The methodology for establishing the evaluation system for residential environment was first analyzed; then the subjective evaluation data-base was established by questionnaire survey; and at the same time, the objective evaluation data-base was constructed by Geographic Information System (GIS); and then the related equation system between subjective and objective system was developed by multiple regression analysis. This research could benefit evaluation of the residential environment quality for various purposes, and also provide important rudimentary data-base for the development and improvement of residential environment for officials. Furthermore, the index system and evaluation model established in this research could construct a strong relation between subjective evaluation and objective data; and thus could provide a comprehensive, efficient and effective methodology for the evaluation of residential environment.展开更多

The suitable evaluation index system was established, and the regional residential environment characteristics and personal residential preference types were analyzed, so that their influence on residential environment evaluation could be grasped. The results can be applied to the residential environment planning, construction and monitoring of local cities.展开更多

As a case study, ULCA was applied in the environmental impact assessment of the land readjustment project of Hyogo District of Saga, Japan. In addition, mitigation proposals for reducing CO2 were also presented and the relevant environmental ef-fects were simulated.展开更多

The features of this kind of tool have been illustrated. The reliability, user friendliness, and usability are the most important characteristic of the early design software. This paper introduces an integrated energy design tool - LT Europe, which is widely used in the UK architectural practice and European. The climate data for Beijing has been produced from Meteonorm and integrated into LT Europe. A case study has been performed and the comparisons have been made by applying the Chinese old and new building energy regulations. It has been demonstrated that LT Europe software can be used for Chinese building energy design at the early stage by creating the local proper climate data.展开更多

Albedo, from the thermal point of view, is the prime parameter of interest; however, it does appear to be too conceptual in practice. Architects, when considering choices of envelope colour, the actual decision is between various colours: yellow, blue, or green rather than a single numerical albedo. This study is to investigate the effect and magnitude of colour, in terms of visual qualities hue, value (lightness), and chroma (saturation), on thermal load of buildings. In the experiment, air temperatures inside test cells painted into different colours were measured, the results suggest that colour attribute: chroma has negligible effect on thermal performance of building envelope, while value has significant thermal effect. The effect of hue, as shown in this study, was insignificant, however further study might be needed as to obtain a clearer picture of its effect.展开更多

It draws on recent research of monitoring, surveying and modelling urban thermal characteristics and proposes a method of mapping urban diversity. Because the urban context provides a rich and varied environment that influences the way we use urban spaces (movement, sequence, activity) and how we feel in them (stimulation, thermal comfort), the aim here is to highlight the notion of diversity. Thus thermal diversity is used as a measure of the urban environment, rather than more conventional spatially or temporally fixed average values.展开更多

The results of energy efficient residential building design for the different climate zones of China by implementing an integrated energy model have been presented. Optimum measures of building design for typical Chinese residential buildings are introduced, with the objective of minimizingannual energy consumption for those buildings and improving thermal comfort. One overriding conclusion is that significant energy savings and thermal comfort can be achieved though optimum design.展开更多
