Using the Big Bang - Big Crunch Algorithm for Rational Design of an Energy-Plus Building

摘要

Reduction of the energy consumption without compromising living standard has become very important issue in architecture, civil engineering and building industry. This problem includes numerous independent and often contradictory aspects. That indicates that a compromise between construction cost and energy efficiency should be found. The study presented in this paper has shown that choice of structural system and its elements can significantly influence the total price of a building as well its environmental impact. Since these two aspects are usually directly confronted, the decision-maker should be aware of all their advantages and disadvantages. Therefore, numerical analysis for exploring different possibilities should not be exclusive, i.e. not to provide only one solution, but to offer at least several solutions in order to enable decisionmaker to get a good insight and to make the most appropriate choice considering given situation. The methodology presented in this paper, based on multi-objective Big Bang - Big Crunch algorithm, has proven to be successful in solving this kind of problem.
