Viabilidade de implantação de sistema fotovoltaico e de aproveitamento de água pluvial para estabelecimento assistencial de saúde a partir de critérios AQUA

Abstract

The functioning of health care establishments generates several environmental impacts. In this scenario, there are several sustainable measures that can be applied to civil construction, in order to reduce building use impacts to the environment. The goal of this paper is studying the feasibility for the implantation of Photovoltaic System and Rainwater Utilization System in a construction that houses two health care establishments, based on AQUA Certification’s criteria of performance evaluation. The method consisted of studies for the estimation of energy and water consumption, besides the measurement of the two systems and respective payback calculations. The photovoltaic system showed a satisfactory economy, which may be higher, since consumption was estimated for summer days, when there are higher energy expenditures. The two systems showed a short-term return on investment. The comparison between the results found and the AQUA Certification’s criteria showed that the photovoltaic system implantation reaches the excellent level. The rainwater exploitation system reaches only the good level, but due to the reasonable cost of installation and the short-term return on investments, the study considered interesting to implement the system regardless of the performance level achieved.
