Ways to Keep Your Home Cool and Lower Energy Bills During Heat Waves
熱浪期間如何保持居家涼爽並降低電費
Introduction
This report explains practical methods for keeping indoor temperatures stable and reducing electricity costs during periods of extreme heat.
本報告說明在極端高溫期間，如何透過實際方法維持室內溫度穩定並降低電費成本。
Main Body
To prevent your home from getting too hot, it is a good idea to avoid using the oven. Instead, you can eat raw vegetables or use meal kits. If you must cook, experts suggest using smaller appliances like air fryers, microwaves, or slow cookers, as these release less heat into the room. Furthermore, moving your cooking outdoors using a grill or pizza oven helps keep the heat out of the house. To make these efforts more effective, you should use exhaust fans and schedule high-heat activities for the coolest parts of the day, such as early morning or late evening.
為了防止居家環境過熱，建議避免使用烤箱。相反地，您可以食用生鮮蔬菜或使用配餐組合。如果您必須烹飪，專家建議使用較小的電器，如氣炸鍋、微波爐或慢燉鍋，因為這些電器散發到室內的熱量較少。此外，將烹飪移至室外使用烤肉爐或披薩烤箱，有助於防止熱量進入室內。為了提高這些措施的成效，您應該使用排風扇，並將高溫烹飪活動安排在一天中最涼爽的時段，例如清晨或深夜。
When it comes to air circulation, using box fans depends on the temperature difference between the inside and outside. The U.S. Department of Energy recommends placing fans to blow cool air in from the shaded side of the house, while using other fans to push warm air out from the hottest side. In houses with multiple floors, it is important to ventilate the upper levels first because heat rises. However, the National Weather Service emphasizes that during a 'heat dome' event, such as the one recently seen in Delaware, air conditioning becomes necessary because fans alone cannot provide enough relief.
在空氣流通方面，使用箱型風扇的效果取決於室內外的溫差。美國能源部建議將風扇放置在房屋陰涼側以將冷空氣吹入，同時使用其他風扇將最炎熱側的熱空氣排出。對於多層建築，首先對上層進行通風至關重要，因為熱空氣會上升。然而，美國國家氣象局強調，在發生「熱穹頂」事件（例如近期在德拉瓦州出現的情況）時，空調變得不可或缺，因為單靠風扇無法提供足夠的緩解。
Finally, you can manage the cost of cooling by adjusting your HVAC settings. Increasing the thermostat by just one degree can reduce cooling costs by about 3%. Additionally, setting the temperature 7 to 10 degrees higher when you are away from home can lower annual costs by up to 10%. To maximize efficiency, keep the blower fan on 'auto' rather than 'on' to save electricity. Other low-cost measures include closing the blinds to block sunlight and reducing the use of artificial lights to lower the heat load on your cooling system.
最後，您可以透過調整 HVAC 設定來管理冷卻成本。將恆溫器調高僅一度，即可減少約 3% 的冷卻成本。此外，在離開家中時將溫度調高 7 到 10 度，每年可降低高達 10% 的成本。為了最大化效率，請將鼓風機風扇設定為「自動」而非「開啟」以節省電能。其他低成本措施包括關閉百葉窗以遮擋陽光，以及減少使用人造光源，以降低冷卻系統的熱負荷。
Conclusion
In conclusion, using a combination of small appliances, smart ventilation, and precise thermostat settings can effectively lower both indoor temperatures and energy bills.
總結來說，結合使用小型電器、聰明通風和精確的恆溫器設定，可以有效降低室內溫度與電費支出。
Vocabulary Learning
🚀 The "Precision Pivot": Moving from Basic to Professional English
At the A2 level, you usually say things like: "Do this to save money" or "Use a fan to get cool air." To reach B2, you need to stop using generic verbs and start using Functional Precision.
🔍 The Pattern Shift
Look at how the text transforms simple ideas into high-level English:
- A2 (Basic): Change the temperature B2 (Precise): Adjusting your settings.
- A2 (Basic): Stop the sun B2 (Precise): Block sunlight.
- A2 (Basic): Make it work better B2 (Precise): Maximize efficiency.
- A2 (Basic): Lower the heat B2 (Precise): Reduce the heat load.
🛠️ The "B2 Power-Up" Logic
B2 speakers don't just use "big words"; they use words that describe the exact action taking place.
1. Control Words Instead of saying "change," use Adjust. Example: "I need to adjust my schedule" (Sounds professional and controlled).
2. Effect Words Instead of saying "make it better," use Maximize. Example: "We need to maximize our time" (Sounds strategic).
3. Movement Words Instead of "put air in," use Ventilate. Example: "You should ventilate the room" (Sounds technical and accurate).
💡 Quick Bridge Tip
Next time you want to use the word "do," "make," or "get," pause. Ask yourself: "What is actually happening here? Am I adjusting, maximizing, reducing, or blocking?" That shift in thinking is the bridge to B2 fluency.
