The study on which this paper is based developed a simulation model, using system dy- namics methodology, to assess the sustainable performance of projects. Three major factors are used to examine project sus- tainable performance (PSP): the sustainability of economic development (E), the sustainability of social development (S), and the sustainability of environmental development (En). Sustainable development ability (SDA) was used as a prototype to evaluate the degree of sustainable performance. The simulation software ‘ithink’ was used to help with the application of the model to a real life case. This paper explains and demonstrates the procedures used to develop the model and finally offers an approach for assessing the feasibility of a construction project in terms of its sustainable performance.展开更多

Kadir Has University building has been selected as the case study of the research. Success of the conversion and interventions in terms of sustainability will be discussed. The aim of the study is to question adaptive reuse project of the Cibali Tobacco Factory as university within the framework of urban regeneration of Cibali district. The relation between adaptive reuse projects and its relationship among socio-cultural, economic, and physical dimensions of the sustainability, also its effects on the environment and region has been discussed. Adaptive reuse examples should not be accepted as single projects. Its contribution to the environment and the region is also crucial. Preservation of an individual building can be a catalyst to renewal of others. It can help the transformation of the whole area. There is always an interaction between the conversion projects and the environment. In order to achieve a successful conversion, appropriate functions should be given to the industrial heritage buildings according to the needs of the region.展开更多

The concept of habitat, in fact, implies issues of dialectic spaces, in other words, those settings that can be defined as relational subsystems within the urban/domestic scale. This essay has its roots in the CIAM （Congr^s International d＇Architecture Moderne （in English： International Congress of Modem Architecture）） of 1953, during which the complementarity of the outside space next to the dwelling and its relevance within the project discipline, have been affirmed. In particular, assimilating the lesson of Aldo van Eyck, this work investigates the deepest issues of the concept of threshold. The analysis makes use of the work-tools of critical reading and comparison between urban and rural habitats, with different density levels, whose relational fabrics have been layering over time permeable ＂thicknesses＂ which articulate complex threshold spatial configurations.展开更多

In fact, it may create new centralities and give new collective function for deprived areas. The case study of the architectural and educational project for a new museum park devoted to the technique and the science in the Apennine＇ s landscape near Parma （Italy） may give an interesting point of view about the role of the teaching and the research of the architecture in the former industrial heritage, and to avoid the abandonment and the pauperization of the territory around.展开更多

The building brick game chosen for analysis was the Arckit, since it is suitable for the architectural practice. It is estimated that this game can contribute to the design, representation and presentation of projects. In order to investigate in which aspects Arckit presents possibilities of applications, as well as limitations of use, the article approaches the importance of building bricks as a didactic tool and its use in the field of the architectural design process. From a literature review and an empirical experience, this article reports a qualitative research, where the applicability of the Arckit game was checked. Through a critical reflection based on that experience, it was possible to conclude that whereas its limitations to urban form and linked to the formal vocabulary that composes the grammar of these bricks, the Arckit building bricks represent in architecture a playful and experimental way to think and design, fomenting the creativity and the spatial perception, resulting in a particular experience that can make architecture better connected with dreams and joy.展开更多

The indoor air quality and thermal comfort were measured at various selected locations by using indoor air quality equipment （Thermal Comfort SERI）. The thermal comfort assessments are based on Malaysian Code of Practice Indoor Air Quality 2005 and Moderate Thermal Environments-Determination of the PMV and PPD indices specification of the condition for thermal comfort （ISO7730：1994） From the data analysis, the FKAB building is considered inadequately vented space. The concentration of CO2 for all sampling area evaluated exceeds the recommended concentration （〉 1000 ppm）. The ventilation system used in FKAB building is designed by delivering fix amount of fresh air into building from external building without consideration on the number of occupants. This common ventilation design will increase the amount of CO2 dramatically all day long and these reflect the inefficiency of energy used. The faculty needs to be equipped with a comprehensive energy management system that can allow detailed documentation of continuous performance of all energy system and consumption in the building.展开更多

But in architecture, the students are not used to start up with biological investigation. Instead of analogues, it is permitted to pursue an evolvability systematics for built emerge. The systematics relies upon the key assumptions of Kirschner who sought the characteristics of biological evolution. For an integrated design thinking of an architectural mind, this is a methodological study, which strategically adapts living forms＇ evolvability capacity to built-forms＇ structural emergence. The study outlines the evolution strategy with experimental studios of building and design. The preceding systematic is taught in distinguished courses. It is purposed to build an easy-to-apply framework for how to generate novel structures and how the spatial structure units are organized to emerge with an imagined nature as novel tectonic model. Besides, building up structural thinking into the consilience of evolution strategy, the study is also distinguished for understanding the value system of architectural mind to diagnose the genuine character of inventive built form. Strategy constructs processes. Thinking strategy concludes by the evolvability directives of studio assignments and they are given as flow-charts and project models.展开更多

Because of many and various achieved business successes by different working groups as well as the methodology geographical dispersion throughout the world. Multi-faceted Kansei has been developed for the last 20 years in a very wide and varied way. The Kansei has experienced as if talking of a tree, a branching experience still going on nowadays. Today we can speak from Kansei in theory, Kansei emotion measurement, Kansei engineering, Kansei information, Kansei education, Kansei design to Kansei in practice and many other disciplines. Three years ago, our team started the experience to introduce Kansei in the educational atmosphere, applying it to the final degree projects. In the School of Building Engineering at the Universitat Polit^cnica de Valencia and inside its final degree project proposal, a workshop on Kansei engineering was offered. During these years at the eighth semester of the building engineer degree, students have been working for almost five months under the supervision of a team of teachers on their final project till the final public oral defense was made in front of a committee. During these years, we have worked with an average of 10 students per year. Some have successfully completed their final projects, others have not achieved the minimum required. The article aims to explain the experience during the last three years the team has accumulated in Kansei education, and can be of interest for every teacher or lecturer.展开更多

It aims to make mud bricks lightened with good mechanical, thermal and sound properties and enhance the waste polystyrene. This article is the result of experimental work on a broad field of applied sciences： building mechanics. The study is focused on BTS （blocks of stabilized earth） chosen as reference materials to which we linked polystyrene. The percentage of polystyrene varies from 0% to 100% starting from a constant volume of each reference material. The results showed that the increase in polystyrene percentage lowers mechanical properties. These results also showed that the gradual addition of polystyrene to the laterite-cement mixture has a significant influence on the density and mechanical resistances of the final composite material.展开更多

Based on this finding and by including the energy principle of rock fragmentation, the logarithm distribution model of particle size is formulated, which uncovers the natural characteristics of particle sizes on statistical distribution. Exploring the properties of the average value, the expectation, and the unbiased variance of particle size indicates that the expectation does notequal to the average value, but increases with increasing particle size and its ununiformity, and is always larger than the average value, and the unbiased variance increases as the ununiformity and geometric average value increase. A case study proves that the simulated results by the proposed logarithm distribution model accord with the actual data. It is concluded that the logarithm distribution model and Kuz-Ram model can be used to forecast the particle-size distribution of inartificial rockfill while for blasted rockfill, Kuz-Ram model is an option, and in combined application of the two models, it is necessary to do field tests to adjust some parameters of the model.展开更多

The stratigraphic system of the study area is established by using latest high quality seismic reflection and deep borehole data. Characteristics of the major faults developed in the study area are finely depicted with the method of structural analysis. Tectonic evolution of Xiong'an and adjacent areas is reconstructed by using balanced geological cross-section technique. The tectonic activity of the study area is discussed on the basis of the development of secondary faults and the distribution of active earthquakes across the region. This study demonstrates that Xiong'an New Area is located at the transfer zone of the central and northern Jizhong Depression. There are three regional unconformities developed in this area, by which four structural layers are sub-divided. Controlled by the Taihang Mountain piedmont fault, the Daxing fault, the Rongcheng fault and the Niudong fault, the structural framework of the study area is characterized by intervening highs with sags. This structural pattern has an important controlling over the reservoir characteristics, hydrocarbon accumulation and the distribution of geothermal resources and hot dry rock within this region. Rifting in this area began in the early Paleogene, exhibiting typical episodic character and became inactive in Neogene. The development feature of secondary faults along with the distribution of active earthquakes indicate that Xiong'an New Area has been in a relatively stable tectonic setting since the Neogene, while the Baxian Sag and other structural units to the east of it have obviously been in a rather active environment.展开更多
