    Evaluation of Window Design and Daylight Performance of Main Room in Kula Houses
    (Izmir Institute of Technology, 2020) Battal, Cansu; İpekoğlu, Başak; Kazanasmaz, Tuğçe
    When developing restoration decisions for conservation of historic houses, determination of daylight performance of the spaces is important for new usage proposals. Among the rooms located around sofa in Anatolian historical houses, main room is the most spectacular space. It should have sufficient and homogeneously distributed daylight in restored houses. This study aims to examine daylight performance of main room and preserve original lighting features in restoration and re-functioning decisions. For this purpose, Kaçıklar, Zabunlar, Kestaneciler and Zühtü Bey Houses, were selected as examples for the research. Daylight performance measurements were taken in main rooms in all seasons, in the morning, at noon, in late afternoon using an illuminance meter. As a result of the study, it was determined that illumination was not sufficient for all seasons in unrestored Kaçıklar House, sufficient for all seasons in unrestored Zabunlar House, in restored Kestaneciler House, also sufficient in restored Zühtü Bey House in autumn whereas insufficient in other seasons. In Kaçıklar House, opening the window that was closed, cleaning the paint on top windows, selecting a light-coloured wall finish material will positively affect lighting values. In restored Zühtü Bey House, the window, converted into a built-in cupboard, and the closed top window to be restored to original state and cleaning of improper paint on the top windows on the south wall will affect the lighting level positively. This study is important in terms of determining specific daylight illumination properties of historical houses and underlines the improvement of repair and conservation decisions.

    User Lighting Preferences in Museums and Galleries: Virtual Models and a Survey for Multiple Exhibition and Lighting Conditions
    (Izmir Institute of Technology, 2019) Çevik, Aslıhan; Kazanasmaz, Tuğçe
    Just as any other interior, lighting quality of exhibition spaces need to be examined to enhance visual quality and comfort. Exhibition lighting is already a chaotic process with many quantitative and qualitative parameters, their relation with each other and concerns of multi-disciplines. Consequently, the impacts and the potentials of subjective appreciation, daylight, user perception and behavior, new developments and the relation between the parameters are often disregarded. In this thesis, a comprehensive study is conducted to understand the impact of lighting type, color temperature, room and exhibition parameters on navigation and impressions. A set of three exhibition spaces with various room and lighting conditions were modelled virtually, to be evaluated in a three-part questionnaire. A total of 90 participants are selected equally from three profession groups which are architects, visitors and artists. Their movement through the exhibition, preferences and impressions are analyzed with various statistical analysis methods. Results show that there are some distinctive preferences between occupation groups. In the first part, it can be seen that navigation choices changes with the lighting type as the movement towards daylight increases in transition areas and the end. Generally, daylight is preferred for sculpture while artificial light is preferred for paintings. In the second and third part, it was found out that lighting type is the major factor against color temperature in preference and impressions. The best setting is picked as single spotlight with neutral color temperature. Warm ambient lighting is not received well. Ultimately, lighting preferences and perception change with different room and exhibition conditions.

    Double-Skin Facade Options for Optimum Daylight Quality: an Office Case in Izmir
    (Izmir Institute of Technology, 2019) Ergin, Meltem; Kazanasmaz, Tuğçe
    DSF buildings have been designed and used mainly for the purposes of improving human comfort and decreasing energy consumption in new and renovated structures. However, there has been scarce studies in literature concerning daylighting in DSF buildings in comparison to thermal and ventilation systems. Actually, lighting is responsible for %30 to %40 of all the energy utilized in office buildings. This value is remarkable to take into consideration the daylight efficiency of DSF building at the design phase. This study examines the effect of double-skin facades system variables on daylight performance. In accordance with this purpose, an office in Izmir Institute of Technology (Iztech) has been selected and primarily, it has been tested to measure the reliability of the daylight simulation software (Relux) to be used. Later, the effect of the second skin on daylight performance has been analyzed by comparing single skin glass curtain wall and double skin facade simulations. Various components generally used in the double-skin facades have been detected and their effects on daylight level have been studied. These components are glass types, replacement of internal and external facade layers and the depth of cavity. The simulation findings have been distributed to various comparison groups and the ratios of meeting 300 lx – 500 lx value suggested in office buildings have been analyzed. When the obtained results are examined, it can be understood that the daylight can be used at an optimal level with some interventions that can be applied in the design process of the double-skin facades.

    Optimizing the Window Size and Depth of a South-Facing Room With Prismatic Panels for a Better Daylight Performance
    (Izmir Institute of Technology, 2019) Köse, Fatma Büşra; Kazanasmaz, Tuğçe
    In a conventional side-lit room, light levels decrease rapidly as room gets deeper, resulting in excessive daylight exposure near the perimeter zones and need for artificial lighting at the back of the room. Therefore, it is not possible to achieve good lighting performance throughout the room unless any daylight strategy is developed. Advanced daylighting systems are developed to figure out this problem. Prismatic daylight-redirecting panels, for instance, improve daylight distribution through sun shading and redirection. This study mainly focuses on the performance of daylight redirecting prismatic panels attached in a south-facing, side-lit room with different room depths and windowto- wall-ratios (WWR). A deep-plan classroom was chosen as a reference case. The methodology is based on simulating the base model in Relux and testing it with alternative models composed of incrementally defined WWR and room depth values. The on-site measurements were performed to evaluate current daylight conditions and validate the simulation model. Illuminance values obtained throughout the room were evaluated in terms of the latest daylighting metrics and visual performance recommendations. Furthermore, simulation findings were used as inputs in constructing a multiple regression model to analyse the relation between room depth, window-towall- ratio and daylight illuminance. The study presents the optimal window-to-wall ratios in relation with varying room depths when prismatic panels are attached. It is considered that the requirements mentioned in standards can be revised taking account of advanced daylighting systems. Besides, the prediction model estimating illuminance in such design alternatives would be integrated in the initial design phase.

    Testing Room and Window Design Parameters for Daylight Performance According To Breeam Assessment Criteria: Cases of London and Izmir
    (Izmir Institute of Technology, 2019) Sönmez, İrem; Kazanasmaz, Tuğçe
    Daylight affects occupants' visual performance in the indoor environment. The amount of daylight determines the quality of the interior. If daylighting is controlled properly, it provides comfortable and healthy spaces for the occupants. It is the primary light source of interior and it saves energy decreasing the use of artificial lighting in the interior. Because of these reasons, daylight performance has a significant role in environmental assessment tools. As BREEAM is the first environmental assessment tool in the world which is published in the UK, it has been the subject matter in this thesis. BREEAM has 'Daylight' section in 'Health and Wellbeing' category. The illuminance value determines whether to get the credits or not in this category. It has been known that there are architectural parameters such as window size and surface reflectance that affect the illuminance value of the interiors. Each color combination of floor, wall, and ceiling results in a significant average reflectance value. Thus, the purpose of this thesis is to test the whole impact of these room and window design parameters on daylight performance according to BREEAM(universities, colleges, and higher education-occupied spaces) criteria with the cases of London and İzmir. The daylight performance simulation models of the reference rooms generated with four material alternatives were built in RELUX, under clear and overcast sky conditions. Simulations run for London and İzmir covering solstice and equinox days. Findings were discussed in the view of daylighting criteria of BREEAM. In general, daylight criteria of BREEAM which is based on conditions of London (UK) were found to be suitable and applicable for cases in İzmir.
