ISCA Working Groups are key forums for individuals from member organisations to work out collaboratively the challenges and opportunities for infrastructure sustainability and the IS rating scheme. Working groups are made up of individuals who volunteer their time, expertise and capability.

ISCA Working Groups' general objectives are to:

  • inform, scope and identify future infrastructure sustainability development areas 
  • identify and resolve effective ways IS rating scheme can be utlised in various projects and organisational scenarios, and
  • inform the future of infrastructure sustainability and IS rating scheme 

Members of working groups may participate 

  • for professional development
  • to gain leadership experience 
  • to contribute to the implementation and further development of industry initiatives
  • to be at the forefront of infrastructure sustainability
  • for networking opportunities

Working groups meet regularly either by face to face or by teleconference/webinar. Working groups members are expected to participate in these meetings and undertake small amounts of work outside of the meeting, typically a few hours a month. Working groups are supported by ISCA staff members and will be provided with necessary resources.
