3 According to Singapore Power Ltd, the national average consumption was 4,590 kWh per 4-room household yearly consumption in 2014.

Energy Consumption
The operation andmaintenance of buildings require a considerable
amount of energy and related costs. With any increase in energy
consumption, carbon emission also rises in tandem. Therefore,
the Manager constantly looks into implementing various
initiatives and measures to lower energy consumption, carbon
footprint as well as operating costs. A summary of the energy
savings, achieved as a result of such initiatives, is detailed below
in comparison to total energy consumption.

Singapore
In FY14/15, the aggregated energy consumption at A-REIT’s
properties in Singapore increased by 7.1% to 99.4 million kWh.
This was mainly due to the increase in the number of reported
properties from 74 to 80. However, energy intensity achieved an

impressive reduction of 11.6% to 43.6 kWh/m
2
. This was well
above the reduction target of 5%, and was largely attributed to
the upgrading of the chiller plant, which led to improved energy
efficiency at Techlink, Techpoint, The Alpha and Cintech III. A
remarkable 2.3 million kWh of energy savings, equivalent to the
amount of electricity needed to power 501 four-room public
housing flats for one year
3
, was saved directly as a result.
Figure 7 charts the aggregate energy consumption, intensity,
as well as relative contribution by the various segments of
A-REIT’s Singapore portfolio. Consistent with the previous year,
Business & Science Park Properties was the most significant user
of energy, followed by High-Specifications Industrial Properties.

China
Compared to Singapore, the aggregated energy consumption
at A-REIT’s properties in China represents a fraction of the entire
portfolioat 5.2%(5.4million kWh) of total energy consumption. Over
a three-year period, the operations in Beijing achieved a consistent
decline of approximately 10.5% YoY in its energy consumption and
intensity of usage, owing largely to the optimisation of operating
strategies for air-conditioning. This included close monitoring of
room temperatures, adjustments of temperature setting upwards,
and reducing the operation hours of the air-conditioning during off-
peak hours. There was no change in the occupancy rate for A-REIT’s
property in Beijing during the three years.
FY14/15 was the second year of operation for the Business &
Science Park property in Shanghai. As a result of the increase
in average occupancy rate from 19.9% in FY13/14 to 44.3% in
FY14/15, the energy consumption and intensity of usage rose
by 24.9% to 1.7 million kWh and 15.7 kWh/m
2
respectively.
