Energy retrofit strategies of built heritage: using Building Information Modelling tools for streamlined energy and economic analysis.

Abstract Dynamic simulation tools are widely used in the workflow of energy retrofitting historic buildings as they contribute to development an optimised, cost-effective renovation strategy. Additionally, Building Information Modelling (BIM) applied heritage can provide a holistic platform that improves collaboration between different stakeholders involved management, restoration and energy-retrofit buildings, by facilitating data sharing project coordination. However, use BIM for is rarely implemented due emerging technical complexities regarding interoperability. In response above shortcomings, paper addresses challenges integrating a) dynamic performance analysis b) financial feasibility analysis, using Heritage-BIM (H-BIM) tools. Insights knowledge acquired through case deep building ruin condition presented. Specifically, integrated H-BIM approach was developed authors order propose efficiency upgrade measures. The improvement measures concern thermal transmission envelope, incorporation efficient heating, cooling mechanical ventilation systems, well renewable systems. economic study based on indicators, including life cycle cost (LCCA). proposed aims become useful methodological tool public authorities, assisting attraction financing mechanisms energy-upgrade stock.
