Due to the climate change debate, a lot of research and maps of external climate parameters are available. However, maps of indoor climate performance parameters are still lacking. This paper presents a methodology for obtaining maps of performances of similar buildings that are virtually spread over whole Europe. The produced maps are useful for analyzing regional climate influence on building performance indicators such as energy use and indoor climate. This is shown using the Bestest building as a reference benchmark. An important application of the mapping tool is the visualization of potential building measures over the EU. Also the performances of single building components can be simulated and mapped. It is concluded that the presented method is efficient as it takes less than 15 min to simulate and produce the maps on a 2.6 GHz/4 GB computer. Moreover, the approach is applicable for any type of building.

A field survey on energy consumption by hot water supply and cooking was conducted in two cities in China, Nanjing, and Hefei. In each city, 5 housing complexes were selected, and approximately 100 or 200 residential units were selected from each of them. The following items were surveyed: (1) fundamental information, such as number of family members, data on residents, etc., (2) bathing style, and (3) frequency of cooking and cooking time. Most of the residents take showers seven times a week in the summer, but less frequently in the winter. In contrast, the frequency of taking baths increases to several times a week during the winter, compared with 0 or 1 times a week in the summer. These results differ slightly depending on the heating and cooling systems used in the houses. The frequency with which people cook in their own houses ranges from 4 to 7 times a week, which means that “eating out” is relatively frequent, although the result differs significantly among the housing complexes. Distribution of the cooking time has usually two peaks at 20 to 30 min and 50 to 60 min (or 30 to 40 min and longer than 60 min) for lunch and dinner, respectively. The high energy consumption for cooking might be due to the long cooking time.

The presented work addresses the topic of energy savings in existing public buildings, when nosignificant retrofits on building envelope or plants can be done and savings can be achieved bydesigning intelligent ICT-based service to monitor and control environmental conditions, energy loads and plants operation. At the end of 2010 the European Commission, within the Seventh Framework Program, has founded a project entitled “Smart Energy Efficient Middleware for Public Spaces” (SEEMPubS). To achieve this goal the project will implement, in a set of demonstrator buildings, an interoperable web-based software and hardware solution for real-time monitoring and control of lighting, heating, ventilation and air conditioning services, through both wired and wireless sensor networks. In this paper the first phase of the project, concerning the selection of the environments to be used as demonstrator and the definition of the control and monitoring strategies to reduce energy consumptions for lighting and air conditioning, are presented.

The development of sustainability has made the application of green concepts to cityscapes and urban design mandatory and has popularized the installation of vegetation on external street walls. Introducing greenery on external building elements is beneficial to the environment, reducing the heat impact experienced in “urban heat islands” and enhancing an area's visual effect. The popularity of such green systems has necessitated the assessment of their acoustic characteristics and their impact on long-distance noise propagation. These effects become important in hot climates, where the topology of the dense urban texture gives building walls larger areas than exposed streets, thereby amplifying the effects of the former's acoustic characteristics on noise levels. Considering the resultant sound level at a particular location between buildings as the contribution of several remote sources, a simplified computer model based on energy exchange is developed in this study. Owing to the complexity of the urban landscape, buildings are assumed to be an array of rectangular blocks. The computer model is used to investigate the effects of the installation of street vertical vegetation on long-distance noise propagation, as well as those of the geometric parameters of the dense Islamic urban texture on the resultant noise levels.

This study assessed the performance of residential buildings in public housing estates in urban areas of Ogun State Southwest Nigeria. It was based on the notion that users’ satisfaction with dwelling units is a measure of the performance of residential buildings in meeting their needs and expectations. A cross sectional survey of 452 household heads in nine public housing estates was conducted in the study area. Data were obtained using structured questionnaire and observation schedule; and were subjected to descriptive statistics and factor analysis. A mean satisfaction score of 3.21 was observed; indicating that the respondents were generally satisfied with the performance of the different components of the buildings. Satisfaction levels were generally higher with privacy and sizes of living and sleeping areas than the availability of water and electricity in the buildings. The type, location and aesthetic appearance as well as size of main activity areas were the most predominant factors that determined satisfaction and indeed the performance of the buildings in meeting users’ needs and expectations. The paper highlights critical areas where attention is needed in order to improve the performance of residential buildings and users’ satisfaction with public housing projects in Nigeria.

The research of modern Chinese architectural history formally started in the mid-1980s and the first conference held in 1986 in Beijing marks the establishment of the field. Over the past 26 years, this emerging field has developed fast and steadily. As a result, thirteen biennial conferences have been held since 1986, and academic products of various forms with over ten million characters have been published. This article surveys the development of modern Chinese architectural history as a field of scholarly inquiry in China and outlines some of keystone events in the past 26 years. It also charts out how some key concepts of the field, such as timeline, geography and research approaches have been evolving over time. The article introduces some of the most significant studies in modern Chinese architectural history from the middle 1980s to the present.

The ancient walls of Diyarbakir are the city's most important urban element, exhibiting an artistic grace through the arrangement of the towers, architectural values, dimensions, materials, and decorations. Diyarbakir is located at the crossroads of important trade routes, one connecting the Western World to the Far East and the other connecting North to South. Architecturally, its defensive walls and towers make it one of the most important surviving castles. In this study, the history, location, architectural and building properties of fortifications of Diyarbakir were explained and technical dimensioning typology studies on towers and city walls were submitted.

China's large public buildings (LPBs) often become problematic after only a few years' operation, leading to shortened building lifespans. Lacking architectural programming was identified by the industry regulators as a contributing factor to this. Despite a policy shift on the government side since 2007, little evaluation of the actual situation has been made. To raise awareness and attention to this pressing issue from the building industry, its regulators and the general public, a questionnaire survey focusing on the top-tier sector of professional practice in programming LPBs was carried out in Shanghai, China in 2009. The objectives were to evaluate current trends and pressing issues, identify major challenges and opportunities, and make recommendations for improvement. This paper presents a six-part analysis of the survey's findings from 57 professionals and clients who shared their hands-on experience on various programming issues and provided first-hand data of 90 LPBs developed in the 2000s. This pioneering study revealed significant gaps between the real and best practices as well as the mental reluctance and skill mismatch in delivering quality programming services. Given the persisting nature of identified problems, more research work should be done to catalyze a paradigmatic shift among industry players.

The environment in villages in Southwest China has been experiencing constant changes, indicating related change-inducing factors as well as their constitution and hierarchy. Starting from the classification of built environment according to Rapoport’s view, the “environment” consists of fixed, semi-fixed and unfixed elements (A. Fixed-feature elements: infrastructure, buildings, walls, floors, etc. B. Semi-fixed-feature elements: “furnishings” of the environment, interior or exterior, trees and gardens, fences, signs, billboards, lights, etc. C.Unfixedfeature elements: typically people and their activities, behaviors, etc.). Five representative historic villages in Southwest China (Zhenshan Village in Guizhou, Zhanglang Village in Yunnan, Moluo Village in Sichuan, Huaili Village in Guangxi, and Gongzhong Village in Tibet) were investigated to demonstrate the changes in terms of landscape in the last decade. This article provides an analysis of the dialectical relationship between reservation practices and evolving landscapes from a diachronic perspective. This analysis reveals defects of heritage conservation projects for historic villages in Southwest China. The results indicate the following: (1) there exists an important relationship between unfixed-feature elements of landscape and cultural heritages in historic villages; (2) semi-fixed-feature elements, although being neglected in most preservation practices, show strong sensitivity to mass tourism; (3) fixed-feature elements are highly vulnerable to civil engineering techniques; and (4) the most active change-inducing factors for evolving landscapes in historic villages include value orientations of villagers, relative locations of villages, ethnic groups, customs, and economic development.

This research demonstrates the suitability of applying Islamic geometrical patterns (IGPs) to architectural elements in terms of time scale accuracy and style matching. To this end, a detailed survey is conducted on the decorative patterns of 100 surviving buildings in the Muslim architectural world. The patterns are analyzed and chronologically organized to determine the earliest surviving examples of these adorable ornaments. The origins and radical artistic movements throughout the history of IGPs are identified. With consideration for regional impact, this study depicts the evolution of IGPs, from the early stages to the late 18th century.

The ever-increasing complexity of design processes fosters novel design computation models to be employed in architectural research and design in order to facilitate accurate data processing and refined decision making. These computation models have enabled designers to work with complex geometry and numeric design constraints to explore a whole new design field that is impossible to explore without computation techniques. However, most current design computation models follow an automation-oriented paradigm that only deal with strictly defined problem solving and optimization, but fail in establishing an intuitive and interactive communication with designers. This lack of interaction leads to an unconscious rejection ofnon-parameterizable design factors, which, reduces design computation models to specific design problem solving tools instead of operating as active design partners. This paper presents a non-deterministic design computation modeling approach derived from a discussion on quantum design paradigm, which employs real-time user interaction as the co-driver to evolve user+computation driven informed design outputs. A case study of such a design computation model; QPC Toolset, developed and applied in a QuantumPointCloud workshop, will be illustrated in this paper. Expanded discussions on fabrication optimization and constructiontechniques from the QPC workshop will be addressed to conclude a comprehensive report.
