🔺 Performance Analysis of External Shading Devices
@Reference_Energy
📌 Building and Environment, Vol. 22, No. 4, pp. 269-284, 1987
@Reference_Energy
🔺 ABSTRACT
The performance of the basic vertical and horizontal types of external shading devices was studied in detail. The different performance modes are presented in the form of shading masks featured
by the cutoff angles.
Mathematical formulae were derived to express the cutoff angles in terms of the various geometrical parameters characterizing the combination of the shading device and the fenestration. These angles define the partial and complete shading phases. The formulae are put in generalized forms, in terms of normalized geometrical ratios, so as to be independent of the absolute dimensions. A unified approach was followed for both vertical and horizontal devices so that the derived normalized expressions can be adopted for the two types.
The effect of the various geometrical factors on the cutoff angles, i.e. on the form of the shading mask, was investigated for different configurations of vertical and horizontal shades. Based on the derived relations, the trends of variation, of the cutoff angles with these factors, are graphically presented for each case.

📌 The Analysis of Daylight Factor and Illumination in Iranian Traditional Architecture
Case Studies: Qajar Era Houses, Qazvin, Iran
@Reference_Energy
🔺 ABSTRACT
As buildings are the biggest consumers of energy, reducing the total energy consumption in this area may have a significant role in preserving non-renewable resources. Appropriate use of daylight may decrease the need for electric lighting which may lead to reduced energy consumption and costs in lighting. Moreover, in the Iranian traditional architecture, there have been various passive strategies to take advantage of the renewable resources to provide thermal and visual comfort for users. Using daylight is one of these methods and strategies. The present study aims at analyzing the lighting condition of these buildings. Therefore, four buildings in Qazvin city, which belong to Qajar period (1785-7925 A.D.), were selected as the case studies. Then, the elected buildings were simulated as three-dimensional models. Finally, the analysis of daylight factor and illuminance was conducted using Ecotect Analysis, Energy Plus and VELUX Daylight Visualizer Software. After the analysis of data obtained from the respective simulations and their comparison with the extant standards of lighting, it was found that the average daylight factor at all under-scrutiny rooms was acceptable; in addition, 76 percent of rooms required no artificial light during the daytime. The reason for appropriate lighting in these spaces is positioning alongside the sunlit side of the building as well as use of big windows. In addition, the analysis of illuminance shows that the distribution of light in interior spaces is even. Moreover, although much amount of light enters the space, the use of light color prevents contrast and daze while enhances visual comfort.

📌 Investigation of the relationship between depth of overhang and amount of daylight indicators in office buildings of Kerman city
@Reference_Energy
🔺 ABSTRACT
🔸 Background: The use of daylight in offices has become an effective strategy to improve the quality of indoor space and energy efficiency. There is enough potential to have daylight autonomy in Kerman as a city with more than 300 sunny days a year. Therefore, this study aimed to investigate the relationship between facades configuration and the amount of daylight in office buildings of Kerman.
🔸 Methods: This study was carried out based on the simulation in DesignBuilder software (DBS). In this study, 36 typical rooms, with the same physical characteristics (4 m×6 m×4 m), with window-to-wall ratio (WWR) between 10- 90% with four overhang depths (0, 0.5, 1 and 1.5 m) were modeled.
🔸 Results: Based on daylight utilization, the results indicate that an optimal WWR for a room with 1 m overhang depth ranged from 50% to 70%. Also, the room with 0.5 m overhang depth and without overhang, had suitable daylight while WWR was at least 50%, but the room with 1.5 m depth would not encounter glare problem even when WWR was 90%.
🔸 Conclusion: The results confirm that overhang depth and WWR have significant effect on daylight parameters such as daylight factor (DF), work plane illuminance (WPI), and WPI ratio. Hence, these insights can be useful for designers to design buildings with lower energy use and higher daylight quality, when enough light is provided in office rooms.
