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.

EBC Annex 80 – Resilient cooling

Status: Ongoing (2018-2023)

Operating agent:

Australian participants:

Annex overview

Resilient cooling is used to denote low energy and low carbon cooling solutions that strengthen the ability of individuals - and our community as a whole - to withstand and prevent the thermal (and other) impacts of changes in global and local climates, particularly with respect to increasing ambient temperatures and the increasing frequency and severity of heat waves.

According to this definition, resilient cooling includes technologies and solutions that:

  • Reduce externally induced heat gains to indoor environments;
  • Offer personal comfort apart from space cooling;
  • Remove heat from indoor environments; and
  • Control the humidity of indoor environments.

The project is investigating resilient cooling applications against a variety of external parameters such as climate, building typologies, internal loads and occupancy profiles, various levels of BMS capabilities and automation, new buildings and retrofitting of existing buildings. Furthermore, the project is closely connected with activities such as Mission Innovation’s Challenge #7: Affordable Heating and Cooling of Buildings, the Kigali Cooling Efficiency Programme and the IEA Global Exchange on Efficiency: Cooling.

EBC Annex 79 – Occupant-Centric Building Design and Operation

Status: Ongoing (2018 - 2023)

Operating agents:

Australian participants:

ANNEX OVERVIEW

Previous research (for example resulting from EBC Annex 53) has identified the strong influence of occupants on building performance. Recently, EBC Annex 66 has provided a sound framework for experimentally studying and modelling  different behavioural actions, including the implementation of these models into simulation platforms. But, real operation of buildings shows that many such models do not represent the manifold human interactions with a building appropriately enough, and that there is no guidance for designers and building managers on how to apply occupant behaviour models in everyday practice. The purpose of this project is to provide new insights into comfort-related occupant  behaviour in buildings and its impact on building energy performance. An open collaboration platform for data and software is being created to support the use of ‘big data’ methods and advanced occupant behaviour models. It is further promoting the application of this knowledge in building design and operation processes by assisting decision making and by supporting practitioners. 

OBJECTIVES

The project objectives are to:

  • Develop new scientific knowledge about adaptive occupant actions driven by multiple interdependent indoor environmental parameters;
  • Understand interactions between occupants and building systems;
  • Deploy ‘big data’ (e.g. data mining and machine learning) for the building sector based on various sources of building and occupant data as well as sensing technologies;
  • Develop methods and guidelines and preparing standards for integrating occupant models in building design and operation; and
  • Create focused case studies to test the new methods and models in different design and operation phases.

ACTIVITIES

The planned outcomes from the project are as follows:

  • Enhanced scientific knowledge about comfort-driven occupant interactions with building technologies. This includes methodological approaches to examine multistressor effects by environmental influences on human subjects;
  • Informed insight into the potential of various data sources and sensing technologies, as well as applications of data-based methods for knowledge discovery and modelling of occupant behaviour;
  • An open collaboration platform for data and software for supporting the use of data-mining methods and tools for applications within the area of occupant behaviour;
  • A repository of advanced occupant behaviour models for digital planning environments;
  • Proposals for standards and policy support for implementing occupant behaviour simulation in building design and operation practice. This also includes the integration of the models in modern digital planning (BIM) environments; and
  • Guidelines on how to apply occupant models and occupant behaviour issues within building technologies, including user interfaces, as part of everyday design and planning processes.

EBC Annex 70 – Building Energy Epidemiology: Analysis of Real Building Energy Use at Scale

Status: Ongoing (2016-2023)

Operating agent:

Australian participants:

Annex overview

In response to concerns about climate change, energy security and social equity, governments around the world are developing plans to dramatically reduce energy demand and carbon dioxide emissions, - or in the case of emerging economies - develop in less energy intensive ways. This transformation will require a raft of technology and policy interventions that, to be truly effective, will require comprehensive empirical evaluation.

This project specifically seeks to support decision-makers and investors in their efforts to transform to a low carbon and energy efficient building stock. This is to be achieved by focusing on developing best practice methods for collecting, accessing, analysing and developing models with empirical data of energy demand in buildings and communities.

Idealised operation of a national building data and stock model. Source: EBC Annex 70.

Building energy epidemiology is the study of energy demand to improve the understanding of variations and causes of differences within an energy-consuming population. It considers the complex interactions between the physical and engineered systems, socioeconomic conditions, in addition to individual interactions and practices of occupants. The results will facilitate the use of empirical data in undertaking international energy performance comparisons, policy review exercises, national stock modelling and technology and product market assessments and impact analyses.

Objectives

  1. Evaluating the scope for using real building energy use data at scale to inform policy making and to support industry in the development of low energy and low carbon solutions;
  2. Establishing best practice in the methods used to collect and analyse data related to real building energy use, including building and occupant data; and
  3. Comparing across the national approaches to developing building stock data sets, building stock models, and to addressing the energy performance gap in order to identify lessons that can be learned and shared.

Activities

The identified set of deliverables to be achieved by participants for this project includes:

  • A registry on national building stock surveys and models (with actual data if available); and
  • A series of best practice and information reports on international data, models and methods.

EBC Annex 69 – Strategy and Practice of Adaptive Thermal Comfort in Low Energy Buildings

Status: Ongoing (2014-2022)

Operating agents:

Australian participants:

Annex overview

Reducing energy use and providing comfortable indoor environments for occupants are both key objectives of the building sector globally. However, establishing the appropriate balance between these competing issues is challenging. Is it possible to achieve thermal comfort in buildings without increasing energy use? To answer this, this project is focusing on:

  • Creating a scientifically based explanation of the underlying mechanism of adaptive thermal comfort for people in buildings; and
  • The application and evaluation of the thermal adaptation concept to reduce building energy consumption through design and control strategies.

Source: Rawal et. al, 2020Personal comfort systems: A review on comfort, energy, and economics, Energy and Buildings, Vol. 214, DOI: 109858.

The concept of adaptive thermal comfort is not new, but there are still existing problems to be solved in this field of research:

  • Although the adaptive effect has been observed by many researchers, the mechanism of the adaptive process is still unclear, especially the psychological and behavioural influences;
  • The thermal adaptation responses of people in diverse climatic regions can be quite different, which may result in different building design strategies and indoor environment solutions. Current understanding of occupants’ adaptive responses in different climate regions is still limited; and
  • Apart from purely free-running buildings or airconditioned buildings, mixed-mode buildings (cooling / heating together with natural ventilation) are actually the most common type. However, in existing standards there are no evaluation criteria for this kind of building. Most clients refuse to accept low energy building design with an indoor thermal environment outside the comfort range defined in current standards.

Objectives

  1. Establish a database with quantitative descriptions of occupant thermal adaption responses;
  2. Develop new or improved indoor thermal environment criteria based on the adaptive thermal comfort concept;
  3. Provide a basis for the creation or revision of indoor environment standards;
  4. Propose passive building design strategies to achieve thermal comfort with low energy consumption; and
  5. Provide guidelines for new cooling and heating devices based on perceived / individual control adaptation.

Activities

The identified set of deliverables to be achieved by participants for this project includes:

  • Database with a user interface including information about human thermal reactions, together with occupant behaviour and building energy consumption;
  • Model and criteria for the application of adaptive thermal comfort in buildings;
  • Guidelines for low energy building design based on the adaptive thermal comfort concept; and
  • Guidelines for personal thermal comfort systems in low energy buildings.

Working Group – Building Energy Codes

Status: Ongoing (2019-present)

Operating agents:

Australian participant:

  • Stanford Harrison, Commonwealth Department of Industry, Science, Energy and Resources

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 draft work plan for this WG can be found here.
