Wind is known as one of the most mature renewable energies which reduces cooling energy in buildings and improves indoor air quality. Natural ventilation is one of solutions to prevent humidity disposal from the interior of the home. The shape and pattern of the air flow inside a room are influenced by two factors: the wind and the pressure difference caused by the temperature difference. Wind is taken into account in this study. Natural ventilation was studied using computerized simulation and the comparison of results in two sections. In the first section, bilateral ventilation simulation was performed in a residential apartment complex. In the second section, one-way ventilation was studied in the bedroom. The results indicate that both simulations require a driving force, which is wind, in order to have optimal mode and maximum wind circulation in the interior space. This wind can be supplied by architectural elements. Given that natural ventilation has not been much taken into account in recent years in Iran and no design guideline has been taken into account for engineers in this regard, such studies can help designers to understand renewable energies. This would help informed designing based on clean energies in order to reach better ventilation. In this regard, wind simulation was performed using CFD model by Design Builder Version 4.5

The lack of visibility and the difficulty in developing a cognitive map may be particularly important in wayfinding and in categories where the use of accessibility and sociability will provide a square suggestion in the Kuala Lumpur City Center Park (KLCC). This study attempted to examine the existing structure within the vicinity of KLCC and the transformations of its vicinity based on a square suggestion through morphological analysis using axial analysis and observations. The axial analysis shows how the accessibility of the square has shifted within the city and compares it with an existing park. Moreover, a square suggestion can provide context for the Petronas Twin Towers as a landmark and symbolic building. A square, as a regular geometry, can aid in improving the configuration of the vicinity of KLCC. Consequently, this research is useful to architects, tourism managers, and urban designers because it demonstrates the importance of effective factors in sustaining accessible and sociable space, such as a square

Legibility is based on landmarks and geometry. Visitors in a space learn to “read” an area by using three- and two-dimensional cues. This research aimed to determine the responses of visitors to the influence of geometry on the legibility at Kuala Lumpur City Center (KLCC). The relationship between geometry and space legibility can affect visitors׳ wayfinding. In this study, visitors, including 86 respondents and 8 individuals who participated in a focus group, were surveyed through questionnaires and interviews during daytime. Results show that legibility was moderately and positively correlated with regular geometry, but legibility was negligibly affected by existing geometry. Regression analysis, t-test, ANOVA, and scheme coding of qualitative data suggested that regular geometry used in urban spaces might strongly improve legibility. For urban designers, regular geometry associated with landmarks enhances legibility
