Summary
An Energy Audit for Your
Building is a detailed examination of how your building uses energy, aiming to
find ways to reduce consumption and save money. Under Malaysia's EECA 2024,
certain large buildings (office buildings ≥8,000 sqm GFA) may be
mandated to conduct an audit if their energy performance is low. An audit must
be performed by a Registered Energy Auditor (REA). The Ultimate Guide to
Conducting an Energy Audit for Your Building covers key steps: gathering
historical energy data, a thorough site inspection of all systems (HVAC,
lighting, etc.), detailed analysis of findings, generation of a comprehensive
report with recommended improvements, and crucially, the implementation and
ongoing monitoring of those recommendations. The Energy Audit Conditional Grant
(EACG 2.0) from SEDA Malaysia can help cover audit costs.
1. Why Your Building
Needs an Energy Audit: More Than Just Saving Money
If you own or manage a
building in Malaysia, whether it's an office, a factory, a hotel, or even a
large apartment complex, you know that energy bills are a huge expense. Every
month, a big chunk of your budget goes towards electricity, air conditioning,
and other energy uses. What many people don't realize is that a lot of that
energy is often wasted without anyone knowing.
This is where an Energy
Audit for Your Building comes in. Think of it like a medical check-up for
your building's energy use. Just as a doctor checks your health to find
problems, an energy audit checks your building to find where it's wasting
energy. Once you know where the waste is, you can fix it and save money.
But saving money isn't the
only reason. Malaysia has a new law called the Energy Efficiency and
Conservation Act (EECA) 2024, which became effective on January 1, 2025.
This law makes energy efficiency a serious matter, and for some large
buildings, it means getting an energy audit might even be mandatory if
your building isn't performing well enough.
So, whether you're driven by
wanting to save money, improve comfort for people in your building, boost its
value, or simply follow the new laws, understanding The Ultimate Guide to
Conducting an Energy Audit for Your Building is a super important step.
2. Is Your Building
Covered by the New Law? (EECA 2024)
The EECA 2024 doesn't ask every
building in Malaysia to get an energy audit. It focuses on larger buildings
that use a lot of energy. The law specifies who needs to follow certain rules,
and this includes "Persons in Charge of Buildings." This basically
means the owner, manager, or anyone who has control over a building's
operations.
Your building might be
directly affected if:
- It is primarily an office building.
The current rules under EECA 2024 are focused on this type of commercial
building.
- It has a Gross Floor Area (GFA) of
8,000 square meters (m2) or more.
- What's GFA?
It's the total indoor floor space of your building, including all levels.
The rules have specific ways to measure this exactly.
- This size limit targets bigger office
buildings where there's usually a greater chance to save a lot of energy.
So, what happens if your
building fits these rules?
Under EECA 2024, these
buildings must first get a Building Energy Intensity (BEI) label from
the Energy Commission (EC). This label is like a report card that shows how
energy-efficient your building is. It might have a star rating, like 1 to 5
stars, with more stars meaning better energy performance.
When does an energy audit become a must-do?
An energy audit becomes legally
required for your building if:
- Your building's BEI label shows that
its energy performance is below a certain minimum standard set by the
EC (for example, if it scores below a 2-star rating).
- If this happens, the Energy Commission
will send you an official notice saying that your building is not
meeting the energy performance standards.
- Once you receive this notice, you will
then be required by law to conduct a full energy audit performed by
a qualified professional.
Even if your building doesn't
fit these exact rules for a mandatory audit right now, doing an energy audit is
still a very smart move. It's one of the best ways to find hidden savings and
make your building better. The Ultimate Guide to Conducting an Energy Audit
for Your Building will show you how to do it effectively, whether it's
required or done by choice.
3. Big Benefits: Why
an Energy Audit is a Smart Investment
Even if the law doesn't force
you to do an energy audit, choosing to do one can bring many great benefits to
your building and your business. It's often one of the best investments you can
make!
Here's why taking steps in The
Ultimate Guide to Conducting an Energy Audit for Your Building is a really
good idea:
- Huge Money Savings on Energy Bills:
- This is the most obvious and often the
most exciting benefit. An energy audit helps you find all the places
where your building is wasting energy. This could be old, inefficient air
conditioners, lights left on all the time, leaky windows, or even outdated
machinery.
- Once you know where the waste is, you can
fix it. By making smart changes recommended by the audit, many buildings
see their energy bills drop by 10%, 20%, or even 30% or more.
Imagine how much money that adds up to each year that you can put back
into your business or building improvements!
- More Comfortable Building for Everyone:
- A building that uses energy well is
usually a more comfortable place to be. For example, if your air
conditioning system is old, some rooms might be freezing while others are
too hot. An audit can fix these "hot and cold spots."
- Better temperature control, fresh air,
and good lighting make tenants, employees, or residents happier and more
productive. When people are comfortable, they're more likely to stay in
your building or work better.
- Increases Your Building's Value:
- Think about it: if someone wants to buy
or rent a building, would they choose one with super high energy bills or
one with low, predictable bills? The answer is obvious!
- Energy-efficient buildings are worth more
in the market. They're seen as modern, cheaper to run, and better for the
environment. Having a good energy performance rating (like a high BEI
label from EECA) can be a major selling point.
- Better for the Environment (and Your
Reputation):
- When your building uses less energy, it
means power plants burn less fuel, which means less pollution (like CO2)
goes into the air. This helps fight climate change and makes your company
more environmentally friendly.
- Being known as a "green" or
sustainable business can boost your company's image, attract
environmentally conscious customers, and even help you hire good
employees who care about these things.
- Helps You Follow New Laws (Like EECA
2024):
- As we discussed, for certain large
buildings, an energy audit might become mandatory if your energy
performance isn't good enough.
- By doing an audit (even before it's
mandatory) and fixing the problems it finds, you make sure your building
is ready to meet any legal requirements. This helps you avoid fines from
the Energy Commission, which can be as much as RM50,000.
- Opens Doors to Government Grants and Help:
- The Malaysian government wants buildings
to be more energy-efficient. There are programs like the Energy Audit
Conditional Grant (EACG 2.0) from SEDA Malaysia that can help pay for
some of the cost of a professional energy audit.
- Also, some energy-saving projects found
by the audit might qualify for tax benefits, like the Green Investment
Tax Allowance (GITA). An audit helps you find these opportunities and get
financial support.
Considering all these
benefits, it's clear that going through The Ultimate Guide to Conducting an
Energy Audit for Your Building is not just about a one-time check; it's a
strategic move that helps your building and business thrive for years to come.
4. The Ultimate Guide
to Conducting an Energy Audit for Your Building: The Step-by-Step Checklist
Ready to get started? Here's
your clear, step-by-step checklist for how a proper energy audit for your
commercial building is done. This detailed guide will help you understand The
Ultimate Guide to Conducting an Energy Audit for Your Building.
Very Important: For
any official energy audit (especially if it's mandatory for EECA 2024
compliance), it must be done by a Registered Energy Auditor (REA). An
REA is a professional who is officially registered with the Energy Commission
and has the special skills and knowledge to perform these detailed audits.
While you can do simple checks yourself, the real, official audit needs an REA.
Here's the checklist:
- Step 1: Planning and Getting Ready (Before
the Auditor Visits)
- Know Your Goals:
Before anything else, decide what you want from the audit. Is it just to
follow the law? Do you want to cut your energy bills in half? Do you want
to make your building super comfortable? Telling the auditor your goals
helps them focus their work.
- Gather Building Documents and Data:
This is a crucial step for you to do before the auditor arrives.
- Energy Bills:
Collect at least the last 12 to 24 months of all your energy bills
(electricity, natural gas, diesel, water, etc.). These bills show your
history of energy use.
- Building Blueprints/Drawings:
Find any drawings of your building's layout, electrical systems, air
conditioning (HVAC) systems, and plumbing.
- Equipment Details:
Make a list of all your big energy-using machines and systems. This
includes your air conditioners (chillers, AHUs), boilers, water heaters,
types of lights, and large motors. Write down their age and any
maintenance records.
- Operating Schedules:
How many hours a day, days a week, and weeks a year does your building
operate? When are most people in the building? Are there different
schedules for different parts of the building?
- Previous Maintenance/Upgrade
Records: Have you ever fixed or upgraded any
energy-related equipment? Keep records of that.
- Pick a Contact Person:
Choose one person from your staff (like a facilities manager or
operations manager, or your Registered Energy Manager if you already have
one) to be the main contact for the auditor. This person will help the
auditor get into different areas, answer questions, and provide needed
documents.
- Look into Grants (Like EACG 2.0):
Check if you can apply for the Energy Audit Conditional Grant (EACG
2.0) from SEDA Malaysia. This grant can help pay for some of the
audit costs if you use an EC-registered Energy Service Company (ESCO) to
do the audit. Apply for this early!
- Choose a Registered Energy Auditor (REA):
This is very important. Make sure the auditor you pick is officially
registered with the Energy Commission (EC). Ask for their past
experience, what special training they have, and talk to other clients
they've worked with. Get a clear proposal that explains what they will do
and how much it will cost.
- Step 2: On-Site Inspection and Data
Gathering (The Auditor's Visit)
- First Meeting:
The REA will usually start with a meeting with your contact person to
discuss the building, your goals, and how they plan to do the audit.
- Walking Tour of the Building:
The REA will walk through every part of your building, from the basement
to the roof. They will look closely at all the systems that use energy:
- Air Conditioning (HVAC):
They'll check your chillers, cooling towers, pumps, air handling units,
and ventilation fans. They'll look at how old they are, how well they're
working, and if the controls are set correctly.
- Lighting:
They'll look at all your lights (LED, fluorescent, etc.), how many there
are, if they have sensors that turn them off when no one is around, and
if they're too bright or not bright enough.
- Building Shell (Walls, Roof,
Windows): They'll check the outside of your
building for things like cracked windows, poor insulation in the roof or
walls, or gaps where air can leak out. These are like holes in a bucket
for energy!
- Electrical Systems:
They'll look at your electrical panels, motors, and how power is
distributed throughout the building.
- Water Heating:
If you have boilers or large water heaters, they'll check their
efficiency and how hot the water is being kept.
- Other Equipment:
This includes computers, office machines, kitchen appliances, and any
other equipment that uses energy.
- Taking Measurements and Using Tools:
The REA might use special tools to measure things like:
- Temperature and humidity in different
areas.
- The amount of light in rooms.
- How much electricity specific machines
are using.
- They might even put temporary "data
loggers" on your electrical systems to record energy use over a few
days or weeks to get a very accurate picture.
- Talking to Staff:
The REA will often talk to your building's maintenance team, facilities
staff, and even some tenants or employees. They'll ask about any
problems, uncomfortable areas, or ideas for saving energy that people
have noticed.
- Step 3: Analyzing the Data and Finding
Energy Saving Ideas
- Compare Your Building:
The REA will take your building's energy use and compare it to other
similar buildings (this is called "benchmarking"). This helps
you see if your building is using more or less energy than average.
- Do the Math:
Using all the information they collected, the REA will do detailed
calculations. They'll figure out:
- Exactly how much energy each part of
your building uses (e.g., how much for air conditioning, how much for
lights).
- Where the biggest wastes are happening.
- How much energy and money you could save
if you made certain changes.
- How long it would take for the money
saved to pay back the cost of an improvement (this is called
"payback period").
- List of Energy Saving Ideas (ECMs):
This is the main outcome of the audit. The REA will give you a list of
specific recommendations, often called Energy Conservation Measures
(ECMs). These ideas could be:
- Switching all your old lights to new,
efficient LED lights.
- Adjusting the temperature settings for
air conditioning to save energy.
- Installing smart controls that turn off
lights or AC when nobody is around.
- Adding more insulation to your roof or
walls.
- Fixing air leaks around windows and
doors.
- Upgrading to newer, more efficient air
conditioners or motors.
- Suggesting simple habits like reminding
people to turn off lights when they leave.
- Even looking into putting solar panels
on your roof.
- Step 4: Getting the Audit Report
- After all the work, the REA will give you
a full Energy Audit Report. This is the official document that
summarizes everything they found and recommend.
- What's in the Report:
- A short summary (Executive Summary) with
the main findings and best ideas.
- Information about your building and how
it's used.
- Details on your past energy use and how
it compares to others.
- A detailed list of all the energy-saving
ideas (ECMs). For each idea, it will tell you:
- What the idea is.
- How much energy it could save (in kWh,
GJ, etc.).
- How much money it could save you each
year (in RM).
- How much it would cost to do the
improvement (in RM).
- How long it would take for the savings
to pay back the cost (payback period in years).
- How much CO2 pollution it would reduce.
- A list of the best recommendations,
usually ordered by how quickly they pay for themselves.
- Information on how the audit was done.
- Step 5: Taking Action and Checking Results
- Review the Report Carefully:
Your team should sit down with the REA to go through the report. Your
Registered Energy Manager (if you have one) should be deeply involved
here.
- Make an Action Plan:
Based on the report, decide which energy-saving ideas you will put into
action. It's smart to start with the ones that save a lot of money
quickly or cost very little.
- Get Funding:
Figure out how you will pay for the improvements. Remember to look into
any grants you applied for!
- Do the Work:
Go ahead and make the changes recommended in the report.
- Keep Monitoring:
This step is super important! After you make the improvements, you need
to keep tracking your energy bills and use. This shows you if the changes
are actually saving the money and energy that the audit predicted. It
proves the value of the audit and your efforts.
- Send to EC (if mandatory):
If your audit was required because your building's BEI was too low,
you'll need to submit the audit report and your plan for improvements to
the Energy Commission.
By following The Ultimate
Guide to Conducting an Energy Audit for Your Building carefully, you're not
just following rules; you're actively turning your building into a more
efficient, cost-effective, and environmentally friendly asset.
