The role of hybrid systems in the decarbonization of residential heritage buildings in Mediterranean climate. A case study in Seville, Spain

Residential heritage buildings in the Mediterranean region face unexpected challenges in the field of energy efficiency and indoor environmental quality to ensure the sustainable conservation of historic town centres. This paper evaluates whether the conservation of their values can coexist with the...
