Introduction to Operation and Maintenance

Stage

MyCREST Operations & Maintenance Stage is a tool for the sustainable

implementation and assessment of the on-going operations and

maintenance of existing commercial and institutional buildings. The

certification system identifies and rewards current best practices for

sustainable operations and provides guidelines for reducing a building’s

use of energy, water, and natural resources; while at the same time

improving the indoor environment; lowering life cycle carbon emissions

and addresses operating inefficiencies.

The MyCREST Operations & Maintenance tool helps building owners to

implement minimum standards of sustainability in operations improve

building life cycle performance, and maintain and improve this

performance over time. It consequently reduces the cost of building

operations, reduces environmental impacts, creates a healthier indoor

environment and more productive employee workspaces, and

ultimately provides a community contribution and increasing public

recognition through ensuring sustainability.

For MyCREST Design and Construction Stage, the focus is largely on the

design, construction and major renovation phase of a building. When

the project is complete, and the building is in operation, the MyCREST

Design and Construction tools would have performed their intended

task. Operations & Maintenance Stage is intended to ensure that the

building continues to operate as intended a deliberate plan is created

providing high performance over time. The rating system captures both

a building’s physical systems (equipment, design, land use, etc.) and

7 | P a g e

the way the building is managed and operated by its managers (waste

management, temperature monitoring, commuting programs, etc.)

A key goal of MyCREST Operations & Maintenance Stage Certification

is to institutionalize a process of reporting, inspection and review of the

building’s performance over the lifespan of the building.

My CREST O&M tool is developed based on criteria related to practices

during building operation, which contribute towards reducing carbon

emissions and lowering a life cycle impact on the environment and

enhancing building performance through time. The tool is applicable

for both new buildings (That target for MyCREST carbon award) and

existing buildings.

MyCREST rating tool includes the operational criteria and practices AND

design and construction CRITERIA.

Those targeting higher star rating for the O& M stage must consider

either verifying or implementing design or construction strategies

through sub-criteria contained in the O&M scorecard.

Amongst others, these are:

1. Storm water Management

2. Landscape & Greenery

3. Urban Heat Island

4. Renewable Energy

5. Low VOC Materials

6. Passive and Active Design Features

8 | P a g e

Design and construction strategies can also park under Innovation

Points.

Re-Certification

The building can apply for re-certification at least once every 3 years to

maintain their MyCREST Operations & Maintenance status and the

building energy performance.

MyCREST Award Energy Performance (EP) Points in MyCREST O&M

Scoring

These are two ways as follows:

1. If the building is considered energy efficient, the Energy

Performance Impact scoring is based on achieved or

implemented of savings from the baseline, which defined as

current energy reading at the start of the performance period.

2. If the building is considered non-energy efficient-building

(Existing buildings that do not comply with MS1525 or ASHRAE

90.1 2007), the BAU reading is taken as the baseline.

ENERGY PERFORMANCE IMPACTS O&M EP Req9 Improving Energy Performance EP Req9 Cr

1. Energy Efficient Building Achieve or Maintain Verified Levels or Declared Energy Efficiency After Commissioning Process 2. Non-Energy Efficient Building Improved by 6% Energy Savings from Business as Usual (BAU)

Required

Aim

This is a mandatory criterion that the building owner/operator must

comply and achieve Energy Reduction for energy efficient building

and 6% reduction for non-energy efficient building from the business as

usual (BAU).

Requirement

REQUIRED:

1. Energy Efficient Building

Achieve or maintain verified levels or declared energy

efficiency after commissioning process.

2. Non-Energy Efficient Building

Improved by 6% Energy Savings from business as usual (BAU)

Justification

A building cannot be considered ‘green’ if it is not energy efficient. The

energy used by buildings mostly generated by burning fossil fuels, which

release greenhouse gas emissions that contribute to climate change.

No building should define itself as “green” unless it consumes less

energy and generates fewer greenhouse gas emissions than average.

34 | P a g e

Approach & Strategy

An existing building’s energy assessment will help identify areas of

building operations that are not operating efficiently. Implement

energy-saving operational and management practices and/or energy-

efficiency retrofits to reduce energy use to the level required to meet

this requirement.

The MyCREST rating system awards energy performance points based

on the building current energy consumption compared to a business as

usual levels.

However, any ‘Existing Building’ needs to be identified as an Energy

Efficient (EE) Building and a Non Energy Efficient Building in order to

identify the correct scoring EP tool to use:

The building is considered as Energy Efficient Building if it complies with

any of the criteria below:

1. Comply with the minimum requirement for OTTV, RTTV,

lighting and ACMV components and equipments under

item 5, 6, 7 and 8 as stated in MS 1525:2007

AND

Show a minimum of 6% energy reduction above the

business as usual of MyCREST.

OR

2. Comply with mandatory requirements of Appendix G

ASHRAE 90.1 2007.

OR

3. Comply with all relevant requirements in JKR’s EE need

statement.

OR

35 | P a g e

4. A certified Green building that has achieved a green

building final construction certification and has been fully

commissioned.

The carbon emission factor for electricity is taken as 0.747 kg

CO2e/unit(MGTC. (2011))

The Building In-Use

The Building Energy Consumption of the building in-use is the metered

or measured building energy consumption at the point of the initiation

of the building’s measurement period. The measurement methodology

can be referred to the International Performance Measurement &

Verification Protocol (IPMVP).

The IPMVP provides a “framework to determine energy and water

savings resulting from the implementation of an energy efficiency

program.” The framework provided by IPMVP has become the

industry’s standard for savings verification.

According to the IPMVP, it provides “an overview of current best

practice techniques available for verifying results of energy efficiency,

water efficiency, and renewable energy projects.” The IPMVP

addresses energy conservation measures that reduce energy through

the installation or retrofit of equipment or the modification of

operational procedures.

Large energy efficiency contracts should include at least some of the

elements recommended in the IPMVP. Often these contracts include a

savings guarantee that pays for part or all the costs of the project. The

IPMVP provides a very credible guidance to help the project auditor

verify that savings have occurred and how much has been realized.

36 | P a g e

There are four approaches to measuring savings that are termed as

“Options A, B, C, and D” in IPMVP. However, for MyCREST, only

methodologies in Option C and D will be used.

Options C (Whole facility) and D (Caliberated Simulation)

These options are used when the nature of the Energy Conservation

Measure (ECM) is not easily measured in isolation from the rest of the

building operations. This could be typical of operational and control

changes that affect many areas of the building.

The Option C approach assesses savings at the whole-facility level by

analyzing utility bills before and after the implementation of the ECM’s.

Option D uses computer simulations and modeling of the whole facility,

usually when base year energy data is not available or reliable.

Installation of energy management control systems (EMS) and

training/awareness programs are good examples for Option C.

Generally, Options C, and D involves much more time and skill to

conduct and, therefore, are going to be more costly to measure.

Existing Buildings (EB)

The underlying philosophy of this certification method is to allow

buildings that are already green or want to undergo minor renovation

to be able to be certified by MyCREST.

There are two certification pathways of rating systems for EB (existing

buildings):

1. For EB with EE FEATURES

These buildings are those that have achieved any form of green

certification or have been designed to be ‘green-based’ with

the implementation of energy saving and water saving

measures. There will be two Energy Performance Assessments.

The first Energy Performance Assessment is the gap analysis of

the current building.

After a minimum period of 6 months and only when its

occupancy has been reached more than 50%, the building must

undertake a second energy performance assessment to

measure and verify its improvement from BAU levels. The result

will be considered as result building performance in-use and

then will be compared with the business as usual for the MyCREST

point award.

39 | P a g e

Figure 2: Certification Timeline for Existing Building with “EE Features”

2. For EB – NON EE - FEATURES

Buildings that are have not achieved green credentials, or have

minimum EE standards but must undergo minor MVAC

modification or additions. There will be two Energy Performance

Assessments. The first Energy Performance Assessment is the gap

analysis of the current building.

After 6 months and when the occupancy has been reached

more than 50%, the building needs to do the second energy

performance assessment to analyse its improvement. The result

will be considered as actual building performance and then will

be compared with the business as usual for the MyCREST point

award.

Justification

A building cannot be considered ‘green’ if it is not energy efficient. The

energy used by buildings mostly generated by burning fossil fuels, which

release greenhouse gas emissions that contribute to climate change.

53 | P a g e

No building should define itself as “green” unless it consumes less

energy and generates fewer greenhouse gas emissions than average.

Approach & Strategy

Existing building energy assessment will help to identify areas of building

operations that are not operating efficiently. Implement energy-saving

operational and management practices and/or energy-efficiency

retrofits to reduce energy use to the level required to meet this

requirement.

The MyCREST rating system awards energy performance points based

on the building current energy consumption of building compared to a

Baseline Building.

According to the MyCREST rating system, the ‘Existing Building’ needs to

be clarified between Energy Efficient (EE) Building and Non-Energy

Efficient Building.

The building is considered as Energy Efficient (EE) Building if it meets the

minimum requirements from the baseline.

Building that does not comply with the requirements above will be

considered as Non-Energy Efficient Building (Non-EE).

The building is considered as Energy Efficient Building if it complies with

any of the criteria below:

1. Comply with the minimum requirement for OTTV, RTTV,

lighting and ACMV components and equipments under

item 5, 6, 7 and 8 as stated in MS 1525:2007

AND

Show a minimum of 6% energy reduction above the

design baseline of MyCREST.

54 | P a g e

2. Comply with Zone 1A requirement and Appendix G

ASHRAE 90.1 2007.

OR

3. Comply with JKR EE need statement.

OR

4. The green certified building that has achieved final

construction certification and fully commissioned.

The carbon emission factor for electricity is 0.747 kg CO2e/ unit

The Building

The actual Building Energy Consumption is the actual measured

building energy consumption. The measurement methodology can

refer to the International Performance Measurement & Verification

Protocol (IPMVP).

The IPMVP provides a “framework to determine energy and water

savings resulting from the implementation of an energy efficiency

program.” The framework provided by IPMVP has become the

industry’s standard for savings verification.

According to the IPMVP, it provides “an overview of current best

practice techniques available for verifying results of energy efficiency,

water efficiency, and renewable energy projects.” The IPMVP

addresses energy conservation measures that reduce energy through

the installation or retrofit of equipment or the modification of operating

procedures.

Large energy efficiency contracts should include at least some of the

elements recommended in the IPMVP. Often these contracts include a

55 | P a g e

savings guarantee that pays for part or all the costs of the project. The

IPMVP provides a credible guidance to help the project auditor verify

that savings have occurred and how much has realized.

There are four approaches to measuring savings that are termed as

“Options A, B, C, and D.” However, for MyCREST, only methodologies in

Option C and D will be used.

Options C (Whole Facility) and D (Caliberated Simulation)

These options are used when the nature of the ECM is not easily

measured in isolation from the rest of the building operations. This could

be typical of operational and control changes that affect many areas

of the building.

The Option C approach assesses savings at the whole-facility level by

analyzing utility bills before and after the implementation of the ECM’s.

Option D uses computer simulations and modeling of the whole facility,

usually when base year energy data is not available or reliable.

Installation of energy management control systems (EMS) and

training/awareness programs are good examples for Option C.

Generally, Options C and D involve much more time and skill to

conduct and, therefore, are going to be more costly to measure.

Existing Buildings (EB)

The underlying philosophy of this certification method is to allow

buildings that are already green or want to undergo minor renovation

to be able to be certified by MyCREST.

There are two certification pathways of rating systems for EB (existing

buildings):

3. For EB-EE FEATURES

These buildings are those that have achieved any form of green

certification or have been designed to be ‘green-based’

already implementing energy saving and water saving

measures. There will be two Energy Performance Assessments.

The first Energy Performance Assessment is the gap analysis of

the current building.

After 6 months and the occupancy has been reached more

than 50%, the building needs to do the second energy


will be considered as current building performance and then will

be compared with the baseline for the MyCREST point award.

The business as usual building will be a building energy

simulation.

ENERGY PERFORMANCE IMPACTS O&M EP26 Building Energy Audit EP 26 Cr

Building Energy Audit 1 Points

Aim

An Energy Audit is a study or survey to identify how energy is being used

in a building or plant. The primary goals of energy audit are:

1. To qualify and quantify how the building energy systems are

performing at the time of measurement,

2. How that performance can be improved, and

3. What will be the outcomes of those improvements for the Owner

in financial and non-financial terms.

Requirement

1 POINT:

Conduct a building energy audit in accordance to ASHRAE LEVEL 2

Energy Audit.

Justification

Energy Audit is a tool to identify the existing energy performance. By

conducting an energy audit, the users will have a better understanding

regarding energy balance, load pattern and wastages in their building.

The output by carried-out energy audit is an audit report with business-

as-usual and recommendations to improve the energy performance.

Approach & Strategy

This is an additional point given under MyCREST for undertaken ASHRAE

LEVEL 2 Energy Audit. As Energy audits vary in depth, depending on the

configuration of the building energy systems, the project parameters

68 | P a g e

set by the project owner. For EP 24, Improving Energy Performance, it is

sufficient to undertake ASHRAE LEVEL 1 Energy Audit to determine the

Business-As-Usual (BAU) level.

Because it usually is not possible to know where the audit process will

lead and what level of effort will be the most cost effective, ASHRAE

(American Society of Heating, Refrigerating and Air-Conditioning

Engineers) has defined three progressive levels, or types, of audits.

ASHRAE Level 1 – Walk-Through Analysis/Preliminary Audit

The Level 1 audit is alternatively called a “simple audit”, “screening

audit” or “walk-through audit” and is the basic starting point for building

energy optimization. It involves brief interviews with site operating

personnel, a review of the facility’s utility bills and other operating data,

and an abbreviated walk-through of the building. The ASHRAE Level-1

audit is geared toward the identification of the potential for energy

improvements, understanding the general building configuration, and

defining the type and nature of energy systems.

The audit should result in a preliminary, high-level, energy-use analysis

for the entire facility, and a short report detailing the findings, which

may include identifying a variety of recognizable efficiency

opportunities. Usually, this report does not provide detailed

recommendations, except for very visible projects or operational faults.

The ASHRAE Level-1 audit is intended to help the energy team

understand where the building performs relative to its peers; establish a

business as usual for measuring improvements; deciding whether further

evaluation is warranted; and if so, where and how to focus that effort.

69 | P a g e

The Level-1 also will outline the range of potential financial incentives

available from the government.

ASHRAE Level 2 – Energy Survey and Analysis

The next step for most facilities is the ASHRAE Level-2 audit/assessment.

The Level-2 project starts with the findings of the Level-1 audit, and

evaluates the building energy systems in detail to define a variety of

potential energy-efficiency improvements. This should include the

Building Envelope, Lighting, Ventilation, and Air Conditioning (MVAC),

Domestic Hot Water (DHW), Plug Loads, and Compressed Air and

Process Uses (for manufacturing, service, or processing facilities).

This study starts with a detailed analysis of energy consumption to

quantify base loads, daily and monthly variation, and effective energy

costs. From there, the study should include an evaluation of lighting, air

quality, temperature, ventilation, humidity, and other conditions that

may affect energy performance and occupant comfort. The process

also includes detailed discussions with the building ownership,

Management, and Occupants to explore potential problem areas, and

clarify financial and non-financial goals of the program.

The Level-2 audit should result in a clear and concise report and

briefing with the owner and management team describing a variety of

Energy Efficiency Measures (EEMs) including no- and low-cost

measures, modifications to system controls and building automation,

operational changes, and potential capital upgrades. The findings

should include general costs and performance metrics, as well as a

means for the owner to evaluate the EEMs and decide how to proceed

with implementation.

70 | P a g e

Many of the EEMs revealed during the ASHRAE Level-2 audit can be

implemented quickly with rapid or immediate financial payback for the

owner. Other EEMs will require more detailed analysis of benefit and

cost and the other goals that are important to the owner. The audit

should define next steps to accomplish this analysis and decision

making. Sometimes it is through discussion with manufacturers or

suppliers or other relatively simple means. For other EEMs, involving a

complex interaction among building systems and potentially large

financial investments, it may be necessary to dig deeper into the

building operation and also the human factors influencing

performance. This is where the ASHRAE Level-3 audit becomes essential.

ASHRAE Level 3 – Detailed Analysis of Capital-Intensive Modifications

Some of the system upgrades or retrofits revealed by the Level-2 audit

may require significant investments of capital, personnel, and other

limited resources. Before making this level of investment, the owner will

want to have a much more thorough and detailed understanding of

the benefits, costs, and performance expectations. This is the purpose

of the “investment-grade” Level-3 ASHRAE audit. There may be only a

few capital-intensive EEMs exposed by the Level-2 audit, or there may

be dozens for larger facilities. Investment levels can range from tens of

thousands to tens of millions of ringgit. In most cases, since this cannot

be clearly determined or accurately estimated in advance, the

recommendation and scope definition for a Level-3 audit usually is an

outcome of the Level-2 process.

The ASHRAE Level-3 audit focuses on a “whole-building computer

simulation”, where a computer program is used to model very

accurately the way the brick-and-mortar building would respond to

changes in the energy systems whether those are major MVAC retrofits

71 | P a g e

or architectural modifications to walls, windows, and roof. The ASHRAE

Level-3 audit involves much more detailed data collection over the

course of weeks or months. Data loggers typically will be placed

temporarily to monitor the operation of pumps and motors,

temperatures of affected spaces, lighting levels, switching behavior,

and other factors. These data are used to calibrate the computer

model of the facility so that the computer model responds to inputs

and changes the same way the building could be expected to

respond. This calibration is checked and validated by simulating a year

or more of past, minute-by-minute climate conditions to see if power

and energy usage in the model mirrors actual energy power and

energy usage.

Once the three-dimensional computer model is responding like the real

building, changes to energy systems can be simulated with very

accurate results. Combining that process with construction-grade cost

estimating supports informed investment decisions.

MyCREST is not only concerned with the end product but also the

facility’s lifelong, operational activities. A reward will also be given to

organisational practices. While scope 1 and 2 can be linked with (1)

design features, (2) construction processes and practices, (3)

management policies and facilities, scope 3 can be linked to the

environment for lowering carbon during lifetime operations.

As buildings in the MyCREST processes are also subject to carbon

accounting in lifecycle processes, the aim is to highlight the link of each

criterias with the different carbon emission scope in a standard carbon

accounting framework. This framework shows the different stages of the

building lifecycle, which can also include organisation/ staff policies if

these are implemented.

As such the MyCREST current initial form attempts to touch on the

aspects of scope 1, 2 and 3 but as such, it is just the beginning. Further

revision and improvements are necessary to ensure that a

comprehensive set of carbon emission implication of a building in

design and operations will eventually be developed.

Carbon Footprint

1. DEFINITION

A carbon footprint is the total greenhouse gas (GHG) emissions

caused directly and indirectly by an individual, organisation,

event or product, and expressed as a carbon dioxide equivalent

(CO2e).

75 | P a g e

A carbon footprint is measured in tonnes of carbon dioxide

equivalent (t CO2e). The carbon dioxide equivalent (CO2e)

allows the different greenhouse gases to be compared on a like-

for-like basis relative to one unit of CO2. CO2e is calculated by

multiplying the emissions of each of the six greenhouse gases by

its 100 year global warming potential (GWP).

A carbon footprint considers all six of the Kyoto Protocol

greenhouse gases: Carbon dioxide (CO2), Methane (CH4),

Nitrous oxide (N2O), Hydro fluorocarbons (HFCs), per

fluorocarbons (PFCs) and Sulphur hexafluoride (SF6).

2. CATEGORIES OF EMISSION

The calculation of GHG emissions is based on three scopes:

SCOPE 1

Direct emission resulting from activities within the organisation’s

control, which might include on-site fuel combustion,

manufacturing and process emissions, refrigerant losses and

company vehicles.

SCOPE 2

Indirect emissions from any electricity, heat or steam that the

organisation purchases and uses. Although they are not directly

in control of the emissions, they are indirectly responsible for the

release of CO2 by using the energy.

SCOPE 3

Any other indirect emissions from sources outside the

organisation direct control. Examples of Scope 3 emissions

76 | P a g e

include employee commuting and business travels, outsourced

transportations, waste disposal and water consumption.

Approach & Strategy

Existing building commissioning and energy audits will help to identify

areas of building operations that are not efficient. Implement energy-

efficient retrofits and energy-saving techniques to reduce building’s

energy use.

Choose energy-efficient office equipment, maintenance equipment,

and appliances to help reduce energy waste.

Use meters on major mechanical systems to monitor energy

consumption. In addition to efficiency improvements, consider

renewable energy options as a way to minimize the building’s

environmental impact.

Method of Calculating Emission Reduction

1. Determine boundary

The project must determine the boundary of this reporting. This is

typically all subsidiaries activities under the operation control of

the owner/operator within the activities boundary of the

initiatives

2. Select a protocol or standard for method of reporting

The project must use emission tracking protocols provided by

third party voluntary reporting program to ensure accurate and

informed estimates. Protocols for building emissions reporting can

be found in organisations such as WRI ( World Resource Institute)

Carbon trust, EPA Climate Leaders. This includes the GHG

77 | P a g e

protocol corporate accounting and standards from WRI in

electricity and transportation.

3. Select items from each SCOPE 1, 2 and 3

4. Determine the performance period or year

For example identify, report and calculate the GHG emissions

from Scope 1, 2 and 3 including building energy consumption for

the 12 month period before the performance period ends.

The start of the performance period represents the business-as-

usual GHG emission. Undertake initiatives policies and practices

to reduce GHG emissions. These can include any of the

strategies outlined in MyCREST O& M criteria or subcriteria

including building energy performance.

Report the reduction in GHG emission at the end of the

performance period and perform the comparison.

Justification

Renewable energy has a host of social, environmental, and economic

benefits. To be truly sustainable, an energy source must meet these

criteria:

1. have minimal or no negative environmental or social impact;

2. not deplete natural resources;

3. meet the needs of people today and in the future in an

accessible, equitable and efficient manner;

4. protect air, land and water;

5. have little or no net carbon or other greenhouse gas emissions;

6. be safe today and not burden future generations with

unnecessary risk.

Approach & Strategy

Suggested renewable energy use includes solar photovoltaic,

micro/mini hydro, biogas and biomass, which produce electrical

energy. The system may consist of a grid connection system whereby

the use of Feed-In-Tariff may apply.
