“…Through field experiment and mathematical calculation referring to the standard, this research points out a conceptual design of tropical urban model on integrated design of thermal and acoustics issues which consist of thermal performance and urban community noise control. In line with the previous finding (Samodra 2016), the results recommend that the noise barrier of the building should consider 5.24% of the maximum window to wall ratio (WWR) horizontally and vertically. In addition, vertical ventilation is the best solution for urban density, but the orientation and its flanking noise effect to the passive cooling.…”

Abstract. Climate and urban environment changes lead to tropical building adaptation and resilient strategy. They focus especially on thermal comfort and noise propagation variation as the result of global warming and urban growth. This study analyzes a conceptual design of tropical urban model on integrated design of thermal and acoustic (thermoacoustic) issues. By experimental measurement and simulation method using Computational Fluid Dynamics, the findings are directed to meet the standards and to recommend the new guidelines for sustainable urban building. The research location is in Surabaya as the urban tropical lowland area and EcoHouse of ITS, a tropical building model in an urban environment, was built as experiment model. The results highlighted that the noise barrier should consider 5.24% of the maximum window to wall ratio (WWR) in tree dimensionally analysis, horizontally and vertically. Providing vertical ventilation is the best solution for urban density, but the orientation and its flanking noise affect the passive cooling. In general, there are some factors having a high contribution in addition to WWR, such as wind acceleration, the distance, and building material.

“…In fact, there is a lower wind speed in the upper part of the room (<0.4 m/s), but the lower air temperature is still distributed evenly (27-29°C for lowland). This is in comfort zone (24.3-29.3°C in average) based on the Psychrometric chart analysis (Samodra, 2016). A small problem is only found in underheated condition of highland building (the lower part of highland building gets 23-25°C).…”

“…Except for harder activity conducted in additional room, the other zones have 0.5 of PMV. Therefore, as analyzed by minimum wind speed, 0.8 m/s for physiological cooling, it should be improved by ventilation as proposed building design (Samodra, 2016). …”

With large open space, traditional houses as representative of rural architecture, have been designed in the past in sufficient air flow. However, nowadays, they fight to accommodate unsupportive environment; high density neighborhoods and global warming effect. This research studies adaptation method and concept of sustainable design of the rural architecture in urban environment of tropical climate. Simultaneous direct measurement and occupant interview were conducted on 19 buildings and 71 respondents. Ecotect Analysis and CFD Fluent program were also used to obtain the proposed model. The results highlighted that by active and passive ventilation method, the occupants respond their urban environment. Moreover, the sustainable design can be reached by raising the floor and roof in order to give higher potency of cooler sufficient air movement through openings and shading. Providing solar chimney as vertical ventilation with sufficient ceiling fan works is also proposed.

“…Hal ini terjadi karena biasanya kota di dataran rendah (lowland) tumbuh lebih cepat daripada kota di dataran tinggi (highland). Hal ini memiliki konsekuensi tidak hanya terhadap variasi penyebaran kebisingan dari luar ke dalam bangunan, tetapi juga adaptasi penghuni dan rancangan arsitekturalnya (Samodra, 2016). Dalam, hal ini, material dan WWR menjadi elemen selubung bangunan yang memegang peranan yang penting.…”

Dalam lingkungan perkotaan, penghawaan dan kebisingan merupakan faktor yang paling penting dalam mempengaruhi lingkungan dalam bangunan. Penelitian ini mengkaji WWR (Window to Wall Ratio) sebagai kompromi kebutuhan penghawaan dan pengendalian kebisingan rumah Jawa yang menjadi studi kasus dari hunian tropis lembab. Kebutuhan luas bukaan (WWR) memiliki perilaku yang kontradiktif, yaitu antara kebutuhan bukaan maksimal untuk aliran angin dan minimum untuk mengurangi kebisingan. Lokasi penelitian ini berada di dataran rendah (Surabaya, 0-50 m msl) dan di dataran tinggi (Malang, 440-667 m msl). Kedua kota besar tersebut dipilih karena memiliki kemiripan budaya dan arsitektur. Hasil penelitian ini menunjukkan bahwa rentang WWR sebagai bentuk integrasi pemenuhan kebutuhan penghawaan dan pengendalian kebisingan, yaitu dataran rendah/siang hari: 0.13-100% (standar survei), 0.13-5.24% (standar WHO); dataran rendah/malam hari: 0-100% (standar survei), 0-3.24% (standar WHO); dataran tinggi/siang hari: 0.24-100% (standar survei), 0.24-70.48% (standar WHO); dan dataran tinggi/malam hari: 0-100% (standar survei/standar WHO).
