Análisis del uso de la energía eléctrica en edificios de capacitación, caso de estudio

Abstract

In the present document the Energy Systems of SECAP Central Administration Building are analyzed. As part of this study, the point of operation of these Energy Systems is found by measuring their consumption of electric energy. With the obtained results, proposals are made for energy efficiency that allow optimize the operation of the systems making them more efficient. In this way, reduction of the electric energy consumption in the monthly invoice detail, is obtained. After that, correctives action plan are implemented, and the consumption is measured through a comparison of energy after the application of this plan. The results obtained were savings of: 1392,71 kWh / month in lighting ($115,59 per month), 16,34 kWh / day in the use of elevators ($40,68 per month), 1,69 kWh / month in main water pumps ($0,14 per month) and 8,05 kWh / month in secondary water pump ($0,67 per month). The rentability obtained using the proposals is analyzed using IRR and NPV economic indicators. For this computation, efficiency proposals were projected with a durability of 10 years, considering that SECAP will apply this action plan. Obtained results for IRR (in percentage %) and NPV (in US dollars $) respectively were: 4,34% and $5410,68 for illumination, 1,01% and $8,50 for elevators, 1,45% and $8,50 for main pumps, and finally 3,57% and $28,65 for secondary pumps.
