As summer arrives, running the air conditioning all day can consume a large amount of electricity. Here are energy-saving tips provided by the Ministry of Economic Affairs’ Energy Bureau: 1. Choose air conditioners with a high CSPF; every increase of 0.1 can save 2-3% of electricity. 2. Set the air conditioning temperature to 26-28℃, and use automatic temperature control to avoid overcooling. 3. Clean the air filters every two weeks. 4. Use a fan in conjunction with the air conditioning to enhance cooling efficiency. 5. Turn off the compressor 30 minutes before leaving work and switch to fan mode. 6. Install curtains to reduce solar radiation heat. 7. Ensure that the air-conditioned area is isolated from the outside to prevent cool air leakage. 8. Avoid using centralized air conditioning during large events whenever possible. 9. Install a variable frequency control system to save electricity. In terms of lighting, use energy-efficient LED fixtures, increase the reflectivity of ceiling colors, and install sensor switches to reduce unnecessary electricity usage. Elevators can also be set to stop on specific floors and to automatically turn off lights, encouraging more people to take the stairs or walk for added exercise. By implementing these measures, you can not only reduce electricity bills but also contribute to environmental protection.

Summer is approaching, and the sun outside is glaring, making it hard to resist turning on the air conditioning to enjoy the cool air indoors. If you need to keep the air conditioning on all day, are there some ways to save electricity? Here are some energy-saving tips that can help everyone save both electricity and money during the scorching summer.

• Choose an air conditioner with a high CSPF value; the higher the CSPF, the more energy-efficient the air conditioner is. Generally, for every increase of 0.1 in the CSPF value, you can save 2-3% on air conditioning electricity costs.

• It is recommended to set the air conditioning temperature between 26-28℃ and install automatic temperature control devices to avoid energy waste caused by excessive cooling.

• The indoor temperature should not be lower than 5℃ from the outdoor temperature, as this can negatively impact health.

• Clean the air filter every two weeks; a dirty filter can lead to electricity waste.

• Using air conditioning in conjunction with a fan can distribute air more evenly, allowing you to moderately raise the air conditioning temperature to save electricity.

• Turn off the compressor (switch from cooling to fan mode) 30 minutes before leaving work to reduce power consumption.

• Install blinds or curtains on east-west facing windows to reduce sunlight radiation heat entering the room and decrease the air conditioning load.

• The air conditioning area should be isolated from the outside; ensure doors and windows are tightly closed to prevent cool air from leaking out or hot air from coming in.

• Avoid using central air conditioning during long weekends or times with fewer people to prevent low operating efficiency.

• For air conditioning systems, install variable frequency controls to reduce power consumption.

Lighting energy-saving tips:

• Set up lighting according to illumination standards, and choose LED lamps (or bulbs) or fixtures with appropriate lumen levels to significantly improve energy efficiency.

• Ceilings and walls should use light colors with high reflectance to enhance light diffusion and reduce the number of fixtures needed.

• Temporarily turn off some lights in corridors and passageways where low illumination is required.

• Encourage zoned responsibility management; the habit of turning off lights can effectively reduce electricity consumption.

• Install daylight sensors that automatically lower the brightness or turn off lights during the day when there is ample natural light.

• Install motion sensors in places like conference rooms and restrooms to automatically turn lights on and off, which is convenient and saves energy.

• Regularly clean light fixtures to avoid contaminants that can affect lighting efficiency.

• Design lighting circuits for area control, activating as needed to achieve energy-saving effects.

• Check the illumination levels in various environments to avoid excessive lighting.

Elevator energy-saving suggestions:

• If there are two elevators, you can set them to stop at different floors to save power.

• The elevator should automatically stop after remaining idle for more than three minutes.

• When traveling three floors or fewer, try to walk instead of taking the elevator.

• Choose elevators with regenerative drive systems to improve energy efficiency.

• The cooling ventilation in the elevator machine room should have temperature control switches to manage operation.

Energy-saving tips for electrical appliance usage:

• Select appliances with an energy efficiency rating of 1 or 2, and cut off the power to appliances that are not in use for long periods.

• Choose office equipment with energy-saving features that automatically enter sleep mode to reduce power consumption.

• Regularly review electricity contracts and capacity settings to optimize peak usage.

• Select high-efficiency motors to improve operational efficiency.

Practicing energy-saving actions not only saves money but also contributes to environmental protection!
