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

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.

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.

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.

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.

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.

Emissions Reduction Reporting 3 Points
Aim
To identify sources of Greenhouse Gas (GHG) emissions within a facility,
company or an organisation and report any reductions in conventional
energy and GHG emissions based on strategies, policies or initiatives
implemented during the performance year.
Requirement
3 POINTS:
To report, track and record emission reductions based on SCOPE 1,
SCOPE 2 AND SCOPE 3 including all energy and emission reduction
initiatives including a renewable initiatives or carbon trading initiatives.
Justification
Report on emission reduction helps an organization to document their
building carbon emission. The organization can compare and improve
their policy related to building performance and transportation as part
of their efforts to reduce carbon emission.
MyCREST criteria and sub-criteria outlined in MyCREST updated
scorecards in terms of carbon emission categories as outlined by
Carbon Trust Guide i.e. scope 1, scope 2 and 3, which represent an
internationally recognised definition and framework of carbon emission
audit or assessment for an organisation or product. This is also linked to
the lifecycle concept of MyCREST in order to be more holistic in terms of
assessing the carbon impact of buildings.
74 | P a g e
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.
