The increase in the global population and the ever-increasing development of cities have given rise to various challenges to be overcome in environmental, social, cultural and economic terms. This situation makes it important to encourage the use of new technological solutions to build more sustainable cities and the real estate market has an important role in this process, because the incorporation of sustainable practices into buildings is decided upon during the design of real estate developments. With respect to the Brazilian market, the managers of developers currently bear the responsibility of being the decision-makers on the use of sustainable building systems and on the reduction of energy consumption over the lifespan of buildings. On the other hand, within the real estate market in the city of Rio de Janeiro, it is unusual to find multi-family housing developments that already feature such solutions integrated from the beginning into their designs, thereby demonstrating that real estate developers and buying customers overlook resource management during construction. Notably, financial considerations govern market relations and it is supposed that the implementation of sustainable solutions is still an unknown variable in terms of financial results, since the probable increase in the cost of initial construction still does not lead to visible, immediate gains for real estate developers. In addition, consumers do not have clarity on the gains tied to acquiring sustainable buildings. Information is lacking on the benefits in ecological terms and mainly, in financial terms, relating to the reduction in operating costs from the use of energy and natural resources during the lifespan of the building.
