abor. The population movement between regions provides a guarantee for the sustainable development of the city. Therefore, the interactive relationship between urban development and population mobility needs more in-depth research. This research combines official statistics and emerging big data to study the interactive relationship between urban development and population mobility from the macro, meso and micro levels. In addition, with the help of exploratory spatial data analysis methods, the spatial effects between urban development and population mobility can be captured, including spatial dependence and spatial heterogeneity. The use of spatial econometric models reveals the driving forces that affect population mobility. The results of the empirical analysis can provide a theoretical reference for the future development of China’s urbanization.

概要:
The indoor thermal environment in the hot summer and cold winter (HSCW) region is the worst in China. Residences in this region are mainly outside-insulated and perform poorly under the intermittent cooling/heating modes in individual
…
rooms. Interior insulation is proposed to be a more suitable way under such usage patterns. Bedrooms of a high-rise residential unit in Chengdu, a typical city in the HSCW region, were retrofitted with interior insulation. Comparative field experiments were performed during the cooling and heating seasons, and the main conclusion can be summarized as follows. Firstly, the retrofitted south bedroom had a good energy-saving effect both in summer and winter. Secondly, the indoor temperature was better controlled in the retrofitted south bedroom, closer to the setpoint. And temperature difference was smaller both horizontally and vertically. Thirdly, the retrofitted south bedroom outperformed the north one in terms of both energy-saving rate and indoor thermal environment.
