The objective is to search for energy-efficient construction techniques suitable for this temperate and humid climate. This was pursued by analysing thermal comfort within building constructed from variety of modern materials. The wall constructions currently applied are introduced along with their dynamic and thermal properties. To analyse and compare the thermal behaviour and appropriateness of different building materials, a computer simulation is performed. The results from simulation analysis highlighted the important effects of thermal admittance and thermal mass along with u-value on thermal performance of the materials. They show that building with hollow clay tiles and lightweight concrete blocks with insulation had a better performance in achieving the preferred thermal comfort, while decreasing energy cost. This resear...

While air-conditioning is the most popular form of adaptation, natural ventilation is still relied upon for some parts. This study investigates thermal comfort performance of terrace housing in Kuala Lumpur, Malaysia, using Fanger’s predicted mean vote (PMV) thermal comfort index. A case study of a terrace house was carried out in a housing scheme in Kuala Lumpur where field measurement was conducted during a three-day recording in naturallyventilated space of the house. The study showed that the house was thermally comfortable for almost fifteen hours during day and night. Comfort conditions mostly occurred during night hours while around noon hours could be considered as critical times. To improve the thermal conditions, ceiling fans were used to increase the indoor air velocity. However, it was observed that this measure did not improve th...

This study investigates the impact of organic architecture in creating cultural spaces for children. The concepts of nature, naturalist architecture and children educational psychology, from the perspective of scholars and researchers in this area are investigated. The children’s perception of nature and their feelings were assessed and one hundred forty respondents among the instructors of cultural centres in different regions of Tehran have answered the questionnaires. To investigate the hypotheses, Univariate T - test and F - test were applied. The results showed that the stimulation of the natural environment has a positive and meaningful effect on curiosity, participation, and fantasy in children, while they show their impressions of nature indirectly. Therefore, designing applicable spaces according to children’s physics, using appropriate colours and furniture as well as more env...

Bazaars or business complexes were among the most important parts of city spaces, and always had great impact on people's lives and their architecture. Due to the expansion of cities, the concept of bazaar has changed, and is replaced by distributed spaces called shopping centres. This study was based on examining the problems and the shortcomings of today's bazaars from the perspective of clients and users and providing solutions to improve practical conditions. To this end, the descriptiveanalytic survey was conducted in Tehran, and 272 questionnaires were distributed and collected randomly among visitors in four shopping malls. To scrutinise the hypothesis, the correlation tests, single variable T-test, and F-test were applied. The results from assessments using SPSS16 software showed that the mere external similarity between an environment and form of an element or meaning cannot represent the properties of desired principles for citizens. Therefore, during the design stage, it is necessary to pay enough attention not only to the concepts of a physical form, but also to the mental picture and psychological aspects that audiences receive from an area.
