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

October 8, 2012 8

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

The applied solutions have to be customized for the different buildings and needs, in order to integrate them with the landscape and don’t be aesthetically invasive

Questions

. 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?
