Résumé

The paper presents the studies realised on the “Portici” Houses, a part of the historic Centre of Bolzano, built at the end of the 12th century. This characteristic architectural typology is composed by a system of houses with narrow facades and a continuous arcade on the front. The serial repetition of this type of building forms a constant structure, interrupted only by a system of atria that provide daylight and fresh air to the dwellings. The surface-to-volume ratio, the dimensions of the courtyards, the presence of internal shadowing, the thermal inertia of walls and cellars, and the colour of the surface finishing have a positive influence on heating and cooling demand of the buildings. Unfortunately, more recently, the users have altered the historic energy system with roofs and
canopies to improve comfort and to protect from sun and water. This situation has completely changed the original energy and environmental behaviour. The study aims to restore the original concept and to adapt it to the modern requirements, both optimizing
energy efficiency and preserving the heritage values. This means to recognize historical transformations, users’ needs, present uses, critical points, and opportunities for the retrofit. The deeper knowledge is the starting point for defining the more appropriate retrofit actions, which include suitable technologies and systems, which are cost-effective, technically and aesthetically compatible with the value of buildings and urban settlement.
