performance assessment

iiSBE workshop on urban performance assessment

iiSBE organized a small international workshop on the performance assessment of small urban areas, that took place on 17-18 January at UN offices in Paris.

The workshop included 22 invited researchers who are active in the field. Presentations covered the development of an urban assessment tool for CESBA, the Common European Sustainable Building Assessment network that is composed of 9 European urban regions, the development of URBENERE, a similar system being developed for Latin American countries and a theoretical overview by Serge Salat who has extensive experience in this field. There was also discussion of urban assessment issues. We attach the notes from the event.

  • SBTool is a generic framework for rating the sustainable performance of buildings and projects. It may also be thought of as a toolkit that assists local organizations to develop local SBTool rating systems;
  • SBTool can be used by authorized third parties to establish adapted SBTool versions as rating systems to suit their own regions and building types;
  • It can also be used by owners and managers of large building portfolios, to express in a very detailed way their own sustainability requirements to their internal staff or as briefing material for competitions;
  • The system covers a wide range of sustainable building issues, not just green building concerns, but the scope of the system can be modified to be as narrow or as broad as desired, ranging from 100+ criteria to half a dozen;
  • SBTool takes into account region-specific and site-specific context factors, and these are used to switch off or reduce certain weights, as well as providing background information for all parties;
  • Weighting is at one level and can be partly modified by authorized third parties;
  • The system is set up to allow easy insertion of local criteria and/or language;
  • It includes IDP process steps;
  • It handles all four major phases;

    • new and renovation projects or a mix;
    • up to five occupancy types in a single project;
    • handles buildings up to 100 floors in height;
    • provides relative and absolute outputs;
