“…They found that designs for minimum CO2 emissions produce 1% less CO2 footprints and they are 1% more expensive than minimum cost-based designs. Furthermore, studies [7][8][9] comparing optimum designs of RC frames for minimum CO2 footprint and construction cost report that the former lead to 4-15% less CO2 emissions than then latter. They also conclude that the actual reductions depend on the cost and environmental impact ratios of reinforcing steel to concrete materials [9].…”

“…They also concluded that, in general terms, it is not appropriate to base decisions on the emissions of concrete solely on the strength of the concrete and the type of cement used, since the variations are significant. Paya-Zaforteza et al (2009) sought to describe a methodology for designing reinforced concrete structures based on the minimization of two objective functions: Embedded CO 2 emissions and economic cost. The evaluation followed the Spanish standards and the methodology was applied to six typical structures of up to 8 floors.…”

Concrete is one of most used materials in construction and also one of the main responsible for the emission of carbon dioxide, or CO 2 , in the atmosphere. Thus, in order to study ways to reduce this impact, it is important to evaluate the influence of each raw material of the reinforced concrete, as well as the phases of the life cycle in which these impacts are more relevant. This paper presents a review of recent studies related to carbon dioxide emissions of the materials of reinforced concrete. In this review, we sought to identify the phases of the life cycle of reinforced concrete most focused by researches. It was found that the cement production stage is the most contemplated in the studies, many of them focusing on the additions of complementary cementitious products, since cement is among the materials that contributes decisively to the total CO 2 emissions. The structure sizing, with the definition of concrete strength to be adopted in the design, were also extensively investigated, since these are phases in which it is identified a greater possibility of contribution, by the researchers, for the minimization of the impacts.

“…In today's world where policy is trying to regulate the environmental impacts of buildings and where BIM has become a reality in the engineers' design approach, the integration of BIM with an advanced structural optimisation algorithm seeking environmentally friendly solutions has become a necessity. [37] state that in addition to the environmentally friendly systems and materials, the reduction in CO 2 emissions should be mitigated by the implementation of efficient material use in structural systems which can be achieved through optimisation methods.…”

The present research investigates the potential for reducing the environmental impacts of structural systems through a more efficient use of materials. The main objective of this research is to explore and to develop a holistic and integrated methodology that utilises Building Information Modelling's (BIM) capabilities combined with structural analysis and Life Cycle Assessment (LCA) as well as a two-staged structural optimisation solver that achieves efficient and environmentally responsible steel design solutions. The implemented workflow utilises Autodesk Revit -BIM, Tally -LCA and Autodesk Robot -Structural Analysis. RobOpt is the plug-in that has been established using the Application Programming Interface (API) of Robot and the .NET framework of C♯, and it inherits several structural functionalities based on Robot Finite Element Method (FEM) engine. The proposed RobOpt application can be accessed via a graphic user interface (GUI) within the Robot software. The developed BIM-enabled optimisation methodology could be utilised as a design tool to inform early stage structural design solutions. A prototypical steel framed structural system under certain loads has been explored. The resulting bespoke I-beam sections from the custom genetic algorithm (GA) optimisation demonstrate that significant savingsup to 21% -can be achieved in all tested environmental indicators when compared to the standard UK catalogue of steel sections. Considering all, the proposed framework constitutes a useful and an intuitive workflow, which aims to quantify the environmental savings of structural systems by utilising, advanced computational analysis and common construction techniques.
