Trying to stay cool at night in Florida is difficult. Here are some ways to do so:
“1. Choose cotton. Save the ooh-la-la satin, silk, or polyester sheets for cooler nights. Light-colored bed linens made of lightweight cotton (Egyptian or otherwise) are breathable and excellent for promoting ventilation and airflow in the bedroom.
2. Feel the freezer burn. Stick sheets in the fridge or freezer for a few minutes before bed. We recommend placing them in a plastic bag first (unless eu de frozen pizza is your fave aromatherapy scent). Granted, this won’t keep you cool all night, but it will provide a brief respite from heat and humidity.
3. Get cold comfort. Here’s a four-seasons tip for keeping utilities charges down: Buy a hot water bottle. In winter, fill it with boiling water for toasty toes without cranking the thermostat. During summer, stick it in the freezer to create a bed-friendly ice pack.
4. Be creative. If you thought fans are just for blowing hot air around, think again! Point box fans out the windows so they push hot air out, and adjust ceiling fan settings so the blades run counter-clockwise, pulling hot air up and out instead of just twirling it around the room.”

Longer lasting concrete is indeed green for it breaks down less and will need less maintenance.
“Over the past decade, researchers from Italy and the U.S. have analyzed 11 harbors in the Mediterranean basin where, in many cases, 2,000-year-old (and sometimes older) breakwaters constructed out of Roman concrete stand perfectly intact despite constant pounding by the sea.
The most common blend of modern concrete, known as Portland cement, a formulation in use for nearly 200 years, can’t come close to matching that track record, says Marie Jackson, a research engineer at the University of California at Berkeley who was part of the Roman concrete research team. “The maritime environment, in particular, is not good for Portland concrete. In seawater, it has a service life of less than 50 years. After that, it begins to erode,” Jackson says.”
The secret to Roman concrete lies in its unique mineral formulation and production technique. As the researchers explain in a press release outlining their findings, “The Romans made concrete by mixing lime and volcanic rock. For underwater structures, lime and volcanic ash were mixed to form mortar, and this mortar and volcanic tuff were packed into wooden forms. The seawater instantly triggered a hot chemical reaction. The lime was hydrated—incorporating water molecules into its structure—and reacted with the ash to cement the whole mixture together.”
