UNIVERSITY MALAYA MEDICAL CENTRE (UMMC)ENERGY AUDIT REPORT

EXECUTIVE SUMMARY

INTRODUCTION

2.1. Background

Energy audits for govemment buildings are initiated by the Ministry of EnergyWater and Communication (MEWC) in response to the Prime Minister's directive on10% energy saving in Government Buildings. In order to irnplement the energysaving measures to the buildings, it is necessary to measure the energy consumptionand also the environmental conditions of the buildings. Therefore, an integrated andmulti-disciplirury approach energy audit has been conducted.

The client of this project is the Ministry of Energy, Water and Communication(MEWC).

Consultant

The consultant for this energy audit study is USAINS Holding Sdn. Bhd. The energyaudit team members are as follows:

BUILDING PROFILE

3.1 Site Description

University Malaya Medical Centre (UMMC) is one of the organisations in theMinistry of Higher Education. Main objectives of UMMC are health services,learning and research. UMMC is situated in the south-west comer of Kuala Lumpur,the dynamic and bustling capital city of Malaysia. It was officially opened on 5thAugust 1968. UMMC has since expanded rapidly from its original sole tower andancillary blocks to a medical complex that provides modern medical care for Klang

DRAFT

There was a 159/o increase in energy consumption in 2005 which according to the PTJSumber Perkhidmatan, was due to the completion of the Trauma and Kecemasanbuilding and began lts 24/7 operations.

Ner-ertheless, this was a significant increase compared to the following years of 2006

and 2007 u'hich showed a reduction of 2% and 0.1% respectively. Despite the slightreduclion, the electricity charges was on the rise due to the increase in electricitytariff in 2006.

3,2,2 Electrical Consumption for the Last 12 months (August 2007 - ]uly 2008)

The electrical consumption averages about 3,750,000 k\Afh per month as shown inGraph 3.2.
