Effective contribution of structural engineers to green buildings and sustainability

Structural engineers are key players in architectural or civil infrastructure projects. However, their contribution seems to be limited in sustainability rating systems. This review analysed the credits available in the Leadership in Energy and Environmental Design green building rating systems related to the structural aspects. It concluded that the points related to the structural aspects are proportional to the cost of structural elements in a building. Embodied and total energy requirements of typical buildings were examined and it was determined that the embodied energy in the structural components has a share ranging from 2% for traditional buildings to 25% for net zero buildings. Structural strategies that can enhance sustainability but are not included in the rating systems were discussed. Enhancing structural resilience to natural and man-made disasters will be the most significant contribution of structural engineers to sustainability
