Malaysia's Energy Efficiency and Conservation Act 2024: what building owners should be checking

The Energy Efficiency and Conservation Act 2024 [Act 861] came into operation on 1 January 2025 and repealed the 2008 electrical energy regulations. It applies to Peninsular Malaysia and the Federal Territory of Labuan. Here is what is settled, and what you need to confirm for your own building.

Energy efficiency

kW/RT: why your chiller efficiency and your plant efficiency are different numbers

kW/RT is the standard measure of chilled water plant efficiency, but the figure on the chiller nameplate excludes pumps and cooling towers. Confusing the two is the most common reason a plant underperforms its design intent.

District cooling

How district cooling billing actually works: energy transfer stations, RTh and the meter in between

In a district cooling scheme the building does not own chillers — it buys cooling energy through an energy transfer station, measured in refrigeration ton-hours by a billing meter. Understanding that boundary is what determines who carries which risk.

Project delivery

Replacing a chiller plant in a building that cannot be switched off

Most chiller replacements in Malaysia happen in occupied buildings. The engineering is the easy part — the hard part is sequencing, temporary cooling and getting plant through a door that was sized for the plant you are removing.

Power & high voltage

What a 33 kV consumer intake actually involves

Large developments in Malaysia take supply at high voltage through a TNB intake substation and a consumer substation. The engineering is well understood; the programme risk sits almost entirely in the approvals and the land.
