CEC5 promotes energy efficiency in central Europe through application in public buildings. The central Europe is a highly urbanized area with a huge stock of existing public and private buildings with low energy efficiency. Great efforts are necessary to overcome the problem of energy consumption. To reach the goal of a nearly-zero energy demand buildings there is a great need for new techniques, methodologies and investments. The overall objective of the project CEC5 is the promotion of energy efficiency and exploitation of renewable energy sources through application in public buildings. At EU level, the Directive 2009/28/EC on Renewable Energy Sources (RES) and the Proposal on the Recast of the Energy Performance of Buildings Directive (2002/91/EC) define the framework for related actions for the next years in the fields of RES and energy efficiency (EE). The project directly addresses all these elements in a combined way. The main outputs are described in the project result booklet.

Problems to be addressed

  • Europe-wide public buildings are the worst examples concerning energy efficiency and the use of renewable energy sources, but should also play the role models for private and industrial buildings.
  • European wide lack concerning public buildings.
  • Standardized/harmonized ecological criteria needed.
  • Specific problems in the participating countries (e.g. promotion of Nuclear Energy in CZ; SI has a lack of assessment systems etc.).
  • Except from the ENERBUILD tool, Life Cycle Cost and economic aspects are often not or too less considered.


  • To promote energy efficiency and exploitation of renewable energy sources through application demonstration in public buildings.
  • To implement a common certification procedure for eco-logical (renewable energy sources using and energy efficient) public buildings.
  • To set up sample buildings, establishing a showcase, a model for citizens: 7 CEC5 demonstration buildings in 7 EU-countries will be implemented, which demonstrate and promote energy-efficient public building.
  • To establish a transnational network to develop the ecological quality of constructions by offering certification services in the public sector. The network ensures that a continuous development and dissemination takes place.

Actions on low-carbon economy, energy efficiency and nZEBs

  • Capitalization and categorization of existing knowledge on energy efficient building
  • Definition of a baseline to energy efficient building
  • Assessment and introduction of new approaches (feasibility study, certification schema with ecological indices and life cycle costs, look at user behaviour).
  • Design of comparable grids and evaluation (simple and cost-effective rating system).
  • Compilation of study compendia in the national context and lessons from the other countries.
  • Selection of professionals that can be used as knowledge transmitters for decision-makers in the public sector.
  • Construction/rehabilitation of 7 CEC5 demonstration buildings based on jointly defined selection criteria.
  • Accessibility concept (how the building is open to the public to encourage people to sustainable building).
  • Model certification summary of 24 CESBA assessments based on the KGA from Vorarlberg.
  • Elaboration of guidelines for the transfer of the public building model to private households and office buildings.
  • Development of a joint strategy and action plan for new public buildings of low energy character, utilising the national frameworks for the Energy performance certificates.
  • Formation of CESBA Thematic Working Groups for the period beyond project implementation in order to design a Permanent Transnational Observatory platform CEC5 in the course of the project.

Main results

Increase motivation and attendance for establishing nZEBs in Europe. Transnational tool on harmonized sustainable building assessment and strategy development. Development and establishment of a permanent transnational structure for promoting a harmonized public building assessment in Europe.

Outputs developed in the project

Project strengths and weaknesses

Project strengths

Commonly developed CESBA guide including a methodology to assess buildings.

Demonstration buildings have a great visibility in the countries.

Project weaknesses

Long project duration.Non-homogenous outcomes in involved regions.

Harmonization is hardly possible due to legislation.
