Children between the ages of 6 and 14 spend much of their day in school classrooms, where they are exposed to only a fraction of the daylight quantities typical for natural outdoor conditions. This paper examines unilaterally and bilaterally illuminated classrooms in terms of quantitative and qualitative requirements for daylighting in classrooms during both winter and summer. The results of measurements and simulations pointed out the advantages of bilaterally illuminated classrooms when compared to unilaterally illuminated ones. In winter, the windows placed on two opposite walls provide a significantly higher uniformity of daylight. In summer, in addition to the improved uniformity, this window arrangement offers higher variability in shading strategies, resulting in greater availability of daylight and better visual comfort. These factors can potentially prevent or limit the development of myopia.

Therefore, energy efficiency strategies such as shading, ventilation and HVAC systems are necessary to promote thermal comfort conditions in hot climates.

The paper focuses on the design of an electric driven bicycle that can stimulate power using solar energy and the rear wheel is provided with motor. The vehicle is being designed to house one driver; essentially, there would be need for additional space for other passengers and materials In India, the pollution rate caused by fuel-consuming vehicles is very high. It is necessary to reduce the consumption of fuel/use of fuel consumption vehicle and its hazardous emissions. The sunny weather in India lasts around 9 months, hence solar powered bicycle seems to be appropriate in India. Solar powered bicycle can become an alternative to the fuel consuming bikes and scooters.

This paper analyzes the change of brake torque during normal stop and emergency braking of elevator. Taking the permanent magnet synchronous elevator traction machine as an example, the mechanical characteristics of the brake wheel and brake shoe on the brake under emergency braking are analyzed. According to the finite element analysis and calculation results, the impact and stress of the elevator are the largest at the moment of emergency braking, reaching 270.3MPa, and the strain increases gradually. The analysis results can provide reference for the design and verification of brake wheel and brake shoe of elevator traction machine.
