CESBA is a process towards new building and neighborhood standards in Europe.
Dozens of different building assessment systems have been implemented in Europe at international, national and regional levels in the last years.
These systems are different in methods, frameworks, physical and temporal boundaries, issues considered, number of criteria, priorities etc. This lack of conformity makes the comparison of results impossible.
A harmonization process is clearly needed at European level in the way to create a common approach to building assessment that would enforce the effectiveness of certification labels in moving the building standard practice toward a better sustainability. To achieve this objective the CESBA initiative has been launched with the involvement of more than 30 public an private European organizations form Austria, France, Italy, Spain, Czech Republic, Germany, Hungary, Poland, Slovenia, Slovakia, Switzerland, UK. CESBA is more than the assessment of sustainable buildings.
Key Performance Indicators
Key Performance Indicators (KPI) intend to be a European common base for building and neighborhood sustainability assessment. Their adoption by the regional/national assessment systems will facilitate the communication between stakeholders and the comparability of performance results. KPI will also support and facilitate the development of future assessment schemes.
Building Scale Indicators for Europe
The KPI at the European level have to be adopted by all the building assessment systems as they address the main issues of sustainable building:
- Nonrenewable primary energy use
- Primary renewable energy use
- CO2 emissions
- Indoor air quality
- Thermal comfort
- Building Life Cycle Cost
- Reused/recycled materials
- Water consumption
- Solid waste
- User involvement
- Monitoring / optimization of operation
Building Scale Indicators for European Macro Regions
Beside the KPI for building assessment systems at European level, some KpI have to be included depending on the macro regions (Alpine, Mediterranean, Central Europe, north Europe, etc.).
All macro regions:
- local materials
- Quality of the design and development of the building and site (urban environment and landscape integration)
Mediterranean and Alpine space:
- Depletion of habitats
Key performance indicators (KPI) intend to be a European common base for neighbourhood sustainability assessment. Their adoption by the regional/national assessment systems will facilitate the communication between stakeholders and the comparability of performance results. KPI will also support and facilitate the development of future assessment schemes.
The KPI at European level have to be adopted by all the assessment systems at neighbourhood scale and they address the main issues of sustainable building:
- process and planning quality
- participation and management of neighbourhood
- Total primary energy and renewable primary energy
- Exploitation of local resources: wind, biomass, sunlight
- Water management
- Social and functional diversity
- Access to public transport
- Connection to existing infrastructure
- life Cycle cost
- Cost development of buildings/neighbourhood
Reference Performance Indicators
The following indicators have to be taken as a reference in the development of the specific regional assessment tools. The number of indicators to be included in a specific assessment tool depends on its scope. The selection has to guarantee the CESBA assessment principles.
Reference Performance Indicators on Building Scale
These indicators are organized by issues: site/territory/location, process quality, and the three aspects of sustainability, i.e. Environmental Quality, Social Quality, and Economic Quality.
Reference Performance Indicators on Neighbourhood Scale
These indicators are organised by issues: environmental quality, social quality, economic quality and process quality.
The CESBA Passport shows the values of the built environment based on the CESBA Key Performance Indicators (KPI).
The score produced by a rating system is valid only for the geographical area where the building is realized, as it reflects the local priorities and construction practice. Therefore, it is impossible to set common performance benchmarks between regions. To be able to compare the performance of buildings at transnational level, it is necessary to use indicators expressed in absolute values, not scores. This is the key principle of the CESBA Passport.

CESBA Harmonised Indicators
All stakeholders move together in a specific direction. CESBA helps to define the endpoint and to measure the success in achieving the targets. The indicators play a key role in fulfilling the various aspects of the CESBA Cycle. The operative and effective use of the indicators has to be supported by Services, Training and Certification. Establishing clear targets also facilitates the dialogue with the society.
