A tool Smart Glazing Simulator (SGLSim), has been developed to perform parametric simulation analysis of different window systems with several window-to-wall ratios and orientations to compute and compare the annual energy performance. The net annual energy performance of the building is based on the electricity consumption in heating, cooling, interior lighting, and appliances, along with the electricity generation by the photovoltaic (PV) glazing, which is used to evaluate the energy performance of smart glazing. Performing parametric energy simulations and calculating the net annual electricity consumption of different combinations requires building modeling and energy simulation expertise. A web-based parametric tool can assist the user in carrying out the desired studies without requiring extensive technical knowledge. A case study is prepared for India's warm and humid climatic zone. This study examines the benefits of double pane semi-transparent photovoltaics (STPV) glazing, STPV glazing with dynamic internal blind, and electrochromic (EC) glazing over other traditional glazing systems. The study shows that the optimal net annual electricity consumption in the case of STPV windows is 10–12% less than the optimal value obtained in a simple glazing case. Additionally, the result suggested that glare-controlled interior blinds in the STPV window further reduce the net annual electricity consumption by up to 15% compared to conventional glazing. Similarly, installing the EC glazing reduces the yearly electricity consumption by up to 5% compared to standard glazing. [ABSTRACT FROM AUTHOR]

Glazed tiles were employed by the Mughals for the decoration of their monuments in northern India over the sixteenth and seventeenth century. The character and composition of thirty tile samples from Mughal buildings at Delhi, in northern India, were investigated by EPMA-WDS and SEM-EDS. Analysis shows that the tiles have stonepaste bodies, indicating that they form part of the family of Islamic ceramics. The glaze layers are determined to have local characteristics, through comparisons with traditional Indian glass compositions. A local source for the cobalt oxide used to colour dark blue coloured glazes has been suggested. Overall, the study considers the impact of an imported luxury/high status technology on local traditions, and how the two converge to develop a new chaîne opératoire which has aspects of Islamic and indigenous technologies.

Coloured tiles from two northern Indian monuments were analysed for their body and glaze composition. The results suggest that three different groups of tiles were used, all comprising a stonepaste body with alkali glaze. One group has strong similarities to a major Indian glass group, known as high alumina mineral natron glass, while the other two are similar to Western and Central Asian plant ash glazes, although with much lower lime content. The colorants conform with those usually employed in pre-modern glazes, with lead-tin yellow Type I and Type II for opaque yellow, copper blue-turquoise, cobalt blue, manganese purple, and green through mixing of lead-tin yellow and copper blue [ABSTRACT FROM AUTHOR]
