(LLC Editorial of Journal ""Light Technik"", 2024) Nurefsan Sönmez; Arzu Cilasun Kunduraci; Kunduraci, Cilasun; Sonmez, Nurefsan; Kunduraci, Arzu Cilasun
Daylight is essential for enhancing visual comfort but poses risks to museum artefacts due to heat UV radiation and light fluctuations. Careful management of daylight penetration in museums may involve blocking or directing openings which could mean that the displays’ illumination must either entirely or partially rely on electrical lighting. Implementing such architectural changes in heritage buildings for museums requires more careful consideration and balancing architectural integrity with improving lighting conditions. An assessment of the lighting design of the Ataturk Museum housed in a historic building in Izmir Turkey originally a mansion built in 1875 is presented in this study. The primary objective is to analyse the architectural lighting design focusing on visual quality and artefact conservation particularly Ataturk’s personal belongings. This study attempts to report and assess electrical and daylight usage provides suggestions for demanding display areas from a visitor’s perspective through on-site evaluations and aims to record this culturally and architecturally significant building for future researchers. © 2024 Elsevier B.V.

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.

Energy Saving Opportunities through Glazing and Shading Alternatives
(KONYA TECHNICAL UNIV FAC ARCHITECTURE & DESIGN, 2022) Arzu Cilasun Kunduraci; Sueleyman Ivgin; Ivgin, Sueleyman; Kunduraci, Arzu Cilasun
Windows are the weakest elements due to their high heat transfer coefficient and are responsible for 60% energy heat/gain loss. Healthcare buildings are one of the biggest consumers of energy due to continuous occupation hours and medical requirements providing comfortable conditions for people in need of care and staff, yet recently less attention was given to healthcare buildings due to their unique operational requirements and advanced medical equipment. Thus the main purpose of this study was to evaluate energy saving potentials of windows through glazing and shading alternatives over a case study. Within this study a single patient room in Izmir Turkey has been chosen as a case study and the room was simulated for sixteen scenarios generated by using four different glazing and shading systems. Each design scenario was simulated using DALEC for their lighting heating cooling and total energy consumption. Results showed that lighting energy consumption constitutes the highest energy demand (up to 52%) and high transmitting glazing usage can reduce lighting loads. Finally up to 16.3% energy saving is possible only by changing shading and glazing types. Though there is a great diversity of glazing and shading types this study's outputs only reflect the selected four glazing and four shading system types that are offered by DALEC. Healthcare buildings spend a vast amount of energy to provide thermal and visual comfort for various user profiles. Considering the large number of patient rooms in healthcare facilities only careful consideration of glazing or shadings can significantly contribute to energy savings. This study focuses on shading and glazing alternatives as an energy-saving strategy. For simulation an underrecognized BES tool DALEC was hyped to show integrated thermal and visual energy consumption. The findings highlight that energy savings of up to 16.3% is possible.

ENHANCING DAYLIGHT AVAILABILITY IN HISTORICAL BUILDINGS THROUGH TUBULAR DAYLIGHT GUIDANCE SYSTEMS: A SIMULATION-BASED STUDY
(LLC Editorial of Journal ""Light Technik"", 2023) Nurefsan Sönmez; Arzu Cilasun Kunduraci; Sonmez, Nurefsan; Kunduraci, Arzu Cilasun
This simulation-based study investigates the potential of tubular daylight guidance systems (TDGS) to enhance daylight availability in historical build-ings. Historical buildings often face challenges in providing sufficient daylight to non-lit areas without altering the building’s facade. TDGS offer a pas-sive building-integrated solution that redirects daylight to target areas while preserving the building’s originality. The study focuses on a historic passage building without ground floor openings and aims to improve visual comfort and daylight availabil-ity. Climate Studio software is used to assess the current daylighting conditions and to simulate vari-ous scenarios for TDGS implementation. The study considers four TDGS alternatives with different di-ameters evaluating their impact on useful daylight illuminance (UDI) and spatial daylight autonomy (sDA). The findings reveal significant increases in UDI and sDA ranging from 68.7 % to 403.7 % and from 79.9 % to 1813.6 % respectively depending on the tube diameter. These results underscore the importance of daylight tube diameter in increasing the availability and distribution of useful daylight. The study emphasizes the potential of TDGS to op-timize daylighting experiences in historical buildings with limited daylight. © 2024 Elsevier B.V. All rights reserved.

Fuzzy logic model for the categorization of manual lighting control behaviour patterns based on daylight illuminance and interior layout
(SAGE Publications Ltd info@sagepub.co.uk, 2019) Arzu Cilasun Kunduraci; Tugce Kazanasmaz; Cılasun Kunduracı, Arzu; Kunduraci, Arzu Cilasun; Kazanasmaz, Z. Tugce
In considering total building energy consumption lighting plays an important role in shaping energy consumption and use. Although key strategies (such as energy efficient lighting products lighting control systems and energy simulation software) are developed so far such attempts may be unsuccessful unless users are not taken into consideration. Users’ behaviours and their manual lighting control actions depend on various factors though within the scope of this study manual lighting control behaviour was analysed only in terms of interior layout and daylight illuminance. Three private offices in Izmir Institute of Technology were monitored using illuminance metres and occupancy/light detectors under eight different interior layout conditions. In relation to change of interior layout and daylight penetrations users’ manual lighting control behaviours were monitored. The obtained data were then used to construct a fuzzy logic model in MATLAB FIS editor. A fuzzy logic algorithm was applied to classify behaviour patterns about the tendency to turn on the lights. This kind of prediction of the light usage tendency regarding the occupancy is aimed to foresee the ‘possible’ manual lighting control behaviour within given conditions. The gathered classification can be used further in future studies of manual lighting control behaviour and energy-saving estimations/simulations. © 2019 Elsevier B.V. All rights reserved.

(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.

To Look or Not To Look: Reading User Behavior in the Spatial Atmosphere of the City Skyline of Izmir
(University of Minnesota Press, 2024) İlke Hiçsönmezler; Arzu Cilasun Kunduraci; Ahenk Yılmaz; Yilmaz, Ahenk; Kunduraci, Arzu Cilasun; Hiçsönmezler, İlke
This study focuses on the effects of spatial qualities of the viewing location on the behavior of citizens towards the observation of the skylines. The majority of the existing literature on skyline studies revolves around the discussions of the aesthetic qualities of the skyline per se and ignores the observation space. Nevertheless the differences in citizens' behavior towards viewing the skyline stem not only from their diverse personal characteristics and daily emotional states but also from the spatial qualities of the viewing space. This study addresses this gap in the literature with its concentration on the qualities of the urban spaces from which the city skyline is viewed. The objective of this study therefore is to fill this gap by discussing the ultimate behavioral decisions of experiencers in viewing the Izmir skyline from the perspective of the spatial characteristics of the Karşıyaka coastline as an observation location. In doing so the study first focuses on the atmosphere theories where the reciprocal relationship between the qualities of experienced space and its experiencers become dominant. Through observations in the Karşıyaka coastline the reciprocal relationship leads to the definition of the spatial factors as layers of analysis which are based on the transformation of the spatial layers of the experienced space and the behavioral decisions of the experiencers. Then to better comprehend their relationships Analytical Hierarchy Process (AHP) is utilized to analyze the observational data. The study by merging the spatial atmosphere and contemplative neuroaesthetic theories provides a new framework for the upcoming skyline-based studies. Moreover the outcomes of the analysis demonstrate that the contrast between day and night city skyline viewing in the Karşıyaka coastline emerges as a point of reference for lighting proving to be the most impactful factor among all layers. © 2025 Elsevier B.V.
