| dc.description.abstract | The present approach aims to evaluate the technical and financial feasibility of a rainwater harvesting system for an industrial building in Northeast Portugal, considering the existing conventional roof (scenario 1) and the adaptation of a green roof to the existing roof (scenario 2). In this evaluation, the impact of the two scenarios on the water savings of the building was considered. The expected water savings were 64.47% and 59.43% for scenarios 1 and 2, respectively. Therefore, the expected reduction in the annual water bill was €3867.07 + VAT (scenario 1) and €3564.63 + VAT (scenario 2). For scenario 1, considering a reservoir of 70 m3 for non-potable purposes, such as washing the floor of the building and use in industrial machinery, and an initial investment of 41,109.13 € + VAT, the single payback is 11.29 years. The single payback for Scenario 2 largely exceeded the lifetime of the green roof. However, financial incentives could be proposed to implement green roofs in this building typology, as they are considered interesting solutions to reduce the negative externalities of industrial settlements. | por |
