In most homes in the southern United States, the level of insulation found is adequate for achieving an energy efficient home. However, air leakage and duct leakage are typically high, resulting in high energy bills, comfort problems, and poor indoor air quality.
The U.S. Department of Energy has announced it will invest up to $14million in R&D projects for energy efficient technologies designed to help reduce energy loads, save money and create a greener future.
Spray foam insulation can be used in hot, humid climates such as those in the southern states of the USA just as effectively as homes in northern, colder climates. One architect firm from Austin, Texas has identified some tips other architects can consider when designing for hot, humid climates.
Hot or warm climates like the southern states of the USA can benefit equally as well as their northern counterparts from spray foam insulation. In fact, one area of the typical family home that can benefit from spray foam insulation is the unvented attic.
