Conforto ambiental: comparativo orçamentário entre estratégias projetuais ativas e passivas ao longo da vida útil da obra

Abstract

The civil construction sector is a mean that uses several resources during its execution, whether natural or artificial, and, most of the time, current buildings do not satisfactorily meet the search for natural resources such as sunlight and the circulation of air, so active construction is widely used. The global concern with sustainability causes the need to analyze ways to obtain energy efficiency in projects and works. One of the functions of architecture is to provide environmental comfort regardless of external weather conditions. Within this theme, one can analyze the sensations related to temperature and luminosity, since both interfere in the internal environmental control of the building and consequently in the environmental comfort. With this, the choice of construction method (either active or passive architecture), choice of materials, volumetry and implementation of the work is important to analyze economic and environmental issues. Also, in addition to observing the costs throughout the construction of the work, it is important to consider the energy expenditure throughout the life cycle of the work. Thus, the present work aims to compare, with the aid of software, a single-story house project located in the capital of Mato Grosso with two proposals: a project based on active work (lighting and artificial ventilation) and another with a passive structure (lighting and natural ventilation). With this, obtain the budgetary expenditure throughout the life cycle of the work of both design proposals.
