Why are high-rise apartments easily hot?
The top floor apartment is always favored thanks to its airy and quiet view. However, in the summer, this is the largest heat-resistant area of the building. The main reason is the rise of hot air, combined with the roof and walls absorbing sun radiation all day.
In addition, high-rise apartments are often less sheltered and receive more direct sunlight than lower floors. Old buildings with poor heat insulation windows further keep heat inside longer, making the space suffocating.
According to Mr. Allan Lake - founder of Good Guys Heating, Cooling and Plumbing (USA) - "many people ignore comparing the temperature inside and outside the house. When the outside is cooler, opening windows early can significantly reduce the need for air conditioning.
Effective and economical cooling solution
To reduce heat, the first thing is to increase air circulation. Opening windows on opposite sides helps create diagonal windflows, pushing hot air out. Electric fans can also be supported if placed in the right position, even combined with ice to increase cooling efficiency.
In addition, using the air conditioner reasonably is an important factor to save costs and electricity. Users should close the door when turning on the air conditioner and only use it when really necessary.
Mr. Steve Truett - Chairman of Aire Serv (USA) - said: "Allowing the ceiling fan to rotate counterclockwise in the summer can help reduce room temperature from 4-7 degrees F, bringing a more comfortable feeling.
In addition, limiting the use of heat-emitting devices such as ovens, dryers, and switching to using energy-saving LED lights also contributes to significantly reducing heat. Close curtains during the day, especially with light-blocking curtains, which help prevent heat radiation from entering.
In the long term, residents should discuss with the homeowner about improving the heat insulation of the roof and walls. Controlling humidity with a dehumidifier is also a useful solution, helping the space to be drier and cooler on hot days.
