IEA PVPS Task 14: High Penetration of PV Systems in Electricity Grids (working period 2014 - 2018)

The IEA-PVPS Task 14, led by Austria as Operating Agent, promotes the use of grid connected PV as an important source in electric power systems on a high penetration level where additional efforts may be necessary to integrate the dispersed generators in an optimum manner. In a number of case studies from the participating countries, the challenges and approaches in the field of distribution networks, system management and power electronics components were shown in an international context. The result being elaborate reports with targeted recommendations and required measures to significantly increase the share of photovoltaics in electricity grids.

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 SHC Task 52: Solar Thermal & Energy Economics in Urban Environments

IEA SHC Task 52 focused on the analysis of the future role of solar thermal heat in integrated urban energy systems. The potential of solar thermal applications to cover the low-temperature heat demand in future low-carbon energy systems was investigated against the background of the rapidly changing framework conditions in the energy sector. Best practice examples for the integration of solar thermal systems into urban energy systems were evaluated and documented.

IEA EBC Annex 64: Optimised Performance of Energy Supply Systems with Exergy Principles

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 51: Solar Energy in Urban Planning

The focus of IEA SHC Task 51 ‚Solar Energy in Urban Planning’ has been placed on the topic of solar energy integration in urban environment. Hereby, different international examples, options and processes for planning and implementation of solar energy measures in cities throughout the world have been screened, outlined and equipped with recommendations for further development. The core outcomes of the project address different options and possibilities for optimization of planning processes, framework conditions, tools, methods and education aiming to attain more effective and timely understanding as well as integration of solar energy in urban context.

IEA DSM Task 25 – Business Models for a more effective market uptake of DSM energy services

This task aims at the identification and development of effective business models for energy services, which lead to a sustainable growth of energy efficiency services. Therefore the various national framework conditions and contexts have been analysed, that are necessary for a successful development of such business models. Examples for start-ups and entrepreneurs have been discussed, their challenges and deficits as well as success factors in terms of capabilities/skills identified and out of these findings a web based analysis tool been developed.

IEA DSM Task 24: Behaviour Change in DSM – Helping the Behaviour Changers (Working period 2015-2017)

More than 20% of the use of energy for small consumers can be saved by changed behaviours. Past efforts to tap these potentials through DSM-interventions are not effective. The Task 24 dealt with the most important actors groups as well as tools, which support the behaviour changers in their daily work. In addition, an assessment method for DSM-interventions in the frame of the Austrian law on energy efficiency was elaborated.
