Separation of Server Room
Overview for Office Unit
Whenever possible, it is worth placing server equipment in a small, partitioned room for noise management and
optimising operating conditions. The continuous operation of server equipment generates unwanted noise in the
workplace. In addition, server equipment requires strict control on temperature, humidity and water detection. Setting
up a small server room can be of benefit to server operations and create a quiet working environment. Furthermore,
isolation of the server equipment can avoid dust. IT equipment in a dusty environment will burn out components much
more frequently than one whose environment is relatively clean. A dedicated server room also offers the ability to secure
IT equipment against casual theft or tampering.
Benefits of Green Office Unit
A dedicated server room with a
separate air conditioning system can
greatly improve the efficiency of the
office air conditioning system.
A separate server room also helps
to provide flexible control of the air
conditioning system and therefore
improves air conditioning efficiency.
Green Strategies for Office Unit
z
Raise the floors in server rooms
to facilitate the distribution
of cool air, electrical power,
telephone/data cables and
water for room cooling units
z
E n s u r e p r o p e r c a b l e
management for proper
ventilation
z
Use the hot/cold aisle principle.
Hot-cold aisle configuration
in the rack space allows the
separation of hot and cold air
flows to maximise efficiency
of the cooling system. Cold air
is delivered to hot equipment
and hot air is returned most
efficiently to the Computer
Room Air Conditioning Unit
(CRAC) for cooling
z
Develop micro-cooling zones in
larger server rooms to allow the
precise amount of cooling to be
delivered to where it is needed

Benefits for Office Building
The IAQ Certification Scheme helps
to recognise good IAQ management
practices. Through participating in
the Certification Scheme, an office
building owner’s efforts in providing
environment with a good IAQ will be
publicly recognised. Furthermore, the
competitiveness of the building in
attracting tenants will be increased.
Benefits for Office Unit
It provides a good and healthy indoor
environment for staff, improves
productivity and minimises medical
expenses by reducing sick leave and
absenteeism due to poor indoor air
quality. The corporate image is also
enhanced.

Indoor Air Quality Certification
Scheme
Overview
The Indoor Air Quality (IAQ) Certification Scheme is a voluntary
programme launched by the Environmental Protection Department and
is managed by the IAQ Information Centre. This scheme is applicable to
the buildings or totally enclosed areas used as offices or public places
which are served by mechanical ventilation and air conditioning systems.
Up to June 2015, according to the list of certified premises from the
Environmental Protection Department, there were 216,240 buildings that
have obtained the Excellent Class IAQ certificate, while 806,920 buildings
have obtained the Good Class IAQ certificate. The increasing number
of IAQ certificates reflects the greater awareness by the public towards
good indoor air quality.
