Passive Solar Architecturearpita patelPassive solar architecture utilizes building materials, design, and orientation to collect, store, and distribute solar energy for heating and cooling without mechanical or electrical devices. It involves designing windows, walls, and floors to maximize solar gain in winter and minimize it in summer. Techniques include direct gain, indirect gain through thermal mass walls or roof ponds, and isolated gain. The goal is to provide thermal comfort year-round while reducing energy costs. Passive solar cooling also employs natural ventilation strategies like operable windows, wing walls, and thermal chimneys to draw in breezes without mechanical assistance.
Thermal Insulation System for energy efficient buildingsASHRAE Rajasthan ChapterThermal insulation provides several key benefits for buildings located in tropical countries. It creates an insulated envelope that stops heat and cold from transferring into or out of the building. This maintains interior temperatures for longer periods and improves human comfort while reducing energy costs. The document discusses the necessity of insulation, design considerations, common application methods, and case studies. It also covers the Energy Conservation Building Code which determines minimum insulation thickness requirements. External insulation on roofs and walls is most effective at stopping heat at its source, while internal insulation provides faster cooling for individual rooms.

Solar chimneySuchit GuptaThe document analyzes the performance of a solar chimney through experimental testing and theoretical modeling. It describes the working principle, types, advantages and applications of solar chimneys. Experimental results show mean air temperature, wall temperature, and glass temperature increase with increasing solar radiation and air gap depth. Air flow velocity and efficiency also increase under higher solar radiation levels. Theoretical predictions generally agree with experimental measurements, particularly for larger air gap depths. In conclusion, reverse air flow was not observed for gap depths up to 0.3m and experimental/theoretical results showed satisfactory agreement for large gaps.
Light Beyond Visionswissnex San FranciscoThis document summarizes a presentation on daylighting in buildings and its effects on human circadian rhythms and health. It discusses various daylighting design tools and technologies, including anidolic daylighting systems that can provide significant increases in daylight provision. Experimental findings show that daylight exposure in an office with anidolic systems can provide higher circadian efficacy than artificial light, due to daylight's spectral composition and dynamics. Optimizing light quality and exposure for circadian functions may require considering aspects of building science, physiology, and individual human factors. Further research is needed to better understand light's short and long-term impacts on human health and performance.
