    Optimizing the Window Size and Depth of a South-Facing Room With Prismatic Panels for a Better Daylight Performance

    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, Zehra Tuğçe; Kazanasmaz, Tuğçe; 02.02. Department of Architecture; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    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.
