Viabilidade da implantação de soluções sustentáveis em instalações prediais: estudo de caso em edificação residencial multifamiliar

Abstract

Innovative and sustainable alternatives in civil construction are becoming more frequent, motivated by the occurrence of environmental problems that are aggravated with the use of conventional materials and construction methods. This work is a case study of the electrical and hydro-sanitary projects of a multifamily residential building, which utilizes traditional solutions. It was observed the development of alternative and less harmful solutions, whose feasibility was considered by analysing factors as implantation cost and return period. Various possibilities for change were idealized, and five of the most significant were detailed in this study: water reuse, rainwater harvesting, solar heating, replacement of fluorescent lamps by LEDs, wind power generation and photovoltaic systems. The need for implementation of each system was investigated, as well as the cost and economy related to them, in order to enable return period calculations and feasibility analysis. In this study, it was concluded that, even though some solutions have high implementation costs, their practicability may be assessed through the evaluation of the rapidity of the return period.
