2. TYPES OF SERVICES IN BUILDINGS
• HVAC(Heating Ventilation & Air Conditioning)
• ELECTRICAL
Electrical wiring
Fire alarm
• PHE(Public Health Engineering)/PLUMBING
Sewerage
Waste management
Water management
Rain water management
• FIRE(Fire Fighting)

3. HVAC
• ‘HVAC’ refers to Heating Ventilation and Air
Conditioning, which can be used in buildings to:
• Maintain internal air quality.
• Regulate internal temperatures.
• Regulate internal humidity.
• It is sometimes extended to include refrigeration
(HVACR), heating, ventilating, air conditioning
and refrigeration.

4. Working Process Of HVAC
• Internal air quality can be maintained by a combination of introducing
‘fresh’ air into the building, extracting ‘stale air’ and by filtration.
Ventilation may be natural, mechanical, or mixed mode (a hybrid system).
See ventilation form more information.
• Internal temperatures can be regulated by heating and cooling. Typically
this is achieved by heated water (or sometimes steam) and chilled water
that is generated by boilers and chillers and then used in heating coils and
cooling coils as part of the ventilation system. Alternatively hot water may
be used to supply radiators.
• Humidity can be regulated by ventilation, dehumidification and
humidification. Dehumidification is often provided alongside cooling as
cooling air reduces the amount of moisture it is able to ‘hold’, resulting in
condensation and so dehumidification. 'Close' humidity control (to within
10%) can involve cooling and dehumidification, then re-heating and re-
humidification.
Very broadly, HVAC systems can be centralised in a
building, or local to the space they are serving, or a combination of both. They
may also be connected to a wider district heating or cooling network.

5. ELECTRICAL
• Electrical Services is composed of three units: Electrical, Electronic
Low Voltage, and High Voltage.
• The Electrical Unit maintains secondary voltage power distribution
systems, performing such maintenance functions as:
• Installation of new electrical circuits
• Repair of indoor and outdoor lighting systems.
• General troubleshooting and repair of electrical distribution
systems.
The Electronics and Low Voltage Unit installs and
maintains permanent systems such as fire alarms, clock, and bell
systems.

6. PLUMBING
• Plumbing is the system of pipes, drains, fittings, valves, and fixtures
installed for the distribution of potable water for drinking, heating
and washing, and waterborne waste removal. "Plumbing" also
refers to the skilled trade which installs and maintains it.
• The plumbing industry is a basic and substantial part of every
developed economy.[1] The word derives from the Latin plumbum
for lead, as the first effective pipes used in Roman era were lead
pipes.
• "Plumbing" often denotes the supply and waste system of an
individual building, distinguishing it from water supply and sewage
systems that serve a group of buildings.

7. PLUMBING SYSTEMS
• The major categories of plumbing systems or subsystems are:
• potable cold and hot tap water supply
• plumbing drainage venting
• sewage systems and septic systems with or without hot water heat
recycling and graywater recovery and treatment systems
• Rainwater, surface, and subsurface water drainage[relevant? –
discuss]
• fuel gas piping
• hydronics, ie heating and cooling systems utilizing water to
transport thermal energy, as in district heating systems, like for
example the New York City steam system.

8. FIRE PROTECTION SYSTEM
• Fire protection is the study and practice of
mitigating the unwanted effects of potentially
destructive fires.[1] It involves the study of the
behaviour, compartmentalisation, suppression
and investigation of fire and its related
emergencies, as well as the research and
development, production, testing and
application of mitigating systems

9. COMPONENTS
• Fire protection in land-based buildings, offshore construction or
onboard ships is typically achieved via all of the following:
• Passive fire protection - the installation of firewalls and fire rated
floor assemblies to form fire compartments intended to limit the
spread of fire, high temperatures, and smoke.
• Active fire protection - manual and automatic detection and
suppression of fires, such as fire sprinkler systems and (fire alarm)
systems.
• Education - the provision of information regarding passive and
active fire protection systems to building owners, operators,
occupants, and emergency personnel so that they have a working
understanding of the intent of these systems and how they perform
in the fire safety plan.
