1. Design and development of a unitized modular FFG façade system and industrial production technology
In order to reach the full scale FFG module (3m x1.3m) proper manufacturing technologies had to be identified or newly developed. Within the second project period the manufacturing protocols for all part of the fluid flow glazings were developed, adjusted and expounded in detail. This includes the extrusion of profiles for frame and spacer as well as multiple steps of assembling and sealing of complete modules. Furthermore, it also includes more specific production steps, fluid chamber filling and degasifying. Due to the high complexity of the system, several revisions had to be made and more productions steps became necessary. During this project period, the first full scale fluid flow glazing module could be produced and filled successfully. The production of modules for the façade testing and the demonstrators is ongoing.
2. Modelling and measuring methodology of the physical properties of FFG elements and methodology validation
Mathematical and simulation models for fluid flow glazing were further improved during the second project period in order to enhance the usability for prediction of performance. Based on spectral, thermal, mechanical, and fluid dynamical properties, the physical behaviour of the FFG could be optimised.
3. Development of an advanced software tool for early stage detailed building planning and its integration in commercial building simulation software (e.g. IDA ICE)
The development of an FFG simulation model and its integration into IDA ICE for thermal simulation is a key objective for InDeWaG. Those models describe the change of the thermal conductivity of the glazing due to varying fluid flow rate as well as the energy gain in the FFG and make them available in IDA ICE for calculating different energy strategies for building and district heating. The integration is finished and the developed mathematical were optimised for multiple energy strategies in different climate zones. Furthermore, the proposed real size demonstrator could already be modelled successfully for the continental climate at its projected location in Sofia.
4. Exemplary building design and validation of industrial implementation at demonstrator level for different climate conditions
A real scale demonstrator with the new 3 m high FFG elements with floor surface of 7 m x 7 m in Bulgaria was designed in detail for construction. The design has been revised thoroughly several times, in order to not only maximise the output of reliable results under real condition operation, but also to meet the stipulations given by the authorities in order to achieve the permission for building. The mobile demonstrator in Spain is in operation since April 2017. The already gathered results are not only crucial for the development of the FFG but also gives valid input for construction and monitoring of the real scale demonstrator in Bulgaria.
5. Market analysis and dissemination
A wide market analysis including research on nZEB definitions and realized projects all over Europe as well as an FFG product definition and competitor analysis has been developed. The current development progress is disseminated to the scientific audience in journal articles and conferences on a regular basis. Furthermore, InDeWaG is presented to stakeholders from glass, façade and construction sector via workshops and trade fairs.
