Sub Code: CT730 BUILDING SERVICES –I
1. INTRODUCTION
What is a Building?
A structure that has a roof and walls and stands permanently in one place. The primary function of
buildings is to provide shelter to its occupants.
What is Building Services?
 Building function cannot be limited to provide shelter only. Basically “Building Services” is what
that make the building comes to life. i.e. what makes the building work.
 Building should be designed in such a way to provide an environment where people can feel
comfortable, work, live and achieve.
 So, everything inside a building which makes it safe and comfortable, comes under the title of
“Building Services”
 A building must do what it was designed to do-not just provide shelter but also provide a safe,
comfortable and livable environment.
 Building services contribute largely to the sustainability and functioning of the building.
 Building services systems are essential provisions for a building, accounting for 20% to 40% of
the total construction cost. Figure 1 shows the cost breakdown of a typical government office
building.

Introduction
Building service is one of the important parts for a building because it will make a building to function
well. Building service is responsible for the design, installation, and operation and monitoring of the
mechanical, electrical and public health systems required for the safe, comfortable and environmentally
friendly operation of modern buildings. Modern technology of building service can make a building to
become more safety or more comfortable. While building developers are increasingly being asked to
analyze and improve building security, developing technologies assisting engineers in the pursuit of safe
working environments couldn't have better timing. Hence, innovation of new building service is important
so that the level of safety and comfortable can be increases. Building services influence the architecture of
a building and play a significant role on the sustainability and energy demand of a building. Within
building services engineering, new roles are emerging, for example in the areas of renewable energy,
sustainability, low carbon technologies and energy management. With buildings accounting for around
50% of all carbon emissions, building services engineers play a significant role in combating climate
change. As such, a typical building services engineer has a wide-ranging career path. Communication
lines, telephones and IT networks (ICT) also make an important role in building service, and the modern

technology for the ICT is fiber optics that makes use of fiber optics than normal internet cable, hence this
can hugely increases the speed of internet because fibers are used instead of metal wires because signals
travel along them with less loss and are also immune to electromagnetic interference. Fibers are also used
for illumination, and are wrapped in bundles so they can be used to carry images, thus allowing viewing
in tight spaces.
Building services include:
 HVAC
 Water supply
 Drainage and Plumbing
 Lighting-Day and Artificial
 Communications, Telephones and IT Networks
 Energy Supply- Gas, Electricity and renewable resources
 Automation
 Kitchen
 Acoustics
 Fire Detection and Protection
 Security and Alarm Systems
 Escalators and Lifts
 Ventilation and Refrigeration
 Harnessing Solar, Wind and Biomass energy
 Facade Engineering
Importance of Building Services:
 Today with the advancement of sciences and technology, all those building services listed above
are more modern and became indispensable for buildings.
 As an example certain types of building such as department store or industrial buildings are almost
100% dependent of electrical lighting, ventilating and space heating.
 High rise buildings rely on vertical transportation and high speed pressure for water supply.
 Although those services are indispensable for modern buildings, they also have an impact. In fact
the implementation of those services demands a considerable amount of floor and ceiling so

proper planning is necessary for their allocation. Increase of ceiling and floors will lead to an
increase of the cost of construction to which building construction team should be aware of. One
of the considerable impacts on building is the increase of energy consumption which does not only
affect the building but the environment as well.
 In fact designing, construction, operating and maintaining buildings demand a considerable
amount of energy, water and other resources which lead to a large amounts of waste.
 The complexity of mechanical and electrical systems varies according the living standard of the
society, the climatic conditions of the region and the occupancy and quality of the building.
Main objectives of BSE design
 Hygiene (prevent disease & ensure health)
 Safety (protect against risks)
 Comfort (physio- & psycho- well-beings)
 Convenience (efficiency & productivity)
Classification of Building Services:
Building should be design with features to provide better lighting, comfortable space, temperature and
air quality, convenient power and communication capability, high quality sanitation and reliable systems
for the protection of life and property. Building services are mainly divided into mechanical, electrical
and building operation systems. They are all very important and should be put into consideration during
planning, designing and construction of a building.
1. Mechanical systems include:
1- HVAC Systems: heating, ventilation and air conditioning.
2- Site drainage: water, drainage, sanitary disposal.
3- Plumbing: water distribution, water treatment, sanitary facilities.
4- Fire protection: water supply, stand pipe, fire and smoke detection, annunciation.
5- Gas supply

2. Electrical systems include:
1- Electrical power: normal, standby, emergency power supply and distribution.
2- Lighting: interior, exterior, emergency light.
3- Auxiliary: telephone, data, audio and video sound

Work activities
 Building services engineers design building services systems. They also supervise their
installation and operation. Certain types of buildings need complex building services. For
example, computer rooms need precise controls of temperature and humidity, hospital operating
theatres must be completely sterile and factories must prevent any harmful fumes from going into
the atmosphere. Office buildings, swimming pools, cold stores, museums and leisure centres also
have particular requirements that building services engineers need to meet.

 Some building services engineers are mainly office based as they specialise in design work. They
work closely with the architect, the customer and other members of the design team to prepare a
design for a building project. This includes all drawings and detailed specifications for use by the
contractor. They often use computer-aided design (CAD) packages for this work.
 Designs must meet environmental needs, use energy efficiently and meet the budget set by the
customer. Engineers need overall knowledge of the full range of building services, although they
usually specialise in either mechanical services or lighting/electrical services.
 Building services engineers maintain close links with other professionals such as the construction
manager and the surveyor to decide how many staff are needed and to work out costs. They
supervise the installation of the building services and inspect the quality of the work, dealing with
any problems that arise.
 BSE career opportunities also arise in the fields of Construction Project Management and
Facilities Management particularly in the area of modern industrial facilities involving clean room
manufacturing, such as in pharmaceutical and electronics production.
 Typical works of building services consulting firms include:
o Feasibility, inspection, technical reports, estimating
o Design, specification, drawings, tender procurement
o Contract management, site supervision, cost control
 Activities vary according to the specialist area of work and employer (for example, client/end-
user, building contractor or engineering consultancy). However, tasks typically involve:
o negotiating and developing project contracts and agreeing these with clients, if working in
consultancy, and putting out tenders;
o commissioning, organising and assessing the work of contractors;
o working with detailed diagrams, plans and drawings;
o using specialist computer-aided design (CAD) software and other resources to design the
systems required for the project;
o managing and forecasting spend, using whole life cycle costing techniques, ensuring that
work is kept to budget;
o designing site-specific equipment as required;
o overseeing and supervising the installation of building systems and specifying maintenance
and operating procedures;
o monitoring building systems and processes;

o making decisions about expired systems equipment and the appropriate location of new
equipment;
o facilities management;
o liaising closely with other professionals, including structural engineers, builders, architects
and surveyors, and in-house project teams;
o attending a range of project group and technical meetings;
o ensuring that the design and maintenance of building systems meets legislative and health
and safety requirements;
o advising clients and architects on energy use and conservation in a range of buildings and
sites, aiming to minimise the environmental impact and reduce the carbon footprint;
o working on a variety of projects within a short period of time.
Personal qualities and skills
 As a Building Services Engineer, you should be a good teamworker as you will work closely with
various construction professionals such as Architects, Quantity Surveyors and Structural
Engineers. You should also be a good communicator as you have to explain ideas and designs to
other members of the team. You also need a creative and enquiring mind and an ability to solve
problems.
 Building Services Engineers are concerned primarily with the progress of technology through
innovation, creativity and change. They develop and apply new technologies; promote advanced
designs and design methods; introduce new and more efficient production techniques and
marketing and construction concepts; and pioneer new engineering services and management
methods. They may be involved with the management and direction of high-risk and resource
intensive projects. Professional judgement is a key feature of their role, allied to the assumption of
responsibility for the direction of important tasks, including the profitable management of
industrial and commercial enterprises.
