Sustainability, 2021, vol. 13, issue 21, 1-23 Abstract: This article aims to study the political, environmental and economic factors in contemporary society that influence new approaches and decision making in design in terms of carbon emissions and energy employment. These issues are increasingly influencing political decision making and public policy throughout every aspect of society, including the design practice. Managing this kind of complexity means adopting new forms of collaboration, methodologies and tools, knowledge and technology sharing. The article aims to narrate a PhD research experience grounded in academy–industry collaboration and aimed at creating a digital methodology for impact evaluation and investment planning. In particular, the digital methodology focuses on responding to international public policy for the sustainable growth of cities, in terms of footprint and energy demand, by including a holistic view of the design process made possible by the use of life-cycle assessment (LCA) procedures. To simplify the calculation, the methodology focuses on the Environmental Product Declaration (EPD) data rather than the entire LCA. The EPD is a document that describes the environmental impacts linked to the production of a specific quantity of product or service. The objective was not to create another evaluation method but to employ the EPD results in combination with parametric and computational procedures. The integration of those procedures by using visual programming and scripting allowed the calculation of Embodied Carbon and Embodied Energy and created a user-friendly interface to query the results. The output obtained included automatic and dynamic diagrams able to identify impact scenarios in terms of CO 2 emissions and MJ of embodied energy after the conceptual design stage. The strategic use of the charts lies in their potential to simulate impact conditions and, therefore, in the chance to create sustainable transformation scenarios in the early stages of design. At this point, the influence on choices is at its highest, and the costs are low. Moreover, the methodology represents a platform of collaboration that potentially increases the level of interaction between the actors of the construction process with the consequent improvement in design quality. In conclusion, building the design methodology and testing its performance within a specific sociotechnical context was important in critically evaluating certain topics, for example, the recent European strategies on new technology to reach sustainable objectives, the role of digital tools in proposing solutions towards contemporary social issues, the birth of new forms of partnership and collaboration and the new possibilities coming from digital evaluation approaches.
