“…Limited number of studies discussed the school courtyard and they were focusing on the ventilation, courtyard landscape role, adjusting the noise,…etc. [15], [16], [17], [18]. There was a gap in the literature related to the thermal effects of courtyards combined with the school buildings, as this was seldom discussed in the previous researches.…”

-Sustainability in architecture must produce buildings that give satisfaction for people with less energy consumption and less environmental problems. The sustainable design in architecture adopts passive design strategies like courtyards that produce buildings which use the wind for cooling and the sun for lighting and heating. The courtyard was a climate responsive design in the past, that provided people with easy direct solutions for their problems with the climate, and it was able to satisfy their social needs. In this study there will be an investigating for the effect of closed courtyard with different proportions on school building in UAE, to test the capability of the closed courtyard in improving the thermal performance of the school building consequently minimize the energy consumption. The study adopted a school building as a case study because courtyards are used mostly in houses while it can be beneficial for public buildings like schools. Courtyard can provide the school with private outdoor space, and can improve the thermal and ventilation properties of the school building thus minimize the energy consumption. Moreover the courtyard can provide the school with safe inner playground and learning scientific atmosphere for the students. The study will adopt a qualitative methodology which depends on descriptive and comparative analysis for the case study after the computer simulation with the Integral Environmental Solutions software (IES). After investigating the case study with different courtyard proportions and with the aid of the computer simulation, there was energy savings for the building because of the presence of the closed courtyard but with different values related to the proportions of the courtyard. The final result indicated that the courtyard effects the amount of the sun exposure, solar gain consequently the cooling sensible plant of the building, moreover the courtyard design and proportions have a direct effect on the ventilation beside the thermal performance of the interior spaces. However the courtyard should be in proportions that suits the height and the function of the building.

“…According to Shuzo Murakami et al [24], voids in the buildings bring advantages to the architectural, environmental and structural aspects, which can be summarized as follows: (1) indoor environmental control with a low environmental load using the potential of the outdoor environment will be possible. The voids will facilitate natural ventilation and enable the IAQ to be controlled; (2) solar shading performance will be improved by introducing voids in the buildings.…”

“…In the housing industry, natural ventilation has been of increasing concern, in terms of energy savings, economic considerations and sustainability in the built environment [1][2][3][4]. Numerous studies revealed that natural ventilation plays an important role in providing better indoor air quality (IAQ), thermal comfort and energy consumption in buildings [5][6][7][8][9].…”

Abstract:Enhancing natural ventilation performance in multi-storey housing is very important for the living environment in terms of health and thermal comfort purposes. One of the most important design strategies to enhance natural ventilation in multi-storey housing is through the provision of voids. A void is a passive architectural feature, which is located in the middle of deep plan buildings. It is very crucial to consider the configurations of voids in the buildings for enhancing natural ventilation, especially for multi-storey housing. In this study, Malaysian Medium Cost Multi-Storey Housing (MMCMSH), which is an example of multi-storey housing located in a suburban area, has been selected in this study. This study aims to investigate the potential of void for enhancing natural ventilation performance in multi-storey housing by the comparison of two different void configurations. Field measurement of MMCMSH has been conducted to validate Computational Fluid Dynamic (CFD) model and Atmospheric Boundary Layer (ABL) is an important parameter for setting up the CFD Model's domain. Ventilation rate (Q), which is necessary for comfort and health reasons, is an important parameter for the comparison of the different void configurations. This study revealed that the provision of void can enhance natural ventilation performance in multi-storey housing with an increase in the value of Q, from 3.44% to 40.07%, by enlarging the void's width by 50% compared to the existing void.
