A large number of residential buildings in hot summer and cold winter zone of China are non-energy efficient with poor indoor thermal conditions. Retrofitting residential buildings with energy efficiency measures is thus important for residents. However, this work progressed slowly because practically applicable measures that not only have high energy savings but also improve indoor thermal performance have not been studied. Thus, this paper carried out a simulation study on the selection of suitable energy saving measures for residential buildings in hot summer and cold winter zone of China. Five potential energy saving options are considered and the energy, indoor thermal comfort and economic performance are compared. The results show that adding movable solar shades is the optimum option with all performance indices ranking first. Meanwhile, this measure is also the only acceptable energy saving solution for residents since its payback period is less than the lifespan of a building. As a conclusion, it is recommended to use movable solar shades as a first priority when retrofitting residential buildings.

In the cold regions of northern China, compared to the urban residential buildings, the rural residential buildings are lack of energy-saving technology, which currently in its infancy, some places even still blank, this does not meet China's energy conservation policy, is not conducive to the sustainable development of the country. For this reason, this paper is focused on rural residential building, starting from environmental analysis and technical measures, analyzed on rural residential energy-saving design, and also make research and discussion in terms of building sitting and planning, shape and layout of the building, building structure and technology.

Building energy conservation is a research hotspot at present. In this paper, using energy simulation software DesignBuilder, we analyzed the influence of different external window materials on energy consumption of residential buildings and finally studied the energy saving rate and economical efficiency. The economical efficiency was analyzed from two aspects: the difference of net present value and the pay back period. The result shows that Low-e insulating glazing is good at both energy-saving potential and economic benefits. This paper provides a basis for the external window selection in hot summer and cold winter areas like Wuhan.
