VR is a new term to me. With a couple of words in brackets immediately after the abbreviation, (Virtual Reality) all is clear and well. Thank you to a colleague of mine. (See manuscript title CREATIVITY IN THE INITIAL PHASES OF ARCHIECTURAL DESIGN. Page 29 On the same level use of the abbreviation CD is more well known than the use of its actual meaning of Compact Disc.

In recent times, residential districts in modern cities face certain new and undesired problems related to antisocial behaviour by adolescents in its urban public spaces. In this study, we investigate the relationship between the design features of public spaces in residential areas and the problem of vandalism within the districts. This paper examines the current literature reviews on vandalism, the main reasons behind the increase of in the problem, types of vandalism, and a mathematical model for assessing visibility and accessibility in addition to proving the results of a field study conducted in a UAE city. We believe that visibility of vandalism-prone areas through dwelling windows, accessibility of such areas by residents through dwelling entrances, and recognition of ownership of such areas can definitely play a role in mitigating vandalism. Our findings indicated the following: (1) There is a strong relationship between vandalism and visibility through dwelling windows. (2) Residents' accessibility to dwelling entrances and recognition of ownership play an important role in reducing vandalism. (3) In areas where the visibility and accessibility by residents is low, the severity of the problem of vandalism increase if there is an increase in the percentage of adolescent residents. (4) The design characteristics of the housing areas, such as the height of the blocks or the limits of public spaces, do not have any influence on the occurrence of vandalism.

This paper conducted a study on the energy-saving potential of a developed thermotropic window. Office buildings in different climate regions of China were compared in terms of heating, cooling and lighting energy demands. Results show that annual heating and cooling energy demands for office buildings differ largely, while lighting energy demand at different climates keeps a significant percentage of the total energy demand, ranging from 36.1% to 66.3%. Meanwhile, thermotropic windows achieve a great advantage in improving daylighting performance and in reducing the overall energy demand, by reducing the overall energy demand by 2.27%-8.7% and 10.1%-21.72%, respectively, compared to movable shading devices and Low-E windows. This means that this kind of thermotropic windows have a great potential in applications in different climatic regions and can be considered as a good substitute of solar shading devices and Low-E windows.

The accessible nature of straw bale building lends itself well to self-built and workshop-built housing; straw is known to be both relatively inexpensive and easy to work with for people new to construction. A question then arises as to whether or not hiring an experienced builder can reduce overall costs of such a structure. This study conducts a worldwide survey to straw bale home owners to answer this question and to determine general economic data on straw bale homes, such as: what home owners value, who the main builder typically is, and what usually causes budgets to overrun. A key finding is that self-building is economically justified if the projected saving is higher than the cost of a contractor and if the usually longer time needed to build the home is amenable to the investor. An economic case study is also conducted on a straw bale home in Radomlje, Slovenia. All building expenses are categorized by building phase and subgrouped by cost in accordance with accepted building standards. A key observation is how demanding any specific building phase is in comparison to conventional building.

Creativity is viewed as vital for all design actions; however, creativity in general with its related cognition processes has no general theory. Creativity used in architectural design is different than creativity in other domains. This research proposes certain activities of the initial phases of architectural design, in which the role of creativity is distinguished. The research proceeds to present a case study of two architectural design studios in which a VR environment is employed in order to in-vestigate the effect of VR use on the creativity in those design phases. A methodol-ogy of qualitative and quantitative analysis has applied. Various architectural design factors are neutralized to overcome the influence generated from human factors variation and design thinking prejudice in architectural design and the associated ac-tivities.

The article explores the transformations low-income women make to appropriate their housing that often goes unnoticed. The aim is to document, acknowledge and make low-income women's efforts to appropriate their housing visible. Lessons learned are assumed to inform the Ugandan low-income housing discourse on design considerations that can contribute to the provision of housing designs that are conducive to low-income women. The study confines its investigation to the housing designs provided under the governmental low-income housing projects in Uganda.This article presents results from a case study on Masese Women Housing Project MWHP that targeted women as its main beneficiaries. Post Occupancy Evaluations POE methodology was utilised to collect data on the performance of the housing designs provided by the project and the transformations women make to increase their housing appropriateness. Open-ended interviews were carried out with women owners to investigate the transformations they apply to their houses. Results are documented through photography, sketches and measured drawings. Results are synthesised and analysed under outdoors and indoors transformations.The study confirmed the substantial contribution low-income women make to appropriate their housing. It argues for acknowledging and including women's efforts in the Ugandan low-income housing discourse to support the provision of housing designs that are more user-friendly to them. Design considerations that are essential to attain low-income women convenience with their housing are: its capacity to accommodate women's triple roles, their potential for incremental development and their ability for segmentation into autonomous housing units to allow for their flexible, economic and functional use. The study advocates for directing efforts to the development of traditional building technologies instead of introducing improved but alien ones as an alternative that is more favourable to women.

Housing has always been a significant aspiration of family expression and distinctly priciest investment by household. It plays a momentous role in the country's economy and so central to the societal well-being that is emplaced in the United Nation Universal declaration of Human rights. Yet in developed and developing world alike, cities struggle to provide decent housing for lower and middle income population. The provision of affordable housing is a major policy concern around the world with Malaysia being no exception; rising income hardly keep pace with price hike of housing unit and housing interventions has majorly concentrated on demand side leading to a non-responsive supply sector. Therefore, this paper highlights affordable housing issues pertaining Malaysia. It formulates Malaysian Map of affordability and conducts an evaluation of global housing schemes to better identify policy priorities for Malaysia. It's significant to harmonize supply and demand side factors in the housing market to ensure that housing supply fits the needs of citizens based on the location, price and target group. In case of Malaysia supply oriented initiative are of urgency in short and medium run. This must be supported by long term demand side schemes in parallel. Convergence of these two factors is essential for a balanced equilibrium and obtaining affordability.

Rural residential energy consumption accounts for 46.6% of total building-related energy consumption of China. In Northeast China, energy consumption for space heating represents a significant proportion of total rural residential energy consumption and has reached 100 million tce (tons of standard coal equivalent), or more than 60% of total household energy consumption. In terms of energy consumption per square meter of gross floor area, rural residential energy consumption for heating is more than that of cities (20kgce/m2). However, the average indoor temperature of most rural residence is below 10°C, much less than that in cities (18°C). Hence, it is an important task for Chinese energy saving and emission reduction to reduce rural residential energy consumption, while enhancing indoor thermal comfort at the same time.Restricted by local technology and low economic level, rural residences currently have poor thermal insulation resulting in severe heat loss. This paper reports on research aimed at developing design strategies for improving thermal insulation properties of rural residences with appropriate technology. A field survey was conducted in six counties in severe cold areas of Northeast China, addressing the aspects of indoor and outdoor temperature, humidity, internal and external surface temperature of building envelop enclosure, and so on.The survey data show the following:Modern (after 2000) brick-cement rural residences perform much better than the traditional adobe clay houses and Tatou houses (a regional type of rural residence in Northeast China – see figure A) in overall thermal performance and indoor thermal comfort;Among the traditional residential house types, adobe clay houses have better heat stability and thermal storage capacity than Tatou houses;Applying an internal or external thermal insulation layer can greatly improve rural residential thermal insulation properties, and is an economical and efficient solution in rural areas;In terms of roofing materials, tiled roofs show much better thermal insulation properties than thatch roofs;Adopting passive solar techniques can form a transition space (greenhouse) against frigid temperatures, resulting in interior temperatures 5.91°C higher than the outside surroundings. It is evident that local passive solar room design offers significant heat preservation effects and lower cost ($12/m2), embodies the ecological wisdom of rural residents, and is therefore important to popularize.The above experimental results can provide guidance in energy conservation design for both self-built residences and rural residences designed by architects. In addition, the results can also provide experimental data for energy-saving studies for rural residences in China.

Providing operational approach to end-users' motivational tendencies in housing facilitates user-centered approach enhancing person-environment congruence. The operational approach is highly critical in case of inaccessibility of end-users in decision making, i.e. mass housing. Therefore, this study aims at explaining end-users' housing motivations from their housing attributes preferences, through a theoretical framework developed based on Maslow's theory. The investigation was carried out by using a self-administered questionnaire conducted on 127 Iranian postgraduate students of Universiti Teknologi Malaysia, and their spouse who lived alongside them. They were selected from those who lived more than one year in mass housing apartments in Malaysia. Using exploratory factor analysis, the housing attributes preferences were analyzed to underlie the latent structure and relations among them; the extracted factors were also labeled based on the different level of needs. Then, conducting one sample t-test hierarchical tendencies among the different motivational factors were identified. Referring to Maslow's theory to explain the concept and characteristics of housing needs results in identification of two different categories of housing attributes in association with the different level of needs. Accordingly, primary levels of needs that associate with relatively tangible and concrete attributes are more likely to be content-specific and predictable. The higher levels of needs that associate with relatively complicated and abstract attributes are more likely to be problematical, confusing, and non-predictable.

Dhaka, the capital of Bangladesh has a recorded history of over 400 years, dating back to the Mughal and pre-Mughal era. A large part of the city's rich cultural heritage; both tangible and intangible, lie in the historic core known as Old Dhaka. There are several traditional neighborhoods with close-knit communities that date back two to three centuries. The communities are rich in social capital gained over successive generations of close social network. Based on this strength, a heritage management system has been developed by informal community bodies in Old Dhaka. Old Dhaka's rich cultural heritage deserves to be conserved for the historical continuity of the city. Unfortunately, the top-down conservation efforts undertaken by the Government are highly bureaucratic and have not been effective in conserving the cultural heritage in most cases. This paper explores the importance of local participatory approach of heritage management in the context of Old Dhaka with a focus on the relationship between social capital and informal heritage management in traditional communities. It also explores the key features that generally make the informal heritage management system more effective than the formal approach. Finally, it recommends an appropriate conservation approach to save the cultural heritage of Old Dhaka where there is a balance between intervention by authorities and continuity of local community involvement.
