IEA EBC Annex 86: Energy Efficient Indoor Air Quality Management in Residential Buildings
Residential buildings should be able to provide good indoor air quality while ensuring high comfort and low energy use at lowest possible cost. This project will develop methods and compile data to evaluate different indoor air quality management strategies. Furthermore, innovative control strategies will be evaluated and tested in order to develop concrete recommendations for possible implementations of innovative ventilation systems for residential buildings.

IEA EBC Annex 91: Open BIM for Energy Efficient Buildings
Building Information Modeling (BIM) is considered a key technology for optimising the overall energy performance of buildings. The project lays the foundations for OpenBIM tools to include the assessment and optimisation of the energy efficiency of buildings in the future, for Open BIM processes and data models to be increasingly harmonised and standardised, and thus for smaller construction companies to have the opportunity to work on complex BIM projects in the future.
IEA EBC Annex 89: Ways to Implement Net-zero Whole Life Carbon Buildings
IEA EBC Annex 89 focuses on the pathways and actions needed by various stakeholders and decision-makers to implement whole life cycle based net-zero greenhouse gas (GHG) emissions from buildings in policy and practice. Annex 89 will support key stakeholders and decision-makers in developing and implementing effective Paris-goal compatible schemes and solutions to achieve NetZ-WLC buildings at multiple scales.
IEA EBC Annex 73: Towards Net Zero Energy Resilient Public Communities
Public buildings such as hospitals and educational institutions often house critical infrastructure that depends on sufficient energy and resource supply. The aim of the annex was to develop tools for the planning process of resilient, efficient and low-emission energy systems for such building clusters.
IEA EBC Annex 70: Building Energy Epidemiology: Analysis of Real Building Energy Use at Scale
Within the framework of the IEA-EBC Annex 70, causes of deviations between calculated and actual energy consumption in buildings were empirically investigated and requirements for data quality, characteristics and security were developed. Furthermore, recommendations were developed regarding the use of internationally uniform standards and methods for data collection, processing and evaluation.
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 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 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 75: Cost-effective Building Renovation at District Level Combining Energy Efficiency & Renewables
For the conversion of existing buildings into low(st) energy buildings with low greenhouse gas emissions, it is important to know which strategies are most cost-effective to reduce emissions and primary energy consumption of the buildings. In particular, it is important to find the right balance between energy efficiency measures and renewable energy measures. This question is addressed in this project.
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 72: Assessing life cycle related environmental impacts caused by buildings
The construction sector has great potential to reduce its energy consumption and the associated environmental impacts. The IEA EBC Annex 72 therefore focuses on the harmonization of methods for the assessment of construction-specific and operational environmental impacts (primary energy requirements, greenhouse gas emissions and other indicators) throughout the life cycle of buildings.
IEA EBC Annex 71: Building Energy Performance Assessment Based on In-situ Measurements
The requirements on building envelope and on building technology are steadily increasing. There is a lack of measurement and analysis methods to control the quality of the built implementation and to optimize the building operation. This project developed a methodological basis to enable an in-situ evaluation of the actual energy performance and building operation. For this purpose, it investigated methods to generate data-driven building models favouring the use of already available on-board data.
IEA EBC Annex 67: Energy Flexible Buildings (working period 2015 - 2019)
The project increased the knowledge on building Energy Flexibility and the regarding potential buildings can provide to energy grids. The critical aspects and possible solutions to utilize the Energy Flexibility that buildings can provide were identified and a report of the “Principles of Energy Flexible Buildings” will be published in 2019.
IEA EBC Annex 66: Definition and Simulation of Occupant Behavior in Buildings
Given the considerable implications of occupants' presence and behavior for buildings’ performance, IEA EBC Annex 66 aims to set up a standard occupant behavior definition platform, establish a quantitative simulation methodology to model occupant behavior in buildings, and understand the influence of occupant behavior on building energy use and the indoor environment.
