Study of Case for Energy Efficiency in Old Buildings

Abstract

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.

Estamos preocupados com o desempenho ambiental de edifícios históricos no Brasil?

“…Alterações nos materiais do envelope da edificação foram também objetos de estudo a partir da inserção de lã de rocha e lã de vidro na parte interna de coberturas e paredes e alteração de suas cores (CARVALHO et al, 2019;ESTEVES;LOMARDO, 2011). Alguns casos tiveram como foco a avaliação de alternativas ativas como a revisão de circuitos elétricos, dos sistemas de iluminação e motores (FUMAGALLI et al, 2016), a substituição de lâmpadas, e a instalação de aparelhos desumidificadores de ar, dentre outros (BORGES, 2017). O trabalho de Fernandes e Labaki (2016), de caráter menos conservador, considerou a implantação de uma chaminé solar na fachada do edifício histórico.…”
