MULTICRITERIA EVALUATION OF URBAN
The LCA (Life Cycle Assessment) method can be used to factor sustainable development requirements into construction projects, and is increasingly being applied at single building scale. Building a sustainable city, however, calls for a broader approach involving assessment of the overall environmental, economic and social impacts of projects on a wider scale: urban block initially, and then district and territory
LCA can be used to quantify an urban project’s impact on its environment, from production of the materials used to construct the built framework and infrastructure all the way through to demolition at the end of its useful life, and also including maintenance and the various potential uses.
The aim of this project is to develop a new methodology that is both multicriteria (including environmental, economic and social criteria) and “consequential”, in that it endeavours to take into account the impacts of an urban project on wider systems such as transport infrastructure, energy production systems, water production and treatment and waste treatment systems, over different time horizons.
- A calculation tool combining long-term forward simulation of the impacts of initiatives or projects at district or territory scale, to serve as a decision aid
- Territorial diagnosis and territory performance monitoring methodology
- Development of an “Efficacy Insight” seal of approval, certifying the scientific rigour of an urban project’s performance measurement
