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.
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 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.
IEA ISGAN Annex 5: Smart Grids International Research Facility Network (SIRFN). (Working period 2019-2021)
The Smart Grids International Research Facility Network (SIRFN) aims at improving the implementation of Smart Grids technologies by collaboration between smart grid testing facilities, test beds, and large-scale demonstrations. 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.
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 SHC Task 42/ECES Annex 29: Compact Thermal Energy Storage - Material Development for System Integration
The key accomplishments of the task are summarized in the following points: New material characterizing methods were investigated, a new standard for an improved DSC measurement method has been developed, a data base for PCM, TCM and sorption materials was developed and established, advances in the numerical modelling of materials, compact thermal storage systems were developed for different material applications, a tool for the economic evaluation of thermal energy storages has been developed. Also numerous joint R&D Projects and more than twenty publications arose from the IEA-SHC Task 42 networking activity.
IEA Energy Efficient End-use Equipment (4E)
The activities of IEA 4E TCP are carried out in four platforms and joint ExCo projects. The active Platforms are: Electric Motor Systems (EMSA), Sustainable Lighting and Controls (SSL), Efficient, Demand Flexible Networked Appliances (EDNA) and Power Electronic Conversion Technology (PECTA).
IEA HPT Annex 61: Heat Pumps in Positive Energy Districts
IEA HPT Annex 61 evaluates the role of heat pumps (HP) in positive energy districts (PED). Efficiency potentials of the electric and thermal energy of districts that can be unlocked with the use of HPs are evaluated in order to reach a positive energy balance. This refers to both, upgrade of waste heat and simultaneous generation of different energy use in buildings (space heating, DHW, space cooling/dehumidification) and includes self-consumption of on-site renewable electricity generation.
IEA Bioenergy Technology Collaboration Programme (IEA Bioenergy TCP)
IEA Bioenergy’s vision is to achieve a substantial bioenergy contribution to future global energy demands by accelerating the production and use of environmentally sound, socially accepted and cost-competitive bioenergy on a sustainable basis, thus providing increased security of supply whilst reducing greenhouse gas emissions from energy use.
