Abstract Climate change due to architecture occurs as a result of technological developments that support the development of materials, electrical mechanics, structures, and building shapes that play a role in increasing emission levels in the air. One type of building in Indonesia that contributes to increasing emissions is the residential building known as rumah susun. This research employs the case study method, observing the Rumah Susun Jatinegara Barat, located in East Jakarta. The case study shows that the use of prototypes that are not environmentally friendly makes a building’s performance worse. The use of precast, which resulted in monotonous window dimensions, is considered the main factor causing the failure of this Rumah Susun Jatinegara Barat to adapt to the surrounding environment. This problem occurred because the openings in the building façades had a monotonous dimension while the wind intensity that hit the building was increasing. The final result shows that the windows on the façades of the case study were not functioning except if all the openings in the residential unit are open. These results prove that the height of a building is an essential factor in planning high-rise flats, especially in Jakarta.

Survey Results

The discoloration of building facades due to airborne algae is observed in our surroundings. The growth conditions of these algae are not yet fully understood, and efficient measures for preventing the growth of the algae are not presently available. The objective of this study was to investigate the effects of the ambient environment and building structure on algal growth. A residential building in a cold region of Japan was surveyed. The roof was a multi-layered structure comprising a semi-transparent film, an air layer, and a layer of insulation from the outside, supported by rafters. The soiled state was visually observed by taking photographs. On the northeast (NE) and northwest (NW) roofs, several black stripes appeared 4 months after cleaning. The soiling increased in the spring and autumn. The soiling first appeared on the film backed by the rafter and then extended to the film backed by the air layer. The condensation time during the day in the rafter part was longer than that in the air-layer part. Condensation occurred during the night, but its frequency exhibited no dependence on the orientation of the roof. Algae tend to die when exposed to an environment with a temperature higher than 45°C. The NE roof had the shortest period with a surface temperature of >45°C. These measurements agreed well with the survey results, which indicated that the soiling mainly occurred on the NE and NW sides of the roofs. The time for algal growth was estimated under the assumption that algae can grow at surface temperatures ranging from 0 to 45°C, in agreement with the observed soiling. The observed soiling changes were well explained by the algal population calculated via a growth predictive model according to the algal temperature and relative humidity.

Abstract In this paper, transient analysis on heat transfer across the residential building roof having various materials like wood wool, phase change material and weathering tile is performed by numerical simulation technique. 2-dimensional roof model is created, checked for grid independency and validated with the experimental results. Three different roof structures are included in this study namely roof with (i). Concrete and weathering tile, (ii). Concrete, phase change material and weathering tile and (iii). Concrete, phase change material, wood wool and weathering tile. Roof type 3 restricts 13% of heat entering the room in comparison with roof having only concrete and weathering tile. Also the effect of various roof layers’ thickness in the roof type 3 is investigated and identified that the wood wool plays the major role in arresting the entry of heat in to the room. The average reduction of heat is about 10 % for an increase of a unit thickness of wood wool layer.

AbstrakKelantan terletak dalam pengasingan dari koridor perindustrian di pantai barat dan jauh dari pengaruh KualaLumpur, Pulau Pinang dan Singapura. Adalah penting untuk menentukan daya-daya penentu pertumbuhanbandar di negeri ini kerana pusat-pusat bandar di Kelantan mempunyai gabungan unik antara potensidan kekangan. Walau bagaimanapun, sebagaimana proses globalisasi dan urbanisasi perbandaranyang berlaku di seluruh dunia, evolusi senibina di Kelantan tidak terkecuali dan pemeliharaan nilai-nilaisejarah yang unik perlu dilakukan. Warisan senibina Kelantan hari ini kurang dihargai oleh masyarakatkerana karaktornya yang terpencil dan kurang baik. Hal ini kerana proses pengekalan bangunan warisankurang diberi perhatian dan juga kurang mendapat penekanan daripada pihak berkuasa dan masyarakatsendiri. Terdapat banyak bangunan-bangunan bersejarah di Kota Bharu yang telah dirobohkan untuktujuan pembangunan bandar dan ada sebahagian bangunan diberi pengaruh gaya seni bina modendan kontemporari tanpa mengambil kira nilai sejarah yang sedia ada. Pertumbuhan intervensi senibinaadalah tidak dapat dielakkan atas permintaan untuk memenuhi keperluan perbandaran. Akibatnya, corakpersekitaran bandar dan warisan senibina ini mengalami perubahan sepanjang proses pembandaran.Selain itu, perubahan telah memberi kesan kepada suasana persekitaran iaitu bangunan (warisan alambina), serta perancangan jalan dan aktiviti. Abstract Kelantan is situated somewhat in isolation from the industrial corridor of the west coast and far from thesphere of influence of Kuala Lumpur, Penang and Singapore. It is important to determine the forces of thestate’s urban growth determinants because urban centers in Kelantan have their unique mix of potentialsand constraints. However, as far as globalization and urbanization that are taking place worldwide, thearchitectural evolution in Kelantan is not exempted and the preservation of any unique historical valueshould be done. The heritage architecture value of Kelantan today, has not been appreciated by localfolks and society because of its isolated and poor characters which has not been maintained and wellemphasized by the authority and society themselves. Hence, the remarkable heritage property has been‘invisible’ and demolished due to negligence and time factors. Moreover, there are many historical buildingsin Kota Bharu that had been demolished for urban development purposes and the influence of modernand contemporary architecture style without considering the existing and distinctive of historical value.The growth of architectural intervention is inevitably due to society and its demands to fulfill their urbanneeds nowadays. As a result, the pattern of urban setting and heritage property had changed throughoutthe years of urbanization. Moreover, the changes have affected the ambiance of surrounding i.e. buildings(built-heritage), and streets planning and activities.

The rate of air pollution is becoming a cause for worldwide concern because of its substantial increase. Different sources like combustion of fuels, release of smoke from industries etc are responsible for the pollution of air. The construction industry is a major contributor to air pollution in the form of dust. Most of the activities involved in the completion of a construction project contribute to the generation of dust in one way or another. There are many sources of dust in a construction site like the use of construction equipment, transportation activities etc. the dust thus generated can ill effects as well. But, the problem of dust pollution is not addressed properly mainly because of the lack of awareness in this area. Proper identification of sources of dust in sites, its health impacts etc can help generate awareness and also help in implementing control measures. This can help reduce dust pollution on site. Here, a residential building site is taken for the case study. A questionnaire survey is conducted for the workers to identify the negative impacts construction dust has and also to determine the most common dust control measures employed in site.
