Energy Renovation of Listed Buildings
Abstract
Energy renovation often includes adding an insulating layer to the building envelope either on the exterior or the interior. The positive effect of this is well documented, and in many cases reducing the heat loss by a better insulating and tighter building envelope is a reasonable solution. However, the design scope of energy renovation should be constantly challenged in order to attract the interest of investors, architects, designers and, last but not least, local authorities involved with the preservation of cultural heritage in our cities. When renovating any built environment, subjective factors such as aesthetics and spatial quality should be included to provide robust solutions that achieve more than just a reduction in heat loss.
