Eficiência energética residencial: um estudo de caso

Abstract

In an increasingly technological and developed society, it is natural to observe the growth in energy consumption, which brings an increase in waste. The use of obsolete resources and equipment, consumer behavior, lack of incentives and energy efficiency policies are among the main topics. Even more important, in industry, even with the recession, production decreases, but consumption on a large scale does not decrease, less production is produced, almost the same consumption is consumed. The work then presents a case study of energy efficiency of a residence, showing the problems encountered and proposing appropriate solutions. The most common way to solve efficiency problems is through an audit, as this will characterize, from the inspection of the installation, consumption, demand, energy billing, analyze processes, energy flow, among others, aiming reduce expenses and increase system durability in a more optimized way. After suggesting changes in consumer behavior and the replacement of some obsolete equiment, such as refrigerator, freezer, lamps and sanitary equipment, significant monthly savings were found, around 100 R$, in addition to significant savings of Water.
