Consequently, this framework suggests benefitting from a combination of the different calculation approaches, which benefits from the output of the different BLCA tools, programmes, and databases, and which aims to calculate the total EE, EC, and Eco-point (environmental impact) of buildings in the case studies. The results reveal the higher sensitivity and level of confidence of this methodology (refer to the next chapter). Moreover, different of materials can be considered in the spreadsheet. This shows the flexibility of the measurement approach to include virgin (or materials, recycled materials, and eco-agro materials (including lower embodied energy and high construction performance) in design scenarios.
