The temperature during the summers in the Philippines is increasing annually. The World Meteorological Organisation reported that 2024 was the hottest year in recorded history, while PAGASA has verified that 2024 was one of the hottest years in the Philippines since records were first collected. The demand for electricity, particularly for air conditioning, increases with temperature rises, and thus, commercial buildings throughout the Philippines have experienced considerable increases in their operational expenses.
There may be as much as 20-30% wasted energy from air conditioning (AC) use in most companies due to inefficient buildings, improper usage, and insufficient routine maintenance of HVAC equipment.
However, businesses can achieve up to 20-35% cost savings on AC cooling expenses by employing the following practical and technology-based methods to create a more efficient cooling operation without compromising comfort or employee productivity.
Common Energy-Wasting Behaviors in Commercial Buildings
Many workplaces unknowingly waste energy through simple, avoidable habits. Here are the most common issues:
1. Overcooling Spaces
Every degree below 24°C increases energy consumption by 3–5%. Many offices set thermostats too low, resulting in unnecessary energy waste.
2. Doors and Windows Left Open
An open door or window cancels out cooling efforts; your system ends up cooling the outdoors.
3. Running AC in Empty Spaces
Many facilities run AC in unoccupied offices or during off-hours, burning thousands of pesos monthly.
4. Dirty Filters and Blocked Vents
Dirty filters force the system to work harder, increasing consumption and reducing airflow. Poor ducting and airflow can reduce efficiency by up to 30%.
5. Poor Occupancy Scheduling
Running the cooling system at maximum output even in times of low occupancy results in wasted energy. Changing this behavior will be the first and easiest way to decrease your cooling costs.
Practical Energy-Saving Tips for Offices and Factories
In order to reduce cooling expenses, it is not enough to simply upgrade equipment. You also need to develop good daily habits and operational practices. Companies operating in the Philippines can significantly reduce their energy usage through several very simple and practical steps. The following are some straightforward and actionable suggestions that can be implemented at a facility level for both immediate and long-term savings.
1. Optimize Thermostat Settings
- Maintain 24–25°C for ideal comfort and savings.
- Use programmable thermostats to automatically adjust temperature during off-hours, weekends, and holidays.
2. Follow Regular HVAC Maintenance
To maintain cooling efficiency:
- Schedule quarterly HVAC maintenance.
- Replace filters monthly.
- Seal leaks around doors and windows.
- Ensure vents and ducts are unobstructed.
3. Improve Building Ventilation and Zoning
- Cool only occupied zones.
- Close vents in unused areas.
- Use ceiling fans to help circulate air.
- Use blinds or window films to reduce heat gain by 15–20%.
4. Manage Equipment Usage
Schedule heat-generating equipment (e.g., ovens, heavy machinery) during early morning or late afternoon to reduce cooling load during peak heat.
5. Train Employees on Cooling Efficiency
Simple habits like closing doors and avoiding unnecessary thermostat adjustments lead to consistent savings.
Technology Solutions: Smart AC, Inverter Systems & Energy Management
Modern technology can dramatically reduce cooling costs and improve energy efficiency.
1. Smart Thermostats
Smart thermostats adjust cooling based on occupancy and usage patterns. Businesses save 10–15% just by installing them.
2. Inverter Aircon Systems
Inverter compressors adjust speed based on cooling demand, reducing energy consumption by 30–40% versus traditional systems.
3. Energy Management Systems (EMS)
EMS platforms provide real-time monitoring and control of energy use. They optimize cooling loads, detect inefficiencies, and reduce operating expenses.
4. Smart Energy Audits
Energy audits identify where cooling energy is wasted and which improvements will deliver the fastest ROI.
Conclusion
In the Philippines, hot summers mean smart cooling requires smart strategies. Just by using simple behavior changes, you can save thousands/month. To maintain the air conditioning system or unit to run at its efficient capacity. Technology provides automation and optimization. Together, these three strategies will cut your air conditioning costs down immediately by 20-35%.
You don’t have to choose between comfort and savings; SMART energy efficiency practices will provide both. Your business becomes more profitable, your team stays comfortable, and your impact on the environment is less.
