Kecekapan Tenaga (KT)

• Penggunaan tenaga yang cekap yang biasanya dinamakan Kecekapan Tenaga (KT) bermakna menggunakan tenaga dengan bijak dan secara produktif bagi menyempurnakan tugas yang sama.

• Strategi tenaga ke-5 ialah dengan mempromosikan kecekapan penggunaan tenaga terutama dalam sektor perniagaan/perdagangan dan perindustrian.

• Malaysia boleh mencapai penjimatan satu pertiga daripada penggunaan tenaga tahunannya melalui usaha yang telah dilaksanakan dengan jayanya, seperti Projek Peningkatan Kecekapan Tenaga Industri Malaysia (MIEEIP).

What is Energy Management?

“Energy Management is part of the company’s management activities that control the energy use situation in the company, to ensure efficient exploitation of the energy to provide cost-saving without impairing normal building functions or occupant comfort and productivity”.

What is an Energy Audit?

The detailed Energy Audit involves in-depth investigations into identifications of :

1. How the energy in an organisation is currently consumed.

2. Various Energy Saving Measures (ESMs).

3. Costs and Simple Payback Periods for all recommended ESMs.

BUILDING ENERGY INDICES

• Are indices of energy performance of building/end-use energy.

• Can be in the form of:-– Building Energy Index– Lighting energy index– Air-conditioning energy index

• Unit:-– KWh/sq.m/yr.

• Total energy cinsumption a year devided by floor area.

• Total end-use energy consumption a year devided by floor area.
