Ventilated windows have the potential to contribute both indoor air quality and energy efficiency in cold climates. A typical ventilated window functions as a solar collector under inward flow direction incident radiation. The is modification of multiple pane which drawn from outside heated through conduction, convection, radiation cavity. In this study, detailed parametric analysis was conduct...

outdoor experiments on a once-through single glazed solar air heater with perforated metal absorber plate were conducted to determine the practical effect of absorber plate porosity as well as suction air flow rate on the collector thermal efficiency and its total pressure drop. three aluminum absorber plates were made perforated by drilling circular holes with different diameter/pitch ratios i...

OBJECTIVE To investigate the two-body wear performance of monolithic dental ceramics with different surface treatments. METHOD AND MATERIALS Standardized specimens (n = 8/ series) were fabricated from three monolithic dental ceramics (experimental translucent zirconia, experimental shaded zirconia, lithium disilicate). Four groups of each material were defined according to clinically relevant...

The objective of this paper is to assess the capability of existing lighting simulation methods to predict the performance of complex fenestration systems (CFS), whose potential in daylight and sunlight control make them an increasingly popular alternative to conventional glazing. The research was conducted in two phases. First, collect reliable reference data by taking illuminance measurements...

Solar cookers are aimed at reducing pollution and desertification in the developing world. However, they are often disregarded as they do not give users the ability to cook after daylight hours. The Wilson solar cooker is a solar cooker designed to address this problem by converting solar energy and storing that energy as heat in the form of molten salt (lithium nitrate). This thesis involved r...

traditional building technologies have much to teach us about how to design regionally appropriate structures. the orosi is one of these useful technologies, which has been used for many centuries in order to control the harsh sunlight in iran. this architectural element was rather important because the intensive solar radiation could easily damage valuable carpets used in most spaces in persia...

The energy efficiency of the urban texture relies notably on the buildings’ form, which characterizes its capability to take profit of the solar potential as well as its loss of energy through the envelope. Therefore, the general layout at the district scale has a significant impact on the global energy balance in a dense built environment, where the relative position of the adjacent buildings ...
