Julia Simon: 我认为开窗通风是一个简单又有效的方法来降低室内温度,从而减少对空调的依赖。Dorit Aviv教授指出,室内温度有时高于室外,因为建筑物内部的设备和人员会不断产生热量。因此,在适宜的气候条件下,开窗通风可以有效地降低室内温度,达到节能的目的。 Dorit Aviv: 我发现很多人没有意识到室内温度可能比室外高。这是因为我们室内的电器,烹饪设备,以及人体自身都会不断产生热量。与其直接去调节空调的温度,不如先尝试打开窗户,让空气流通,这通常能带来意想不到的降温效果。特别是在早晨或夜晚,利用“夜间通风”的效果会更好。

Chapters
This chapter explores energy-efficient cooling methods such as opening windows for cross-ventilation, particularly during cooler morning and evening hours, and utilizing ceiling fans to improve air circulation. It emphasizes that these methods can significantly reduce energy consumption compared to air conditioning.
  • Opening windows, especially at night ('night flushing'), can cool homes effectively.
  • Ceiling fans are significantly more energy-efficient than air conditioners, reducing energy use by up to 76%.
