Abstract

Nowadays, one of the most talked about topic is sustainability. Therefore, products that involve concepts such as ecological and sustainable are emerging in the market, as a way to harm the environment in a smaller scale. However, plenty of this systems have a more expensive cost duo to the technologies used in the manufacturing process, which end up making more expensive constructions. The goal of this paper was to analyze the initial costs and over time, generated with the insertion of some sustainable systems in a constructions. Thereunto, it was made the budget of a constructions of approximately 50 m², for the county of Toledo, in the state of Paraná, considering conventional and sustainable situations, analyzing expenses with water and energy for a period of 10 years for both situations. As a result, sustainable budget presented an initial cost of 11,82% greater than conventional budget. Performing the analysis over time, for photovoltaic plates, rainwater caption, LED lighting and dual flush, it was concluded for the analyzed residence, the sustainable budget would still present a higher cost of 8,16%. However, although the initial investment is greater than the savings generated over time, the monthly reused water provides savings in potable water that is increasingly scarce in the world, as well as the use of sustainable systems represent a way to preserve the environment.
