was lower when compared with the average
office building in Malaysia. However, we believe
that JKR Complex still has the potential to
achieve an energy-efficient office building BEI
if saving measures proposed in this article are
implemented.
The breakdown of the overall energy
consumption of the buildings shown in Figure 5
above shows the highest (66.14%) was consumed
by the air-conditioning and ventilation system
and the second highest was the internal lighting
(21.53%) followed by office equipments and
domestic usage (7.5%) and the elevators (3.65%).
Energy Saving Measures
The recommended energy saving measures, ‘with
cost’ and ‘without cost’, in mid-year 2016 until
June 2017, to reduce the existing BEI of 127 kWh/
m 2 /year, are shown in the two tables below.
After the ‘without cost’ cost-saving measures
have been taken and those in item 2 of the ‘with
cost’ section have been made, the BEI readings
of JKR Complex may be reduced from a BEI 127
reading to an even lower BEI reading if the cost
savings for items 1 and 3 in the ‘with cost’ section
are executed.
In June 2017, the JKR Building Maintenance
Facility Branch in collaboration with the Building
Sector Energy Efficiency Project (BSEEP)
agreed to carry out item no. 4 - to install the
Online Monitoring System. The objective of this
installation is to monitor the energy consumption
of each block at the JKR Complex and to provide
