This project addresses the topic of demand response in buildings, focusing on the collection of case studies, technologies and collaboration models.
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 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).
