Energy performance benchmarking for
buildings
● Gauge the potential in energy savings
● Energy Efficiency Index (EEI): total energy consumed per unit of gross floor
surface
● kWh / m2 / year
● Comparison by building category:
● Hospital, hotel, office, shopping mall, condominium, government buildings,
etc.
● Use the benchmarking tools to position your building accordingly

How to make your building green?
● Building & Construction Authority of Singapore
launched the Green Mark® certification scheme:
● Point-based assessment to rate buildings on their
environmental impact and performance
● Voluntary program for new and existing private
developments
● Objectives:
● Promote awareness and recognition
● Identify best practices in development, design,
construction, management and maintenance in
buildings

Green Mark Response
● More than 100 buildings have the Green Mark certification
● More than 60 of these buildings are residential developments, which
contains over 19,000 green homes.
● Millennium Residence receives Singapore BCA Green Mark Gold
Award (1st in Thailand)
● Owner of the building: MR Sukhumvit Co., Ltd.
● Harvesting of waste water and rain water to provide irrigation
● Carbon Monoxide Monitoring system for the underground parking facilities
to operate the fans only when needed

Case Study: Schneider Electric’s
industrial building in Bangpoo
Schneider Electric - Thailand – 09/2009
21
Demonstrating significant energy
savings in Schneider Electric’s buildings
In 2005, Schneider Electric
Thailand decided to
undertake an energy
reduction program in its
industrial building in
Bangpoo.
Schneider Electric - Thailand – 09/2009
22
First step to success: energy
consumption monitoring
● The basis of a successful energy efficiency program
is to implement an Energy Management System.
● PowerLogic® power monitors were installed at node
points to survey the electricity consumption.
● Real time data logging and reporting was made
through a specialized System Management Software.
Investment: 1.5 MTHB
Savings: 2 MTHB / year*
Payback: 9 months*
* During the first year of implementation
Schneider Electric - Thailand – 09/2009
23
Air-Conditioning Optimization and
Control
● Turn on period of the air-conditioning was
optimized in the buildings through control boxes
with integrated Programmable Logic Controllers.
● Over-sized A/C units were replaced as per actual
room requirements.
● Staff awareness promotion through strategic
communication was made.
Investment: 158.5 kTHB
Savings: 122.6 kTHB / year
Payback: 16 months
Schneider Electric - Thailand – 09/2009
24
Water Pump Control
● A Variable Speed Drive (VSD) was installed at
the cool water pump for the chiller system.
Investment: 167 kTHB
Savings: 57 kTHB / year
Payback: 2.9 years
Schneider Electric - Thailand – 09/2009
25
Cooling System Optimization
● Refrigerant in the air-conditioning was
replaced from R22 to hydrocarbon
which has a higher cooling capacity.
● An evaporative pre-cooling media was
integrated to the existing condensing
unit at the point of entry of the air.
● Preventive maintenance was
scheduled on the condensing units
according to the readings on the power
monitoring system.
Investment: 423.5 kTHB
Savings: 488.3 kTHB / year
Payback: 10 months
