Benefits for Office Building
Good indoor air quality is good
business. Good indoor air quality
management can reduce costs,
improve a building’s performance, and
avoid potentially expensive building
remediation.

Benefits for Office Unit
Poor indoor air quality has an adverse
effect on occupants’ health. Improved
indoor air quality can result in higher
productivity, fewer lost work days and
better business.
Green Strategies for Office Unit
z
Avoid the use of materials with
high concentration of pollutants
and volatile organic compounds
(VOCs)
z
Protect air duct system during
construction process or use a
temporary by pass ventilation
system to minimise the dust
pollution
z
Specify the use of less harmful/
low-emitting materials
z
Ensure adequate ventilation to
remove air contaminants
z
Isolate areas of work to prevent
contamination of clean/occu-
pied spaces
z
Perform air duct cleaning
z
Provide local exhaust systems for
polluting activities like redecora-
tion and printing
z
Install air purifier
z
Avoid unnecessary partitioning
of the premises and ensure
sufficient fresh air supply after
partitioning
z
Properly store all foods and
dispose of trash promptly to
prevent odours in offices
z
Clean upwater spills and remove
mouldy materials immediately
Indoor Air Quality
Overview
Indoor air quality has a significant effect on indoor environmental quality
and can have serious health effects on occupants over time. Sources of
indoor air pollution include natural sources, building materials, products,
and occupants’ activities. The common indoor air pollutants include (i)
chemical pollutants, (ii) particles, and (iii) biological contaminants.
The intent of improving indoor air quality is to reduce human health risks
by reducing exposure to indoor air contaminants, which can be done by
avoiding the use of materials with high concentration of pollutants and
volatile organic compounds (VOCs) and improving ventilation.

Measurement approach
To conduct measurements in interior spaces to demonstrate that total
volatile organic compounds (TVOCs),
(HCHO), carbon
monoxide (CO), nitrogen dioxide (NO

), respirable suspended particulate
(RSP) and ozone (O

) comply with the Good Class requirements
prescribed in the IAQ Certification Scheme.

Smoke-free Environment
ICC strictly complies with the Smoking
(Public Health) Ordinance (Cap.371)
and has joined the “Smoke free
charter” to practice smoke-free living
and actively promote a smoke-free
world.
Vertical Green for Looks and Air
Our Green walls in lobbies on Levels
3 and 9 are to refresh the air quality
of the area and to reduce dust and
volatile organic substances.
Measures to contain dust and other
harmful substances
Regular pre-occupation meetings are
conducted with incoming tenants and
their contractors. The work that is
conducted on the premises and that
will potentially contaminate indoor air
can thus be contained.

Inspection of fitting out units
Our staff will inspect renovating
premises regularly to ensure that all
work conducted in the building is in
compliance with the highest indoor air
quality standard.
Regular cleaning of air ducting and
filtering system
Air ducts and air filters of
are regularly sterilised
and cleaned to maintain excellent
indoor air quality.
