The CESBA Passport shows the values of the built environment based on the CESBA Key Performance Indicators (KPI).
How to compare the performance of buildings on transnational level
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.
Functionality of CESBA Building Passport
Beyond the usual score typical of each rating system reported on the certificate, the CESBA Building Passport informs about the performance of the construction by providing the absolute values of the CESBA KPIs (kWh/m2, Kg CO2/m2, m3, etc.). In this way it becomes possible to compare the performance of buildings assessed by different certification systems in different geographical areas.
In all CESBA harmonized systems, the CESBA KPIs have to be adopted and included in the certification system. This means that they will be calculated as part of the performance assessment of the building, and then be, on one hand, normalized with the other criteria to produce the building’s rating score, and on the other, used in the CESBA Building Passport.
The certificates issued by the different CESBA harmonized systems will have to include a transnational section with a common format to illustrate the CESBA Building Passport: to do so, the values of the quantitative and qualitative KPIs will be listed in the common CESBA part of the building certificate issued by the specific rating system. The results of the quantitative indicators will also be graphically represented on a radar chart.
Radar chart - making CESBA Key Performance Indicators visible
The chart shows the green line of the KPI values of the building and the relationship between the KPIs value and the regional standard / label standard (red line). The blue line shows the latest common Standard for Sustainability (valid from 2014-2020) agreed for the CESBA KPIs. The chart clearly shows that the closer the green line to the blue line, the more sustainable the building is. This aims to become a comprehensive graphical tool, used as an efficient element to assess the building sustainability and to communicate these factors with all the stakeholders in the design and construction process (owner, user, consultant, etc.).
The Passport is meant to express the intrinsic building properties. Thus, no one can claim ownership for it - it is available for use by any organization. It can therefore be considered as a basis for further development of any label by a third party, which can further enrich the CESBA approach.
