The use of daylight in educational settings has a significant impact on the well-being attention and academic achievement of students. However providing adequate daylighting without glare can be difficult especially in deep-plan layout classrooms because daylight is not constant and its strength varies with distance from the facade necessitating the use of additional solutions frequently. In this study tubular daylight guidance systems (TDGS) and movable shading devices are proposed to increase daylight availability in the Yasar University Faculty of Architecture Temporary Studio which has a deep plan layout and receives daylight only from the southeast facade. The objective was to meet the LEED daylight evaluation requirements for each zone which require sDA to be at least 55% and ASE to be at most 10% in the selected analysis area. To propose TDGS and movable shadings with the most efficient angles and positions, Rhinoceros Grasshopper and Climate Studio were used and simulation results were validated by real -time measurements. The design proposal simulation results achieved a significant increase in daylight availability in the rear part of the room (zone 2-3) while glare was diminished near the facade (zone1). The proposed design strategy improved daylight availability through the room demonstrating that the systems perform well together.
Daylight Enhancement Strategies for Historic Buildings: A Critical Review of Interventions, Their Constraints, and Applicability
(SolarLits, 2026) Cilasun Kunduraci, Arzu; Sonmez, Nurefsan; Kunduraci, Arzu Cilasun
With the growing urgency to reduce carbon emissions in the built environment, enhancing daylight availability in historic buildings has become a critical and challenging task due to the required balance between environmental sustainability objectives and cultural heritage conservation principles. This paper presents a systematic and critical review of 54 studies focusing on daylight enhancement strategies in historic buildings, published between 2000 and 2025. Following the PRISMA scoping review method, this review investigates intervention challenges according to three primary constraints: regulatory and conservation limitations, material and structural constraints, and climate-responsive requirements. By mapping currently employed daylighting techniques in historic buildings and critically assessing their underlying assumptions, this study aims to bridge the gap between performancedriven daylighting research and cultural heritage preservation principles. The findings are intended to promote multidisciplinary discourse and serve as a basis for creating contextually acceptable, ethically responsible, and technically feasible daylighting recommendations for historic buildings.

Examining occupancy and architectural aspects affecting manual lighting control behaviour in offices based on a user survey
(LLC Editorial of Journal "Light Technik" lights-nr@inbox.ru VNISI rooms 327334106 Prospect Mira Moscow 129626, 2018) Arzu Cilasun Kunduraci; Tugce Kazanasmaz; Truus Hordijk; Cilasun Kunduraci, Arzu; Kazanasmaz, Tuğçe; Hordijk, Truus
Further understanding the building occupants’ needs and behaviors can reduce lighting energy consumption. This research explores how the occupancy and interior architectural aspects become effective in manual lighting control in offices. It involves a multiple sectioned questionnaire focusing on the possible architectural factors such as the desk position the surface colours the distance to window the distance between desk and lighting switch and inquiring participants’ manual lighting control behaviour through the photographs of modified interior layouts surface colours and time intervals. Statistical methods are used to determine the significant aspects which may reduce the use of lighting control. Interior layout distance to window time of the day and number of occupants in the offices are the most significant contributions to the manual lighting control behaviour. To pay attention in these contributions it would be possible to reduce the use of electricity for lighting while user satisfaction increases. © 2018 Elsevier B.V. All rights reserved.

Indoor Environmental Quality Optimisation Model for Institutional Care Rooms of Elderly People
(MDPI, 2023) Cemre Cubukcuoglu; Arzu Cilasun Kunduraci; Sahar Asadollahi Asl Zarkhah; Zarkhah, Sahar Asadollahi Asl; Cubukcuoglu, Cemre; Cilasun Kunduraci, Arzu; Asadollahi Asl Zarkhah, Sahar; Kunduraci, Arzu Cilasun
It is known that the elderly usually spend the last years of their lives indoors with little contact with others and the outside environment. Indoor environmental quality (IEQ) conditions related to lighting air quality thermal comfort and acoustics directly affect their quality of life. In this study the main focus is on the design of institutional care rooms for elderly people to create an indoor comfort. However considering all four factors of IEQ in one model is a challenging task. A multi-objective problem is formulated based on a weighted sum of IEQ components in a parametric modelling environment using computational design methods. Several simulation tools are utilised and a Self-Adaptive Ensemble Differential Evolution Algorithm is proposed to tackle this complex problem. The results show that optimal ranges for each IEQ component are achieved with average values reaching 72% of the ideal benchmarks after the algorithm is converged. Results reveal strong correlations between IEQ components. This significant improvement in indoor environmental quality (IEQ) demonstrates the efficacy of the optimisation algorithm used. This study emphasises the flexibility and relevance of these findings for wider implementation in similar settings.
