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.

“…However, for other cases, using proper shading device is essential to prevent overheating in the summer. In case of using a shading device (especially a movable shading device), energy consumption will be minimal even if large glass areas are used [9].…”

“…In addition, for using daylight, the window area should not be less than 10% of the floor area, although the optimum window size for daylight may not be the same as the optimum value for energy [19]. To determine the optimum WWR for a particular building, the characteristics of the environment and the urban topology should also be considered [9]. The location and window shape are also issues that should be investigated in future studies [14].…”

The Optimum Window-to-Wall Ratio in Office Buildings for Hot‒Humid, Hot‒Dry, and Cold Climates in Iran

et al. 2019

About half of the energy loss in buildings is wasted through windows. Determining the optimum window-to-wall ratio (WWR) for different building facades would reduce such energy losses. The optimum WWR is the window area that minimizes the total annual energy of cooling, heating, and lighting. The purpose of this study is to investigate the optimum WWR of different facades of an office building. For this purpose, a sample building is simulated by means of DesignBuilder software in order to investigate the annual solar heat gain, cooling load, heating load, and lighting consumption for the three cities of Bushehr, Shiraz, and Tabriz, and optimum window areas of office buildings for the three cities are determined. Based on the results, the optimum window area for the north building facade for all climates is 20–30%. This amount for the southern facade of the building in Bushehr, Shiraz, and Tabriz is, respectively, 20–30%, 10–30%, and 20–50%. The optimum window area for the eastern and western building facades in Bushehr is 30–50%; in Tabriz it is 40–70%, and in Shiraz it is 20–60% and 40–70%, respectively. The difference between the maximum and minimum energy consumption with different window areas in Bushehr and Shiraz is 20–100% and in Tabriz it is 16–25%.

“…E. Ghisi and J. Tinker [38] minimized energy consumption by capturing the best window area using digital analysis techniques. M. Košira et al [39] defined five simplified baseline models in central European climate conditions. The best energy-saving solution was found by dynamically searching the building's window area and azimuth.…”

“…As described in the previous section, only a small number of studies have developed a detailed scheme design and conducted experimental or field investigations, but it does not mean that the value and contribution of those theoretical studies can be easily denied. In a recent analysis, building orientation was considered one of the key optimization variables in the early design phase [39,57,61,64,67]. Optimal orientation can effectively reduce the negative effects of solar radiation, thereby correspondingly reducing the use of heating or cooling energy.…”

As most countries have widespread and growing concerns about the sustainable development of society, the requirement to continuously reduce energy consumption poses challenges for the architecture, engineering and construction (AEC) industry. Performance-oriented architectural design and optimization, as a novel design philosophy and comprehensive evolution technology, has been accepted by architects, engineers, and stakeholders for a period of time. Performance in the context of architecture is a widely discussed definition that has long shown a correlation with visual and cultural attributes. Shifting the paradigm of sustainable development while ensuring that the function and aesthetics of the building are not overlooked has been the focus of public attention. Considering the core design elements that affect energy conservation and style performance, the design and optimization of building envelopes, form, and shading systems were selected as research materials. From the perspective of epistemology and methodology, a systematic review of 99 papers was conducted to promulgate the latest development status of energy-efficiency design. This paper manifests a detailed analysis of the design patterns, research features, optimization objectives, and techniques of current approaches. The review found that performance-oriented design optimization can benefit the entire industry from the heuristic knowledge base and the expansion of the design space while maintaining sustainability. In contrast, challenges such as tools, skills, collaboration frameworks, and calibration models are highlighted.
