The sun in South Louisiana can be an intense source of heat. Many of the vernacular buildings in the area have evolved in order to protect the home from the relentless sun. While many houses overcome their site and solar considerations by relying on air conditioning and modern conveniences, siting your house carefully can reduce the need for these systems and cut energy costs in the process.
Knowing how the sun moves over your particular site will enable you to design more energy-efficient and livable spaces.
If you are looking for more information on passive design strategies that use the sun’s natural energy to heat the home in the winter, you can refer to Louisiana Speaks: Pattern Book by Urban Design Associates, or Sun, Wind, and Light by G.Z. Brown and Mark Dekay. These publications also describe ways to minimize heat in the warmer season through porches, shutters, overhangs, and window placement.
