1. Why Energy Saving is Super Important for Buildings in Malaysia

If you own or manage a building in Malaysia, you know how much money goes into electricity bills. Buildings, especially commercial ones like offices, shopping malls, hotels, and factories, use a huge amount of energy. In Malaysia, buildings can account for a big chunk of the country's total electricity demand.

What's making energy saving even more important right now?

• Rising Electricity Costs: Tenaga Nasional Berhad (TNB), our main electricity provider, often adjusts its tariffs. With the new tariff structure effective July 2025, electricity bills for businesses are becoming more detailed and potentially more expensive, especially if you have high "Maximum Demand" or use a lot of power during "peak hours." Saving energy directly cuts these costs.
• New Laws (EECA 2024): The Malaysian government introduced the Energy Efficiency and Conservation Act (EECA) 2024, which became law on January 1, 2025. This Act makes it mandatory for certain "Energy Consumers" (buildings or facilities using more than 21,600 Gigajoules (GJ) of energy per year, which is roughly 6 million kWh/year) to:
• Appoint a Registered Energy Manager (REM).
• Develop and implement an Energy Management System (EnMS).
• Submit Energy Efficiency & Conservation (EE&C) reports.
• Get regular energy audits.
• For specific buildings (like large office buildings), the law also requires getting an Energy Intensity Label and meeting certain performance standards. If your building doesn't meet these standards, you might need to do an energy audit and create an improvement plan.
• Being "Green" (Sustainability/ESG): More and more, customers, investors, and even your own employees want to see that your business cares about the environment. Reducing your building's energy use means less pollution (fewer greenhouse gases), which helps Malaysia achieve its goal of being carbon neutral by 2050. This is part of what's called ESG (Environmental, Social, and Governance), which is becoming very important for businesses.
• Operational Efficiency: Saving energy isn't just about cutting bills; it often means your building is running more efficiently. This can lead to better comfort for occupants, fewer equipment breakdowns, and a more productive environment.

So, saving energy is not just a nice-to-have; it's becoming a must-do for many buildings in Malaysia. Let's look at The Top 5 Energy Saving Opportunities Found in Most Buildings.

 

2. The Top 5 Energy Saving Opportunities Found in Most Buildings

For most buildings in Malaysia, especially those in our hot and humid climate, electricity is the main energy source, and some areas typically use a lot more electricity than others. Knowing where the most energy is used helps you focus your efforts for the biggest savings.

Here are the top 5 areas where you can find significant energy-saving opportunities:

Opportunity 1: Air Conditioning and Ventilation Systems (ACMV)

This is by far the biggest energy guzzler in most Malaysian buildings. Studies show that air conditioning and mechanical ventilation (ACMV) systems can account for 50% to over 60% of a building's total electricity consumption!

• Why it wastes energy:
• Old or inefficient units: Older AC units use much more power to cool the same space.
• Poor insulation: If your walls and windows aren't well insulated, hot air leaks in, making your AC work harder.
• Incorrect temperature settings: Setting the thermostat too low (e.g., below 24°C) uses a lot more energy.
• Lack of maintenance: Dirty filters, low refrigerant levels, or faulty parts make the system less efficient.
• Running when not needed: Cooling empty rooms or after office hours.
• Over-cooling: Cooling spaces more than necessary.
• How to save energy:
• Optimize Temperature Settings:
• Raise the thermostat to a comfortable yet energy-efficient temperature, typically 24°C to 26°C. Even raising it by 1°C can save a surprising amount of energy.
• Encourage occupants to dress appropriately for the climate.
• Regular Maintenance:
• Clean or replace air filters monthly. Dirty filters restrict airflow and make the unit work harder.
• Schedule professional servicing at least twice a year to check refrigerant levels, clean coils, and inspect ducts.
• Use Programmable Thermostats or Smart Controls:
• Set schedules so the AC automatically adjusts temperatures or turns off during non-operating hours (evenings, weekends, holidays).
• Occupancy sensors can turn off AC in empty rooms.
• Improve Ventilation:
• Ensure proper fresh air ventilation without over-ventilating, which brings in more hot, humid air for the AC to cool. Use heat recovery ventilators where appropriate.
• Consider Upgrades:
• If your AC units are very old, consider replacing them with high-efficiency models (e.g., with high COP/EER ratings or Inverter technology). While an investment, the savings can be substantial.
• Look into centralized chilling systems if you have a large building, as these can be very efficient when well-managed.

 

Opportunity 2: Lighting Systems

Lighting is another major energy user in buildings, often accounting for 20-25% of total electricity consumption.

• Why it wastes energy:
• Old technology: Using outdated incandescent bulbs or inefficient fluorescent tubes.
• Over-lighting: Illuminating areas more brightly than needed.
• Lights left on: Leaving lights on in unoccupied rooms, after hours, or when natural light is sufficient.
• How to save energy:
• Switch to LED Lighting:
• This is one of the quickest and most impactful upgrades. LEDs (Light Emitting Diodes) use significantly less energy (up to 75-80% less than incandescent bulbs) and last much longer.
• Replace all fluorescent tubes, downlights, and traditional bulbs with LED equivalents.
• Install Occupancy Sensors:
• These sensors automatically turn lights off when a room is empty and on when someone enters. Ideal for restrooms, storage rooms, meeting rooms, and hallways.
• Utilize Daylight Harvesting Controls:
• Use sensors that dim or turn off artificial lights when enough natural daylight is available near windows.
• Task Lighting:
• Instead of brightly lighting an entire large area, use more focused task lighting (e.g., desk lamps) in specific work areas and reduce general ambient lighting.
• Optimize Lighting Levels:
• Conduct a lighting audit to ensure areas are not over-lit. You might be able to reduce the number of light fixtures or use lower wattage bulbs in some areas while still meeting safety and comfort standards.
• Regular Cleaning: Keep light fixtures clean to maximize light output and avoid needing higher wattage bulbs.

 

Opportunity 3: Building Envelope (Walls, Windows, Roof)

The "building envelope" refers to everything that separates the inside of your building from the outside environment – your walls, roof, windows, and doors. A leaky or poorly insulated envelope means your AC has to work harder to fight off heat gain from outside.

• Why it wastes energy:
• Poor Insulation: Walls and roofs without proper insulation allow heat from the sun to easily transfer into the building.
• Inefficient Windows: Single-pane windows or clear glass windows let a lot of heat in.
• Air Leaks: Gaps around windows, doors, pipes, or electrical outlets allow conditioned air to escape and hot, humid air to enter.
• How to save energy:
• Improve Insulation:
• Add or improve insulation in your roof space. This is often one of the most cost-effective ways to reduce heat gain from the sun.
• Consider adding insulation to external walls if it's feasible for your building type.
• Window Treatments:
• Install solar window films or low-emissivity (low-e) glass to block heat while still allowing light in.
• Use external shading devices like awnings, fins, or vertical louvers to block direct sunlight.
• Ensure windows and doors are well-sealed with weatherstripping and caulking to prevent air leaks.
• Cool Roofs:
• Use light-colored or reflective materials on your roof that reflect sunlight instead of absorbing it, which keeps the building cooler.
• Vegetation/Landscaping:
• Strategic planting of trees and shrubs around the building can provide natural shading, reducing solar heat gain.

 

Opportunity 4: Office Equipment and Appliances

While individual pieces of office equipment (computers, printers, refrigerators, water dispensers) might not seem like big energy users, their combined effect, especially if left on 24/7, can be substantial (often around 10-15% of total building energy).

• Why it wastes energy:
• Always On: Equipment left running overnight, on weekends, or when not in use.
• Old Models: Older equipment is generally less energy-efficient.
• Phantom Load/Vampire Drain: Devices still drawing power even when turned off (but still plugged in).
• How to save energy:
• "Turn It Off" Policy:
• Encourage employees to power down computers, monitors, and other equipment at the end of the workday and before long breaks.
• Implement automatic shutdown features on computers.
• Use Power Strips:
• Plug multiple devices into power strips and switch off the strip at the end of the day to eliminate phantom load.
• Purchase Energy-Efficient Models:
• When buying new equipment (computers, printers, refrigerators, water coolers), look for Energy Star certified products or those with high energy efficiency ratings. In Malaysia, look for products with 5-star energy labels from the Energy Commission.
• Optimize Printer Usage:
• Consolidate printing to fewer, more efficient multi-function devices. Use duplex printing as default.
• Server Room Optimization:
• For buildings with server rooms, ensure efficient cooling, proper server rack management, and consider virtualization to reduce the number of physical servers.

 

Opportunity 5: Energy Management Systems (EnMS) and Monitoring

This is less about specific equipment and more about a systematic approach to understanding and controlling your building's energy use.

• Why it wastes energy:
• Lack of Visibility: Not knowing exactly how and where energy is being used.
• Manual Control: Relying on people to remember to turn things off or adjust settings, which is prone to human error.
• No Goals: Without targets or a system to track progress, it's hard to improve.
• How to save energy:
• Conduct an Energy Audit: This is the most important first step for any building. A professional energy audit (especially by a Registered Energy Auditor (REA), which may be required under EECA 2024 for large buildings) will identify exactly where and how your building is wasting energy, and suggest specific solutions with estimated savings and payback periods.
• Install Sub-meters:
• Put meters on different parts of your building (e.g., lighting circuits, AC systems, production lines) to see exactly how much energy each area uses. This helps identify "hotspots."
• Implement a Building Management System (BMS) or Energy Management System (EMS):
• These smart systems allow you to centrally monitor, control, and optimize various building systems (AC, lighting, ventilation, pumps) automatically based on schedules, occupancy, and external conditions.
• They can identify faults, optimize start/stop times, and reduce human error.
• Establish an Energy Management Team/Policy:
• For larger buildings, create a team (or utilize your Registered Energy Manager if required by EECA) to oversee energy initiatives, set goals, track progress, and involve employees. Develop a clear energy policy.
• Employee Engagement:
• Educate and encourage all occupants to be energy-conscious. Simple actions like turning off lights when leaving a room or unplugging chargers can add up. Post reminders and celebrate energy-saving successes.
