INGENIEUR
1. MINISTRY OF WORKS COMPLEX
Building Description
The KKR Complex building is located at Jalan
Tun Ismail, Kuala Lumpur. The building, which
was completed in 1996, serves as a Federal
Administration Office for the Ministry of Works
Malaysia (KKR). The building has three building
blocks, namely Block A (6 floors), Block B (14
floors) and Block C (3 storeys).
The whole area is as follows:
- Total area of the building Blocks
A-C: 41,843 m 2
- Spacious air-conditioned area in Blocks
A-C: 33,322 m 2
Data Collection
The data from all blocks in the complex was
collected from June 10-17, 2015. The overall
Index of energy consumption for the building is
shown in Table 1:-
Referring to Figure 1, the Building Energy
Intensity (BEI) of K KR Complex in 2014 was 12%
higher when compared with the average for office
buildings in Malaysia. However, we believe that

KKR Complex has the potential to achieve energy-
efficient office building BEI if the saving measures
proposed in this report are implemented.
The breakdown of the overall energy
consumption of the buildings in Figure 2 shows the
highest percentage (70.8%) was consumed by the
air-conditioning and ventilation systems and the
second highest (22.6%) was the internal lighting
followed by office equipment and domestic uses
(4.3%) and the elevators (1.2%).
Energy balance analysis was conducted to
ascertain and confirm the current consumption
rate of electricity during the audit by using a
power logger installed on the meter and making
comparisons with TNB’s electricity bill. The
average energy consumption of electricity per
month based on TNB’s electricity bill in the year
2014, was 597,058 kWh.
According to the Energy Audit data bill, the
difference in energy usage data is 7,743.64 kWh
monthly. This low 1.3% difference indicates that
the data obtained during the audit is reasonable
and acceptable (See Table 2).
