ABSTRACT
The climate emergency facing humanity has had a transforming impact on those working in engineering and urban creation. In building projects, sustainability issues are now integral to infrastructure, urban spaces and landscape. Indeed, some actors make them a priority in the design, construction and operation processes of their projects. Clients and contractors have had to rework their knowledge, concepts and action protocols to meet with the demands of sustainable development. The building sector, town planners and urban system operators, have always taken a systemic approach to projects. The presence of sustainability issues, which are often measured by performance levels, reinforces this practice. Design and evaluation tools are valuable aids for bringing stakeholders and issues together around an object to be designed. More particularly, in the sector of sustainable urban planning and sustainable buildings and structures, these tools act as a guideline that can help to create a common language as well as disseminate and create new knowledge. Elements of sustainable urban planning, such as eco-neighbourhoods and highly sustainable groups of buildings, are not yet totally stabilized. Some uncertainties remain regarding the performance of materials, the possibilities and the means of reaching certain objectives, as well as the financial and legal resources needed to do so.
