Especially for new-generation buildings, since esthetic appearance as well as thermal comfort is essential, glass materials have been widely used as building materials in buildings. Due to its superior optical properties, it is preferred in buildings, especially in window areas. On the other hand, the heat losses and gains and light transmission rates from the glass used in the building envelopes and especially in the window areas are very effective on the energy efficiency of the buildings. Therefore, innovative glass technologies are developed and used in new smart buildings. In this context, the most preferred glass technologies are laminated glass and tempered glass for the building envelope. For window areas, it can be listed as low emissivity glasses, high-technology glasses, vacuum glasses, glasses with phase change materials and insulated glasses.The use of new-generation glass technologies instead of traditional glass technologies provides significant benefits to users regarding economic, environmental, and social effects.

Cuce, Erdem; Cuce, Pinar Mert; Riffat, Saffa
Buildings play a key role in total world energy consumption as a consequence of poor thermal insulation characteristics of facade materials. Among the elements of a typical building envelope, windows are responsible for the greatest energy loss because of their notably high overall heat transfer coefficients. About 60% of heat loss through the building fabric can be attributed to the glazed areas. In this respect, novel cost-effective glazing technologies are needed to mitigate energy consumption, and thus to achieve the latest targets toward low/zero carbon buildings. Therefore in this study, three unique glazing products called vacuum tube window, heat insulation solar glass and solar pond window which have recently been developed at the University of Nottingham are introduced, and thermal performance analysis of each glazing technology is done through a comparative experimental investigation for the first time in literature. Standardized co-heating test methodology is performed, and overall heat transfer coefficient (U-value) is determined for each glazing product following the tests carried out in a calibrated environmental chamber. The research essentially aims at developing cost-effective solutions to mitigate energy consumption because of windows. The results indicate that each glazing technology provides very promising U-values which are incomparable with conventional commercial glazing products. Among the samples tested, the lowest U-value is obtained from the vacuum tube window by 0.40W/m2K, which corresponds to five times better thermal insulation ability compared to standard air filled double glazed windows.
