“…The building function studied in this study is one of the faculty buildings. It is similar to an office building, in which thermal transfer mostly comes from the radiation component [58]. Thus it is in line with previous research [26].…”

The building envelope’s overall thermal transfer value (OTTV) is an essential aspect of creating sustainable and energy-saving architecture. The original OTTV formula makes it difficult for any user who is not an expert to calculate OTTV. Designers usually need an empirical formula to determine the design direction in the initial design stage. Instead of replacing the previous SNI (The Indonesian National Standard) 6389:2011, this paper will introduce several simple equations as empirical formulas covering solar factor (SF), effective shading coefficient (SCeff), and OTTV. Three hundred architraves units of facade models were investigated to make the formulas or equations. Regression analysis was used to make three practical formulas in this paper. The research validation consists of first and crossed-validation to determine the Root Mean Square Error (RMSE) and Average Percentage of Error (APE) between the rule of thumb and original equation of OTTV from the Indonesian standard. The results show that the RMSE is only 1.12 W/m2, while the APE is 1.05%. By these results, the empirical formulas can be implemented to be the rules of thumb in the first stage of the design process because the values of RMSE and APE are still under the design margin of thermal design in the building.

“…The two points observed are the point in front of the inlet (in front of the upper window, 2.5m p-ISSN: 1410-2331 e-ISSN: 2460-1217 above floor) and the working space point (0.75 m above the floor). These two points are a reference to thermal comfort based on wind velocity in space [16,17]. Figure 3 described the wind velocity contour from model 1A.…”

The abundance of solar light in tropical countries is the advantage of the utilization of solar energy. Increasingly expensive electricity forces buildings to use passive ventilation as building coolers. One of them is the use of the stack effect through the solar chimney. The absence of residential buildings that use the solar chimney as part of a passive ventilation system makes the need for prototypes for residential buildings. The application of solar chimney to homes in Jakarta is something new. Six types of the solar chimney have been tested on a prototype, one-story residential houses in Jakarta. The location was assumed to be in the densely populated area of South Jakarta. Wind velocity ambient data using Rubber locations. Using Ansys 16.0, simulations have been carried out, and solar chimney with double-full roof collector was able to induce a wind velocity of 0.41 m/s on average

“…Building envelopes such as walls, roofs, windows and floors isolate the indoor environment from the outside weather conditions to maintain indoor thermal comfort [8]. Therefore, building envelopes present an opportunity to enhance indoor thermal comfort and reduce energy consumption by influencing the heating and cooling loads of a building [9]. Many steps have been taken by Heat, ventilation and air condition (HVAC) engineers, such as incorporating facades, hydronic systems, thermal conditioning by radiation, thermal storage devices and many more to reduce energy consumption in buildings [10].…”

Tropical region such as Darwin has similar weather patterns throughout the year, thus creating higher energy demands in residential buildings. Typically, buildings consume about 40 per cent of the total energy consumption for indoor heating and cooling. Therefore, building envelopes are linked with design strategies such as the use of thermal energy storage and phase change materials (PCM) to minimize this energy consumption by storing a large amount of thermal energy. Primarily, PCMs are targeted by researchers for use in different components of buildings for thermal efficiency; thus, this study aimed to provide a suitable PCM to optimize indoor thermal comfort and minimize the cooling loads of residential buildings in tropical climates through simulation of a tropical climate building and provide optimum thickness for the selected material. Microencapsulated PCM mixed with gypsum in wallboards were used to reduce the cooling load of a building located in Darwin. The cooling load of the building was calculated using Revit software. A comparison of the cooling load of the building was carried out using PCM-incorporated wallboards of thicknesses of 0 cm, 1 cm and 2 cm in Energy Plus software. The total cooling load decreased by 1.1% when the 1-centimetre-thickness was applied to the wall, whereas a 1.5% reduction was obtained when a 2-centimetre-thick PCM layer was applied. Furthermore, the reduced cooling loads due to impregnation of the PCM-based gypsum wallboard gave reduced energy consumption. Ultimately, the 2-centimetre-thickness PCM-based gypsum wallboard gave a maximum reduction in cooling load with a 7.6% reduction in total site energy and 4.76% energy saving in USD/m2/year.
