PESI - Paradigm shift in urban energy systems through synergies with industry
Analysis of different options for the use of industrial surplus energies of various shapes (waste heat, waste water, waste) and renewable energy sources in the industrial sector (e.g. solar panels on roof surfaces) in adjacent urban areas, which act as an "energy sponge". Based on real consumption and availability data, a simulation model was created and opportunities for synergies were documented.

IEA HPT Task 41: Cold Climate Heat Pumps
The aim was to increase the efficiency of outdoor air heat pumps in cold climates in locations with low outside temperatures of up to -25°C. Newly developed heat exchanger concepts were tested and optimized regarding their icing behaviour. Different circuit modifications were modelled and simulation studies for low ambient temperatures were carried out.
DAKTRis - Dynamic operational behaviour of absorption chillers in Trigeneration Systems
In the present project an absorption chiller will be adapted to meet the specific requirements necessary to integrate it with the CHP unit. By means of hardware-in-the-loop measurements and dynamic system simulations, different system configurations and control strategies will be analysed under dynamic boundary conditions, optimized and evaluated.
DiRecT – Direct recycling and upcycling of titanium chips
In the project DiRecT, different new technologies will be developed and evaluated which make it possible to directly recycle the chips generated in the manufacturing process of high-quality titanium products or to produce directly from the chips near-net-shape components or improved semi-finished products (upcycling).
Existing building reconstruction and implementation of passive house components
Implementation of passive house components, systems and techniques into the practice of existing building reconstruction, in order to reduce the energy consumption as much as possible and to increase the living quality substantially. Craftspeople and planners, who are specialized in building renovation, should gain access to passive house know-how.

TU Wien, Getreidemarkt 9, 1060 Wien, AT
Within the international meeting of the IEA PVPS Task 15 "Enabling Framework for the Acceleration of Building integrated Photovoltaics (BIPV)", a workshop on "BIPV as Architectural Tool" is organized providing the opportunity to meet local PV-Architects and BIPV stakeholders.
Digital Twin of a Dynamic Hardware Emulator: Challenges and Opportunities
6. December 2022
Online, AT
To meet the new challenges and maintain the reliability of the electrical grid with increasing share of static generation, innovative solutions are required. This lecture will present digital twin development challenges and opportunities of a dynamic hardware emulator that can be used for controller hardware in the loop (CHIL) testing.
International Sustainable Energy Conference – ISEC 2022
5. – 7. April 2022
Congress Graz, Austria and Online
ISEC 2022 is a forum for research, business and energy policy. The conference focuses on Renewable Heating and Cooling in Integrated Urban and Industrial Energy Systems.
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-SHC Task 66: SOLAR ENERGY BUILDINGS - Integrated solar energy supply concepts for climate-neutral buildings and communities for the "City of the Future”
The energy supply for climate-neutral buildings is based on holistic system concepts that achieve high renewable fractions by intelligently combining technologies, sector coupling, high grid interaction and flexibilization measures. The Solar Energy Buildings Task supports exactly this development. The objective is to identify relevant stakeholders and their needs, to develop a technology portfolio and optimised integrated energy concepts and to give recommendations to policy makers and energy-related companies.
Pallets never pall - Development of the Pallet House to series-production readiness
The winning project "Pallet House" of the EU-wide competition GAU:DI in 2007 consists of 800 (used) pallets. It has been exhibited in a scale 1:1 at the Biennale in Venice 2008 and has been developed for mass production within this project. Therefore, two exemplary scenarios were developed: (temporary) construction at Vienna's Urban Lakeside in Aspern and the construction of a low-cost building in South Africa.
InnoGOK – Investigation of the energetic and ecological usability of solar radiation on urban spaces and paths
Examination of the suitability of street space or other paved or not paved surfaces in urban areas for promoting renewable heat from solar radiation. Thus offers a high potential for increasing energy efficiency and conserving resources in urban contexts. Besides, the dissipation of heat from large solar-heated surfaces promises to prevent urban heat islands.
