Identifying the barriers that limit the spreading of interior insulation as a solution to improve the energy efficiency of the existing building stock

Abstract

Internal wall insulation is crucial for reducing CO₂ emissions in historic buildings where external interventions are undesirable. Despite its importance, adoption remains limited. The InRenova project aims to understand and remove the barriers to this limited diffusion. An online survey targeting key stakeholders explored participants' experiences with internal insulation, challenges, materials and techniques used, and design tools. The survey revealed substantial barriers, including concerns about moisture-related damages, technical complexities in the practical implementation, and a lack of validated examples. It revealed also that although dynamic hygrothermal simulations are perceived as essential for designing effective solutions, their application remains limited. Finally, participants showed little knowledge of existing guidelines, highlighting the need for better dissemination of scientific results targeting designers
