SENSITIVITY STUDY IN FINDING THE OPTIMAL SHAPE OF A GREEN OFFICE BUILDING

Weimin Wang, Radu Zmeureanu, Hugues Rivard

Abstract: This paper presents a sensitivity study of the optimal shape of an office building. The perturbed design parameters include window ratios, structural systems, and insulation levels. The building footprint is defined as a simple polygon with no intersection of non-consecutive edges. Thus, design variables are polygon-related parameters including the length and direction of each edge. Life cycle cost and life cycle environmental impact are two objective functions to be minimized simultaneously. The operating energy consumption is estimated with the aid of the ASHRAE Toolkit for building load calculations. Genetic algorithm is employed to solve the multiobjective optimization problem. The sensitivity study is carried out for a 1000 m 2 intermediate floor space of an office building in Montreal, with the shape of a pentagon.
