Practical utility of solar cookers is on rise nowadays. However, due to certain technological challenges this is not catching very fast. Present review paper encompasses studies and future possibilities for solar box cooker research. Various aspects like thermal performance parameters, various phases of designs improvements, social acceptability issues and computational methods of analysis have been discussed in relation to Solar box cookers so that technical difficulties may be minimized. This paper discusses about introduction to solar box cookers, advantages, disadvantages, various practical considerations that are key factors for any SBC. Further, there is a handsome discussion on the various computational techniques like Computational fluid dynamics, Artificial intelligence techniques, IoT etc. Introduction, review of applications till date, and future possibilities related to research using application of these computational techniques have been presented. Emphasis has been given to future possibilities for solar box cookers development so that it could be a well-accepted future technology. [ABSTRACT FROM AUTHOR]

This study numerically analyses a well-validated comprehensive work on IEQ in a naturally ventilated, occupied 3-dimensional office building with installed furniture and internal heat-generating surfaces. This study analyzes the effect of the inlet diffuser orientation (IDO) on the indoor thermal comfort (ITC) of occupants and the energy demand of the building for heating indoor air. The Optimization of ITC has also been calculated for the acceptable indoor occupant comfort and energy consumption. The study is valuable to analyze the relationship between IDO of 0 ° , 15 ° , 30 ° , 45 ° , 60°and 75 ° , on ITC and the energy consumption of the indoor environment. Different methods have been chosen to study the ITC of the occupants such as air temperature, air movement in the occupied zone, vertical temperature gradient, and PMV and PPD index according to ISO7730. The results show that under a uniform indoor air distribution, the variation in IDO considerably affects the ITC and energy consumption. Optimized ITC can reduce indoor energy consumption by 35.14%. The IDO slightly affects the PMV and PPD index. Occupant's legs are more sensitive to the naturally ventilated indoor environment due to the adverse effect of buoyancy force which may create the problem of the cold draft. For optimization of the ITC, the air temperature in the occupied zone plays a key role. • Numerical investigation of indoor environment quality and energy consumption of a modeled occupied building. • Effect of Inlet Diffuser Orientation on occupant comfort and indoor environment quality. • Assessment of PMV, PPD, temperature gradient, air temperature and velocity for indoor comfort. • Optimization of indoor thermal comfort for optimum energy consumption and thermal comfort.
