Definition of the Indicators system !

!

!

ISDIS = system of state indicators in order to measure the state of the situation INDI = system of pressure indicators in order to measure the desequilibrium of the situation Monitoring indicators : system of assessment indicators to measure the evolution of the situation

Architecture of SD Indicators System Global SD objectives (5) SD targets (21) and key issues (50) SD indicators (ISDIS, INDI, monitoring indicators)

Sustainable Development Objectives !

!

The SD definition (Bruntland) is too general to be applied directly at any territory level : we refer to this definition but we precise the content at the building and neighbourhood level. We refer to SD principles which must be taken into account in any sustainable approach : ! economic efficiency ! social equity ! environmental wisdom ! long term / short term ! global / local ! governance

Which Global SD Objectives ? SD has been defined for existing neighbourhoods and buildings as a policy or a strategy which does : !

Preserve and enhance heritage and conserve resources, Improve the quality of local environment, Ensure diversity, Improve integration, Reinforce social life.

Comments on the systems Normative but not rigid : the indicators systems must be flexible to answer problems of cities, neighbourhoods and buildings and constitute a debate and discussion element !

!

!

For diagnosis : we can use ISDIS system but also some more indicators which are more specific for the neighbourhood and the built elements For assessment : INDI is an open model where we can modify the proposed indicators and their value on the sustainability function For monitoring : Indicators must be chosen from the priorities or stakes for the neighbourhood and its built elements; all targets are not taken into account

ISDIS system !

Indicators System : not a set of indicators but a group of indicators which must be used all together. We do not

pick up some of them

!

!

SD indicators : must cover all the fields or issues of SD : economy, social, environment, governance Indisputable indicators : correspond to the items (targets) which must be taken into account for a neighbourhood analysis : the system must give the minima of the necessary information for the analysis of a neighbourhood or a city (mediem size)

ISDIS : 65 indicators !

INDI model !

!

!

!

The INDI model is an evaluation model of the impact of urban projects or scenarios on the SD indicators. This model is a decision-aid tool for local authorities as regards urban planning and regeneration projects. The INDI model comprises 63 indicators. For each of them, the model user will measure or estimate the indicator value for the neighbourhood. This value will then be expressed in a sustainability scale ranging from -3 (non-sustainable) and +3 (sustainable). This expression is made by the model, through a sustainability function Then the model aggregates the value to provide sustainability profile for each target and objective.

SD Indicators : for what ? !

!

!

To favour discussions and negotiations between the stakeholders, municipal services, elected people, inhabitants, i.e. a relevant system for people engaged in a regeneration project to support them to work together and to take into account every dimension of the SD to be a tool of training for all actors … and governance offering a time to think together (global and local) and discuss about the fundamentals of the city planning

shared diagnosis and then empowered decision, which the fundamentals of a SD approach.
