Building services refer to all the systems inside a building that make it functional for occupants. They include HVAC, plumbing, electrical, fire protection, transportation, lighting, and more. Building services are essential for providing thermal comfort, sanitation, power and communications. The architect's role is to design and plan these mechanical, electrical and plumbing systems to allow buildings to operate safely and comfortably. Proper planning of building services is important as they require significant floor and ceiling space. Without services, a building would just be an empty shell that cannot support living or working.

 The primary function of buildings is to provide shelter to its occupants.
WHAT IS A BUILDING?
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.

WHAT ARE SERVICES?
WHAT IS A BUILDING?
A building must do what it was designed to do - not just provide shelter 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'.

Building services are mainly divided into:
They are all very important part of planning, designing and construction of a building.

14.  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
Storage, Piping, Pressure Regulation & Supply of gas from its container to 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

 TRANSPORTATION:
Elevators, escalators, moving walkways/ travelators, parking, etc.
 LIGHTING:
Interior, exterior, emergency light.
 AUXILIARY:
Telephone, data, audio and video sound

16. 6.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 OR DESIGNER ?
 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.
