On a hot day, it's generally better to keep windows closed during the hottest hours to block hot air, and open them at night or early morning when it's cooler outside to let cool air in and flush out the heat, using fans for circulation and keeping blinds/curtains drawn to block sunlight. Only open windows if the outside air is significantly cooler than the inside air to prevent bringing more heat in, and use cross-ventilation if possible.
During the day, when the temperature is highest, it is best to keep the windows closed. This protects the interior from heating up. Cover your windows with blinds or curtains to reduce direct sunlight. Choose brightly coloured curtains that reflect sunlight.
It's a common misconception that turning off the AC and opening windows at night in summer is more cost-effective. But this isn't always the case. As a general rule, if humidity levels are above 65% outdoors, then it's best to keep your windows shut.
During hot weather open windows early in the morning and late evenings to create a cross breeze and allow fresh air to flow. If you open windows on opposite sides of your house air will flow through releasing trapped warm air and allowing in cooler air.
10 Simple Actions to Take to Protect Your Home from Heat
Lüften, meaning “to air” in German, simply involves opening windows and doors to replace stuffy, stale air with fresh air. Out with the old, in with the new.
1. Better Indoor Air Quality. When windows remain closed, carbon dioxide and pollutants accumulate. Opening them allows clean outdoor air to dilute and replace stale air indoors, improving oxygen levels and reducing allergens.
Reasons why There are many reasons why rich people might leave their curtains open, including: Feeling safe: They may feel more secure in their neighborhoods and have sophisticated security systems.

The findings, published in the APA Journal of Experimental Psychology, determined that people with more narrow faces, smiley upturned mouths, raised brows, closely-spaced eyes and a light, warmer complexion looked wealthier. People also associated these facial features with trustworthiness, competence and warmth.
Keep warm air out during the day and ventilate at night
Check the forecast to gauge when temperatures are starting to rise. Wait until the cooler times of the day to open windows. When they are open, you can creating a breeze in your home by opening different windows to help air to circulate.
The standard length of time and frequency to ventilate a house by opening windows is about 5-10 minutes per hour. However, the speed in which air is discharged outside a building varies depending on such factors as window size, area of the room, and type of pollutants floating indoors.
Here's the thing: It's normal for your AC to run continuously during hot summer months. You see, on extremely hot days—we're talkin' high 90s to 100s—your system needs to keep up with the incoming heat. To do that, it will run longer in order to maintain a constant, desired temperature in your home.
Open windows on opposite sides of the home during cooler times (early morning or late evening) to create cross-ventilation. Keep blinds or curtains closed during the day, especially on sun-facing windows, to block out heat. Limit the use of ovens and stoves during the hottest parts of the day to reduce indoor heat.
The best time to open windows for cooling is early morning and late evening when outdoor temperatures are cooler than indoor air temperatures.
Set up a fan aimed upward toward a ceiling vent or high window. Use a ceiling fan (on reverse setting) to pull hot air up and push it out.
But for those in the highest income brackets, the calculus is different: People with a big home can more easily get natural light and privacy, and they don't need to worry so much about heating and cooling costs. Slowly, uncovered windows have become a status symbol.
Sleeping with the window open could inadvertently trigger allergies, asthma or potentially cause illness in someone with an already-weakened immune system. But for most people, it's relatively risk free. Aim to keep your bedroom around 65 degrees with 65 percent humidity.
🔑 Many Muslim families prioritize living in areas where they have sufficient privacy. Respectful neighbors also play a big role. 🙌 In many cases, neighbors keep to themselves and don't have windows that directly face each other. 👀 And for exterior windows, curtains are often used for added privacy.
"Lüften works simply by manually opening your windows either in the morning or in the evening to release an excess build up of carbon dioxide, mold, bacteria, allergens or condensation, while also allowing oxygen back into the interior environment," Riddei says.
Cleaning once a week should become an obligation, and if you're a neat freak, even better: your home will be cleaner! Health, budget, comfort… there are many reasons to take care of the quality of your indoor air, especially by airing. Remember that 15 minutes of airing a day is enough!
Keep windows shut at night – Most spiders are nocturnal, so keep windows and doors closed while you sleep to prevent them from getting into your home at night.
During the week resting periods are traditionally between 1pm and 3pm (“Mittagsruhe” = ”midday peace”) and between 10pm and 6am or 7am (“Nachtruhe” = “night sleep”). However, specific regulations on resting periods depend on the state you are living in. But keep in mind, Germans are quite direct.
Suffice it to say when it comes to “comfort cooling” or residential A/C, we simply do not have enough hot days each summer to justify expense of installing, operating, and maintaining A/C. In Germany we need over 650 hours with a dry-bulb temperature above 26.7 degrees Celsius, or 80 degrees Fahrenheit.
Tilt Function (Ventilation Mode)
This allows for safe, indirect airflow-perfect for ventilating a room without fully opening the window. The tilt position is ideal during mild weather or when you want to keep pets and children safe while still letting fresh air circulate.
