ABSTRACT: The built form of the traditional Indonesian house is considered to be a prime example of environmental design response to regional climate conditions. Recently, in general, modern small/medium housing types in Indonesia has not followed the same design principles. In comparison with their traditional counterparts, they are of a relatively heavyweight construction; they often suffer from low levels of natural ventilation. The indoor environmental conditions of the modern houses are, generally considered thermally unsatisfactory. This study is concerning thermal sensation evaluation for both, traditional types and modern style of housing in Indonesia. The ten traditional houses of Minahasa (North Sulawesi Province) and the ten modern style houses have been taken as house samples. 60 adults who were living in these houses have been taken as subject samples. Comparisons of thermal sensation response from the residents of these two types of housing may allow us in giving recommendations of housing construction quality and policy. The methods used in this research are numerical simulation (calculation of building heat transfer and thermal comfort) and field studies (questionnaires for thermal sensation and thermal environment measurement). Some of the results show that the respondents may feel thermally comfortable in an enclosure environment with a low air velocity where air temperature is in maximum of 29°C, with air humidity is about 60 %. By simulation, these climatic environments give a slightly uncomfortable condition, where the DISC scales are about 1 to 1.5. Therefore, there is a different about 1 scale between theoretical approach and field observation. Keywords: Traditional Architecture, Tropical Humid, Thermal Comfort

Materials Today: Proceedings, 2019
Rumah Limas Melaka which located at Chalet Warisan Puan, Alor Gajah was a traditional house that is still maintaining almost 70% of its traditional criteria. Traditional criteria of a building envelope design always become a concern about its ability to provide a comfort towards the users in this current climate. In this study, the focus was to evaluate the indoor thermal performance of this house, as well as to investigate and analyzed the indoor thermal condition by using psychrometric and heat index theories. A field experiment was carried out to obtain the needed parameters using thermocouple type J acquisition by HOBO logger, Anemometer, and IAQ Quest Temp34. The parameters were obtained at three different zones; A (rumah ibu), B (rumah tengah) and C (rumah dapur) for 14 days. Thermal energy calculation was done, and zone B was found as the most discomfort zone amongst others as it gains the highest energy needed to cool the space. Thus, it has least efficient of heat transfer due to the least ventilation provided and narrow in space that prevents adequate air flow from the outside. In overall, Rumah Limas Melaka shows to have a poor thermal performance yet still acceptable for the occupants with openings space allow easy passage of air and good cross ventilation.

Abstract: The Gayo Highland is one of the districts in Aceh Province, Sumatra. Due to the topography, this area has a lower temperature compared than the flat and coastal areas in Aceh. The thermal comfort that is felt is based on a person's mental condition and how he expresses his satisfaction with his thermal environment. In other words, it shows how humans adapt to their thermal environment. Thermal comfort based on human adaptation is known as adaptive thermal comfort. The form of dwelling for the Gayo Highland community has shifted and changed from traditional dwelling to Transitional and Modern forms that influence the Gayo Highland community's adaptation to achieve thermal comfort. Therefore, this paper aims to investigate the house design in Gayo highland in providing warmth to the occupants naturally in the cold environment. Another aim of this study is to investigate the people's habits in warming up the body to deal with the low air temperature in the area. T...
Study of Thermal Comfort in Traditional House Buildings (Case Study: Simalungun Traditional House)
International Journal of Architecture and Urbanism, 2021
Traditional houses were formed over a long period and are believed to be hereditary responsive to the surrounding physical and socio-cultural environment. Traditional Architecture is a building whose shape, decoration and method of implementation are passed down from generation to generation. Traditional architecture is a reflection of the values and culture that the community has interpreted. The adaptation of residents in the house is carried out by optimizing the positive potential of the surrounding environment and minimizing disturbances related to the comfort of living. The research problem is how the level of thermal comfort in the traditional house of Simalungun. The purpose of this study is to analyze the thermal comfort of the study object of the Simalungun traditional house. To determine the thermal conditions inside and outside the building, Measurements of temperature and humidity were carried out. Measurement data were analyzed and compared with Ecotech simulation data. The results of research carried out directly and simulating using Ecotech. This Simalungun traditional house can be categorized as having optimal comfort in terms of its physical physiological aspects and simulate using Ecotech simulations. As for the benefits of the research, it is hoped that it can provide knowledge about the thermal comfort of traditional houses, especially the traditional houses of Simalungun.
Building Design and Indoor Temperature Performance in the Humid Tropical Climate of Indonesia
Lack of adequate building codes in Indonesia has led architects and builders to build buildings without considering local climate. Designing buildings merely aims to satisfy clients’ aesthetical needs, whilst, on the other hand, sacrificing indoor thermal comfort and wasting energy. Measurements in two different buildings in Indonesia showed that these two buildings were performed unsatisfying indoor thermal conditions as the indoor temperatures were much higher than the outdoor. Local climates were neglected during the design processes. Most of architects and builders in Indonesia believe that achieving occupants’ thermal comfort in any building would be impossible without installing air conditioners (AC). Another study had been done in Tangerang, West Java, in which thermal measurements had been conducted in a house which was designed in such a way by implementing passive design approach. This study showed that even without AC this house was thermally comfortable. Using measured d...

Traditional Malay house has characteristics of passive thermal design which practices climatic design strategies. Currently, Urban Heat Island (UHI) cause energy utilization increasing for cooling purpose in the residential sector. Consequently, modern building construction has a poor passive thermal design. The aim to assess the thermal performance of Negeri Sembilan traditional house towards sustainable practice. The findings show house openings allow cross-ventilation, while house orientation towards climate factors contributes to the comfortable interior. This study highlights ideas and knowledge in improving the construction technology for modern architecture to produce an effective indoor thermal performance in a tropical environment.
Thermal comfort in the different settings of low-income dwellings in Surakarta, Indonesia
2010
As a preparation to develop guidelines and design principles for better dwellings in the tropics, a pilot survey was conducted to get data of the current situation of thermal comfort in the dwellings of low-income people in Surakarta, Central Java - Indonesia. These improper dwellings which locate nearby the rivers have ever been hit by big floods in the past and they obviously have very limited access to the green infrastructures. Research observed how people who are living in different settings of low-income dwellings will feel against indoor thermal conditions. Research was done in April 2009 when there was a dry season. As much as 64 respondents from two kampongs in Surakarta were involved. Survey included field measurements, interviews, and observations in the dwellings and surrounding environment.

KnE Social Sciences
This review discusses the thermal performance of traditional buildings in Indonesia. It is intended to see the impact of the traditional architectural design and its thermal comfort in the warm humid climate of Indonesia. The literature review was taken from 16 articles which cover Sumatra, Java, Kalimantan, Sulawesi, and the Nusa Tenggara region. The articles were classified into tropical climates (Af), monsoon tropics (Am) and savanna (Af) groups to identify which architectural elements in traditional buildings contributes to thermal comfort. Based on simulation and measurement in the field, it is found that the roof contributes to changes in temperature in the building.
Evaluation of Thermal Comfort in Traditional Houses in a Tropical Climate
A considerable amount of energy is being consumed for heating and cooling indoor environments in order to provide thermal comfort. For older buildings located in the southern parts of Iran, particularly in Bushehr, many climatic and passive design strategies are being used to provide indoor thermal comfort. This architecture and these elements have been developed in response to unfavorable weather conditions. The current study aimed to identify those passive elements and evaluate indoor thermal comfort in older houses. To achieve these objectives, passive elements in main houses located in the ancient urban structure were first identified. Then, a house in the coastal belt, Tabib's house, and another house inside the ancient urban structure, Nozari's house, were selected for the purpose of field measurement. The results revealed that the passive techniques used in these older houses significantly provide sufficient indoor thermal conditions. The mean measured predicted mean vote (PMV) of Tabib's rooms was 0.88 and the mean measured PMV of Nozari's rooms was 0.91, which were in an acceptable range. The measured predicted percentage of dissatisfied of rooms in both houses were lower than 10%. The main factor in creating indoor thermal comfort in these houses was the natural ventilation and its availability in the selected houses.

Traditional house is the ideal house according to the needs of a humid tropics climate like in Indonesia. But today many traditional houses was demolished for many reasons. This research attempts to make a simulation to see the thermal comfort of the two traditional houses in Kotagede with the different morphology house. The houses that observed are Dul Muin’s house and Samsuri’s house. The consideration for thermal analysis is the roofing, wall, floor material. Opening and layout of the site is also a factor taken into account in this analysis. Analysis were performed using the program CFD (Computational Fluid Dynamics). From the analysis results will be obtained that describe the morphology of the original traditional houses are most comfortable. The findings is expected to be a reference to build a modern house that adopt a traditional house by choosing a convenient morphological traditional house, so in order to obtain the expected thermal comfort.
