SUSTENTABILIDADE NO AMBIENTE CONSTRUÍDO

ANÁLISE DE VIABILIDADE PARA IMPLANTAÇÃO DE ESTRATÉGIAS ATIVAS

Abstract

The objective of this paper is to present an architectural exercise about a hybrid building based on the theories of Densification, Compact city, Smart cities and Multifunctional urban architecture, designed for the rational use of natural resources, taking into account their energy and water demand through active strategies. The method of this work is divided into three main steps: (1) use of natural resources as a design guideline; (2) use of computational simulation as a feedback to the iterative process of mass study evolution; (3) estimation of operating costs on water and energy demand, and possibilities to address these demands through systems implemented in loco. From the analysis of the potential of energy generation by PV panels, it was found that an area larger than the area available for the installation of this system in the project would be necessary, since it generates only 69% of the estimated energy demand. The same is true for the water demand and the area available for wetlands implantation, which can handle only 59% of the waste water from the building. Nevertheless, the potential for utilization of natural resources is observed even in a situation of occupation of a highly urbanized region, demonstrating its feasibility in reducing the costs of operation of the building through passive and active strategies, minimizing its environmental impact throughout its lifespan.
