A building must do more than provide shelter - it must provide a safe, comfortable, and livable environment. Building services make a building functional by providing necessities like air conditioning, ventilation, lighting, plumbing, electricity, safety and security systems. Properly planning and designing building services is important for sustainability and occupant well-being. As architects, we are responsible for integrating mechanical, electrical, and public health systems to allow buildings to operate safely and comfortably.

and you are left with a cold, dark, uninhabitable shell.
How will you feel????
For examples imagine yourself in your dream house or shopping mall
now take away the lighting, air-conditioning and ventilation, the lifts
and escalators, acoustics, plumbing, power supply and energy
management systems, the security and safety systems...
▪ Building should be designed in such a way to provide an
environment where people can feel comfortable, work, live and
achieve.
▪ Basically “BUILDING SERVICES” is what that makes a building
come to life i.e. what makes the building work.

but also provide a safe, comfortable & livable environment.
Building services contribute largely to the sustainability & functioning
of the building.
So, Everything inside a building which makes it safe and
comfortable, comes under the title of 'Building services'.

11. •Air conditioning and refrigeration
•Energy supply – gas and electricity
Building services include:
•Heating and ventilating
•Water supply – supply,
drainage and plumbing
•Lighting - Day lighting and artificial
lighting
•Escalators and lifts
•Harnessing solar, wind and biomass energy
•Communications, telephones and IT networks
•Security and alarm systems
•Fire detection and protection

12. Classification Of Building Services
Building services are mainly divided into:
They are all very important part of planning, designing and construction of
a building.
Mechanical Systems, Electrical Systems
And
Building Operation System.

13. •HVAC Systems:
stands for “heating, ventilating and air-conditioning” and includes a variety of
active mechanical/electrical systems to provide thermal control in buildings
Control of the thermal environment is a key objective for virtually all occupied
buildings. Better thermal comfort will influence occupant health, satisfaction and
productivity.
•Site Drainage: water, drainage, sanitary disposal,
Removal of waste water from kitchens, bathrooms, sinks, soil waste(toilet waste),
storm water management and surface runoff to local sewerage system.
•Gas Supply: cooking gas, commercial gas, oxygen & nitrogen gas in hospitals

required area.
•Plumbing: water distribution, water treatment, sanitary facilities.
Storage, distribution (piping), sanitary fixtures (taps, WC’s, showers, etc)
•Fire protection: water supply, water sprinklers, fire and smoke detection,
announcement.
Mechanical systems: Brief Introduction

14. •Electrical power:
Normal, standby, emergency power supply and distribution
•Transportation:
Elevators, escalators, moving walkways/ travelators, parking, etc.
•Lighting:
Interior, exterior, emergency light.
•Auxiliary:
Telephone, data, audio and video sound
Building operation systems:
•Processing:
Products, food service, etc.
•Automation:
Environmental controls, management, automated lighting,
automated parking, etc.
Electrical systems : Brief Introduction

15. Importance Of Building Services
•Building should be designed such that it provides 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.
•The implementation of services demands a considerable amount of
floor and ceiling so proper planning is necessary for their allocation.
What Is The Role Of An Architect ?
•Building services are indispensable for buildings.
•As an example certain types of building such as department store or
industrial buildings are almost 100% dependent on electrical lighting,
ventilating and air-conditioning and
•High rise buildings rely on vertical transportation and high speed
pressure for water supply.
•Responsible for the design and planning of the mechanical,
electrical and public health systems required for the safe,
comfortable and environmentally friendly operation of modern
buildings.
