Abstract
The theme of the design of environmentally sound low-energy architectures is current, combining first-rate formal quality and expressive coherence to high performances as regards to functional adequacy and comfort and with a minimum impact on ecosystem resources along all the life-cycle. The paper focuses on issues related to environmentally-friendly design criteria for high energy-efficient buildings, both by theoretical and applied approaches, highlighting the relationships among design choices at different scales of definition, construction process elements and performances of historical buildings. The Italian building heritage is not generally energy-efficient. Not only the historic one of which it is necessary to preserve the morphological characteristics, but especially the latest one, built from the Second World War to today. Strategies to upgrade buildings heritage define the priority objectives to be pursued. To schedule the stages of retraining, it is essential to have the global vision of the issues and to control them. The energy recovery of historical buildings should be compatible with the preservation and protection of historical, artistic and morphological characteristics of the context. On the other side, buildings without morphological quality, located in suburbs or not historical urban areas, and residential housing need of energy renovation actions, including integration and replacement of construction elements, aiming to morphological and functional restructuring.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
