The working group advises the IEA Committee on Energy Research and Technology (CERT) and the IEA Secretariat. It evolved from the Working Party on Energy End-Use Technologies (EUWP), which existed as an advisory body from 1981 to 2025.

Functions

• facilitating cooperation and coordination among the TCPs;
• regularly reviewing the TCPs and assessing their effectiveness to identify strategic opportunities, gaps and overlaps in the existing programme landscape, to continue successful existing programmes and to stimulate new cooperation activities;
• facilitating meaningful policy dialogue and cooperation between the governments of IEA members,
• informing the CERT about the achievements and future plans of the working group and the TCPs;
• facilitating exchange between IEA members, industry and other stakeholders,
• providing strategic guidance and supporting the IEA Secretariat in data collection, technology monitoring and analysis, and
• sharing insights and data with other relevant platforms and seeking opportunities for cooperation.

The Built Environment and Transport Working Group is divided into two workstreams:

Built Environment Workstream

• Decarbonisation of Cities and Communities (Cities TCP),
• District Heating and Cooling (DHC TCP),
• Energy in Buildings and Communities (EBC TCP),
• Energy Efficient End-Use Equipment (4E TCP),
• Heat Pumping Technologies (HPT TCP),
• Sustainable Combustion (Sustainable Combustion TCP) and
• User-Centred Energy Systems (Users TCP).

Scope

• scaling up renovation strategies for high performance and resilient buildings,
• regional transformation pathways covering the entire life cycle in the building sector, including energy and material efficiency, operational emissions, embodied carbon and the circular economy,
• building system integration, flexibility and the user perspective,
• sustainable and efficient heating and cooling strategies in buildings, including in developing countries, incorporating low-emission fuels such as LNG,
• solutions to limit the impact of growing demand for space cooling and to improve the resilience of buildings, including passive solutions.

Transport workstream

• Advanced Materials for Transportation (AMT TCP),
• Advanced Motor Fuels (AMF TCP),
• Electric Vehicles (EV TCP) and
• Fuel Cells and Electrolyzers (FCE TCP).

Scope

• Low-emission and efficient technologies for ground transport (such as electric vehicles), particularly for heavy-duty vehicles,
• Low-emission fuels such as Sustainable Aviation Fuels (SAF), ammonia, biofuels, e-methanol, e-ammonia and low-emissions hydrogen for shipping and aviation,
• supply chains, charging and other refuelling infrastructure systems for electric vehicles, and
• integration of transport and energy systems, as well as user perspectives.

Term of the working group: 2026–2028

all IEA member states

The Austrian chair and deputy delegates will be announced shortly.
