GreenDeal4Real - Improving the thermal comfort in mixed-use areas through cost-effective green infrastructure

In Vienna's 22nd district, a mixed-use construction project was used as an experimental space to simulate the effects of green structures and analyse their implementation in a real planning environment. The simulations, the planning laboratory and close cooperation with the developer made it possible to take microclimatic effects into account as early as the planning stage and to optimally compensate for the negative effects of additional sealing through greening.

CETPartnership Annual Conference 2025 - System Transition

21. - 22. October 2025
Online

The conference will explore how CETPartnership can enhance its role in supporting this evolution—across technologies, regions, and policy frameworks.

ReKEP

ReKEP relies on reusable transport containers instead of (disposable) cardboard packaging. These should be affordable, effective and flexible to use in the CEP sector (courier, express, parcel). The logistics processes involved are examined and adjustments are proposed to achieve economic, ecological and social sustainability.

IEA AMF Task 65: Powertrain options for non-road mobile machinery (NRMM)

Hydrogen drives are considered to be particularly important for energy-intensive applications in non-road mobile machinery (NRMM) applications. This will allow gaining a climate-effective contribution for decarbonisation of large construction and agricultural machinery. Based on the automotive sector H2 regulatory framework, the task is to develop the basis for the conformity requirements for hydrogen-powered mobile machinery and to identify approval strategies for highly mobile H2 refuelling suitable for construction sites.

sustAIn4Build - AI competence for sustainable building management in climate neutral cities

The objective of the project sustAIn4Build is to increase energy efficiency and sustainability in the building sector by using artificial intelligence (AI). Industry-specific training programs support Austrian companies to develop a workflow for integrating AI technologies into their processes, enabling them to develop resource-saving, cost-effective and sustainable solutions. This strengthens their competitive­ness and contributes to the achievement of European decarbonisation goals.

Fit4Klim - Fit through education for the climate

The aim of the project is to develop and test customised training courses to qualify cities and municipalities in the areas of climate change adaptation and climate protection, spatial planning, green finance, energy and mobility.

Flucco+ - Flexible user comfort in quarter-hourly CO2-neutral Positive Energy Districts (PED)

The aim of the project is to improve the planning basis for the construction and operation of energy flexible buildings in three specific areas. First the further development of existing models of thermal comfort for dynamic situations, second the quantification of future energy grid usefulness and third the holistic testing of the developed comfort and CO2 model at three potential positive energy districts (PED), taking into account the ecological assessment as well as the life cycle costs.

SmartControl - Standardized and smart control of municipal energy systems

The aim of the project is to develop a standardized and easy-to-implement procedure for communication, monitoring and control of decentralized technologies within municipal energy communities. Therefore, innovative interfaces and self-learning algorithms will be developed, which will ensure that the concept can be transferred to municipalities or neighborhoods without a great deal of data and measurement effort.

IEA EGRD-Workshop: Building Resilient and Robust Clean Energy Supply Chains - Challenges and Opportunities for a Sustainable Energy Transition

27. – 28. November 2025
JRC premises, Petten, The Netherlands

As governments and industries worldwide accelerate clean energy transitions, building resilient supply chains is crucial for economic competitiveness, energy security, and climate goals. This workshop gathers global experts to discuss innovative solutions, research priorities, and policy instruments for monitoring and strengthening clean energy technology supply chains.

IEA AMF Task 66: Online Seminar Series "Recent progress in SAF research" - Seminar #3/10

03. December 2025, 03:30 - 05:30 PM (CET)
Online, AT

This free online seminar will highlight recent developments on Sustainable Aviation Fuel (SAF) projects and perspectives.

Wiener Neustadt Climate neutral

Wiener Neustadt as a pioneering city, is making a conscious and ambitious transition towards climate neutrality. This complex transformation requires different measures. The measures shall both be developed in-house or developed by others and transferred to Wiener Neustadt. The effect of the entire bundle of measures from the different areas (e.g. governance, implementation districts, learning environment or energy, mobility, buildings, etc.) is subject to fact-based climate monitoring.

IEA Cities Task 2: Data for Urban Energy Planning (Working period 2025 - 2029)

Cities consume 60–80% of the globally produced energy and play a central role in the energy transition. However, they face challenges such as insufficient data, missing methodologies, and legal barriers. The project offers practical solutions, best practice examples, and tools for urban energy planning. The focus is on international knowledge exchange, improved data access and quality, as well as collaboration with multipliers and municipalities.

Climate Pioneer City Graz (KPS_Graz)

As an integral part of the ongoing Climate Change Mitigation Plan Graz process, the Climate Pioneer City Graz project with the Federal Ministry for Climate Action, Environment, Energy, Mobility, Innovation and Technology (BMK) will make a noticeable contribution to ensuring that the planned local processes and measures to achieve climate neutrality are implemented more quickly. This will be achieved primarily through the financing of additional climate protection experts in the city administration.

Climate neutral Wiener Neustadt 2040

Wiener Neustadt wants to develop its own vision and implementation strategy for climate neutrality by 2040 and develop it in four steps.

IEA ES Task 43: Storage for renewables and flexibility through standardized use of building mass

Thermal building mass activation uses building masses to condition interior spaces, but can also function as energy storage through targeted overheating/undercooling. This storage potential can be used for local and grid-connected renewable thermal and electrical energy (Power2Heat). The project develops new content on the construction, control and business models of such storages and disseminates it as guidelines, data and on the basis of best-practice objects that have been implemented.

Decarbonization of Cities and Communities (Cities TCP)

The Cities TCP is a joint international effort that aims to accelerate the decarbonization in cities by providing a communication platform for relevant expertise of all IEA bodies to the local scale including cities, financing institutions, utilities, service providers and building constructors. Vice-versa, the platform generates evidence-based research questions of cities needs for IEA TCPs.
