BUILDING SERVICES SEMINAR

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)

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.

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.

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.

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.

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.

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

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.
