ENERGY EFFICIENCY BASED ON PROCEL CRITERIA: CASE STUDY IN A PUBLIC BUILDING

Investment in energy efficiency of buildings has been a priority issue, including in public administration. The theme is important because of the potential to combine energy savings with cost reduction, and to provide examples of good practices for society. This research aimed at identifying improvements opportunities in energy efficiency in a public building of the Sao Paulo's Justice Court. The case's data was collected in unstructured interviews and technical visits, and by examining related documentation. The data were analyzed by the label PROCEL-Edifica's prescriptive method. The envelope was characterized label D, the lighting label C and the air conditioning with label B. The building as a whole achieved label C. Some of the potential improvements identified were: change of fluorescent lamps to LEDs, changes in the lighting circuit in office rooms, use of polarized films in the windows glasses, improvement in the vertical and horizontal shading of the tower facades by the use of elements that decrease the sunlight direct incidence, such as brises. Examples of investment return time analysis were calculated, indicating potential priority in actions.
