IEA EBC Annex 91: Open BIM for Energy Efficient Buildings

Building Information Modeling (BIM) is considered a key technology for optimising the overall energy performance of buildings. The project lays the foundations for OpenBIM tools to include the assessment and optimisation of the energy efficiency of buildings in the future, for Open BIM processes and data models to be increasingly harmonised and standardised, and thus for smaller construction companies to have the opportunity to work on complex BIM projects in the future.

IEA HEV Task 45: Electrified roads (E-roads)

Electric vehicles can be charged stationary as well as dynamically while driving on so-called "e-roads". From a systemic point of view, this technology can be an addition to stationary charging and is not competing. Internationally, the academic and political discussion in this field is progressing rapidly. Task 45 aims for a mutual knowledge exchange, a joint understanding of next steps and a contribution of the Austrian position into the international debate.

IEA HPP Annex 47: Heat Pumps in District Heating and Cooling Systems

A significant use of alternative heat sources with the help of district heating and cooling networks is a major challenge for a sustainable energy supply. In times of increasing shares of fluctuating producers such as PV and wind energy, the relevance of heat pumps increases. Within the framework of the IEA HPT Annex 47, potentials and barriers for the integration of heat pumps in DHC networks were analyzed.

IEA DHC TS5 - Integration of Renewable Energy Sources into existing District Heating and Cooling Systems (RES DHC)

The expansion of sustainable district heating/cooling is an essential part of the Austrian heat transition. The transformation of these supply systems to fully renewable systems requires the combination of a multitude of aspects. The aim of the project is to compile a data and knowledge base from international projects in this context. Expertise and process know-how for the process of implementing the transformation of district heating and cooling systems will be collected and processed.

IEA DHC Annex XIII Project 02: MEMPHIS 2.0 - Advanced algorithm for spatial identification, evaluation of temporal availability and economic assessment of waste heat sources and their local representation

The identification and integration of waste heat sources is a key measure towards the decarbonisation district heating networks (DHN). Aim of MEMPHIS 2 is to develop an improved algorithm for identification of different current and future waste heat sources; including time relations of the heat emitted and techno-economic details as well as the further development of the online waste heat explorer.

IEA DHC Annex XIII Project 07: CASCADE - A comprehensive toolbox for integrating low-temperature sub-networks in existing district heating networks

The majority of urban district heating networks operate at high temperatures, which are a barrier to the efficient integration of heat sources such as solar, geothermal, ambient or low temperature waste heat. CASCADE is investigating the integration of low-temperature networks into the return pipe of existing district heating networks, which will reduce return temperatures and thus improve efficiency and increase its capacity to connect new customers.

IEA EBC Annex 64: Optimised Performance of Energy Supply Systems with Exergy Principles (Working period 2014-2018)

To reduce CO2 emissions in cities, an overall understanding of energy conversion processes is necessary, which also takes temperature levels into account. This is particularly important when alternative heat sources such as waste heat, ambient heat, solar and geothermal energy are to be used, as these often have a low temperature level, i.e. a low exergy content. Accordingly, urban energy systems are analysed and optimised within the framework of the IEA EBC Annex 64 with the help of the exergy approach.

IEA DHC Annex TS7: Industry-DHC Symbiosis - A systemic approach for highly integrated industrial and thermal energy systems

Renewable and excess heat sources are currently representing nearly a third of the energy supply used in the DHC sector. Excess heat has the potential to further grow to become an important part of the energy puzzle. Up to 25% of district heating could be covered by industrial excess heat and more than 10 % of the EU's total energy demand for heating and hot water could be covered by heat from data centres, metro stations, service sector buildings, and waste-water treatment plants.

IEA ISGAN Annex 3: Benefit/Cost Analyses and Tools of Smart Grids

Together with experts from 11 countries, the EI-JKU has analysed cost-benefit models and developed proposals for their adaptation and further development. In the course of the work, the EI-JKU dealt in particular with two questions: how such an evaluation model can be adapted to Austrian conditions and which socio-economic factors influence the question of whether an end consumer emerges as a winner or loser from Smart Grid-based functionalities.
