Abstract - Facade is one of the elements in architecture that has a role in the thermal comfort of spaces in buildings. Facades have a variety of shapes and types that have their respective roles. As the development of facade technology can be developed with the help of mechanical engineering, industrial, and computer engineering. One of them is the dynamic facade of the Al Bahar building, Abu Dhabi, which uses technology such as computer programming to regulate the size of the facade's opening to the climate which is read by heat sensors which has the effect of reducing heat on the building's interior and reducing energy for artificial ventilation / air conditioning purposes.The shape of the triangle folds that are designed can close and open fully for visual interest in the inner space. It is estimated that the facade is able to reduce more than 50 percent of incoming heat and reduce the need for air conditioning in buildings. The purpose of this research is to study the workings of dynamic facades that use computer technology and also examine effective materials for use in Indonesia's tropical climate. This research used quantitative and experimental methods of facade mockup design. An experiment was made of facade mockups that were able to move similarly to the movements of the facade of Mashrabiya, Al Bahar, which required programs and computer coding to support movements that were adaptive to the surrounding climate. Keywords: adaptive, dynamic, facade, thermal

Abstract - The building envelope is one of the important building elements to create indoor thermal comfort of the building because it interacts directly with the environment outside the building. Double skin facade is one of the building envelope design strategies that not only be used as part of the building facade design but can also be used to increase the indoor thermal comfort of the building. Along with the development of technology, design of the double skin facade is also increasingly diverse and developing, one of which is the material technology used. Phase change material is a material that is quite renewable and can be applied to various building elements such as building envelopes or double skin facades. Phase change material is a material that has the ability to release and store latent heat energy for a relatively long period of time without experiencing a change in temperature. Phase change materials have the ability to change phase from liquid to solid or vice versa. Some types of phase change materials have a transparent character so that this character can be utilized and applied to transparent building elements such as building envelopes or double skin facades as a strategy to increase the indoor thermal comfort of the building. This study aims to determine the effect of the application of phase change materials on the building's double-skin facade on the thermal comfort of indoor buildings in the city of Bandung. phase change material itself is a material that has not been widely applied, especially in the world of architecture so that research on phase change materials can increase knowledge about strategic innovations to achieve thermal comfort in buildings. This type of research is quantitative research with experimental methods using digital simulation. Experiments with digital simulations were carried out using Design Builder and EnergyPlus software. The analysis is carried out by comparing the conditions of the simulation model before the application of the phase change material on the double skin facade and after the application of the phase change material on the double skin facade. Based on the analysis process, it is concluded that the application of phase change materials can increase indoor thermal comfort. The alternative double skin facade design with a phase change material has an average operating temperature change effect of up to 7.34% compared to a room without the use of phase change material. Keywords: phase change material, double skin facade, indoor thermal comfort

Abstract - The issue of limited urban land in Indonesia is increasing day by day, with the problem of high population growth and increasing housing needs, creating a lot of slum housing which does not pay attention to comfort and health. With this problem, the city also produces many smaller building widths and land compared to the previous one, especially in the city center and its surroundings. Nowadays buildings around urban areas in Jakarta are smaller but elongated on the sides , which uses a flat roof to add to the city view, with an elongated shape of the building that does not have openings on the right and left sides, this raises questions about the system and the building's performance on thermal comfort. This study uses a software simulation method, where the 3d model is made on Autodesk Revit, while the simulation is carried out to analyze the model thermal comfort and wind speed, using Autodesk CFD software. For the assessment of wind speed ,it is verified with the Lippsmeier 20017 standard and the thermal comfort standard through the Indonesian thermal comfort standard in (SNI) 03-6572-2001 and the Regulation of the Minister of Health of the Republic of Indonesia NO. 1077/MENKES/PER/V/2011. The results of this study are an optimization model and a simulation of the application of effective shading and stack effects in buildings, especially in the main room in the long building, in this study the object used is 3500mm house by Ago Architects on Jl.Haji Nawi, South Jakarta. The optimization simulation of the facade components and the stack effect in the building was carried out 4 times with the parameters of the shading angle (A and B) and the height of the stack effect (A and B), followed by concluding that from the 4 simulations the greatest effect for achieving thermal comfort is optimization of the stack effect which can reduce the comfort temperature by 1.56°C. The conclusion in this study is that optimization of the Stack effect can make the thermal comfort of the building better.

Abstract - The comfort of a building is a supporting role for the user’s activities. Student activities at school, especially kindergarten students, have activities that tend to use more of a higher metabolism, so a comfortable space is an important aspect of user activity in a room for a learning environment. The object used as a study is KB-TK Pahoa Tangerang as a school where the building maximizes passive design to support teaching and learning activities. Thermal discomfort caused by high temperatures can be a distraction and have a negative impact on the teaching and learning process. This study aims to look at thermal comfort in kindergartens located in tropical environments and activities that use a lot of physical activity for learning at the kindergarten level. In this research an experimental method will be carried out using CFD (computational fluid dynamics) simulations and including activities in kindergarten to address the problem of thermal comfort, especially for children aged 4-6 years. The analysis was carried out using the PMV (predicted mean vote) which in this process included activity variables, clothing, and building physical data to determine user satisfaction and classroom thermal comfort. Direct observation of the location of the study object was carried out to obtain existing data and literature studies for reference regarding thermal comfort and passive cooling strategies. The results obtained from this study indicate that the conditions of thermal comfort in the kindergarten from morning to noon, students using the classroom show slightly warm thermal sensation. Based on the results of the existing simulation, it is continued with efforts to optimize the design to achieve thermal comfort by optimizing it through modification of the classroom model using sun protection (shading) & ventilation. The optimization percentage reached the maximum value of PMV reduction by 12,68% in ventilation optimization, and 6,55% in shading optimization.

Abstract - Preservation efforts can be done through active or passive mechanisms to safeguard and preserve. The existence of the environment in the gallery space, which includes features of humidity, temperature, and airflow, has a great influence on the preservation factor for works of art, where this matter influences the sustainability of the existence of works of art that are stored. Fine arts museums in Indonesia are frequently found to be lax in their efforts to conserve what should have become normal practice, perhaps causing damage to existing pieces of art. This study employs quantitative and experimental methods, including Autodesk CFD simulation trials that generate a description of the existing condition of the study object and its relationship to the influence of work of art preservation, as well as simulation trials of the influence of existing design developments that are aligned and compared with work preservation theory guidelines. art. Field observations and literature searches were used to acquire data. Data are organized according to research variables, which include features of artwork preservation in museum settings, humidity-temperature-air flow, artwork preservation support systems, and space design development. The analytical technique employs distribution simulation in conjunction with the idea of guidelines for the preservation of works of art, as well as simulations for optimizing the design of interstitial spaces, which aid research in developing scope for better preservation. The research found that the performance of the design of the layout of the museum space might influence the existence of the gallery space's climatic conditions, which affect aspects of preservation efforts and the condition of the works of art in it. The architecture of the museum's spatial organization must be able to prevent as much of the impact of the external climate as possible and establish stable indoor circumstances so that climate changes do not occur, undermining efforts to preserve pieces of art. It was discovered that the optimum design of the implementation of the interstitial space or airlock can be a solution to the preservation effort problem, and has been shown to be capable of producing climatic conditions in interior spaces or structures that tend to fall and are in a constant or stable state. The overall implementation of the inter-room design can reduce the presence of airflow by 99.54% and the temperature by 2.04 'C, decrease airflow and temperature from the outer enclosure to the airlock lobby by -83.67% and -4.62%, internal airlock space by -98.26% and -5.25%, and museum space by -99.54% and -5.79% Keywords: Preservation, works of art, humidity, temperature, airflow, spatial, arrangement, constant
