Energy Saving
Annual reduction in energy use of the BEC
Headquarters is expected to be at least 20% based on
actual electricity billing/metering data. A reduction of
24.6% in energy consumption was recorded for the
period of July 2014 to September 2014.

Air conditioning control:
Offices and specialty room
occupancies (conference
rooms, kitchen, etc.) have
active controls capable
of sensing space use and
modulating the HVAC system
in response to demand from
different areas.

Reducing Water use
Overview
Most of the water consumption in an office building results from hand
washing and toilet flushing. Water saving sanitary fitments are available
from the market. Owner/tenants can purchase the water saving product
of WELS Grade 1 or WELS Grade 2 based on the recommendations of
the Voluntary Water Efficiency Labelling Scheme (WELS) from the WSD.
BEAM Plus BI V1.0 WU 2
The use of water efficient devices shall lead to an estimated aggregate
annual water saving of 30% when compared with BEAM Plus baseline.
BEAM Plus BI V1.0 WU 3
The flushing system installed within the project space should be water
efficient, lowering sewerage volume.
Water efficient flushing systems include, but are not limited to:
• Sensor type urinal
• Waterless urinal
• Flushing system certified by WELS Grade 1
• Dual flush water closet
Green Strategies for Office Building
Green Strategies for Office Unit
The Voluntary Water Efficiency
Labelling Scheme (WELS) is a
water conservation initiative
of the the Government. WELS
intends to cover the common
types of plumbing fixtures and
water-consuming appliances.
Products participating in
WELS will incorporate a
water efficiency label that
tells consumers the level of
water consumption and water
efficiency to help consumers
choose water efficient products
for water conservation. WELS
has been implemented in
phases for different categories
of plumbing fixtures and
appliances.
