Der Einsatz von nachhaltigen Gebäudeelementen (z.B. Fassadensysteme, Speichermassen) und deren schlüssige Einbindung in integralen Gebäudekonzepten stellt eine viel versprechende Möglichkeit dar, CO2-Emissionen beim Betrieb eines Gebäudes deutlich zu reduzieren. Diese Elemente reagieren dabei auf äußere (Klima) und innere Einflüsse (Nutzerverhalten, interne Lasten), um ein behagliches Raumklima bei minimalem Energieeinsatz für Heizen, Kühlen, Lüften und Belichten zu erlangen. Wesentliches Ziel innerhalb dieses Projektes war es, Verbesserungen bei Auslegung, Betrieb sowie Effizienz der Komponenten und Systeme integraler Energieversorgungs- und Gebäudekonzepte zu erzielen.

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 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 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

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.
