However, the old town of cities has gradually been forgotten by people and its environment is becoming increasingly harsh. The old town usually has diversified space and function. As an important part of the old town, the street canyon that is closely related to human settlements is a public space where people communicate and do activities. Therefore, research on microclimate-based improvement of the street canyon in the old town is of great significance. Six typical street canyons in the White Stupa Temple area of Beijing were selected for research to explore spatial characteristics of the street canyon. Microclimate factors such as temperature, humidity, wind speed, and solar radiation were measured on the spot in summer. These factors were combined with two microclimate assessment indexes of physiological equivalent temperature(PET) and wet bulb globe temperature(WBGT) to evaluate the microclimate of the street canyon. In the analysis of the measured data, the mean value comparison method was used to analyze the average values of the microclimate factors in different time periods. Spatial layout of microclimate included the orientation of the canyon, the ratio of the canyon height to canyon width, and green coverage of the canyon, and an in-depth study was made on the coupling relationship between the spatial layout and the microclimate of the canyon. Research results can provide an optimization strategy for the transformation design of the street canyon in White Stupa Temple area, and provide a scientific reference for the research on spatial layout and microclimate improvement in the old town, so as to improve the living quality of residents in the old town.展开更多

This article aims to compare, through religious symbolism, structural forms and architectural spaces, two sacred monuments： The cathedral of Brasilia （1958-1967） and the stupa of the Tibetan Buddhist Center, inaugurated in 2006. The millenary construction form of the stupa, one of the primordial sacred structures for all Buddhism traditions, the sacred symbol of enlightenment, must obey some construction rules according to its lineage＇s Buddhist tradition. In this way, the stupa is the opposite of a strong and fearless structural form embodied in the cathedral, with its 16 revolution hyperboloid concrete pillars and its subterranean entrance. Although built in concrete both are unusual forms of architecture with distinct spatial conception and sculptural form structures. While respecting religious differences, it is noticeable a real commitment between form and structure, volume and religious symbolism. At the conclusion, it is perceivable how distinct forms--the Cathedral and the Stupa--can respond in analog manners to the necessity of a gathering space where visitors go in search of expressing their faith. Along with them, Buddhism and Catholicism are rooted in Brazil＇s new capital.展开更多
