IEA EBC Working Group on Cities and Communities (WGCC)
The WGCC enables information and experience exchange, the identification of bottlenecks that lead to specific research questions and a direct communication with cities on their needs, to enable them to transform their energy systems. The working group is a joint initiative across several TCPs with in-depth participation of technical and non-technical (external) experts.

IEA SHC Task 61/EBC Annex 77: Integrated Solutions for Daylighting and Electric Lighting
Lighting accounts for around 15% of global electricity consumption - intelligent coordination of daylighting and electric lighting solutions together with integral lighting controls enable significant energy savings. At the same time, the solutions must be optimally planned in a user-centered approach based on the visual and non-visual effects of light. The task analysed user requirements as well as existing technologies and design methods and documented exemplary implementations in case studies.
IEA SHC Task 59/EBC Annex 76: Deep Renovation of Historic Buildings - Towards lowest possible energy demand and CO2 emission (nZEB)
The goal of Task 59 was to document international best practice examples (knowledge base), develop a multidisciplinary planning process, and develop holistic retrofit solutions for historic buildings. As a knowledge base, the Historic Building Retrofit Atlas (www.HiBERatlas.com) emerged from the project. In the HiBERatlas more than 55 best practice examples are documented. In addition to the management of Subtask A (Knowledge Base) and Subtask C (Conservation compatible retrofit solutions & strategies), innovative technical and organizational retrofit solutions, which have already been applied in national demonstration projects and tested in practice, have been incorporated and further developed through the Austrian participation.
IEA EBC Annex 55: Reliability of Energy Efficient Building Retrofitting - Probability Assessment of Performance & Cost (RAP-RETRO)
The scope of the project is to develop and provide decision support data and tools for energy retrofitting measures. The tools will be based on probabilistic methodologies for prediction of energy use, life cycle cost and functional performance. The impact of uncertainty on the performance and costs will be considered. Methods based on probability give powerful tools that can provide us with reliable ranges for the outcome.
IEA EBC Annex 68: Indoor Air Quality Design and Control in Low Energy Residential Buildings
In this project, the scientific basis and data for a coupled calculation and evaluation of indoor air quality and energy efficiency of residential buildings were developed. Assessment metrics and detailed air pollutant models were developed and integrated into the building simulation to derive guidance for the planning and operation of energy-efficient residential buildings.
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 EBC Annex 80: Resilient Cooling for Residential and Small Non-Residential Buildings
In the project cost and energy-efficient and non-fossil solutions for cooling and ensuring summer suitability are systematically analyzed and further developed. As part of the international R&D co-operation, fragmented knowledge is bundled and made available to the Austrian construction and mechanical engineering industry. Austrian expertise in climate-sensitive building optimization is disseminated internationally through leading participation in this international research.
IEA EBC Annex 63: Implementation of Energy Strategies in Communities
As part of the "Annex 63" project, Austria has worked with 10 other countries to develop guidelines for the successful implementation of energy strategies at local level. The results include support for nine strategic measures, descriptions of case studies, support materials and recommendations for different target groups.
IEA EBC Annex 79: Occupant-Centric Building Design and Operation
The IEA EBC Annex 79 aims to provide new insights into comfort-related occupant behaviour in buildings and its impact on building energy performance as well as occupant-centric building design and operation.
IEA EBC Annex 62: Ventilative Cooling
The main goal of the Annex 62 is to make ventilative cooling an attractive and energy efficient cooling solution to avoid overheating in buildings. Ventilation is already present in buildings through mechanical and/or natural systems and it can remove excess heat gains as well as increase air velocities to widen the thermal comfort range. The results from the Annex facilitate better possibilities for both design purposes and for energy performance calculation.
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.
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 EBC Annex 82: Energy flexible buildings towards resilient low carbon energy systems
In the future, buildings and building clusters should be able to provide energy flexibility services for different types of energy systems.
