description: KPIs related with the building renovation process, which will be enabled by the digital twin approach will be identified. This will cover: - Energy efficiency and operational performance metrics - Environmental performance metrics - Waste management and Circularity metrics - Construction process efficiency metrics <em>Subtask 2.2.1 Environmental &amp; Circularity Assessment Methodology (EKO): </em>Circularity Assessment Methodology Development – Methodologies and assessment criteria for the improvement of the circularity and resource efficiency will be identified<strong>.</strong> Circular Economy Action Plan (COM/2015/0614) and 2018 Circular Economy Package will be addressed during the selection of platform methodology. Relevant quantities benchmarking metrics, and KPIs and information the required data for the dynamic assessment will be identified. Environmental Assessment Methodology Development - Assessment methodology will be compliant with the ISO 14040 series standards and the ILCD Handbook promoted by the European Commission. In addition, it will help to support the project implementation accordingly to the eco-design principles, as it is recommended in the Ecodesign Directive (2009/125/EC). The planned cradle-to-grave LCA study will be modularly built based on data gathered in the platform with a converging Material Flow Analysis approach, that allow the study of the financial equivalents of the products and services provided that will allow the Life Cycle Cost analyses approach and support the exploitation of the technology. <em>Subtask 2.2.2 Life Cycle Cost Assessment methodology through Digital Twin Platform (Leader: EKO): </em>To optimize and demonstrate the economic sustainability of the proposed concept, the Life Cycle Costing (LCC) methodology will be implemented in order to predict and assess the cost performance of the SPHERE solutions. The LCC study will follow the recommendations set in the Code of Practice on LCC published by SETAC and adapting the LCC related ISO standards developed for specific cases (e.g. ISO 15686 for building sector or the EN-ISO 15663 series for Petroleum and natural gas industries). LCC will be built in parallel to the material flow analyses methodology and functionality developed in the Task 7.1, with a capacity to analyses the whole life cycle of the building including the renovation, construction and usage of the building. The primary approach of this service will be to quantify the financial benefits of the platform within the whole life cycle. <em>Subtask 2.2.3 Social Life Cycle Assessment Methodology (Leader: VTT)</em><strong><em>: </em></strong>Complementary to the environmental and economic assessments in WP6. In this task, the social impacts of the proposed solution will be determined by means of the social life cycle assessment methodology following the UNEP/SETAC (2009). With that whole approach, the three aspects of sustainability will be covered. Following this guidelines, <strong>the result of the Task will be the a holistic sustainability assessment methodology definition, that is compliant with the digital twin based renovation process which will be later integrated as a software service within the SPHERE platform.</strong>
