Probing for a new, simple, cost-effective and building-integrated PV facade system made of plastic PV modules through initial investigations for fixing technology, for building physics, for fire protection and for electrical engineering concerning the usability, the areas of applicability and the yield and application potentialfor new buildings and for existing buildings.
Hemp Ski, Recyclable ski manufacturing from hemp, bio-resin and waste streams
In industrial production for alpine skis, epoxy resins of fossil origin and pre-impregnated glass fiber reinforcements are processed today. Innovations that replace environmentally critical materials in skis with biogenic substitute materials with an improved environmental balance have so far been limited to the production of small series. This circumstance motivated the consortium to develop a solution for a circular bioeconomy with the HempSki project, which will also make industrial ski production from renewable raw materials and waste streams possible in the future.
Eco.District.Heat - Potentials and restrictions of grid-bound heating systems of urban areas
Aim of the project Eco.District.Heat is to provide strategic decision-making support that enables Austrian towns and cities to deal with aspects of grid-bound heating (and cooling) systems in accordance with integrated spatial and energy planning from a holistic perspective when elaborating urban energy concepts.
EnErGy Plant Weiz - Renewable energy community Business Park Energy Lane and Factory Lane Weiz
Based on the results of the exploratory study project REC-Businesspark, a demonstrator for a "renewable energy community business park" is to be developed in Weiz. The focus is on the development of innovative operating and tariff models for a redox flow storage system that is integrated into a renewable energy community.
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.

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).
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).

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”
