This paper focuses on the identification of layer mapping of Kota Lama Semarang through chronological development within decades of its construction since the early 17th century. The site was first settled as a relatively small fortress, changed into a massive huge fortress city, and underwent the demolition of the outer wall in order to face modernization and the Nederlandsch Indische hegemony in Indonesia. The newest layer of the map would be posted in the Indonesian independence era, where some major changes were applied in this area. After reviewing the history of ideologies in conservation, as qualitative research with the descriptive-analytic approach, this article employed heuristic method as its main approach. This article only discusses one aspect of the Historic Urban Landscape, which is the identification of layer mapping of the Oud Stad area through its chronological development from the 17th to 21st century. The other approaches would be recommended to further research as stated in the conclusion. The primary apprehension of this article is to examine the efficient and complete approach to preserving the urban heritage that complements the values and the ongoing traditions of the local dwellers.

This study provides calculation of OTTV (Overall Thermal Transfer Value) to multi storey building in Semarang. Case study for this study is Suara Merdeka Tower with the height of 15 floors and dominated by glass on its façade. In addition to OTTV calculation, recommendation provides as well in this study in an effort to reach ideal OTTV value for its façade. To minimize external thermal loads, SNI 03-6389-2011 determines the design criteria for building envelope with the Overall Thermal Transfer Value (OTTV) value must be less than or equal to 35 Watt/m2. The method used in this study is by direct measurement in the field using a measuring tool to get the effective temperature and relative humidity of the indoor space. As well as the use of Autodesk Ecotect Software 2011 as a tool that helps obtain Effective Shading Coefficient value with three-dimensional simulation by incorporating climatological data from weatherbase site.The result of this research is obtained OTTV value at each facade that is OTTV value on 9th floor southwest facade equal to 47,07 W/m2, on 10th floor southwest facade of 60,60 W/m2, at northwest facade 13,61 W/m2, on the northeast facade of 24.49 W/m2, on the southeast facade of 32.6vW/m2, on the eastern fasade of 32.32 W/m2, on the western fasade of 47.12 W/m2, and on the northern fasade of 32.32 W/m2.

This study aims to explore how traditional buildings of Indonesia adapted and responded to the current climate. Scientific publications regarding traditional houses from various regions in Indonesia were gathered to be examined the locality values in thermal comfort. The examination of the scientific publications highlighted some housing elements and arrangements that influence the thermal comfort of the houses. The building elements that affect the thermal comfort encompass lifted house on stilts; appropriate size and amount of windows; ventilated roof; selected natural material; divider arrangement; and the existence of veranda. Furthermore, as exemplified in Bali, the proper spatial arrangement between house buildings and open space influences traditional Indonesian houses’ thermal comfort. In conclusion, dealing with climate in a tropical area with high humidity can be demonstrated in those locality values without consuming excess energy for a cooling system. The significance of this study is beneficial for the development of tropical houses, which is expectedly to consider those locality values.

Studies about sustainable research remain increase recently due to the global trend and movement on greener lifestyles. Keywords on building, material, façade, and thermal represent the current issue in sustainable architecture. This study aims to trends in sustainable architecture research with specific keywords and periods. Publishing period between 1976-2020 with particular limitation applied to emerge 859 publication documents to be analyzed. Scopus’ on-site analysis system and VOSviewer were employed to generate graphical and visual analysis on research trends. The analysis results generate five significant research clusters: energy, façade technology, measurement, thermal, and climate. Besides groups, the analysis also indicates that most of the countries involved were from Europe. Hence, the conclusion of this study reveals potential research on a similar topic in tropical countries which demanding sustainable building encounters a humidity challenge. This study fills the gap in the bibliometric analysis regarding sustainable architecture with specific keywords and publishing period.
