By combining the climate conditions of hot-summer and cold-winter zone, this paper has analyzed the characteristics for energy saving of windows and doors, and the approaches for energy-saving design are proposed in accordance with the functions of thermal insulation in summer, heat preservation in winter and lighting. Through the material of glass and window frame, it can provide reference to material selection for doors and windows, and various door & window energy-saving technologies are proposed, such as the structure and measures which can improve the thermal performance of window and the reasonable area ratio of window to wall.

The fossil fuel reserves in India are rapidly exhausting with the country's development. To cope with the energy crisis, end-user efficiency plays an important role. This paper deals with energy saving in lighting systems with the replacement of lighting programs, as in India there is in all sectors a growing demand for energy. A number of commonly used lighting sources and their comparison in light production were discussed. The campus lighting system consisting of a T12 fluorescent lamp for monitoring the residential and institutional area of an existing device can be replaced by proposed LED lighting with equivalent performance, but has greater efficiency to reduce light energy consumption, This improvement Endbenutzereffizienz reduce the peak and the average demand of electricity, which reduces the load on the power grid. The annual energy savings through the proposed system are about 65% over current costs, which is a significant achievement of the energy saving technology. The retrofit period for the proposed lighting system installation is a little over three years. The initial investment for a short-term rating is slightly higher, but at a long-term valuation, the initial investment for the proposed regime is reduced by 50%, as the operating time of the proposed system is approximately five times higher higher than the current regime.

Space cooling is currently the fastest-growing end-user in buildings. The global warming trend combined with increased population and economic development will lead to accelerated growth in space cooling in the future, especially in China. The hot summer and cold winter (HSCW) zone is the most densely populated and economically developed region in China, but with the worst indoor thermal environment. Relatively few studies have been conducted on the actual measurements in the optimization of insulation design under typical intermittent cooling modes in this region. This case study was conducted in Chengdu—the two residences selected were identical in design, but the south bedroom of the case study residence had interior insulation (inside insulation on all opaque interior surfaces of a space) retrofitted in the bedroom area in 2017. In August 2019, a comparative on-site measurement was done to investigate the effect of the retrofit work under three typical intermittent cooling patterns in the real-life scenario. The experimental result shows that interior insulation provides a significant improvement in energy-saving and the indoor thermal environment. The average energy savings in daily cooling energy consumption of the south bedroom is 42.09%, with the maximum reaching 48.91%. In the bedroom with interior insulation retrofit, the indoor temperature is closer to the set temperature and the vertical temperature difference is smaller during the cooling period; when the air conditioner is off, the room remains a comfortable temperature for a slightly longer time.
