In Sweden the most important issues referring to the Urban Building Envelopes from the1960s and 70s are today (2006):

– to maintain and repair facades, roofs and installments for water and sewage

– to save energy for heating and to transmit to renewable sources of energy

– to get rid of materials and constructions that are hazardous for health

– to improve accessibility in buildings and areas

– to make the areas and buildings more attractive and safe

Improvements of these conditions are on the agenda of national policies. In the building code it is also stated that the measures should be undertaken with respect and care for existing architectural and cultural values and characteristic features in buildings and environments. They shall be planned in participation with the residents.
