Two-stage evaporative coolers can reduce the temperature of outside air by as much as 50°F (for example, from 115°F to 65°F), while delivering air that is less humid than that from a single-stage evaporative cooler.
Evaporative coolers cost only one-tenth to one-fourth as much to operate as refrigeration air conditioning and are much cheaper to buy ($400-$800). This makes them an excellent option, particularly in hot, dry areas of the country.
Swamp coolers--also called direct evaporative coolers--have long been used to provide cooling in the hot, dry Southwest. They cost less than standard air conditioners and use 60-80 percent less electricity.
Air conditioning energy usage can account for about 25% of a buildings overall energy usage. However, the cost of cooling energy can equal 50% of electrical utility expenses with the combination of peak temperatures and rates during the summer
One of the finest evaporative coolers on the market today, the Breezair combines sleek, upscale design with Seeley’s dependable solid-quality construction. The result is an unobtrusive – yet incredibly attractive – powerhouse of cooling efficiency.
First, check the insulation in your attic, ceilings, exterior and basement walls, floors, and crawl spaces to see if it meets the levels recommended for your area. Insulation is measured in R-values—the higher the R-value, the better your walls and roof will resist the transfer of heat.
ENERGY STAR® labeled roof products can help you save money and the environment by reducing your energy use. They work by reflecting more of the sun's energy back into the atmosphere, keeping your building cooler and reducing your air conditioning bills.
Choosing to incorporate energy efficiency measures in homes provides insurance against rising costs. Energy efficient technologies require less energy to operate, which reduces the home's consumption and, ultimately, the energy bill.
