ARCH E: sistema de apoio à tomada de decisão em projeto de arquitetura com ênfase em eficiência energética.

Abstract

The objective of this study is the development of a support decision system in architecture design integrated to the first stages of the process, in order to facilitate the appropriation of the knowledge constructed by specilists in energy efficiency by architects. The proposed tool is intended to be used for residencial buildings located in the bioclimatic zone 2. Initially, the architecture variables with major influence on energy performance of residential buildings were defined, and through interviews with specialists its been assigned weights to variables and notes to the options they could assume. From these values, the database of the program was developed, in Python language. Throught the program it is possible to simulate a set of design situations and to visualize the predicted performance in real time throught a graph. The variables were divided into levels of complexity, in aspects related to: a) form and implantation; b) thermal envelope; and c) internal enviroments. Two residencial buildings with diferente chacarteristics and energy performance known throught computer simulation were chosen to evaluate the results of the proposed program. The comparison of the results showed small variations between the assigned scores and the comfort indexes indicated by the simulations, inferior to 10% in the wort scenarios, supporting the implementation of the support system.
