and restrictions on pollutant emissions.

Plumbing

The plumbing services provided by mechanical building services engineer includes the practice, materials, and fixtures used in the installation, maintenance, extension, and alteration of all piping, fixtures, appliances, and appurtenances in connection with any of the following system :

1- Internal network

– the domestic cold water system

– the domestic hot water system

– sanitary drainage and sewerage system

– venting system

2- external network

  • External water network
  • External drainage network
  • External stormwater network

3- Swimming pool

  • Types of swimming pool
  • Types of swimming pool pump
  • Swimming pool filtration system
  • Swimming pool pipes, inlets, and drain
  • Swimming pool equipment.

Services also include inventive solutions to sanitary drainage system design, domestic cold water system, domestic hot water system, storm system, and waste management system.

Suppression system

The suppression system is the most important and often the mandatory services provided by mechanical building services engineers because of its direct relation to human life and property. This branch of services uses the hydro-mechanical component to cease the fire outbreak. The system services (design and installation) must comply with all applicable National, State, and Local laws, codes, rules, and regulations.

The system can be simply divided into two;

Water suppression system which comprises of the sprinkler system, reel and cabinet systems, the fire department connections, hydrant system, etc.

Gaseous suppression system majorly focuses on the fire extinguisher, and the use of inert gases such as FM200, CO2.

Medical gas system

Medical gases system are services provided in hospitals and healthcare to supply specialized gases to various parts of the facility. The services provided by mechanical building services engineer includes the selection of appropriate medical gas system and equipment, determination of flow rate demand of the system, Piping and pipe sizing for medical gas, and controlling and alarm of the medical gas system.

The types of medical gas systems commonly use today include oxygen, nitrous oxide, nitrogen, carbon dioxide, medical air, etc.
