Article Citation - WoS: 1Citation - Scopus: 1Design Alternatives of Light Shelves Using Altmann Linkage(Solarlits, 2024) Atarer, Fulya; Korkmaz, Koray; Kiper, GokhanThis paper proposes a novel new light shelf design with Altmann linkage using its kinetic principles: geometry and rotational angles. As previous studies explain a light shelf's design in two ways: static and movable, the proposed one in this study has the potential to track the path of the sun due to its diagonal movement. The primary purpose is to direct the light shelf to intermediate directions, such as southeast and southwest, by utilizing the geometric properties of the Altmann linkage. The study explains how to dimension the links, calculate rotation angles, and model this device in Relux to test its daylight performance on specific dates in a year. A total of nine variations were analyzed during the three phases of design. They include shelf forms such as a rectangle, two rectangles, two squares, and varying link lengths, which define the distance to the windowsill. The final set of variations with two-square forms moving west and east successfully satisfied with sDA values as 71.52%, 72.99% (w), 75.92% (e); with ASE values as 8.83%, 8.56% (w), and 8.22% (e). This best design of Altmann linkage would be beneficial as an adaptive fa & ccedil;ade module that can direct daylight inside and achieve proper shading throughout the day and year.

Considering various perspectives, published studies focus on sustainability in architecture and the built environment, such as using daylight more effectively, enhancing energy efficiency, and designing nearly zero-energy buildings. Given the attention to sustain- ability in this domain, this review assesses the abovementioned viewpoints in buildings regarding environmental factors in relation to the micro and macro scales of the buildings and neighborhoods. Human factor has increasingly been of interest in recent works of sustainable environments. This study identifies the gaps with respect to architectural design elements considering daylighting, energy efficiency and human factors on building and neighborhood scales. A comprehensive table of the reviewed studies summarizes the aim, methodology, optimization algorithm, objective function, machine learning algorithm, digital tools, location, independent and dependent variables, view, wellness, well-being, daylight/energy performance metrics, scale, and solar strategy. The results showed that the current state-of-the-art focus on energy efficiency mainly considers passive design strategies at the building scale. Studies in the daylight domain primarily consider window properties, shading devices, and orientation. Human-centric studies showed that daylighting improves the emotional well-being of building occupants but can have negative effects such as overheating and glare. Overall findings emphasize the necessity of a holistic approach in achieving sustainability goals in dwellings at the building and neighborhood scale.Article Citation - WoS: 7Citation - Scopus: 8A Review on Adaptive and Non-Adaptive Shading Devices for Sustainable Buildings(Elsevier, 2025) Avci, Pelin; Ekici, Berk; Kazanasmaz, Zehra TugceAdaptive and non-adaptive shading devices are noteworthy fa & ccedil;ade components in designing sustainable buildings. As the comparisons of their characteristics are limited, it becomes challenging to understand their efficiency, including their impacts on occupant behavior and comfort metrics. This comprehensive review covers (a) identifying the relationship between architectural parameters and performance targets, (b) exploring model development techniques due to performance targets, and (c) declaring both energy and visual comfort metrics. The paper covers 103 papers under architectural parameters and their corresponding performance targets, namely, daylight and visual comfort metrics with lighting energy. The aim is to identify existing research trends, methodological gaps, and potential for future study by examining how performance targets affect model development approaches. The categorizations include design parameters (shading elements and fa & ccedil;ade organization), control systems (shading device control, artificial lighting control, integrated systems), performance targets (daylight metrics, visual comfort metrics, lighting energy metrics), and modeling methods (simulation, experimental, optimization). Results showed that few studies combined daylight, visual comfort, and lighting energy due to complex modeling approaches, whereas most studies dealt only with daylight. With the increase in simulation software used to conduct research results on various focuses, an increasing trend in published papers is available in this field. Studies mostly observed changes in shading device typologies, slat angles, and numbers. The most dominant climate types were humid subtropical (Cfa) and Mediterranean (Csa). Future studies can be directed to integrated performance targets and combine suitable modeling approaches with AI technologies to produce more validated and accurate results.Article Citation - WoS: 19Citation - Scopus: 21Multi-Objective Evolutionary Optimization of Photovoltaic Glass for Thermal, Daylight, and Energy Consideration(Elsevier Ltd, 2023) Taşer,A.; Kazanasmaz,T.; Kundakcı Koyunbaba,B.; Durmuş Arsan,Z.The potential of fenestration systems is increased by incorporating photovoltaic technology into windows. This recently developed technology enhances the ability to generate energy from the building façade, improve the thermal and daylight performance of buildings, and visual comfort of occupants. Integrating an evolutionary optimization algorithm into this technology is one of the possible sustainable solutions to enhance building performance and minimize environmental impact. This paper uses a genetic evolutionary optimization algorithm to explore the optimum performance of photovoltaic glass in an architecture studio regarding annual energy consumption, energy generation, and daylight performance. Design variables include a window-to-wall ratio (i.e., window size and location) and amorphous-silicon thin-film solar cell transparency to generate optimum Pareto-front solutions for the case building. Optimization objectives are minimizing annual thermal (i.e., heating and cooling) loads and maximizing Spatial Daylight Autonomy. Optimized results of low-E semi-transparent amorphous-silicon photovoltaic glass applied on the façade show that the spatial daylight autonomy is increased to 82% with reduced glare risk and higher visual comfort for the occupants. Photovoltaic glass helped reduce the selected room's seasonal and annual lighting loads by up to 26.7%. Lastly, compared to non-optimized photovoltaic glass, they provide 23.2% more annual electrical energy. © 2023 International Solar Energy Society
