The Key Performance Indicators (KPIs) in the ExcEED database
The ExcEED Key Performance Indicators (KPIs) will be used in the ExcEED database to quantify and benchmark the energy efficiency and the environmental quality at building and district level.
KPIs are used to measure the performance of buildings and provide easily accessible and useful information about buildings themselves and their parts. They aim to create a stable return of knowledge from different types of buildings towards building designers, energy managers and policy makers. The indicators can present to the different players easy to read and meaningful information that points towards weaknesses or strength points of a technical solution, control strategy, building system or policy.
The KPIs are particularly useful for their features. They are flexible enough to be used by different actors, multipurpose and applicable to different types of buildings. They are user friendly, easy to use and to visualise. The KPIs will be extremely useful especially for filtering data, benchmarking and clustering of buildings for specific analyses, and therefore for highlighting issues impacting future buildings.
The KPIs will be an important part of the ExcEED database, which is now ready to be populated with energy and environmental data of energy efficient (and non) buildings. Together with the KPIs, the ExcEED partners developed a set of metadata, to allow filtering the different building typologies according to the areas of interest of the users and normalisation strategies, to neutralise potential effects linked to the contest and to the time when the data were taken.
If you are willing to contribute to the population of the database, you would freely get KPIs, cluster and specific benchmark analyses. The more the data, the higher the value of the database.
The list of the 27 ExcEED KPIs is available below:
- Overall heating consumption per floor area
- Total cooling energy consumption per floor area
