Historic, listed, or unlisted, buildings account for 30% of the European building stock. Since they are complex systems cultural, architectural, and identity value, need particular attention to ensure that preserved, used, managed over time in a sustainable way. This implies demand retrofit solutions able improve indoor thermal conditions while reducing use energy sources preserving heritage significance. Often, however, choice implementation historic is limited by socio-technical barriers (regulations, lack knowledge on hygrothermal behaviour built heritage, economic viability, etc.). paper presents approach devised IEA-SHC Task 59 project (Renovating Historic Buildings Towards Zero Energy) support decision makers selecting solutions, accordance with provision EN 16883:2017 standard. In particular, method followed partners gather assess compatible retrofitting presented. It focuses best practices walls, windows, HVAC systems, solar technologies. work demonstrates well-balanced can exist be evaluated case-by-case through detailed assessment criteria. As main result, encourages opt tailored solve conflict between conservation performance requirements.
