The research activities in the project are accompanied and stimulated by the involvement of eight case studies. At the same time, the different case studies will allow the assessment of the developed solutions. From here an analysis will be conducted to generalize the found solutions, identify replicable factors and the context where replication is possible.

The case studies were chosen in order to represent
  • different climatic conditions
  • different utilisations
  • different epochs and degree of conservation restrictions
  • different needed/planned interventions
  • different time schedule of implementation

Public Weigh House, Bozen/Bolzano
Case Study 1

Public Weigh House, Bozen/Bolzano (Italy)

Building of Romanesque origins (13th century). Rehabilitation intervention necessary. Use: commerce, residential, (exhibition). Owner: Stiftung Südtiroler Sparkasse (foundation).

  • diagnosis & support for architecture competition
  • support during planning phase (insulation, windows, energy system)
  • transfer to concept on urban scale

Palazzo d'Accursio
Case Study 2

Palazzo d'Accursio, Bologna (Italy)

13th century nucleus, developed over centuries. Use: museum, public administration. Owner: Comune di Bologna.

  • diagnosis & NDT
  • support during planning phase (insulation, windows, HVAC, lighting)
  • transfer to concept on urban scale

Palazzina della Viola
Case Study 3

Palazzina della Viola, Bologna (Italy)

15th century, lightened by double open gallery, enriched with frescoes and painted wooden ceilings. Intervention and functional requalification planned. Use: university. Owner: University of Bologna

  • diagnosis & NDT
  • modeling
  • verification of intervention results


University library Fiolstraede Copenhagen
 Case Study 4

Fæstningens Materialegård, The Material Court of the Fortress, Copenhagen (Denmark)

Restorated in 1994-96, the main building, Building I, was brought back to its original shape of 1756. A reception building was added, and artistic decoration was performed. Currently the Material Court is being converted to public office spaces. Owners: Realia and the Cultural Authorities

The recent and ongoing restoration and pilot project of the court provides a unique material when it comes to analyse concrete results of energy and cultural heritage.

Monumental School – Innsbruck (Austria)
Case Study 5

Monumental School, Innsbruck (Austria)

Listed as one of the most important examples of early modern architecture in Tyrol (1929-1931). High heating energy demand and severe overheating problems due to large unshaded glazing areas. Air quality problem. Low thermal comfort. Objective: (energetic) refurbishment already decided, funds are dedicated, start of intervention not before end of 2010.

  • high efficient passive house windows with integrated shading
  • internal/external insulation of walls and roof
  • ventilation system with heat recovery

Warehouse City Potsdam
Case Study 6

Warehouse City, Potsdam (Germany)

Schinkelspeicher (19th century), refurbishment already completed, monitoring data available to 3ENCULT. Persiusspeicher (17th century), refurbishment planned. Use: Residential, offices, exhibition. Owner: Speicherstadt Potsdam

  • diagnosis of historical constructions
  • development of energy efficiency solutions (insulation, windows, energy system)

Industrial Engineering School Béjar/Salamanca
Case Study 7

Industrial Engineering School, Béjar/Salamanca (Spain)

Engineering School founded in 1852. Actual Building built in 1968. Built in concrete. Large facades in glass. Number of floors: 4. Orientation: West-East.

  • building monitoring 
  • energy Behaviour Simulation
  • RES Integration
  • building Management System (BMS)


Strickbau Appenzell Switzerland
Case Study 8

Strickbau, Appenzell (Switzerland)

Old Strickbau-building in Appenzell/Switzerland (17th century). “Strickbau” buildings are prevalent in most alpine regions and consist of layered wooden beams, connected at the corners for stability and typically extending somewhat from the core block.

  • analyze behaviour of wooden constructions after extreme interventions
  • use destructive analysis techniques usually not applicable on historic wooden buildings
  • realise different thermal and moisture conditions


For each case study a so called Local Case Study Teams will accompany the implementation of the project and the interventions in the historic buildings. Each LCS-Team will comprise the owner of the historic building; representatives from the local offices for the protection of historic monuments and other local bodies concerned (e.g. city council); architects and other professionals involved in the refurbishment works; local sponsors and possibly a representative of a local civil society organization committed to the preservation of cultural heritage.
