“…In general, because of the ecological and energy efficiency reasons, the local material from the tropical traditional building has been adopted for common living space of the tropical modern building in an urban area. However, the adaption building material to the variation of the environment and its orientation has not been found in the previous studies [1,[14][15][16][17]. Therefore, by this research, the results are expected to reinvigorate local material in adapting to the changed environment for today's building.…”

The environmental problems of thermal and noise environment are recently considered the most important contributors to the tropical building in an urban area. The porous tropical materials provide both a solution for cooling and airborne noise problem from the source to receiver when the wind is in the same direction. This research optimizes the integrated control of thermal and noise environment which are directed into building material evaluation. Surabaya is selected as representative of the hotter area of the lowland while Malang is determined as the colder urban area of the highland. An eco-tropical lightweight material, wood, is examined as a case study. The field measurement for surface material temperature and its transmission loss were conducted in order to give information on thermal and acoustical properties of the material. The optimization is conducted by comparing Sound Reduction Index and by Conduction Heat Flow. The results highlighted that for the same material, the thickness that effect on its mass is important for both thermal and noise control. The higher the thickness is, the higher the Sound Reduction Index and the lower the conduction heat flow are. Modifying material by adding the thickness of wood results that by material mass minimum 36.5 kg/m2, the critical lowland building meets the standard of World Health Organization noise limits and has lower heat gain.

“…In the near future, in addition to previous studies [17][18][19], this study will be extended to review air movement requirement and to propose the updating standard of wind speed in restoring thermal comfort. Furthermore, it will be integrated with controlling airborne noise and support the existing guidelines.…”

The urban building standards recommend adaptable shift on heat and noise criteria as the main issues related to the high-density environment. The previous studies relating to building thermal comfort provided the comparison results between the past and recent conditions. This study reviews the guidelines and regulations of international standard, overseas countries, and specific region of tropical climate research in Indonesia. The evaluation is focused on tropical climate in order to reach the accurate thermal comfort and noise criteria comparison for Indonesia. Furthermore, the field study of the 71 of the tropical built environment respondents was also conducted in order to update and compare to the existing standards. The review results show that compared to 17°C to 31°C thermal comfort range from the World Health Organization, the tropical thermal comfort should be determined with a range of 29.3°C to 31°C. Based on the field studies, for lowland is formulated by 1.4x+29.3 and in highland is 1.5x+29.3 as two representative regions of the tropical environment. For noise criteria, some countries set the policy for determining noise limits which has the same value between day and night condition as the result of the constant number of noise source with the similar level of annoyance. Based on the field study, this study updates the noise criteria which the denser environment, lowland, has limits of noise in 49.9 dBA when in highland is 47.8 dBA. Both of them are lower than 55 dBA of Indonesian Standard. Noise perception by occupants in nighttime shows that both in the lowland and in the highland, the vote is lower than daytime. The noise limits are 45.9 dBA and 40.0 dBA for lowland and highland, respectively. In general, the updated standard completes the existing and the detail of Indonesia national standard and the will be useful to guide the tropical building design.

“…It is known that both acoustic problems that occur outside and inside the room are detrimental to users, in this case, it can disrupt the productivity of workers who are still using the hybrid system. Therefore, the stability of sound quality in the room, natural sound quality, and acoustic consistency in the room must be considered [7].…”

“…Based on these problems, this research is more concerned with interior acoustic problems. Acoustic material can be one of the solutions for optimizing excessive Reverberation Time and also as Noise Reduction, acoustic material is one of the most important aspects in determining the optimization of a room's reverberation time (Samodra, 2018). those requiring clear information delivery have a recommended reverberation time of 0.7 -1.1 s [10].…”

Environmental acoustics have an important architectural role that has a major influence on the productivity, health and sustainability of cities. living and proximity to the workplace have become essential needs for workers and entrepreneurs in today’s era. As many still work using the hybrid system, where workers require a comfortable living space as well as a comfortable workspace to support productivity, meetings and work can be done in the same place. SOHO apartments provide a solution to this problem, but they are prone to acoustic issues due to their open plan and loft concepts. The large volume of space requires special treatment, especially in terms of reverberation time. Excessive reverberation time can disrupt the productivity of residents and workers. A quiet space is needed to support these activities. This study aims to explain how environmental acoustics can improve the quality of a room and increase productivity and healthy through the application of acoustic absorbent material. However, the use of absorbent material is not very good for the environment if its use is not appropriate, therefore the selection of absorbent material must be analyzed carefully, so that what is obtained is PET (Polyethylene Terephthalate) material which supports all aspects of the SOHO apartment’s space needs and also material recycling up to 90%-99% which is good for sustainability. This study uses a combination method of observation and precedent studies. The results of this research involve the application of parameters to address acoustic issues in SOHO apartments and improve the acoustic quality of the space.
