The research discusses calibration of the method used to calculate solar heat transfer through shaded windows with continuous vertical slanted shading devices (below is abbreviated as "vertical slanted fins") with any slant angle Θ through a radiation reduction coefficient - Kbt. In order to evaluate the reduction of solar heat on window surface shaded by shading devices, a designated coefficient β of solar heat gain reduction through glazed windows should be established.

Resumo A ventilação natural é uma importante estratégia passiva para manutenção da qualidade do ar e do conforto térmico em espaços internos. O diferencial de pressão nas fachadas das edificações, quantificado a partir dos coeficientes de pressão (Cps), impacta diretamente no desempenho da ventilação natural. Fatores como direção do vento, entorno, tipo de terreno, geometria da edificação e detalhamentos nas fachadas influenciam a distribuição de pressão. Muitas investigações utilizam-se de ensaios em túneis de vento ou simulações fluidodinâmicas para avaliar os Cps em geometrias lisas e regul

Abstract:

Exterior shading devices and outdoor units can be closely coupled since these two building components are commonly installed next to each other. This study uses a coupled EnergyPlus-Fluent modeling approach to examine how a combination of exterior shading and heat rejection from outdoor units can affect the ambient outdoor environment of a building, and how changes in the ambient outdoor environment can influence cooling loads and indoor PM2.5 exposure. Three exterior shading devices were simulated, including horizontal overhangs, vertical overhangs, and vertical fins. Data from wind-tunnel ex

Abstract:

Sunlight control tools, such as shading devices, are used to improve buildings' thermal and visual conditions. One of the concerns about using shading devices is their potential to harm the visual appearance of buildings. This study aims to study the aesthetic perception of different shading devices while concurrently evaluating their energy performance. Augmented reality was used to place virtual shading devices onto a building's façade at Jordan University of Science and Technology (JUST). One hundred two students from JUST evaluated eight shading devices on a seven-step semantic differentia

Building-integrated photovoltaic (BIPV) façades are a promising technique for improving building energy performance. This study develops energy simulation models of different photovoltaic-integrated shading devices (PVSDs) in single-story and multi-story office buildings. A cross-region study in China is carried out to explore the energy performance of PVSDs in five climate zones. The shading effect of the upper PVSDs is taken into account. The results show that (1) PVSDs can be applicable in hot and cold climates; shading effects lead to a notable difference in the optimal PVSDs style. The av

In tropical urban areas, the vertical facades of buildings often play a crucial role in capturing solar radiation and heat, especially for office buildings facing west during the afternoon. In Dhaka, a tropical city, the construction of major arterial roads connecting the northern and southern regions of the city has led to the emergence of numerous commercial buildings along these roads, predominantly facing in east or west directions.

Abstract The Surabaya building sector is a prime target for energy efficiency initiatives, given its substantial contribution to overall energy consumption. Commercial buildings, often filled with glass to harness natural lighting, inadvertently raise room temperatures and increase cooling demands. Thus, ensuring thermal comfort within these structures becomes paramount. An energy use survey reveals that air conditioning accounts for a significant 62% of consumption, underscoring the need for retrofitting, especially in commercial buildings.

Abstract:

As the feature size of ULSI (ultralarge-scale integration) circuit devices shrinks, interconnects need to be scaled to maximize the wiring density and wire ability. This increased density leads to smaller contacts or via holes connecting the wires. The reduction in size increases the aspect ratio of these features for the same dielectric thickness. Conventional physical vapor deposition (PVD) techniques such as sputtering are unable to fill high aspect-ratio contacts/vias with aluminum conformally, as shown in Figure 1. This poor conformity is attributed to the shadowing effect by already-depo
