As summer approaches, many people choose to enjoy air conditioning indoors, but this also means that electricity expenses will increase. To save on electricity, the Bureau of Energy, Ministry of Economic Affairs, provides some effective energy-saving suggestions: choose air conditioners with a high CSPF value, set the air conditioning temperature between 26-28°C, and regularly clean the filters. Additionally, use fans to promote air circulation, turn off unnecessary air conditioning equipment, and install shading devices on windows to lower indoor temperatures. Regarding lighting, opt for energy-efficient LED fixtures, use motion sensors, and clean fixtures regularly to improve efficiency. For elevators, it is recommended to reduce the number of operating elevators and choose to walk for distances within three floors. Following these methods can effectively reduce electricity bills while also contributing to environmental protection.

Summer has arrived again, and the sunlight outside is glaring, making people want to turn on the air conditioning and retreat indoors to enjoy the coolness. If the air conditioning needs to be running all day, are there any energy-saving methods? Here are some energy-saving tips to help everyone enjoy the air conditioning while saving electricity and expenses.

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

• It is recommended to set the air conditioning temperature between 26-28℃ and install automatic temperature control devices to avoid wasting energy due to excessively low temperatures. For rooms that are frequently entered and exited, the indoor temperature should not be lower than 5℃ above the outdoor temperature, to maintain health.

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

• Using a fan in conjunction with the air conditioning can help distribute cool air evenly and maintain comfort while slightly raising the temperature to save electricity.

• Thirty minutes before leaving work, consider turning off the compressor and switching to a fan mode to reduce the air conditioner's power consumption.

• Installing blinds or curtains on windows can reduce solar radiation heat entering indoors, thus lowering the air conditioner's load and electricity consumption.

• Ensure that the air-conditioned area is isolated from the outside environment and that doors and windows are tightly closed to prevent cool air leakage and hot air influx, which increases the air conditioner's load.

• Avoid using the central air conditioning during long holidays or when the number of people is low, as operating the equipment under low load conditions can lead to high costs.

• Consider adding variable frequency control to the air conditioning system to achieve better energy-saving effects.

Regarding lighting energy-saving tips:

• Set lighting according to illumination standards; it is advisable to choose LED fixtures with appropriate lumen counts, where the higher the efficiency, the lower the wattage.

• It is recommended to use light colors with high reflectivity for ceilings and walls to enhance the diffuse effect of light and reduce the number of fixtures needed.

• In places with low illumination demands like corridors and passages, configure light grouping controls or reduce the number of light tubes; in high illumination demand areas, automatic sensing devices can be used to increase brightness.

• Implement zoned responsibility management to turn off unnecessary lighting and cultivate the habit of turning off lights when not in use.

• Install daylight sensors to automatically lower the brightness of window edge fixtures or even turn off the lights during the day when there is sufficient natural light.

• Install sensor switches in places like meeting rooms and restrooms to automatically control the lights, which is both convenient and energy-saving.

• Regularly clean fixtures and light tubes to avoid dirt affecting illumination efficiency.

• Design fixtures for regional control with independent switches to turn on lighting based on actual needs, achieving effective energy saving.

• Review whether the illumination levels in each environment are reasonable and if the number of lights used is appropriate; moderate lighting can avoid harsh glare.

Small tips for elevator energy savings:

• If there are two elevators, set one to stop on odd floors and the other on even floors to save electricity.

• The lighting and ventilation system in the elevator should automatically stop operating after three minutes of standby.

• Walk whenever possible for floors three and below instead of taking the elevator.

• When installing or replacing an elevator, choose a variable frequency elevator equipped with regenerative braking devices for improved efficiency.

• The cooling and ventilation system in the elevator machine room should be controlled by a temperature control switch to save electricity.

Smart strategies for saving electricity for appliances:

• Choose home appliances with energy efficiency ratings of 1 or 2 and other electrical products that meet energy efficiency standards to effectively save electricity.

• Unplug appliances that are not in use for extended periods to reduce standby power waste.

• Purchase office equipment that features power-saving functions, allowing it to automatically enter sleep mode when not in use.

• Ensure that the power voltage is maintained within ±5% stability to avoid waste.

• Regularly check and adjust power capacity and assess the feasibility of reducing peak power consumption.

Saving energy starts from the little things; not only can it save expenses, but it also helps protect the environment. Let’s work together to contribute to our planet!
