Study of Case for Energy Efficiency in Old Buildings

Abstract

Now due to the lack of rains in Brazil, the efficient use of the electric power became an important subject. There are federal norms that regulate the production and commercialization of products that are energetically efficient. Besides the regulations, several operational and maintenance methods exist to increase the efficiency of the use of the energy. These methods can reduce the electric power losses in these equipments and to optimize the consumption. Another viable alternative for the reduction of the consumption of energy is the use of equipments energetically efficient. Using the efficient equipments, operating these same equipments correctly and promoting the maintenances in agreement with the needs, a great amount of energy can be saved. The consumers that save energy will also be reducing the amount of tributes to be paid in their electric power bills. This article makes a study on old buildings in Brazil and it analyzes through a case study, as we could save with the costs of energy of these buildings.
