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 (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.

The goal of the Annex Electric Motor Systems is to raise awareness on the large savings potential in motor systems, while showing the realization method of such a path. Currently, Austria leads the task Energy Audits for Motor Systems to develop recommendations for carrying out energy audits for motor systems based on international standards.
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 EBC Annex 61 - Business and Technical Concepts for Deep Energy Retrofit of Public Buildings
Target of IEA EBC Annex 61 was the development of technical and economical concepts for Deep Energy Retrofit of public buildings. To force high-quality and energy efficient retrofit, besides the enhancement and dissemination of innovative, technical retrofit concepts, the focus was in the development of innovative business models (energy-contracting).
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.
Clean Energy Education & Empowerment (C3E International Initiative)
The C3E TCP deals with strategies, policies and measures to increase the promotion of women in the energy sector. The aim is to create a framework in which participating countries can share information and best practices on effective strategies for the empowerment of women in this sector.
IEA EBC Annex 60: New generation computational tools for building and community energy systems based on the Modelica and Functional Mockup Interface standards
The objective was to develop and demonstrate next-generation computational tools that allow building and community energy grids to be designed and operated as integrated systems. The work conducted in Annex 60 has helped to share, further develop and deploy free open-source contributions of previously uncoordinated activities in modeling and simulation, based on the Modelica and Functional Mockup Interface standards.
