This study aims to evaluate energy efficiency and the viability of exchanging fluorescent lamps with LED lamps in a residence projected for the city of Catalão, Goiás - Brazil. The research method consisted of three stages: i) market research, ii) development of two lighting projects with LED and fluorescent lamps based on the Lumen Method for a pilot house in Catalan, iii) analysis of results drafting tables that showed the cost-benefit of these lamps and the environmental impact by CO2 emissions. It is noteworthy that not compared with incandescent light bulbs to be expected that they completely leave the market in 2017. It was found that it is feasible to exchange the fluorescent lamps with LED as these have a higher initial cost to purchase, but compensate this value through energy savings and high durability and significantly reduce CO2 emissions. Soon, the work contributes inserting a simple way to contribute to energy efficiency and that benefits the user himself.porAcesso AbertoEficiência energéticaAparelhos energeticamente eficientesLâmpadas fluorescentesLâmpadas LEDEmissão de CO2Energy efficiencyEnergy efficient consumer electronicsFluorescent lampLED lampCO2 emissionsArtigo10.5216/reec.v13i2.43232
