Photonic Cooling – Efficient cooling of buildings through the use of photonic
Within the scope of the project a photonic cooling approach was investigated and evaluated in terms of feasibility and cost efficiency for building applications. In particular cost-efficient photonic surfaces and concepts were investigated which need to have a high reflectivity in of the incident solar radiation (>97%) and a high emission coefficient within the spectral range of 8 – 13 micrometer in order to enable the emission of heat into the sky.
SUPROMED: Reprocessing and Reuse of Single Use Medical Devices in the Light of Sustainable Development Criteria - Implementation in Austria
In contrast to other countries there is currently no reprocessing and reuse of single use medical devices in Austria. Thus the potential for major ecological and economical savings remains unused. In a stakeholder dialogue, practical implementation strategies were developed to change the trend towards a sustainable value-added chain.
SYSPEQ - Systemische Lösung zum Betrieb von Plusenergiequartieren
Full-scale planning concepts for positive energy districts (PEDs) and their operation as energy communities (ECs). The focus is on the implementation in the existing building stock, especially in the area of social/non-profit housing. Financing options for renewable generation units, planning and operation of a PED (especially as an EC), marketing opportunities for surplus electricity and the development of an information and networking platform are part of this project. A special highlight is the practical proof-of-concept in Fuchsenloch, which is a social housing quarter of Sozialbau.
Energy-Sponge-Bruck (Energieschwamm Bruck an der Mur)
The aim of the exploration-study for the urban region Bruck/Oberaich "Energieschwamm Bruck" or "Energy-Sponge-Bruck" was to establish clear and stringent basics for a flexible development of the future energy system. Therefore an energy development concept as well as a cadaster for short-term implementation measures had been applied. The structured, Bruck-based approach acts as framework for a general energy-conception-method, valid for small and medium urban regions with 10,000 to 20,000 inhabitants.
IEA HEV Task 41: Electric Freight Vehicles (Working period 2021 - 2022)
So far, the transformation of freight transport remains one of the biggest challenges on the path to zero emission. The Task's main objectives are to monitor progress and review relevant aspects for a successful introduction of electric freight vehicles (EFV) into the market. Austrian pilot projects on EFV are used to exchange barriers and solution approaches in an international context, especially with regard to substitution potential, costs and energy consumption. Together with incentive systems for the market launch of EFV, this will be discussed with logistics companies, the ministry (BMK) and research institutions.
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.

The focus during the working period 2019-2020 was laid on the implementation of extended interoperability tests and innovative laboratory testing methods for decentralised energy resources. By active participation, Austria’s position and leading role on the forefront of international Smart Grids development was strengthened.
IEA-SHC Task 50: Advanced Lighting Solutions for Retrofitting Buildings
Retrofitting of non-residential buildings with energy efficient daylight and artificial lighting solutions can significantly contribute to reductions in electric energy consumption. However, appropriate technologies have to be made available to the stakeholders (investors, industry, consultants, designer) that are involved in the retrofitting process. Thus, system solutions for daylighting and artificial lighting were evaluated, simple rating and evaluation tools were developed and case studies that serve as best practice examples were monitored. The results were collected in the Lighting Retrofit Advisor, which helps stakeholders within the lighting retrofit process.
