CASE STUDY FACT SHEET
CASE STUDY FACT SHEET
Energizing Kowloon East Office
Artificial Lighting:
•
integrated with
task lights effectively reduce the
lighting power density (LPD)
• Daylight and motion sensors were
installed to further save lighting
energy consumption when the
lighting is not required
Energy Efficiency:
• Variable refrigerant volume (VRV) air
conditioners were installed which
give energy efficiencies (above
3.8) much higher than room air
conditioners / split units (usually
below 3.0)
Water Management:
• Low-flow taps were installed at the
toilets and pantry
• Rainwater is harvested for irrigation
of the landscaped areas
Indoor Environmental Quality:
• Independent exhausts are also
provided for photocopiers to remove
the particulates at source
• Indoor air quality meets the Good
Class of the IAQ Certification Scheme
• The building is set back from the
street boundary by about 15m to
minimise traffic noise impact from
the abutting road
Ventilation:
• Ventilation system designed
to provide higher outdoor air
ventilation rates than the minimum
requirements by ASHRAE 62.1-2007
(ASHRAE, 2007) and to facilitate
dilution of indoor air pollutants
Construction Waste Reduction:
• Extensive use of prefabricated
building components such as the
freight containers and mild steel
framing structures help minimise
construction waste
• Most of the construction waste
including wood, rebar and concrete
were reused or recycled
Construction Noise and Pollution
Control:
• Off-site fabrication
• Reduction of inter-phasing
Site Specific design for land saving:
• Revitalising a piece of unattractive
land on a site under the Kwun Tong
Bypass
