The modern air conditioner was invented only in the 1920’s and it didn’t become a common home feature until the latter half of the 20th century. But, while some of us might wonder how our grandparents survived hot and steamy summers, the fact is those older homes had a few tricks up their sleeves. They were designed and built with features to help them stay cool without AC.
Airflow: In northern states, it was common to create a “stack effect” by opening windows in the basement and top floor. This generated a cool breeze through the house. Further south, before AC many homes were built on blocks, allowing breezes to flow underneath and help keep them cool all summer long.
Tall ceilings: Ceilings as high as 10, 12 and even 14 feet were common in older homes. As heat rose to the ceiling, lower areas stayed cool and comfortable. Ceiling fans—powered by electricity or elaborate rope systems—also facilitated air movement.
Transoms: A transom—a small window over a door—allowed warmer air at the ceiling to circulate up to higher floors, providing more air movement throughout the house. Transoms over exterior doors often had hinges and special hardware. This allowed easy access to open and close, helping create airflow while still providing security.
Large windows: Many older and historic homes had large, double-hung windows. Opening the top sash would allow hot air near the ceiling to escape. Opening the bottom sash, especially at night, allowed cool air to flow inside. Rooms had many windows, some as large as doors. Thick, long draperies were often used in these large windows to keep out the heat. People would “draw the drapes” to help keep a room cool without sacrificing light.
Porches: Wraparound porches offered shade from the direct sun while still allowing light to pour through windows. Screened and furnished sleeping porches were also very common. People would sleep outside to catch the cool breeze of the summer night without all the bugs. Many believed that fresh air had health benefits.
Reflective roofs: Many older homes had light-colored or silver-metal roofs made of lead, tin or copper. This was a great way to reflect heat away from the home to reduce interior temperatures. It’s quite a contrast to today’s dark asphalt shingles that can absorb a lot of the sun’s rays.
Thick walls: If you could afford them, thick brick masonry or stone walls were a great insulator and kept homes cool before AC. Walls 12 to 24 inches thick were common in the Deep South, blocking the heat from the inside as the day wore on, and providing some warmth as the evening chill set in.
While every force available in the world is searching for the 5 people in the oceangate submersible, a boat filled with mostly Syrian and Pakistani refugees sank under still “unknown” circumstances off the coast of Peloponnisos, Greece (with the coast guard present). More than 600 people drowned but guess which of the two is making headlines
