As summer arrives, using air conditioning becomes a daily routine, but how can we save electricity and money? The Ministry of Economic Affairs' Energy Bureau offers several energy-saving tips: choose air conditioners with high CSPF ratings and set the temperature appropriately, clean the filters regularly, use fans to evenly distribute the cool air, turn off the compressor before leaving work, and install curtains to reduce heat entry. Additionally, for lighting, it is recommended to use LED lighting, set up automatic sensors, cultivate the habit of turning off lights when leaving a room, and regularly clean the fixtures. For elevators, setting up floor stops, walking when possible, and choosing variable frequency elevators can effectively save energy. Selecting energy-efficient appliances and cutting off power to devices that are not in use for long periods is also a good choice. These methods not only help reduce energy consumption but also contribute to environmental protection.

Summer has arrived again, and the glaring sunlight outside makes it hard to resist turning on the air conditioning and hiding indoors to enjoy. If the air conditioning must run all day, are there any ways to save electricity? Below are some tips compiled to help everyone enjoy the cool while saving money.

• Choose air conditioners with a high CSPF; the higher the CSPF value, the more energy-efficient it is. For every 0.1 increase, you can save about 2-3% in electricity usage.
• Set the air conditioning temperature between 26-28℃ and install automatic temperature control devices to avoid unnecessary energy waste.
• For rooms that are frequently accessed, the indoor temperature should not be more than 5℃ lower than the outside temperature to avoid health impacts.
• Clean the air filters every two weeks to prevent them from becoming too dirty and wasting electricity.
• Using a ceiling fan in conjunction with the air conditioning helps distribute the cool air more evenly and allows for a slight increase in temperature to save electricity.
• About thirty minutes before the end of work, turn off the air conditioning compressor, allowing it to just circulate air, which reduces power consumption.
• Install blinds or curtains on east-west facing windows to reduce sunlight's radiant heat from entering and lessen the air conditioning load.
• Ensure that the air-conditioned area is isolated from the outside, keeping doors and windows tightly closed to prevent cool air from escaping or heat from entering.
• During consecutive holidays or when there are fewer people, try not to use central air conditioning to avoid high costs from low-load operations.
• Implement variable frequency control for the chilled water and air conditioning airflow systems to save electricity.

Here are some tips for saving electricity on lighting:

• Set lighting according to illumination standards, choosing LED lights with an appropriate lumen output; the more efficient the fixture, the less electricity it consumes.
• Select light colors that are pale or have higher reflectivity for ceilings and walls to enhance light diffusion and reduce the number of fixtures needed.
• In areas like low-light corridors, consider reducing the number of fixtures or using controlled lighting setups.
• Establish a responsibility system for different areas, turning off lights when not in use, and install daylight sensors to automatically adjust the brightness of fixtures.
• In places like meeting rooms and public restrooms, install motion sensors to save unnecessary lighting electricity.
• Regularly clean lighting fixtures to ensure that their lighting efficiency is not affected by pollutants.
• Design area control circuits for lighting fixtures, turning them on only as needed based on actual usage.
• Review the number of lights turned on and the ambient light levels to ensure the lighting is moderate and avoid glare.

Here are some tips for saving electricity with elevators:

• When there are two elevators, set them to stop at different floors; one can service odd-numbered floors while the other takes the even-numbered ones to save power.
• After three minutes of standby, the lighting and ventilation systems in the elevator should automatically shut off.
• When traveling three floors up or down, choose to walk instead of using the elevator whenever possible.
• Select variable frequency elevators equipped with regenerative power devices to improve efficiency.
• Control the cooling ventilation performance in the elevator machine room to enhance energy efficiency.

Strategies for saving electricity with appliances:

• Choose home appliances with high energy efficiency ratings and unplug them when not in use for an extended period to reduce standby power consumption.
• Purchase office equipment with energy-saving features that can automatically enter power-saving mode after 15 minutes of inactivity.
• High-voltage users should maintain voltage within ±5% to avoid increased energy consumption.
• Select high-efficiency or variable frequency motors for water pumps, and install setting controllers in underground parking lots.
• Set up an energy management system to effectively monitor peak electricity use, air conditioning, lighting, and other equipment’s energy consumption.

Simple actions can save money and contribute to environmental protection!
