Eficiência energética em iluminação análise do plano decenal de eficiência energética e estudo de caso

Abstract

Since prehistoric period, man has used intelligence to create mechanisms that reduce effort and increase comfort. By mastering the fire technique, he improved his food, lighting and security. He discovered the power of the waters, the winds and tamed animals, using the strength of horses and oxen for work. Thousands of years passed until a fact marked the history of energy: the invention of the steam engine, an energetic symbol of the Industrial Revolution. It was just over 100 years ago that electrical energy emerged, symbol of the Information Age. Through it, other forms of energy could be transformed efficiently, such as: heat, lighting and mechanical energy. Electricity is something special for the development of activities, but in view of the scarcity of natural energy resources and the increase in consumers resulting in price increases, the conscious use of energy is increasingly encouraged, seeking alternatives to improve quality. and efficiency of the energy to be supplied. With the increase in technology, and increase in consumers, the concern about the energy efficiency of the energy distribution system grows, with a view to the quality of supply and economy in the sector for the year 2029, an energy saving of 23, is expected. 1 million tons of oil equivalent, of which 16% corresponds to electricity savings and 84% to fuel savings, around 10% higher than those foreseen in the PDE 2029, in order to adequately deal with the implementation risks. For electricity savings in the year 2029, the industrial sector represents about 35% of the total, followed by the residential and commercial and public buildings sectors, which represent 20% and 16% of the total, respectively. The service sector, including the public lighting and sanitation sectors, but without the participation of commercial and public buildings, represents approximately 21% of the total. In this context, the general objective of this work is to analyze the considerations of the PEDF together with the PDE 2029 considering the guidelines, studies and uncertainties, practical application in an industrial environment, showing the energy gain, where a lighting Retrofit with reduction of the consumption, generating economic gain as a result of energy efficiency, which consists of changing from less efficient to more efficient lighting, considering the replacement depending on the areas, changing IP67 closed hermetic luminaires and changing lamps to LED, generating a total reduction of approximately 25% of the system power with reduced maintenance cost and risk reduction.
