About Annex 89

Annex 89 seeks to address to the following questions:

  • How could countries and jurisdictions establish whole-life decarbonisation pathways, performance targets and action plans that are clear or transparent to meet the goal of NetZ-WLC buildings before 2050 – considering science-based budgets and local context issues such as the capabilities and needs of stakeholders and decision-makers?
  • How would the national science-based carbon targets and budgets influence the implementation of planned actions to achieve NetZ-WLC compared to NDCs pledged by selected countries in the COP21 Paris Agreement?
  • How could a performance-based approach and framework support a multi-scale (from a single building to whole building stocks), multi-sectoral (i.e. life cycle based) and multi-stakeholder approach to decarbonize the building and real estate sector? And what are the outstanding research and development challenges and opportunities to support this goal at scale and with pace?
  • What methodological principles and assessment methods are suited to support the development and evaluation of actions and solutions proposed to meet NetZ-WLC buildings at multiple scales to meet the ultimate Paris goal of limiting temperature change?
  • How could these Paris-goal compatible methods that integrate operational and embodied carbon measures be applied to support life cycle based building and real estate sector decarbonization?
  • What are the range of instruments, tools, aids and data/information that key stakeholders in particular decision-making contexts (i.e., differentiated by country or region, stakeholder type and role, decision-making scale, type and purpose, etc.) need to meet their carbon targets in support of NetZ-WLC buildings? How are these instruments, aids and tools interrelated and linked with each other and with various processes and stages of NetZ-WLC building application and evaluation?
  • What are the specific drivers and barriers for the transitions to NetZ-WLC buildings, and how do these differ between different projects, initiatives and national contexts? How might the drivers best be enabled, and the barriers be overcome within the different decision-making contexts to support the uptake of NetZ-WLC initiatives?
