Abstract: Implementation of cross ventilation in highrise office building will face wind speed problem due to differences in elevation and system capabilities in creating wind distribution in the room. This paper examines the influence of apertures with configured distance on building facades against wind speed and wind flow distribution. It generated by using computational fluid dynamics. Performance of cross ventilation in hipotetical models were tested using calculation model k-e RNG. Enlarge the apertures dimension up to 40% window to wall ratio increase wind velocity in building without decrease wind distribution quality. Apertures with equal distance create good distribution of wind of up to 85% depth of building.Keyword:Â cross ventilation, tropical, cooling effect Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Abstrak: Implementasi ventilasi silang di gedung kantor bertingkat akan menghadapi masalah kecepatan angin karena perbedaan ketinggian dan kemampuan sistem dalam menciptakan distribusi angin di ruangan.

Pembangunan gedung ramah lingkungan telah digaungkan secara formal di Indonesia melalui peraturan menteri sejak tahun 2015. Untuk mendukung penerapan peraturan ini, pemerintah berinisiasi untuk menjadikan gedung pemerintah menjadi contoh penerapan prinsip bangunan gedung hijau (BGH). Salah satu gedung tersebut adalah gedung Kementerian PUPR di Jakarta. Upaya ini mendorong gedung-gedung pemerintah lainnya untuk berpartisiapasi dalam perencanaan gedung ramah lingkungan sekaligus mendukung pencapaian pembangunan berkelanjutan sebagaimana tercantum dalam Sustainable Development Goals (SDG). Kegiatan pengabdian kepada masyarakat (abmas) ini dilakukan untuk memberikan pendampingan dalam pengembangan perencanaan bangunan ramah lingkungan. Salah satu gedung kantor kecamatan/kelurahan di Surabaya dijadikan lokus kegiatan abmas. Kegiatan abmas dilaksanakan dengan menggunakan strategi seperti perekaman bangunan dan evaluasi kinerja BGH kantor. Hasil kegiatan lapangan dianalisis dan di evaluasi serta didiskusikan dalam kegiatan focus group discussion (FGD). Kondisi gedung kantor memenuhi syarat minimum BGH dan beberapa rekomendasi yang dapat diusulkan untuk meningkatkan kualitas BGH gedung kantor. Hasil abmas dalam jangka pendek dapat diimplementasikan khususnya penyesuaian/perbaikan yang tidak membutuhkan biaya besar, kegiatan membangun budaya ramah lingkungan dan dalam jangka panjang merealisasikan dalam bentuk progam fisik yang akan menjamin keberlanjutan kegiatan.

For museum and other exhibition designers, partitions are a crucial element in showcasing exhibition content. The massive partitions also serve to aid the acoustic performance of the space, by isolating the audio content. allowing visitors to better hear the audio content. On the other hand, designers tend to design pavilion spaces for maximum visual connectivity while considering circulation and space efficiency. This research examines the acoustic performance of three commonly used partition models to determine the relationship between partition openness and their respective acoustic environments. This research uses mixed methods to capture the instrumentalizing and perceptual aspects of humans. The objective method uses a digital raytracing simulation and impulse response tests in a 1:1 scale space model. This method describes the sound wave distribution and acoustic performance of a space in terms of several parameters. Conversely, the intersubjective method involved surveying 60 respondents to understand visitors’ perceptions of focus, distraction, and acoustic comfort within the pavilion space. The study demonstrates that a pavilion design with side partitions around 120 cm wide achieves the most optimum performance compared to designs with 240 cm side height partitions or no partitions. Furthermore, the research highlights the acoustic characteristics of the three fundamental pavilion models. These findings can inform people about the development of more tailored and versatile pavilion designs.

Vertical voids can enhance the performance of natural ventilation, improving physiological cooling and indoor air quality (IAQ), particularly in boarding houses as shared living spaces. The effect of void design on ventilation is influenced by various design variables, such as the proportion of openings, the void-to-building ratio, the void aspect ratio, and the void’s position within the building. The effects of vertical void towards ventilation efficiency can be improved by modifying these variables. This study investigates the impact of these design variables on ventilation performance through field surveys and microclimate measurements. Descriptive statistical methods were used to analyze the effects of different designs on two boarding houses. The results of the study can be considered in low-rise housing design as a way to improve natural ventilation performance. The findings show that CO2 concentrations remain stable at 400–600 ppm, which is attributed to low occupancy levels and large void volumes, regardless of the void design or air velocity. Airflow as an indicator of physiological cooling varied between day and night, with daytime ventilation being more effective on upper floors due to stronger thermal buoyancy and wind speeds. Nighttime ventilation was less effective, with weaker airflow, especially on the upper floors, affecting physiological cooling. Adjusting the void's aspect ratio can improve natural ventilation performance; narrower voids enhance upward airflow at night, while larger aspect ratios improve ventilation during the day.

A deep-plan office building design limits daylight access on the workspace distant from the side window. Horizontal Light Pipe (HLP) is one of the light transport systems that can deliver daylight to these areas. The research aim was to explain and evaluate the effect of HLP’s opening distribution area on daylight performance at deep plan-private office space. The research method was experimental with simulation as a tool. Daylight level and distribution of the base case, HLP with an opening distribution area of 6.6 m2 were compared with the case, HLP with an opening distribution area of 3.41 m2. The results showed that both cases distributed daylight uniformly. A 50% reduction of HLP’s opening distribution area, from 6.6 m2 to 3.41 m2 improved the average Daylight Factor as big as 6.42%. HLP with a smaller opening distribution area can be applied as the main source of daylight on deep-plan office spaces

In medium-rise office building on tropical climate, façade fenestration mostly dominated by glass curtain wall. In this case, an effort should be done to control the daylight penetration and to shade glare of low sun angle especially from west orientation. The idea is utilized the vertical greenery system (VGS) on facade opening, how it performs as glare limitation as well as accommodating view. Firstly, the variable of artificial shading to light parameter are studied. Then, the previous research of VGS were explored, to find its influential variables. The last step was developed recommendation of VGS implementation on office facade opening to improve light quality. Finding from the study, the most influential variables are the plant species suitable to the climate condition, its canopy leaves area as light variable, and the placement; an integration the plants construction system with other facade elements which consider light angles of incidence and viewer’s sightlines.

School buildings that use natural ventilation have challenges to Sick Building Syndrome (SBS) due to high noise intensity and the need to circulate air by opening windows. This study investigated SBS symptoms in schools closest to the airplane runway. Subjective measurements were carried out using self-administrative questionnaires to determine students’ perceptions. Objective measurements to obtain Indoor Environmental Quality (IEQ) data were carried out through an experiment of opening a window with an awning window type as far as 11 cm or 1/2 of the window span with an angle of 12.5. The average results of IEQ measurements on the thermal aspect include a temperature of 30.1 C, CO2 levels of 331 ppm, and wind speeds of 0.1-0.3 m/s have met the minimum comfort standards. However, the average humidity in the classroom has not been met. In addition, classroom noise is still far from the comfort standard, which is 70-109 dB. However, the results of the evaluation of students’ perception assessments of the IEQ of the room showed no symptoms of SBS in terms of physical and psychological aspects. Most students were not disturbed by the less-than-ideal thermal and acoustic conditions. However, students can experience long-term health problems and potentially experience psychological stress if they are continuously exposed to high levels of noise and less-than-ideal IEQ conditions.
