Sistema de gestão energética em uma edificação pública no município de Vila Maria/RS: iluminação e climatização

Abstract

This study had as main objective to carry out a planning phase of an energy management system, through an in situ diagnosis in a public building in the city of Vila Maria, RS, in the lighting and air conditioning sectors. At work, an energy management team is set up, defined an energy policy and then accomplished the energy planning. To do this, make site visits and identify them in environments and equipment that consume energy and compared with other public buildings. From this, this study presented solutions and new technologies to reduce consumption, increase energy efficiency and provide greater visual and thermal comfort to users. With the suggested alternatives, an economic feasibility analysis of the investment was carried out, creating a cash flow for the project. Through criteria such as NPV and IRR, it was concluded that the investment is feasible, providing a significant reduction of expenses in the building. It should be noted that in addition to the economic benefits, a substitution for more efficient technologies means respect for the environment, energy security and more adequate thermal and lighting conditions. In the end, an action plan was drawn up, using a 5W2H methodology, with the purpose of defining strategies and goals to facilitate the implementation of the management system.
