Abstract: Today there is increasing interest and demand for energy savings in the building sector. Windows still represent a weak point in the building envelope with respect to thermal performance due to thermal losses from the interior to the exterior as well as overheating of the interior due to excessive solar radiation from the exterior environment into the interior. However, windows and glazing structures enable the utilisation of daylight and heat from incident solar radiation, while at the same time providing comfort and a view to the outdoor surroundings. Multipane glazing and windows may represent a possible way to lower energy consumption related to heating and cooling. In this study, a multipane glazing structure, more specifically a 6-pane glazing, has been constructed and investigated with regard to various properties and possibilities. The general configuration of the 6-pane glazing is described. Furthermore, properties such as U-value, solar energy transmittance, visible transmittance, solar heat gain coefficient, glass pane temperatures, vapour permeability, economical aspects, and comfort of living, among others, are analysed. Finally, a case study is presented that demonstrates a 50% reduction in the annual energy consumption after renovation with this 6-pane glazing.

Abstract: Cold mineral and thermal waters from Tertiary aquifers in the Mura Basin mainly belong to the Ca-(Mg)-(Na)-HCO3 and Na-HCO3 hydrogeochemical facies, respectively, and the concentrations of yttrium (Y) and lanthanides or rare earth elements (REEs) are far below (10-2 – 10-4) the abundances in the aquifer sediments. Mineral waters are high pCO2, and the plots of concentrations of YREEs normalised to Post Archean Australian Shale (PAAS) show fractionation of Y and heavy REEs (HREEs) over light REEs (LREEs), and a significant positive europium (Eu) anomaly. Thermal water from regionally developed aquifer Thermal I (recently also termed the Mura/Ujfalu Formation aquifer) shows a similar PAAS-normalised pattern with an obvious positive Eu anomaly and the tendency of enrichment with middle REEs (MREEs). The plots of PAAS-normalised YREE concentrations in thermal waters from the underlying low-permeability aquifers with poorly developed fracture porosity and abundant CO2 are flat with insignificant positive Eu anomaly. The abundance and fractionation of YREEs in mineral and thermal waters seems to be mainly controlled by the presence of carbonate complexing ligands, permeability of the aquifers and the related time of water-rock interaction.
