| In the past year, we have sought to reduce our energy
consumption and enhance energy management by: |
 |
Adopting Energy Codes in our building designs. |
|
Fitting corridors and staircases in 17 estates
with photocell lighting controls so that lighting is switched
on when needed and reviewing our standard domestic block design
to incorporate these measures. We also ran a trial on photocell
control of outdoor lighting. |
|
Piloting a gas-fired dehumidifying air-conditioning
system in collaboration with Towngas. We are seeing energy savings
of about 30%. |
|
Enhancing energy efficiency in our car parks:
12 car parks were fitted with electronic ballast showing energy
savings of about 20%. |
|
Investigating energy efficiency measures for
air-conditioning in our headquarters (we are now planning retrofitting
works). |
|
Distributing 60 000 stickers reminding staff
and contractors to save energy such as by switching off lights. |

Despite the various measures we
have taken, our use of electricity has risen due to 3 factors:
firstly, newer residential building designs with illumination
levels enhanced for barrier-free access to common areas of buildings;
secondly, we are providing better facilities (such as air conditioning
in commercial centres and markets); and thirdly, our newer blocks
are taller and have a higher energy requirement for things such
as lifts and water pumps. As newer ones replace older buildings,
the electricity consumption has inevitably increased. Nevertheless,
our efficiency in electricity use is improving due to the measures
we are implementing, and as we take advantage of improved new
technology. |
|
Electricity consumption at our offices rose 6.9% in 2001/2002, because
our staff occupied the new office block at our headquarters. |
Hong Kong Energy Efficiency Registration
Scheme for Buildings
In the past year, we have achieved energy efficiency certification
for more of our building designs. This includes:
|
6 more standard domestic block designs certified
as complying with the Code of Practice for Energy Efficiency
for Lighting Installation and 2 for Electrical Installation. |
|
Registering 2 retro-fitted shopping centres
in the Scheme for lighting installation. We are also seeking
registration for another 4. |
|
 |
| The adoption of Energy Codes has resulted in an estimated
5% electricity saving for the domestic blocks tendered in 2001/2002
as compared with the design in 2000. |
