Abstract
Thinking about solving the problem of high consumption and high cost in the electricity bill, this study
proposes to present proposals to increase the energy efficiency of the site. In this sense, it is proposed
an energy efficiency analysis of a Public Higher Education Institution in the Municipality of Manaus,
Amazonas. A building survey was performed on the appliances and components of the building's
electrical system, as well as an assessment of electricity bills to measure consumption. In order to
verify voltage, current and power, electric measuring instruments were used to elaborate proposals
aiming at increasing the energy efficiency of the site. Through the results obtained during the building
survey at the IES, it was possible to observe the anomalies of the systems and indicate proposals for
repair or replacement of equipment to increase the energy efficiency of the building. From the results
obtained from the invoice it was possible to propose a new value of demand contract and by
comparing the collected data, we identified the appliances that make the electric system less efficient,
in this case, the air conditioners. Recurring payment problems with overconsumption were
encountered. Adhering to the proposal of a new contract value with possible annual savings of R $
22,543.92 referring to the payment of the demand portion in the electricity bill. It is also proposed to
replace current lamps with LED tube lamps, reducing energy consumption by 9,122 kWh / month and
saving R $ 3,263.57 per month. As for the proposal presented for the HVAC system, given the exchange
of existing appliances for new and energy efficient, was not viable. Despite representing a reduction
of 41869.91 kWh / month, the expected investment is not paid.
