EXAMINING THE DAYLIGHTING PERFORMANCE OF OFFICE BUILDINGS ON THE EXAMPLE OF THE RECTORATE BUILDING IN IZMIR
(ZNACK PUBLISHING HOUSE, 2021) Ecenur Kizilorenli; Ebru Alakavuk; Alakavuk, Ebru; Kizilorenli, Ecenur
The efficient use of energy resources has affected all areas of life as well as architecture. There are many ways to increase energy efficiency in buildings. Supporting the efficient use of daylight in the design process reducing the energy to be used for artificial illumination and reducing heating costs are among the applications that support energy efficiency. The issue of supporting daylighting by reducing artificial illumination draws attention especially in office buildings due to the high number of hours used during the day. Insufficient light and lack of visual comfort in offices used during the day increase the consumption of electrical energy. Within the scope of this study a parametric study was conducted to optimize the daylighting performance of an office building. For this purpose rectorate building of a university which is used as an office building was selected for the case study and the daylight condition of this building was examined. For increasing the daylighting performance of the building some revisions were proposed. Results of this research are discussed with visuals and simulation values.

Construction courses are fundamental to architectural education and prototyping is an effective way to engage students in hands-on learning and one of the most effective methods for teaching practical skills. Furthermore these courses must incorporate digital technologies as current professional trends increasingly demand their use. But how can we integrate these elements into lecture-based courses that are constrained by limited time and resources? This paper describes the design fabrication and assembly of a free-form gridshell structure as part of an undergraduate course at the Faculty of Architecture Ya & scedil,ar University. The prototype was constructed using a hybrid fabrication technique that combines timber battens with 3D-printed connections facilitating both assembly and potential disassembly. Over the course of 14 weeks students developed the structure through an iterative design-build process gaining a unique hands-on learning experience in experimental construction. The paper highlights how the development of the structure proceeded deliberately with reflections on failures between iterations. This approach not only facilitated learning but also led to relevant research findings. The final prototype serves as a proof of concept for the advantages of hybrid fabrication making it suitable for temporary structures within architectural and engineering curricula. The insights gained from this practical experience can contribute to both structural engineering and architectural education by providing valuable knowledge on digital production and structural design processes. Additionally the study contributes to the ongoing discussion about the performance of 3D-printed nodes under challenging structural conditions highlighting both the potential and the limitations of this emerging technology.

Multi-Objective Optimization of a Folding Kinetic Facade System Proposal for Thermal Daylight and Energy Performances
(Gazi Universitesi, 2025) Yonca Yaman; Ecenur Kızılörenli; Ayça Tokuç; Kizilorenli, Ecenur; Yaman, Yonca; Tokuc, Ayca
Efficient utilization of daylight and energy resources significantly influences the quality of indoor spaces user comfort and overall efficiency. This study presents a folding facade proposal through the design alternatives offered by kinetic architecture and parametric design to enhance efficiency. This alternative design method integrates and coordinates the design components simultaneously and makes any intervention easier when compared with traditional design methods. In this context the method is based on computational models aiming to find the most efficient design alternative by optimization. The proposed facade design specifically targets an indoor office space within a university. The modular system integrated into existing windows facilitates a folding movement. This dynamic feature aims to optimize illumination within the space effectively controlling daylight without causing disruptions to users. Simultaneously the design seeks to balance energy consumption and ensure thermal comfort. The results show that it provides a significant improvement over the base case. The proposed kinetic façade system improved indoor thermal comfort by 80.68-98.11% while slightly increasing energy use (4.72% at most). The average improvement in Spatial Daylight Autonomy (sDA) is 34.98%. Although the number of solutions meeting LEED in terms of Annual Solar Exposure (ASE) is small there is an average improvement of up to 64% compared to the base case. In conclusion the proposed kinetic facade system proves to be a valuable intervention for enhancing the indoor environment of an office space at Dokuz Eylül University. © 2025 Elsevier B.V.

User-Oriented Architectural Design of Separated Infill Walls to Prevent Soft Ground Story in Reinforced Concrete Low-Rise Buildings
(ASCE-AMER SOC CIVIL ENGINEERS, 2021) Mauricio Morales-Beltran; Feyza Durmuslar; Ecenur Kizilorenli; Morales-Beltran, Mauricio; Kizilorenli, Ecenur; Klzllörenli, Ecenur; Durmuslar, Feyza
Buildings with open ground stories are more vulnerable to soft story mechanisms which might lead to building collapse in a moderate quake. To mitigate these negative effects retrofitting techniques typically introduce new structural elements or energy dissipation devices which increases the deformation capacity of the soft story without modifying the stories above. However by altering the open nature of the ground floor these solutions fail to integrate the occupants' preferences and needs into the design process. Therefore instead of modifying the ground floor this study will propose a user-centered design process which is based on separated infill walls in the upper stories to mitigate the effects of soft story irregularity. The user-centered design strategy integrates the needs and preferences of the occupants into the design solutions of their built environment. To achieve this two low-rise reinforced concrete buildings in Turkey were selected as case studies and subjected to structural analyses to determine whether the separation of the existing infill masonry walls reduced the lateral strength of the structure. In parallel preliminary designs of the infill separations was developed and discussed with architects practicing engineers and builders. The feedback helped to develop design details to achieve the separation of the infill walls from the frames in the studied buildings. The occupants that live in the existing buildings or the surrounding areas were interviewed and presented with parametric variations of these proposals. Quantitative data suggests that separation of the infill walls is a feasible solution that could be applied to new construction and for existing reinforced concrete multistory buildings and the qualitative data that was obtained from the interviews suggested that user-centered design approaches help to develop suitable seismic mitigation strategies.
