Facility Energy Analysis for ASMA Building, Bukit Jelutong

Date: 10/12/2009

Report No.: EE_01

1. Introduction

The purpose of this Facility Energy Analysis Report is to provide information about

how energy is used, and direction about potential energy savings opportunities forASMA Building facility. The analysis and recommendations are based upon the

information that was provided during the recent preliminary audit.

The accuracy of this analysis and the resulting recommendations are directly influencedby the degree of accuracy of the data that was provided. The analysis is intended to

provide guidance and focus on the greatest potential energy savings opportunities and

recommend next steps.

2. Energy Efficiency.

Energy use and thus, improvements in energy efficiency, can contribute to theachievement of long-term organizational objectives. Links between energy efficiency

and business objectives can be direct, as in the case of improved operational efficiencyand reduced costs, or indirect, such as with improved employee productivity. Listed

below are a few examples how energy efficiency can contribute to business success.

Examples of Business Objectives with Links to Energy Efficiency

Improved operational efficiency

Reduced operating costs Improved product quality

Improved air quality Improved tenant/occupant satisfaction

Improved employee productivity Improved contribution to environmental protection & sustainability

Improved company image

3. How ASMA Building Use Energy

Break-up of energy consumption (Estimation)

Air-Conditioning = 60% ; Lightings = 24%; Miscellaneous Equipments = 16%

From the recent preliminary audit, the air-conditioning system is a split type and the

lightings system majority use fluorescent type with conventional ballast.

This facility is found to be less efficient in energy management due to the type ofequipment used and non availability of facility automated monitoring and control system.

Air-conditioning system is not functioning at an efficient level.

The energy cost in your facility is around RM 21,500 per month base on the previous

three months bill. It is possible to achieve higher level of efficiency by implementingreadily available energy efficiency strategies and management practices but that will

require major refurbishment and new fit outs.

4. Energy Savings Opportunities

Significant energy savings can accrue from implementing a combination of best energy

management practices and upgrading or installing new, more energy efficient technology.The greatest potential savings opportunities for your facility are summarized below.

4.1 Low and No-Cost Opportunities

Energy savings up to 15 percent can be realized by adopting best energy managementpractices. These opportunities typically require little or no cost to implement. Suggested

best energy management practices for ASMA Building include the following:

Your Energy Saving Opportunities

Office Equipment:Turn off office equipment and appliances and invoke energy saving features. Computers,monitors, copiers, fax machines, and printers often have energy saving modes which are

not activated and most office equipment is left on unnecessarily.

Outdoor Air:Check that minimum outdoor air levels are at recommended requirements which maintain

proper indoor air quality; many buildings actually bring in much more outdoor air thannecessary.

Operation & Maintenance:Have mechanical systems checked and maintained on a regularly scheduled basis. Atleast 10% in energy savings may be expected for systems that are properly maintained

versus those which are serviced only when problems occur. Moreover, equipment life isprolonged, leading to further cost savings. Minimize the use of split unit cooling system.

Air-Conditioning Controls:

Have controls for air conditioning (split unit) equipment checked to ensure that they areoperating at optimum levels. Re-adjust the thermostat to 24 degree C and above.

Lighting:

Optimize circuits and/or energy management systems to only control areas where lightingis needed at desired times. Review the Lux level according to the required or

recommended optimum level.

4.2. Cost Based Savings -High Savings

Based on the energy profile for ASMA Building facility, the following energy efficiencymeasures represent the greatest potential for savings.

High Value Opportunities/Requires investment .

Opportunity Action Item

Air Conditioning Improve cooling system

effectiveness by reducingcooling system losses, routine

maintenance, and/or replacingthe existing split system with

VRV system will increase inoverall cooling efficiency.

Lighting Retrofit interior lighting withmore efficient system.

Energy Modelling Conduct energy modelling

analysis to simulate actualenergy consumption

5. Methodology

The Facility Energy Analysis has evaluated a number of energy saving measures that canbe taken immediately and others that will require additional information and planning.

The following steps are suggested:

Planning

Identify how energy efficiency improvements link to achievement of your business

objectives both directly and indirectly to create motivation for action Develop an energy efficiency improvement target for your business

Identify a person who will become the "energy manager" for your business Develop a detailed plan for how to achieve your target

Immediate No Cost/Low Cost Energy Savings Opportunities

Develop a plan to implement the suggestions from section 4.1 Develop an employee awareness and communications program to gain broadsupport and participation for your energy savings initiatives

Retrofit/Other Improvements

Conduct a cost/benefit analysis to determine if the project meets your

organization's investment criteria. Remember to take into account the influence of"cross effects" when evaluating the long-term benefits of your project.

More detailed information regarding reducing Energy/Utility service usage andcosts at your facility can be obtained through a Standard Audit (On-Site).

6. A Detailed Energy Audit

A detailed audit is a natural supplement to the preliminary audit, once it has beenestablished that a detail audit is necessary. The work on site during a detail audit usually

takes from week to months and is concerned primarily with the energy consumption ofthe largest users and quantifying the potential savings. The components forming the

detailed audit include:

y Establishing how, when and at what efficiency energy is used by various electricaland mechanical systems in the building.

yEstablishing the cause of any cyclical tendencies.

y Identifying opportunities for energy saving potential, quantifying the saving and ifapplicable estimating the capital cost required to effect the saving.

7. On Site Measurements

Accurate, half-hourly measurements should be made of

y Energy consumption profile (kWh, KVA and Power Factor)y Internal climate conditionsy External climate conditionsy Air supply characteristics (temperature, pressure, humidity, volume)y Cold and hot water temperaturey Lighting energy consumption

8. Summary

The results of this Energy Audit Service for your facility as detailed in this Report showthere is a potential for energy cost savings if there is follow-up on the action items that

have been identified.

The energy cost breakdowns and potential savings indicated are based upon informationthat you provided. A number of factors, such as weather variations, building occupancy,

and operation schedules, can affect energy usage and, consequently, energy cost savings.Therefore, we cannot offer any assurance that the suggested energy-saving measures,

whether implemented individually or in combination, will necessarily result in realizingthe indicated, or any, energy cost savings.

9. Remark

In order to make the energy audit successful prior to achieve energy efficiency

program, the following information are very much required:y Actual/as-built building layout/drawingsy Actual/as-built schematic drawingsy Equipments inventory lists
