The best house for a hot climate focuses on passive cooling: orienting it to minimize east/west sun, maximizing cross-ventilation with strategic windows and high ceilings, using shading (eaves, trees, verandas), and choosing materials like high thermal mass (brick, concrete) for drier heat or lighter materials for humid zones, all while ensuring good insulation and potentially elevating the structure. The goal is natural airflow and heat deflection, using the sun's energy to your advantage (morning sun) and blocking intense afternoon heat.
Elevated Homes
Elevating the structure helps to reduce the heat absorbed by the foundation and keeps the living areas cooler. Raised Foundations: Homes constructed on raised foundations are particularly well-suited for hot and humid climates.
Check out these 10 tips that will keep you and your house cool, save you money, and help you be kind to the earth:
Concrete, brick, tile, and thick plaster will absorb large quantities of heat and release it slowly. This “thermal mass effect” helps even out daily temperature swings. In hot climates, heat is absorbed during the day and released at night when outdoor temperatures are lower.
Understand Desert Architecture
Incorporate thick adobe or stone walls, narrow windows, and shaded courtyards to keep interiors naturally cool during blistering days and warm on crisp desert nights.
Set your thermostat to 78 degrees when you are home and 85 degrees or off when you are away. Using ceiling or room fans allows you to set the thermostat higher because the air movement will cool the room. You can save 1 – 3 percent per degree, for each degree the thermostat is set above 72 degrees.
Other hot deserts include the Arabian Desert in the Middle East, the Kalahari Desert in south-western Africa, the Atacama Desert in Chile, the Australian Desert (which covers a huge area of the country), the Thar Desert in India and Pakistan, and the Chihuahuan, Mojave, Sonoran Deserts, which all make part of the ...
The best choice for hot climates has to be clay tile roofing. It's more expensive than rubber or metal, but it does a lot better for blocking sunlight and resisting wind. Clay tile provides good insulation against the beating sun, and can save you lots of money on air conditioning.
5 best materials to wear in summer
You can use products such as vacuum Insulated panels, aerogel, phenolic foams, and polyurethane to provide insulation to the house. You can also use ThermoShield – wall putty to provide thermal resistance to the walls.
Yes, running fans is significantly cheaper and more energy-efficient than running air conditioning (AC) because fans use far fewer watts (e.g., 50-75W) to circulate air, creating a wind-chill effect that makes you feel cooler, while AC units use much more power (500-2,000+W) to actively lower the room's temperature, costing many times more per hour. Fans can cost just pennies an hour, whereas AC can cost tens of cents or more, making fans ideal for mild days or for boosting AC efficiency by allowing a higher thermostat setting.
In hot and dry climates, where evaporation rates are higher, spraying water on your roof can potentially provide noticeable cooling benefits. But, in more humid environments, where evaporation is slower, the impact is less significant.
15 Ways to Cool Down a Room Fast
While opinions vary, experts often suggest avoiding bright red, dull cement grey, and olive green, as these can deter buyers or look uninviting, with black and some neons also discouraged for heat absorption or jarring intensity, according to insights from real estate sites like Zillow and designers.
Wooden homes may be common in other parts of the country, but for a variety of reasons, many of the best desert homes are made of stucco or adobe. Stucco and adobe have many advantages over wood. Adobe's thermal mass heats up and cools down slowly.
6 Areas Of Your Home Where You Lose The Most Heat
When completely closed and lowered on a sunny window, highly reflective blinds can reduce heat gain. Horizontal slat-type blinds can also be adjusted to block and reflect direct sunlight onto a light-colored ceiling.
To stay cool and comfortable in summer, avoid fabrics like polyester, nylon, acrylic, wool, satin, velvet, and denim. These materials trap heat and moisture, leading to discomfort and body odor. Instead, choose breathable, lightweight natural fibers like cotton, linen, bamboo, or Tencel.
So, the fabrics that best protect from the sun are those with an UPF of 30 or higher. As a general rule, it is preferable to opt for synthetic and semi-synthetic fabrics, such as polyester, nylon or rayon as they have a tighter structure.
For homes in hot summers and tropical climates, prioritize lighter roof colors such as white, beige, or light gray to maximize heat reflection and energy efficiency. These colors not only keep your home cooler but also reduce the need for excessive air conditioning, saving on energy costs.
Traditional buildings in hot climates often achieve comfortable conditions without electricity. Long roof overhangs, exterior shading elements and green courtyards provide shade to buildings and reduce solar heat gains.
Both materials offer excellent heat resistance, so you may want to consider it for a countertop installation, too. Porcelain is less likely to crack under extreme heat, whereas ceramic can become damaged, cracked, or even change shape when exposed to extreme heat.
12 of the best destinations that are hot all year round
In Libya, where 90% of land is desert and just 2% gets enough rainfall for cultivation, irrigation is required to grow food. This Timelapse shows a series of center- pivot irrigation fields near the Kufra Oasis, one of Libya's largest agricultural projects.
Death Valley holds the record for the highest air temperature on the planet: On 10 July 1913, temperatures at the aptly named Furnace Creek area in the California desert reached a blistering 56.7°C (134.1°F). Average summer temperatures, meanwhile, often rise above 45°C (113°F).
