Energy efficiency and HVAC systems in existing and historical buildings
Refurbishment of existing and historical buildings is a priority in many European countries. Due to the need of developing a harmonized approach focusing on historical buildings, in 2014 AiCARR (Italian Association for air conditioning, heating, refrigeration) published a specific Guidelines entitled “Energy efficiency in historic buildings” (de Santoli et al., 2014) intended for both design engineers and superintendents to support the energy retrofit actions in historical buildings.
