A methodological approach to evaluate structural building projects through the Environmental Economic Index Article uri icon

abstract

  • The construction industry has a relevant social and economic role and has become critical to improving global sustainability. This industry contributes significantly to global CO2 emissions due to embodied energy and operating energy. There are methodologies to assess them, but they lack integration with other variables such as safety and costs in buildings. These methodologies are complex and costly in economic and human resources, accentuated in small-scale building projects. This research proposes the Environmental Economic Index (EEI) to evaluate structural building projects and support decision-making, based on a simplified method that exchanges parametric design and project management information without requiring specialized knowledge. Its development was based on modeling different structures for the same building subjected to several operational and lateral loads, with structural concrete and structural steel; the case study was developed in San Luis Potosi, Mexico. The concrete structure with seismic actions had a better result when comparing it with the other structural alternatives; for the same loads, the concrete structures were more economical; when modifying the loads to include seismic actions, the costs had an increase that is not significant when compared with the potential losses. Concrete structures would generate lower emissions and energy consumption quantified up to the construction stage regarding environmental impacts. The contribution of this work is to develop a simplified methodology to evaluate structural projects in the design phase, which integrates economic, environmental, and safety variables and supports decision-making by designers and real estate developers.
