New Challenge
Manage the dichotomy new way of building and historical heritage

High energy consumption
Conflict between preservation and
conservation measures
In Città Alta there are also a lot of churches (as the cathedral) and historical buildings used for tourism and cultural purposes (for instance museums).
Weak strategies

The City of Bergamo has already developed a series of strategies of energy conservation in the construction sector.
The objective of SEAP is to reduce the emission of carbon dioxide of 20% by 2020.
BUT… these activities focused mainly on the procedures for the construction of new building and nowadays a clear plan for sustainable renovations does not exist

. How can (historic) buildings be conserved and enhanced through energy-efficient measures?
. Which strategies can be taken to adapt (historic) buildings to new functions and user demands?
. Which options realize an optimum building quality with the least possible intervention?
