EFICIÊNCIA ENERGÉTICA E ILUMINAÇÃO NATURAL

CRITÉRIOS PARA INTERVENÇÃO EM EDIFÍCIOS MODERNOS NÃO RESIDENCIAIS DO PLANO PILOTO DE BRASILIA

Abstract

This article presents the results obtained so far by ongoing research on daylight and energy efficiency in modern non - residential buildings in Brasilia, focusing on optimizing energy efficiency and environmental quality and its influence on the preservation of modern patrimony. Its main objective is to contribute to the improvement of environmental sustainability and the preservation of architectural heritage, through interventions to improve the quality of daylight and energy efficiency of modern non-residential buildings in the Pilot Plan of Brasília. The proposed methodology combines several methods, involving the evaluation of quantitative and qualitative aspects, combining computational simulations in the evaluation of daylighting and energy consumption generated by the various conditions and combinations of architectural variables of the building. From a detailed survey of energy consumption and morphological characteristics of 240 office buildings in the central zone of Brasília, a first study based on energy simulations showed that, for 4-storey buildings, the optimization of the glass optics and the addition of sun protection could reduce the energy demand between 20% and 46%, and it is possible to achieve a zero energy balance. A model of analytical parameters is being developed that allows the use of guiding criteria for interventions in buildings with historical value for modern heritage, considering the Significance, Integrity and Authenticity aspects.
