Example illustration of the Indoor Air Quality metric of Subtask 1

An example of Indoor Air Quality / Energy signature for low-energy residential buildings (data represented here are just for display and do not represent actual situation).

Particulate matter emissions during cooking

The figure shows the emitted particulate matter mass as a function of particle size for three different cooking processes.

Experimental setup for freezing in the AIT's climate chamber without tubing

MPEfin Heat exchangers mounted in the flow channel

Experimental setup for investigating the frosting performance of heat exchangers at low ambient temperatures

Measurement sequence: in the initial phase the thermal mass of the heat exchanger is accommodated to the tempering conditions (A to B1), and then the main frost growth takes place (B1 to B2). Afterwards, the rapid change of the heat exchanger thermal state (at air flow rate curve steepest gradient) takes place (B2), and frost creation continues until the heat exchanger is fully blocked and the temperatures do not change any more (C).

Cross-sectional image of a laser-structured and coated steel surface

The image shows an FIB cross-section of a steel surface that has been structured using laser interference and then coated with a 2D material, in this case MXene as transition metal carbide Ti3C2. The individual MXene flakes deposited in the valleys of the laser structures are clearly recognisable.

Group photo TU Vienna - Nanjing Symposium Tribology

In December 2024, the 3rd TU Wien-Nanjing Tribology Symposium was held at TU Wien with around 60 international guests on the topic of novel 2D materials and methods for reducing friction and wear. This is also the core topic of Task 12 within the AMT-TCP.

Combination of Methods used by TCP-Activities

A set of methods was developed to categorize the kind of project work that is done in the activities. The figure shows which methods are applied how often in total (node size), and which methods were frequently applied together (edge width) by activities. The color corresponds to the different method cate-gories described in chapter.

IEA-Topics, Related Activities and Working Parties

IEA-topics on level 1 (orange, node size corresponds to the official RD&D budget 2015) and TCP-activities (non-orange nodes) and related TCP-working parties (see color code in legend).

Participation of countries in IEA Technology Collaboration Programmes and Related Research Topics

Absolute (upper chart) and relative (lower chart) number of TCP-activities that countries are participating in. The color code shows how the assigned activities are related to the IEA-Topics and how the countries set their priorities with regard to the research topics (based on the IEA RD&D taxonomy).

International cooperations of Austria in context of TCP activities.

Historic Building Energy Retrofit Atlas

Starting page of the database www.HiBERatlas.com with best practice examples that show how historic buildings can be renovated so that high energy efficiency is achieved while respecting historic preservation.

Overview Task 58 for Material and Component Development for Compact Thermal Storage Systems

The figur shows the overview and contents of the IEA SHC Task 58 for material and component development for compact heat storage. The task is divided into 4 subtasks dealing with the definition of boundary conditions, development of TCM and PCM materials, test methods and component design of compact heat storage systems.

TCM Storage System Prototype in Container for integration in a single familiy house

The picture is showing a TCM storage system with 3 moduels in combination with a heat pump system and 2 m³ buffer storage installed in a container as complete storage system. The container is shipped to a single familiy housein Warsaw and installed next to the house to store surplus of solar thermal energy from summer and provide space heating in winter
