Legitimation for CESBA, Integration of CESBA in the legislation (environment, procurement, building permission)

Needs and problems addressed

  • In the 2050 strategy EC is committed to low carbon society. 20-20-20 by 2020 targets of the climate and energy policy required a number of activities defined by the climate and energy package. The buildings play important role in this field; the building sector is responsible for 40% of energy use, for generating waste and for 35% of greenhouse gas emissions. Directive 2010/31/EU EPBD Recast imposed cost optimal minimum requirements for new buildings and major renovation, and demands nZEB standard for all new buildings by 2020/2018. Directive 2012/27/EU EED aims at comprehensive energy renovation of existing buildings; with a particular target of 3% annual renovation of public buildings.
  • On top of that sustainable building is a policy target within competitive EU construction sector, which has to offer environmentally friendly, cost effective and user friendly building.
  • To facilitate the resource efficiency policy in buildings, EU agreed on implementing green public procurement (GPP) in buildings, based on transparent information on environmental impacts of the building and its components.
  • Therefore EU is aiming at development of a transparent methodology for assessment of sustainable buildings in order to support the implementation of the above policy.


  • A number of methods for assessment of sustainable buildings were developed in the last 10 to 20 years, usually they were based on energy efficiency an upgraded with other environmental, social and economic indicators; based on a bottom-up principle. More recently, the standardization within CEN/TC/350 led to a list of sustainability aspects, such as environmental, social and economic sustainability and corresponding assessment methods.
  • Building sector needs a methodology for assessment and evaluation of sustainability, where a trade-off of scientific complexity of such methods and adequate simplicity for the use in practice is necessary.
  • Further adjustment of CESBA tool with nationally identified weighting factors is a promising framework to support public and private investors on the way to early nZEB and sustainable buildings (SB).
  • Public sector in participating regions shall benefit from best practice examples of CESBA based legislation. Design and building process with support of CESBA tool will lead to “public sector being as shining example of nZEB and GPP”.
  • With a set of indicators of building sustainability and with a comprehensive list of tools and protocols for its successful implementation, CESBA tool can be integrated in a legislative support to GPP in building sector.

Transnational value

  • European public sector representatives responsible for green public procurement can learn from each other via best practice examples of integration sustainable building indicators in building legislation.
  • Transnational application of CESBA based criteria for sustainable buildings with locally relevant weighting factors.

Relevance for CESBA

  • Integration of CESBA framework in the regional building legislation will give feedback on applicability of this tool in actual green public procurement process.


  • Overview of best practice in regional legislation on GPP supported with CESBA related indicators - Comparison of examples of GPP related regulation, policies, support mechanisms and criteria
  • Local weighting factors for CESBA tool indicators - Regionally tailored determination of relevant weights
  • Integrated (sustainable) design - Phases of the design process and a challenge to integrate the CESBA generic tool in particular phases (architectural competition, design brief, initial design, building permit, detailed design, tendering, construction, commissioning, operating permit, building operation phase...).
  • Involving key stakeholders of “integrated sustainable design” - Policy makers, legislative bodies, decision makers, municipalities, developers, designers, engineers, contractors, various professionals, craftsmen, building industry, building users, financial institutions (banks, funds for incentives of SB…), professional chambers… need to be informed, trained and integrated in the CESBA supported procurement process.
  • Managing success factors - Legislative support to GPP in buildings, availability of adequate tools, data bases, benchmarks, weighting of indicators in the local context, remuneration for designers based on achieved sustainable performance, training of local authorities, architects, end-users…

Expected results and reference end users

  • Overview of good practice in GPP legislation based on CESBA framework
  • Local weighting for adaptation of transnational CESBA generic tool to regional/local environment
  • Detailed proposal for integration of CESBA framework in the design process (i.e. architectural competition with CESBA criteria or design brief containing CESBA based targeted building performance….)
