“…Among the common terms are alteration, adaptation, renovation, rehabilitation, refurbishment, retrofitting, restoration, reconstruction, retro-commissioning, modernization, transformation, tune-up, see for example [21,[26][27][28][29]. The use of a diverse terminology is due to the varied type and scale of buildings, the large range of actions, and the variety of reasons and motivations for making an intervention, e.g., preservation, technical, functional or social obsolescence [30,31]. Changes to buildings can range from minor repairs or re-fit with a minimum of interventions to major renovations with larger changes of the original building.…”
