The project “Execution of Energy Efficiency Initiatives in 9 State-Owned Buildings in Melaka” project is an initiative by Melaka State Government initiated by State Economic Planning Unit (UPEN) and is managed by Melaka Green Technology Corporation (MGTC). The finance of project and retrofit work was carried out by Danish Energy Efficiency Partners Sdn. Bhd. There are nine buildings under this initiative and were audited in 2014. The retrofit works of three of them, namely Putra Specialist Hospital, Wisma Negeri and Melaka Sentra have been completed in 2016. The total project value is about MYR18.5 million.

Melaka Sentral Bus Terminal was commissioned in 2003. The building functions primarily as a bus and taxi terminal, connecting psassengers to inter-state and domestic destinations. The operational hours of the building are from 07:00 am to 10:00 pm. The gross floor area of the building is 20,000 m2, and almost all of it are air-conditioned. The baseline monthly average energy consumption was about 302,000 kWh.

The building was facing issues with inadequate indoor cooling and frequent malfunction of cooling and other auxiliary equipment. The retrofitting works were completed focusing on the upgrading of water-cooled package units and cooling towers system, and replacement of fluorescent lamps to LED lamps.

The project has successfully reduced about 634,000 kWh/ year, which is equivalent to 18% of the building energy consumption, and the indoor comfort level has been significantly improved.
