Energy Saving Measures
The recommended energy saving measures, ‘with
cost’ and ‘without cost’, are in the two tables below.
The BEI readings of Ministry of Works Complex
has decreased since the year 2016 after the cost
saving measures were made during the year. In
2017, some cost saving proposals are being made
including the electrical scope of items 1 to 3 and
the mechanical scope of items 1 to 3. Provision
of these retrofit works has been funded by the
Ministry of Energy, Green Technology and Water
(KeTTHA) at a cost of RM5.86 million.
