Abstract: This paper draws upon passive cooling and passive solar techniques to integrate them into a common multi-purpose building in South China so as to optimize the indoor thermal environment and reduce building energy consumption. Meanwhile, it also discusses how to combine architecture design and sustainable techniques reasonably. In order to prove that these sustainable design options are effective, CFD, Ecotect and Solpass software should be used to simulate or calculate the heating and cooling loads, discomfort hours for both of the existing and advanced building. Though comparison it is obviously that the indoor discomfort hours decrease by nearly one third by passive cooling system, while passive solar techniques can reduce 25% annual heating loads.

Abstract: Taking the spatial pattern and the environmental elements as the starting point for the study of the ecological design of high-rise office buildings, this paper brings forward the concept of Eco-space Complex, structuring an open and dynamic spatial function complex as well as an eco-conditioning system..

Abstract: Activity support is one of eight elements which Hamid Shirvani has generalized. It is also the element which is the most direct with the relationship of people’s activities and the most difficult with operation and description in the eight elements. While Extenics is that we use the formal model to study the possibilities of expansion and the rules and methods of innovation. Extenics can make use of basic-element model to describe everything. So we can do formal analysis on the objects of study, such as activity support element. Based on activity support element, the article is using the concepts of matter-element, affair-element and relation-element in Extenics to analyze activity support element, and using the principle of divergence analysis to do expansion analysis, which can make the activity support element systematically integrate the other urban design elements among the correlative net. There is the methodological significance with scientifically processing the relationship of behavior and environment in the article.

Abstract: Due to the advance of computer science, we now have more powerful tools to digitize and analyze the complex system of urban form, which was difficult for describing and exploring previously. Space syntax theory and method is one of these tools which can help to clarify the social logic of space quantitatively. By this tool, this study examined the urban transformation process of the London area of Soho in the last 100 years, aiming at articulating the intriguing form and function relationship. This study proposed that although the spatial change and social change are in different speed, their changing process still intertwined and interacted with each other.

Abstract: Louver is usually used as a sun-shading member in buildings. Nevertheless, the usage of traditional louver sun-breaker is merely limited to its sun-shading function. In present study, a new deflector louver sun-breaker composed with multi-functions of sun-shading, heat-insulation, rainproof and ventilate in summer, thermal insulation and windproof in winter, direct light shading in sunny day and light guiding in cloudy day is developed. The new navigate pressure deflector louver sun-breaker with simple construction and economy durability can improve the energy efficiency of building, increase the comfort of internal environment and beautify the appearance of building facade.

Abstract: In order to deal with the problem of flood disaster, water balance system damage and eco-environment deterioration for cities with development of urbanization in rain and snow area, an urban road cross section eco-design program with storage-infiltration utilization of rainwater and snowfall was proposed with the purpose of groundwater eco-replenishment, water conservation and snowfall stack, also ecological cross section form that can be used in practical engineering and enhancement of infiltration capability for sunken green space of urban road were put forward, and some effective anti-infiltration measures for subgrade and pavement were proposed to prevent the adverse action on urban road from the water in the sunken green space. The eco-design program increases storage-infiltration of rainwater and snowfall with holding the function of traffic organization, drainage and road landscape that belongs to the traditional urban road cross section, and it changed a single drainage system into a compositive storage-infiltration-drainage system. The eco-design program provided a basis and reference for urban road cross section eco-design in rain and snow area.

Abstract: In the field of intelligent building, managing energy consumption effectively in various types of construction equipment, improving energy efficiency, has been seen as an important and difficult subject. This thesis through establish building energy management system; realize building energy management by unified management of construction equipment.

Abstract: Water network play an important role in the natural and human environment, green network is basis for achieving ecology; town is main focus of environment which is hot research issue. Systematic layout of the water network, green and urban space is core contents for ecology planning in water networks. The article research ecology through water networks and green, therefore, distribution problem such as water, green land and construction land could be solved properly; we can achieve comprehensive development on the premise of ecological function, thus, human and natural's networks and ecological combination can be achieved at the same time.

Abstract: Based on the climate of Chongqing area, this study simulated and analyzed different simplified building external shading methods via energy simulation software, defining 30˚ as an interval, and finally obtained the optimized strategies for building external shading methods in 12 orientations, providing the simple and explicit shading choices for architects during the plan design.

Abstract: Glass is remarkable material and its functionality is significantly enhanced when it is processed or altered to provide added intrinsic capabilities. The overall performance of glass elements in a building can be further enhanced when they are designed to be part of a complete façade system. Finally, the façade system delivers greater performance to both the owner and the occupants of the building. A limited number of facade technologies or combinations of technologies can be evaluated in a field test program, for the reason of both resource constraint and the practical use. The specific method can be used to determine what technologies are to be selected for the research. It based on technical and market objectives, surveys of commercially-available technologies, manufacturers, architects and engineers, utilities, and other stakeholders.
