|Building stock renovation is a major challenge towards a sustainable energy transition. In this context, there is a need for accurate and holistic assessment of retrofitting solutions. While Life Cycle Assessment (LCA) and Life Cycle Costing (LCC) methods are typically used to quantify the outcomes of a retrofit solution, these methods are highly depended on the accurate data, which is often not available in the design phase. The work presented in this paper demonstrates a building renovation assessment platform that follows a holistic approach and enables rapid but accurate consideration of several renovation scenarios. The innovation lies in the integration of two specialized tools, namely VERIFY and INTEMA.building, for lifecycle and energetic calculations, respectively. The integration offers a solution for the case in which no operational data are available. After the detailed presentation of the platform, the architecture and the offered functionality, a building renovation problem is considered as a demo case. A typical low-efficiency Greek building is examined while interventions are assumed, such as insulation of external wall, replacement of glazing surfaces, as well as heat pump and photovoltaic installation. Results showcase a significant reduction in lifetime CO2 emissions and primary energy of around 785 tons and 700 MWh, respectively. At the same time, the economic viability is ensured with estimated savings of 225 k€ during project lifecycle.|
