The summer is coming soon to the Northern Hemisphere. How do you plan to combat the heat? I live in a regular apartment without air conditioning, and installing a full-scale system is not an option. I wonder what my options are, and how other people are planning to deal with the issue.
Basically keeping all the windows open through the night and closing them in the morning. I also sleep upstairs directly below the roof during the colder months, but move to the ground floor in summer, where it gets much less hot.
Yep plus blackout blinds throughout the day, they massively help.
And/or blackout curtains as well. They pull double duty as an insulating layer, not just blocking light.
