“…Table 2 and 3 show that the horizontal shade is perfect in giving shade for north, North-East, East, South-East and South. It confirms the result of the other study that horizontal shading performs well to give a shade (Kim et al 2017). On this orientation, the horizontal shade is able to provide shade on the peak hours of high radiation of the sun.…”

“…In relation to this matter, sun path diagram would help the architect to design the window and shading, which will perform optimal shading design as well as excellent daylighting without excessive heat (Lippsmier 1997;Ardiyanto, Hamid, and Sutopo 2019). A window with too large depth of shading will reject the heat, but in the same time it will use large of lighting energy (Kim et al 2017). Sun path diagram can determine the horizontal and vertical shadow angles for any specific times.…”

Sun orientation plays a significant role in architectural design. Concerning this, the sun-path diagram is a tool for developing more knowledge to improve the quality of building design. For achieving good and thermally comfortable building design, the sun shading device is essential to work. Therefore, this study performs an evaluation of the shading device in tropics utilising the sun-path diagram. This study evaluates the horizontal, vertical and louvre shadings on eight wind directions in Banda Aceh as a case study in tropics by adopting shadow angle protractor for superimposing the vertical (VSA) and horizontal shading angle (HSA) on the stereographic sun-path diagram to indicate the shadow and daylighting time. The result of this study proposes the suitable type of shading and the acceptable depth of horizontal shading dimensions for all of the orientations of the wind directions.

Traditional buildings in Malaysia were developed for hundreds of years to respond to the local climate. Occupants can comfortably occupy the traditional buildings without a mechanical system such as an air conditioning system. However, in many modern buildings, whether houses, mosques or shophouses, similar traditional strategies are not extensively adopted; thus, they are very dependent on the mechanical system to achieve good thermal comfort. Therefore, this study aims to investigate the effect of selected passive cooling strategies on the indoor temperature of a building in a tropical climate. The methodology adopted in this study was computer simulation validated with measured data from a selected case study. The thermal comfort of a case study was examined with different passive cooling strategies that were applied using IES-VE 2019 building simulation software. The simulation was conducted for various design strategies, such as adding shading devices and closing the curtains to decrease the amount of solar radiation that enters the house from the windows, using timber for walls and clay tiles for the roofs and examining seven different orientations to find the best strategy for the house. All these strategies were tested and compared between full-day natural ventilation and without any ventilation. The thermal comfort of these strategies was graphically defined based on the operative temperature. The results of this study revealed that protecting the windows from solar radiation by adding shading devices and closing the curtains had the lowest indoor operative temperature achievement compared to other examined strategies.

“…On the other hand, natural light can be excessive during noon hours and in summer, as to disturb vision and generate unwanted solar heat gains (Byrd, 2012). The latter makes it very important to correctly balance and design different elements, such as interiors, facade layouts, windows and shading devices to obtain the needed illumination and minimize energy consumption (De Luca et al , 2016; Haase and Grynning, 2017; Kim et al , 2016; Darula et al , 2015).…”

Purpose Electric lighting accounts for a large share of energy consumption in commercial buildings. Utilization of daylight can significantly help to reduce the need for artificial lighting, increase workers productivity, customers’ satisfaction and consequently improve sales. However, excessive use of glazing and absence of lighting controls can contribute greatly to higher energy need for heating and cooling and cause undesired glare effects. Thus, optimizing the size, position and materials of external glazing, with the addition of deflectors and dynamic artificial lighting, can become key aspects in the design of sustainable low energy buildings. The purpose of this paper is to analyze daylight potential and energy performance of a hall-type commercial building, situated in the cold climate of Finland, by utilizing different combinations of skylights, windows and lighting controls. Design/methodology/approach The authors have used computer simulations to estimate daylight and energy performance of a single floor commercial building in relation to various combinations of skylights and windows with variable glazing materials, light deflectors and zonal lighting controls. Findings The results show that electric light energy saving potential ranges from a negligible 1.9 percent to a significant 58.6 percent in the case of glass skylights and wall windows using multi-zone lighting control. Total delivered energy ranges between increase of 1.5 and 21.2 percent in the cases with single zone lighting control and between decrease of 4.5 percent and increase of 4.5 percent in the cases with multi-zone control. The highest decrease in primary energy consumption was 2.2 percent for single zone and 17.6 percent for multi-zone lighting control. The research underlines the significant potential of electric light energy savings using daylighting strategies that, including the control of direct solar access for glare and internal gains, can be more than 50 percent. Originality/value This research combines accurate daylight and energy assessment for commercial hall buildings based in cold climate region with multiple design variations. The novelty of this work is the consideration of interior elements, shelves and deflectors, in the calculations. This is made possible through the combined use of validated simulation platforms for detailed annual daylighting and electric lighting calculation (Radiance and Daysim) and energy analysis (IDA-ICE, Equa Simulation AB). This method allows to obtain a reliable assessment of the potential of using natural light sources in buildings.
