IEA EBC Annexes and Working Groups

IEA EBC research is mainly undertaken through a series of research projects, or so-called 'Annexes'. Typically each Annex has a life span of three to four years, although extensions are possible if a continuing need for the activity is identified. Clear goals are set for each activity so that well defined products are generated. Publications are available for several ongoing and most completed annexes.

Working Groups are unique from Annexes, and they are set up to be able to collect knowledge on specific aspects between several countries, prepare new Annex projects or to follow-up on a completed project.

Annexes and Working Groups are structured so that each has a defined Operating Agent(s) who is responsible for the management and reporting of sub-tasks, research and publication of outcomes. Sitting underneath the Operating Agents are the participants. Participants consist of all parties who support the Annex or Working Group, and to which sub-tasks are assigned. 

Through the Council's engagement with DISER and the IEA, we have selected a list of Annexes deemed particularly pertinent to Australia, and these are listed below (alongside Operating Agents and participants for each).

There are other ongoing Annexes, for further information on these, please click here.

Working Group – Building Energy Codes

Status: Ongoing (2019-present)

Operating agent:

  • Meredydd Evans, Pacific Northwest National Laboratory 

Working Group overview

It is widely recognised that building energy codes (also known as building energy standards) are an effective policy tool for improving the energy efficiency of buildings, residential and commercial alike. However, even in communities and other jurisdictions with extensive history in this area, building energy codes are facing key issues, including:

  • A need for faster and easier methods to check the compliance of buildings with the code;
  • A need for greater reliability in the evaluation of code compliance;
  • The substantial amount of time it takes for building codes to integrate research and technology breakthroughs, limiting the energy savings potential of building energy codes;
  • The long-life of buildings and thus attending to the resulting challenge of incorporating energy efficiency into major retrofits of older buildings and the role of buildings energy codes in this;
  • The need to meet ambitious policy objectives including zero net energy construction standards, passive ventilation, etc,; and
  • The challenge of integrating various distributed energy resources including distributed solar, electric vehicles, and grid-interactive and flexible technologies.

In June 2019, the IEA EBC approved the creation of a Working Group (WG) dedicated to the consideration of building energy codes to foster stronger collaboration addressed at these issues.

Objectives

  • To enhance the understanding of impactful options and practices regarding building energy codes across different countries;
  • To provide methods for cross-national comparison that lead to meaningful information sharing; and
  • To foster collaboration on building energy code issues that leads to enhanced building energy code programs by incorporating new issues and practices.

Outcomes

The work plan for this WG can be found here.
