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

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
