The "International Scientific Conference on Contemporary Glass Facades - Zagreb 2023" was organized as part of the project Development of a double facade with hermetically sealed cavity (H-CCF), which implements private company KFK d.o.o. in cooperation with the Faculty of Architecture University of Zagreb as a scientific partner.
On the world market, there have been single- and double (ventilated) skin facades, and only recently double skin facades with hermetically sealed cavities were introduced. To apply strengths of both single and double (ventilated) skin facades – lower maintenance costs, larger depth to the outside, wind-protected sun blinds, reduced need to heat the inside of the building, lower cooling needs, no condensation risks, etc. — a new type of closed cavity facades (CCF) was researched. The project was based on the idea from the observed market trends and inquiries from current and potential customers to make the current type of CCF independent of additional units (compressors, filters, air dryers, etc.). Existing facades with a closed cavity prevent condensation on the inner surfaces of the glass (in a closed cavity) by supplying prepared dry and purified air, requiring active maintenance and service. This scientific research showed that the idea of an H-CCF facade with passive maintenance of dry air inside a closed cavity has its likely practical application and development potential.
For this reason, an experimental polygon at the location of the private company KFK d.o.o. in Rugvica was created. Polygon was equipped with necessary tracking devices for monitoring all relevant parameters (temperature and relative air humidity, solar radiation, air pressure, wind speed, and direction), and all other parameters within the experimental samples of the façade elements (temperature of the glass layers, air gap relative humidity, glass deflections). Research members from the Faculty of Architecture, University of Zagreb were engaged to create a theoretical and computational model for the calculation of the dynamic behavior of this type of facade in different climatic conditions. Physical processes in CCF monitored in both physical and computational models in this project were solar irradiance absorption, heat transfer, pressure equalization, moisture control, dry air supply, and deflection. Eventually, a software was created for programming CCF façade elements on future architectural projects.
The main specificity of the development of the H-CCF facade consists of the fact that the cavity is hermetically sealed, and the only connection with the external environment is through a capillary that serves to equalize the pressure. In addition, the capillary-desiccant system implemented in this way eliminates the need for active systems for blowing in dried air or changing the saturated desiccant, which eliminates the total energy consumption of using and maintaining these systems. Passive moisture control with a desiccant inside the cavity led to the results of desiccant capacity, and by that to the whole facade element efficiency, to last for an average of 25 years.
This Conference was organized to present the development of the H-CCF facade and glass facades in general, primarily to exchange research experiences in this area and connect researchers from Europe. This is the first Conference in Croatia organized by the Faculty of Architecture University of Zagreb on the topic of glass facades, and we expect further development of this theme in the future.
