Understanding Air Conditioning Use During Heatwaves: A Balanced Perspective
A recent article published by Journal du Geek on June 30, 2025, titled “Canicule : faut-il vraiment laisser sa climatisation allumée en continu ?” (Heatwave: Should you really leave your air conditioning on continuously?) raises an important question for many facing rising temperatures. With the increasing frequency and intensity of heatwaves, understanding the most effective and responsible ways to use air conditioning is crucial. The article delves into the common practice of leaving air conditioners running constantly and explores whether this is truly the best approach.
The core of the discussion revolves around the energy consumption and potential cost implications of continuous air conditioning. While it might seem intuitive to maintain a constant cool temperature, the article likely explores the concept of thermodynamic efficiency. Air conditioners work by transferring heat from inside a space to the outside. When an air conditioner is running continuously, it’s constantly working to combat the heat entering the building from the outside and through heat-generating appliances or occupants. This can lead to significant energy usage.
However, the article also likely acknowledges the comfort and health benefits of air conditioning, especially during extreme heat. Prolonged exposure to high temperatures can be dangerous, leading to heatstroke and other heat-related illnesses. For vulnerable populations, such as the elderly or those with pre-existing health conditions, maintaining a cool environment can be a matter of safety.
The question of whether to leave it on continuously versus turning it on and off depends on several factors, which the article probably touches upon:
- Insulation of the building: A well-insulated home or office will retain cool air more effectively, meaning the air conditioner won’t have to work as hard to maintain the desired temperature. Poor insulation allows heat to penetrate more easily, necessitating more frequent or continuous operation.
- External temperature: The greater the difference between the outside temperature and the desired inside temperature, the more energy the air conditioner will consume.
- Occupancy and internal heat sources: The presence of people and heat-generating appliances (computers, lights, cooking) will increase the cooling load.
- Thermostat settings: Setting the thermostat to a slightly higher temperature (e.g., 24-26°C instead of 20-22°C) can significantly reduce energy consumption. Every degree higher can save a notable amount of energy.
- Type and efficiency of the air conditioning unit: Newer, more energy-efficient models (like those with inverter technology) are designed to cycle more effectively and use less energy.
The Journal du Geek article likely suggests that a more strategic approach to air conditioning use might be more beneficial. This could involve:
- Pre-cooling: Cooling the space before the peak of the heatwave or before you need to be in it.
- Targeted cooling: Only cooling the rooms that are being used.
- Using timers or smart thermostats: Programming the unit to turn on and off at specific times, or adjusting the temperature based on occupancy.
- Optimizing airflow: Ensuring vents are not blocked and that the unit is properly maintained.
- Supplementing with other cooling methods: Using fans, closing blinds and curtains during the hottest parts of the day, and improving ventilation during cooler times can all reduce the reliance on the air conditioner.
In conclusion, the article from Journal du Geek likely advocates for a nuanced understanding of air conditioning use during heatwaves. While continuous operation might seem like the simplest solution for immediate comfort, a more mindful approach, considering energy efficiency, cost, and the specific circumstances of the environment, can lead to both greater sustainability and more effective temperature management. It encourages readers to balance personal comfort with responsible resource management.
