Integrated energy design – Education and training in cross-disciplinary teams implementing energy performance of buildings directive (EPBD)
In Europe, energy and climate policies started to take shape from the 1990s onwards culminating with the ambitious 20–20–20 climate goals and the Low-Carbon Europe roadmap 2050. The European Commission empower the importance of achieving the objective of the recast Directive on energy performance of buildings (EPBD) that new buildings built from 2021 onwards will have to be nearly zero-energy buildings. The general belief is that the energy performance optimization of buildings requires an integrated design approach and cross-disciplinary teamwork to optimize the building's energy use and quality of indoor environment while satisfying the occupants' needs. In this context, there is a substantial need for professionals such as architects and engineers specifically trained and educated in integrated design approach and trained to work in cross-disciplinary teams. To be able to push forward the development, it is essential that educational institutions foster professionals with such knowledge, skills and competences. An initiative toward this direction is the EU-project of IDES-EDU: “Master and Post-Graduate education and training in multi-disciplinary teams”. The paper describes the necessity of more integrated and cross-disciplinary approaches to building design through state-of-the-art of the building sector and educational initiatives in the participating countries in the project, and through theory of design processes. The paper also communicates the results of newly developed cross-disciplinary education established by fifteen different educational institutions in Europe. Finally, the paper explains and discusses the challenges encountered during development and implementation of the education across different professions and countries.

Development of a Hardware-in-the-Loop Test Method for Heat Pumps and Chillers
The work presents the development of a Hardware-in-the-Loop test method which enables the solving of integrated energy design problems at a system and concept level for the heat and cold supply of NZEBs based on electrically and thermally driven heat pumps and chillers. The main result is the realization of a test rig consisting of hardware (e.g. thermally driven chiller, or heat pump etc.), of software (e.g. LabView, TRNSYS) and the interface for the interaction of hardware and software.
