“To promote more environmentally friendly and economically efficient buildings.”

The problem

Buildings present sustainability challenges in many forms, including energy efficiency, materials use, and their requirements for maintenance and modification to meet changing demands. Many EU and governmental policy initiatives exist to promote and support sustainable construction, but there is no generally accepted system for assessing the sustainability of existing or planned buildings. The development of agreed and tested methods could assist in creating a system of certification and labelling that would bring clarity to the move towards ever more sustainable buildings.

LEnSE  Towards sustainable buildings


LEnSE will develop a system to assess the environmental and economic sustainability of buildings as a way of preparing for a labelling system to certify building sustainability standards.

The project will:

  • Identify the range of issues that must be included in the sustainability assessments of buildings
  • Develop an assessment methodology for a representative range of the key issues, and test the methodology on case studies
  • Set up a consultation network of key stakeholders to reach consensus on the methodology and to promote its incorporation into good practice in building design and construction

Contribution to policy development:

  • LeNSE will provide practical support for policy initiatives promoting sustainable construction in the building industry.
  • It will develop a methodology that could be used to develop policies for the certification and labelling of sustainability standards.
  • The project will help Build consensus among stakeholders concerning the requirements for sustainability standards and policies.
  • It will improve networking among European experts able to influence policy.
