Abstract

Construction materials and equipment significantly influence both the initial building cost and its long-term energy performance. This study develops a bi-objective integer programming model aimed at simultaneously minimizing construction costs and operational energy consumption. The model selects the optimal combination of materials and equipment subject to structural and budgetary constraints. A linear programming formulation is proposed and solved using QSB++. The results demonstrate that integrating cost and energy considerations into a unified optimization framework can reduce total expenses while improving the building’s energy efficiency. The proposed model provides a simple yet practical decision-support tool for designers and engineers.
