INTRODUCTION

Green building is the development and application of products, equipment and
systems used to conserve the natural environment and resources, which
minimizes and reduces the negative impact of human activities. Besides, The
Green Building Index (GBI) is Malaysia’s industry recognized green rating tool
for buildings to promote sustainability in the built environment and raise
awareness among Developers, Architects, Engineers, Planners, Designers,
Contractors and the Public about environmental issues and our responsibility to
the future generations. Meanwhile, GBI is developed specifically for the
Malaysian-tropical climate, environmental and developmental context, cultural
and social needs. Subsequently, advantages of green building is to save energy
and protect the environment using green technology. Lastly, to build the
environment that could reduce its negative environmental impact.

MENARA KERJA RAYA – KUALA LUMPUR
TYPE AND FUNCTION OF THIS BUILDING

This building was completed in 2015, this 37-Storey high rise government owned and
occupied Menara Kerja Raya recently became only the 2nd new building, in the non-
residential category to be awarded the prestigious Green Building Index (GBI) Platinum final
certification. The other building being Energy Commission’s Diamond Building in Putrajaya.
Standing at approximately 175meters tall, this tower houses a total of 1,600 staff from the
Ministry of Works as well as Public Works Department (Jabatan Kerja Raya) Malaysia over
53,000 square meters of building floor area. The offices of the Minister of Works as well as
the Director General and Deputy Director General of the Public Works Department have also
been moved to this tower.
Achieving GBI Platinum final certification is no simple feat for any building. The building
incorporates many features to reduce energy consumption, improve occupant comfort, reduce
impact of material usage as well as make use of less treated potable water.

Although the tower design incorporates floor to ceiling glazed facades which are exposed to
the East & West orientations, it manages to reduce solar heat gain by employing triple pane
insulated low-E glazing. Coupled with efficient lighting design with a low 8W/m2 lighting
power density and automated control which effectively turns of 40% of the office lights
during daytime, as well as air conditioning system that is able to reduce fan power down by
more than 50% on reduced load days, the building achieves a very respectable BEI (Building
Energy Intensity) of about 90kWH/m2year, which is about 60% lower than buildings that are
design to merely meet MS 1525 guidelines. This saves the Government approximately
RM2.5mil per year in electricity charges at the current energy rates.

Overall daylighting strategy played a huge role in creating a unique and much comfortable
indoor environment in this building. Custom perforated venetian blinds, low height
workstation and glass partitions for private offices and discussion rooms all work together to
create an open well daylit office space that is so much more inviting and conducive to the
occupants. With these strategies, we have verified that usable daylight levels are achieved up
to 6meters from the façade, which allows the automatic shut off of lights over these areas.

This tower is also one of the first building to incorporate a waste water treatment system that
is able to treat the greywater from wash basins, floor traps and ablution to be reused within
the building for toilet flushing and landscape irrigation. A 400 cubic meter underground
rainwater harvesting tank captures plenty of rainwater to be used for similar purposes in the
building when there is rainfall. These strategies and the use of low flow fixtures at toilets and
ablution, as well as significantly lower cooling load resulting in lower cooling tower water
usage has managed to reduce water consumption per square meter floor area by 70%
compared to another neighbouring JKR office tower.

Menara Kerja Raya was officially launched on the 7th of December 2016 by then Prime
Minister Datuk Seri Najib Tun Razak.

CONCLUSION

In conclusion, I can learn and know more about green building or green
technology. In addition, I was able to find out that there are many advantages to
green building. Furthermore, there are many green buildings in Malaysia and
this matter has received good and high recognition beyond my expectations.
however, green building in the country does not get high attraction probably
because many people still do not know about the existence of green building in
malaysia. therefore, the government needs to take action to introduce more
about green building in our country because it has many advantages for
example, it can reduce the living budget cheaper and save.
