Title: The Performance of Niang House in the Tropical Highland of Manggarai District Niang home is one of the ten varieties of Traditional Architecture in East Nusa Tenggara Province located in the highlands of Manggarai district (800 - 1200 meters above sea level) with its peculiarities, namely the circular floor plan and a conical roof. Niang home is growth by people with all kinds of traditions and utilize a variety of local potentials such as materials, technology and knowledge. But local potentials such as the use of lightweight materials such problems occur in upland areas that tend to be cold because the thermal properties of lightweight material is loose and flowing out so that it can potentially create underheating and conditions affecting comfort conditions in buildings. This study aimed to evaluate the effect of house design of Niang in response to thermal conditions in the highlands and analyze the behaviour of the material of the design elements that affect the thermal performance of the house of Niang. The study was conducted by the method of observation and simulation with the help of software ARCHIPAK version 5.0. The final results of this study indicate that the design of Niang house can not provide adequate thermal comfort, especially at night until morning, where the condition of the buildings tend to underheating in considerable period of time. From the simulation can also be seen that the floor and the roof is the most critical element of the heat release.

Abstract: Implementation of cross ventilation in highrise office building will face wind speed problem due to differences in elevation and system capabilities in creating wind distribution in the room. This paper examines the influence of apertures with configured distance on building facades against wind speed and wind flow distribution. It generated by using computational fluid dynamics. Performance of cross ventilation in hipotetical models were tested using calculation model k-e RNG. Enlarge the apertures dimension up to 40% window to wall ratio increase wind velocity in building without decrease wind distribution quality. Apertures with equal distance create good distribution of wind of up to 85% depth of building.Keyword: cross ventilation, tropical, cooling effect Abstrak: Implementasi ventilasi silang di gedung kantor bertingkat akan menghadapi masalah kecepatan angin karena perbedaan ketinggian dan kemampuan sistem dalam menciptakan distribusi angin di ruangan.

Irradiation on the surface of photovoltaic module heats up the photovoltaic module itself and the room underneath the roof of integrated photovoltaic building in the tropics area. Room heating reduces thermal condition and photovoltaic module surface heating reduces its performance in generating electricity. This paper discusses an experiment of measuring the surface temperature of photovoltaic modules and fiber-cement roof surface as a comparison. This experiment also measures the impact of rising temperatures in each space underneath. It used small-scale mock-ups exposed to direct sunlight. The result of the experiment shows that photovoltaic roof surface temperature is lower than fiber-cement roof temperature. The temperature of room under photovoltaic roof is also lower than the one under fibercement roof. Empirical calculation shows that loss of electrical power found is only up to 1.7%.

Residential houses such as flats located near industrial areas are vulnerable to the threat of high-intensity dust, thereby, exposing the occupants to Sick Building Syndrome (SBS) in the form of health problems, especially in the upper respiratory system. Therefore, this research was conducted to find appropriate design solutions to minimize dust from entering buildings through the application of geometric planes as a form of defense. It is also important to note that dust is closely related to the direction of the wind which is its conveying medium. This led to the determination of the right geometric shape to be applied as a dust barrier in the building facade. Moreover, this research was based on the force-based framework which proposes a form-refine-assembly stage consisting of several methods to determine the shape through simulation and evaluation associated with existing theories. The results were able to determine the position and shape of the facade area to serve as the barrier to the arrival of dust. The design is expected to be integrated into the shape and landscape layout of buildings to reduce dust in the site area.

Direct evaporative cooling (DEC) is a passive cooling strategy adopted in predominantly hot regions to restore building thermal comfort with less energy consumption and minimum impact on the environment. The implementation and studies of DEC in tropical housing are limited. Although DEC can reduce air temperature, an increase in relative humidity can still be seen as a disadvantage. Many materials were introduced for the cooling pads, but none was explicitly proposed for use in the housing unit. The present study explores different cotton-based fabrics to be used in the proposed evaporative cooler of the public housing unit in Surabaya. It analyses its ability to reduce air temperature and identify the increase in air humidity that may occur. A small-scale model of the housing unit that incorporates an evaporative cooling system is set, and internal air temperature and humidity are recorded. Results of the analysis show that different fabric specifications can lead to various thermal performances. A cotton-based blanket is found to be suitable for the proposed strategy.

Lighting affects how people feel, react, and function in various settings, therefore lighting design strategy for worship room at churches should be aimed not only at fulfil the standard visual performance but should also be set as to enrich the room’s perception i.e. as the God’s holy place as well as a place for contemplation. Lighting problems found at the worship room of GPIB Immanuel Malang are not merely on the inappropriateness of lighting level and distributions, but also on the absence of the church’ nuance as a place for contemplation. This paper is intended to report a proposed schematic lighting design for improving the situation. Using visual hierarchical approach, the lighting design aspects such as intensity, colour rendering, type, direction and arrangement of luminaires are determined and integrated. The proposed lighting design strategy is expected to be able to solve luminous problems and create the designated room’s nuance/perceptions.

A humid tropical climate characterized by high temperatures, relative humidity and solar radiation results in uncomfortable environmental conditions. Discomfort will be worse if the building is in a dense urban area. Densely building masses often weaken the local wind speed which is necessary for evaporative cooling process in tropical climate. In addition, the narrow distance between buildings can reduce access to daylight. Both of these environmental problems were experienced by SDIT Al Uswah Surabaya, which building is located in a densely populated neighbourhood. Along with the development program of educational facilities and infrastructure at the school, improving environmental conditions with passive concept is maintained and prioritized. Embodiment of the environment with the Selective Environment approach is used in this activity. The results of this activity will be in the form of design proposals for improving ventilation and lighting in classrooms. The limitation of expanding openings becomes an obstacle in fulfilling the natural ventilation and lighting requirements. In addition, the design of a three-storey building with a single loaded corridor requires special consideration for the design of sun shading that is safe for elementary school-age children, but still supports passive lighting and ventilation.

This study examines the significant role of the floor in contact cooling, which is passive cooling that happens through direct contact with the human body. It investigates the dynamic of the relationship between floor covering materials, mats, and thermal conditions, a topic that has not been widely explored. As a starting point, this study correlates thermal conditions and the use of mats in three highrise rental flats in Surabaya. Study results show that floor temperature tends to be higher than room temperature. The average room temperature is 30.61°C, while the floor temperature reaches 32.20°C on average. The widely used underlay material is polypropylene carpet with an average thickness of 4.23±4.99 mm. In the context of a contact cooling process, floor covering materials act as both radiative and conductive cooling elements. Meanwhile, mats act as a thermal moderation whose condition can be adapted to match the occupants' behavioral patterns and preferences.Keywords: thermal condition; floor covering material; contact cooling; rental highrise unit AbstrakStudi ini mendalami peran signifikan dari lantai dalam contact cooling - pendinginan pasif yang terjadi melalui sentuhan langsung dengan tubuh manusia.
