后现代规划设计理念在历史街区更新保护中的应用

后现代理论认为城市充满复杂性、多样性和不确定性,应重视对历史文脉的延续和人的多种需求,主张用动态、高兼容性、可持续发展和延续文脉的方法去解决城市问题和规划城市.基于后现代规划设计理念,在历史街区更新保护中可借鉴"嫁接更新理念",重视对历史建筑的"改造再利用",实施"弹性发展单元""刚性 柔性"的功能控制,协调社会多元主体的利益.

盛世天街--北京前门大街环境规划设计

前门大街环境规划设计从尊重历史文脉出发,结合时代的发展,提出了＂盛世天街＂的设计主题.规划设计与前门的历史发展、建筑商业业态和两侧街巷的功能相结合,设计了4个主要景观节点,并以街中街的形式划分横向空间.通过对建筑风貌的控制、地下空间的利用、绿化设计、交通组织,前门大街将成为一条融历史与时代于一体的步行街.     

Urban environment influence on natural ventilation potential

Natural ventilation is less effective in urban than in rural environment, especially in street canyons. Reduced wind velocity, urban heat island, noise and pollution, are considered to be important barriers to its application in urban environment. To quantify their effect on ventilation, wind, temperature, noise attenuation and outdoor–indoor pollution transfer were measured for a large variation range and for various types of urban configuration. The models obtained can be used in the initial stages of building design in order to assess the viability of natural ventilation in urban environment, especially in street canyons.     

Wind tunnel simulation studies on dispersion at urban street canyons and intersections—a review

Increased traffic emissions and reduced natural ventilation cause build up of high pollution levels in urban street canyons/intersections. Natural ventilation in urban streets canyons/intersections is restricted because the bulk of flow does not enter inside and pollutants are trapped in the lower region. Wind vortices, low-pressure zones and channeling effects may cause build up of pollutants under adverse meteorological conditions within urban street canyons. The review provides a comprehensive literature on wind tunnel simulation studies in urban street canyons/intersections including the effects of building configurations, canyon geometries, traffic induced turbulence and variable approaching wind directions on flow fields and exhaust dispersion.

Application of the space syntax theory to quantitative street lighting design

A new design methodology for quantitative street lighting design planning using space syntax theory, which is used to generate a strategic design framework based on detailed analysis of spatial configuration, is described. The space syntax theory is based on the fact that any urban area can be represented as a matrix of connected spaces, and that mathematical properties of this matrix can be measured using computer simulations. This study explores the development of a strategic street lighting design methodology based on the results of the space syntax model, especially a level of pedestrian movement, which may have widespread usefulness in a schematic urban lighting design stage. As a case study, the relationship between observed pedestrian movement rate and the measured illuminance values of a particular district in Seoul, Korea is analyzed, and then a new quantitative street lighting plan is proposed.
