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 Eco-House 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 an urban area, regarding the climate change issues, the tropical building and its occupants adapt to the critical context from the comfortable environment to the disadvantaged one
Adaptation of thermoacoustic environment has been analyzed by providing a tropical urban model as a case object
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
Summary
In an urban area, regarding the climate change issues, the tropical building and its occupants adapt to the critical context from the comfortable environment to the disadvantaged one. The adapted urban buildings exist in dynamic relationships among technology, human use, and the surrounding natural environment (Anderies 2014). A stronger driver should be a role for the built environment in natural processes, resilience, and robustness. The standard of the urban environment determines the different factors for the built environment such as thermal, indoor air quality, aural and visual environment comfort (Huang et al 2012). The wind could be a generator for both physiological cooling for restoring thermal comfort and environmental noise propagation. The tropical problems of heat and noise are considered the most important contributors to the indoor environmental quality
