Climate Neutral Buildings and Cities
Building physics evaluation of green façades and roofs. Development of standardized measurement methods and characteristic data acquisition for the consideration of green roofs in the energetic design of buildings.
The CAE has been researching green roof systems in conjunction with innovative façade technology for some time. This has now resulted in the U-green project. In it, commercially available façade and roof greening systems are first classified and then characterized in terms of building physics and thermal performance. This will make it possible to reliably determine the thermal insulation effect and evaporation performance of greening components and systems.

Development of a hybrid solar collector for photoisomeric and thermal energy storage. In the EU-funded MOST project, an overall system is being developed in which solar energy that is volatile due to photoisomerism can be stored long-term and without losses so that it can subsequently be used for heating buildings. The overall system consists of a hybrid collector, storage units, heat generation module and consumer (e.g. building). CAE has the task of developing a special hybrid collector for the requirements of the project, which deviate significantly from the requirements placed on commercially available collectors, from a functional model on a laboratory scale to practice in several stages.
This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 951801

Development and monitoring of an overall system for the combined regenerative supply of buildings with heating, cooling, electricity and fresh air.
The project goal is an innovative overall concept for the combined regenerative supply of buildings with heating, cooling, electricity and fresh air. The focus is on the most comprehensive and efficient use of available regenerative environmental energy and the linking with LowEx systems for building cooling, heating and ventilation. The core of the system is a PVT collector that simultaneously generates electricity, heat and cooling from purely renewable sources.

Development of a compact ultra-slim highly integrative PV warm façade element in passive house standard with high performance thermal insulation and latent heat storage.
The BIPVslim project aims to develop an ultra-slim, passively cooled BIPV warm façade with a heat transfer coefficient below 0.15 W/(m2K) (passive house standard) with a high degree of prefabrication for installation in mullion-transom structures. This compact solar-active façade element can be implemented as a finished composite system of components or as a plug-in box system on façades of existing buildings as well as new buildings for individual adaptation to different climate zones and application scenarios.
