Um estudo de caso de eficiência energética em um condomínio residencial

Abstract

The increase in electricity consumption and the associated costs has driven the search for alternatives that promote energy efficiency, especially in residential condominiums. This study presents an analysis of the application of energy efficiency techniques in a residential condominium, focusing on lighting systems, electric motors, and the analysis of the contracted tariff modality. The methodology adopted was based on an energy audit, which included a load survey, analysis of the consumption profile, examination of electricity bills, and technical calculations to estimate consumption and evaluate the economic feasibility of the proposed improvements. Among the alternatives analyzed, the use of occupancy sensors in the lighting system and the review of the tariff modality stand out, aiming to reduce electricity expenses. The results indicate that, although an initial investment is required, targeted interventions can gradually generate significant long-term savings. It is concluded that the adoption of energy efficiency techniques contributes to consumption reduction and to the more rational use of electrical energy in residential condominiums.
