Publication Daylight Efficiency And Energy Saving Lighting To Maximize Students’ ‘Hafazan’ Performance And Visual Comfort: A Case Research Of A Selected Religious School(Universiti Sains Islam Malaysia, 2021-10-06) ;Elina Mohd Husini ;Mohd Zin Kandar ;Fadli ArabiRaja Nur Syaheeza Raja Mohd YazitThe philosophy of Illumination and the scientific knowledge of light show the significant impact to energy efficiency and the development of performance in a building. It is important to improve the intensity of daylight in classrooms through introducing various innovative design of window in order to reduce the non- performance behavior of students. Current study shows the illuminance level within the recommended range of 300 lx to 500 lx or higher reduced the students’ Arabic handwriting speed based on word per minute. Further in the process of ‘hafazan’ as a memorization process, reading and writing task must consider sufficient window to-wall ratio, optimum daylight level and reduce the glare effect at the position of ‘hafazan’ setting at 300mm height crossed leg (‘rehal’) working plane and 900mm table working plane as a comparison. This research had conducted at Kolej Genius Insan, Universiti Sains Islam Malaysia, Nilai to identify the optimum illuminance level with window to-wall ratio of 30% and task performance at 300mm and 900mm working plane. Daylighting minimizes the artificial lighting with sensor or dimming strategies which can reduce by 19% during the passive daylight technique is applied. When the distribution of the daylight and illuminance level meet the uniformity at a lower working plane, the student’s performance is achieved within acceptable glare index. This optimum level of daylight performance range will benefit the designer to insert in the future of energy efficiency guideline and provide a sustainable building. - Some of the metrics are blocked by yourconsent settings
Publication Illuminance Level Measurement At Lower Working Plane Height In Islamic Religious School(Universiti Teknologi Mara (UiTM), 2020) ;Raja Nur Syaheeza Raja Mohd Yazit ;Elina Mohd Husini ;Mohd Khedzir Khamis ;Megat Faridrullah ZolkefliYakubu Aminu DodoIslamic religious school is an institution that integrates Quran hafazan (memorization) in the curriculum. Between 2011 to 2017, estimated that 900 new Islamic religious schools were established in Malaysia due to high demands. Designing a classroom layout that receives sufficient daylight is important because it influences the students’ task performance such as reading and writing. The standards recommend that any classrooms require an illuminance level between 300 lx to 500 lx when measured at working plane height between 800mm to 900mm, although the working plane height of rehal used for hafazan is between 250mm to 300mm. This study focused on the illuminance level measured at rehal working plane height for Arabic handwriting as a hafazan learning task in two selected standardised classrooms at Kolej Genius Insan. The students were required to rewrite the modified Balsam Alabdulkader-Leat (BAL) Arabic eye chart, where the students’ Arabic handwriting performance were evaluated based on their word per minute (wpm) scores. Both classrooms’ average illuminance level were 507 lx to 603 lx, which were too high based on standards and guidelines. The average Arabic handwriting scores for both classrooms were 9.4 and 12.6 wpm, which shows that the inefficient average illuminance level has caused the students’ performance to be very low. It can be concluded that the existing standardised classroom layout design was not suitable for hafazan learning tasks at rehal working plane height. Thus, the classroom layout design for Islamic religious schools needed further studies, which implicated the unsatisfied built environment of the classrooms and the school education for Islamic religious schools in Malaysia. - Some of the metrics are blocked by yourconsent settings
Publication The Occupants’ Visual Acuity And Performance: Methods For Measuring Occupants’ Visual And Writing Performances In Daylight Spaces(Scientific Academia Network, 2021) ;Elina Mohd Husini ;Raja Nur Syaheeza Raja Mohd YazitAwangku Abdul Rahman Awangku YussufAcceptable illuminance level in spaces is essential for optimum task performance that requires visual efficiency such as reading and writing. Passive design strategies are developed to meet the occupants’ visual comfort such as optimizing the daylight source. Previous researcher highlighted the illuminance level in a space correlates with the occupants’ performance, where the illuminance level which is higher and lower than there commended by the guidelines decreases the overall performances of the respondents. The guidelines and standards highlighted the acceptable illuminance level in office and school are between 300 lux to 500 lux. Various methods have been developed to identify the reading and writing performances of occupants in relation to daylight and illuminance level. This paper aims to study suitable methods that can be developed in identifying the occupants’ reading and writing performances in daylight spaces. The most common method to measure the respondents’ writing performance is the speed (minute) and word per minute (wpm) of the respondents to complete the writing task such as Handwriting Speed Test (HST) and Detailed Assessment Speed Handwriting (DASH).Secondly is to explore the changes of illuminance level whether has relation to visual performance. Therefore, the visual test is conducted to identify the task performance within the range of acceptable illuminance level. The students achieved the high visual performance not at the recommended level of illuminance. The changes of illuminance level of30 percent had influenced the student’s visual performance. In order to control the lighting strategy, the lighting systems and sensors in learning spaces are suggested to stable the light intensity and contribute to energy consumption - Some of the metrics are blocked by yourconsent settings
Publication A Review: Influence Of Natural Daylighting On Quranic Memorisation (Hafazan) Learning Task(ICIET 2018, 2018) ;Raja Nur Syaheeza Raja Mohd YazitElina Mohd HusiniIn Islamic point of view and other monotheistic religion such as Christianity and Judaism, light has been described as a sacred element. Surah An-Nur in the Quran emphasised light as synonym to Allah’s guidance. Interpreted by Buya Hamka, the first word of the first revelation “READ!” shows that in order to understand Islam, one must read and learn from the Quran. In Quran memorization (hafazan), the most acceptable method is reciting/reading and rewriting the verses. These methods or learning tasks are influenced by the daylighting condition of the classroom. Researches shows that sufficient daylighting improves the students’ performance such as cognitive skills, mood, behaviour and alertness. Those are the reasons that daylight is important and need to be considered in educational spaces. This review paper includes literature review on the preferred learning task for hafazan and the effect of daylighting towards students’ performance. The paper also refers to the traditional ‘madrasah’ method of hafazan, which uses a ‘rehal’ as practiced since the tenth century by the Seljuq dynasty. The recommended daylight in standards and guidelines are measured at 900 mm table height or working plane from floor level. Human ergonomics shows that clearance height for a cross-legged task is minimum of 300 mm, similar to the height of a ‘rehal’. The difference of height between a modern table and a ‘rehal’ shows that the illuminance level measured will be different. In conclusion, further study should be established in order to identify the acceptable illuminance level at different working plane height. - Some of the metrics are blocked by yourconsent settings
Publication Window design for optimum classroom daylight in islamic school(Universiti Sains Islam Malaysia, 2020-05)Raja Nur Syaheeza Raja Mohd YazitEfficient daylighting improves students' performance such as writing tasks in classrooms. Daylighting adequacy in the classroom is assessed through the standardized window design, which is 20 per cent of the Window-to-Floor Ratio (WFR). The illuminance level is measured at 800mm to 900mm working plane height with the window sill at the same height, where these are the variables focused by other researches on classroom daylight. However, the Islamic religious school that prioritizes the Quran memorization (hafazan) tasks through reading and writing Arabic language uses a low reading desk (rehal) with 300mm working plane height. Due to the current practice of integrating academic and religious subjects in classrooms, religious schools follows the standardised window design and table with 800mm to 900mm working plane height, where using a rehal will influence the illuminance level measured. The objectives of this research are to identify the acceptable illuminance level for students' optimum Arabic handwriting performance, to investigate the influence of window design on illuminance level measured at working plane of 300mm height, and to recommended window sill height for students’ optimum Arabic handwriting performance for learning hafazan at the working plane of 300mm height in Islamic religious school. Classrooms with recommended 20 per cent of WFR were selected, where three experiments with different window sill height and working plane height were conducted. The field measurement method to identify the average illuminance level of the classrooms was illuminance grid points measurement, where the lux meter was placed in a 1m x 1m grid layout of the classroom. The survey on students' perceptions of the daylight condition and task performances were measured through a five level Likert scale type questionnaire, while the Arabic handwriting performance test was conducted in the classroom to measure the students’ word per minute (wpm) using modified Balsam Alabdulkader-Leat (BAL) eye chart. The results then referred as the parameters for daylight simulation in Integrated Environment Simulation (IES) software to evaluate the window sill height for classrooms that uses rehal. The range of average illuminance level measure in the classrooms was 280 lx to 1600 lx. The questionnaire results show that the students accepted the illumination at the condition of 20 per cent WFR in the classroom. The Arabic handwriting assessment shows that students scored higher wpm in a classroom that received lower average illuminance level than recommended in standards and guidelines, which was 280 lx. The simulation shows that window sill height above 500mm exceeds the 280 lx average illuminance level, while window sill height between 300mm to 500mm received average illuminance level between 223 lx to 284 lx. Thus, the acceptable window sill height recommended for religious schools is between 300mm to 500mm. This recommendation will improve the standard design of Islamic schools by architects and designers, which will improve the students’ Arabic handwriting performance for hafazan learning process.
