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. Within the CESBA framework, common criteria called “Key Performance Indicators” are identified. The KPI at European level have to be adopted by all the building assessment systems and they address the main issues of sustainable building.

Key Performance Indicators on building scale

  • 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

The reference life cycle stages to be taken into account when evaluating the KPIs are:

KPI (Key Performance Indicators) Procurement of products and services Implementation/construction stage Monitoring and usage Stage Deconstruction Disposal
Non-renewable primary energy use yes yes yes yes yes
Renewable primary energy sue yes yes yes yes yes
CO2 emmissions yes yes yes yes yes
Indoor air quality no no yes no no
Thermal comfort no no yes no no
Building Life Cycle cost yes yes yes yes yes
Reused/recycled materials yes yes yes yes yes
Water consumption yes yes yes yes yes
Solid waste yes yes yes yes yes
User involvement no no yes no no
Monitoring/optimization of operation no no yes no no

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)
  • Depletion of habitats
  • Biodiversity

Mediterranean space:

  • Water for irrigation

Key Performance Indicators on neighbourhood scale

A holistic approach to sustainable building assessment is only possible when the neighbourhood of the building is taken into consideration, too. The relevant KPI on neighbourhood scale are:

  • Process and planning quality
  • Participation and management of neighborhood
  • Total primary energy and renewable primary energy
  • Exploitation of local resources: wind, biomass, sun light
  • Water management
  • Social and functional diversity
  • Access to public transport
  • Connection to existing infrastructure
  • Buidling Life Cycle cost
  • Cost development of buildings / neighbourhood
