There are two major considerations with lighting systems for corridors and stairs, namely orientation and
safety. The right light in these areas therefore creates the perfect atmosphere in two ways. It helps guests
find their way around a building – and gives them a feeling of safety and comfort during their stay.
AC power plugs and sockets are devices that allow electrically operated equipment to be connected to
the primary alternating current (AC) power supply in a building. Electrical plugs and sockets differ in
voltage and current rating, shape, size and type of connectors.
HVAC
HVAC (heating, ventilation, and air conditioning) is the technology of indoor and vehicular environmental
comfort. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of
thermodynamics, fluid mechanics, and heat transfer.
HVAC is important in the design of medium to large
industrial and office buildings such as hotels, where safe
and healthy building conditions are regulated with respect
to temperature and humidity, using fresh air from
outdoors.
There are many different types of heating systems. Central
heating is often used in cool climates to heat houses and
public buildings. Such a system contains a boiler, furnace,
or heat pump to warm water, steam, or air in a central
location such as a furnace room in a home or a mechanical room in a large building. The use of water as
the heat transfer medium is known as hydronic. These systems also contain either duct work for forced
air systems or piping to distribute a heated fluid to radiators to transfer this heat to the air. The term
radiator in this context is misleading since most heat transfer from the heat exchanger is by convection,
not radiation. The radiators may be mounted on walls or installed within the floor to give floor heat.
