CUSTOS E BENEFÍCIOS DA APLICAÇÃO DE SISTEMAS DE COLETA DE ÁGUA CHUVA E DE PLACAS FOTOVOLTAICAS

Abstract

Sustainability seeks to value a new lifestyle, where there is no waste of resources or environmental degradation. The capture and use of rainwater have advantages over its application mainly for uses that are considered non-potable, such as discharges in sanitary basins. Currently, with the use of available technologies, the generation of electric energy from solar radiation is acquired through the photovoltaic effect and has been in high demand due to its saving. The objective of the presente work is to analyze the costs and benefits generated proven for the use of photovoltaic plates and water reuse systems together using a hight standard condominium residence. To create the budgets, a simplified design for rainwater reuse station was analyzed, thus generating the amount of material used. With the historical data of precipitation and insolation, as well as the historical data provided by a resident of water and energy demand in the residence for a year, after collecting these data it was possible to dimension the reservoirs and the photovoltaic plates. The results obtained were satisfactory, which may provide savings of up to 120 thousand reais over 20 years for a condominium residence.
