Conference Object Citation - Scopus: 1Daylight Performance and Lighting Energy Savings of Amorphous and Crystalline Silicon Solar Cells in an Architecture Studio(IEEE, 2023) Taşer, Aybüke; Kazanasmaz, Zehra TuğçeSemi-transparent photovoltaic (PV) glass increased its popularity due to its energy and environmental advantages, which can generate electricity on-site and utilize natural daylight. They use thin-film solar cells to allow daylight to enter space and generate electrical energy. Crystalline and amorphous silicon (a-Si) solar cells are the most prominent in literature and industry due to their high efficiency and sufficient transparency. This study aims to assess the daylight and lighting energy-saving potential of thin-film crystalline and a-Si photovoltaic glass in an architecture studio in Izmir, Turkey. The simulation engine applied two types of solar cells on existing windows to evaluate the advantage of such glass for daylight performance and lighting energy consumption. Spatial Daylight Autonomy (sDA), a climate-based annual daylight performance metric, evaluates the daylight performance of the studio. Research findings note that such solar cells enhance the visual comfort of occupants and the daylight performance of the studio. In addition, crystalline silicon solar cells can cover the studio's whole lighting loads in the summer and fall seasons and balance them up to 66% and 23% in the spring and winter seasons, respectively. These have higher transmittance and peak power, thus; resulting in higher energy and daylight performance. © 2023 IEEE.Article Citation - WoS: 77Citation - Scopus: 95Thermal, Daylight, and Energy Potential of Building-Integrated Photovoltaic (bipv) Systems: a Comprehensive Review of Effects and Developments(Elsevier, 2023) Taşer, Aybüke; Kundakçı Koyunbaba, Başak; Kazanasmaz, Zehra TuğçeAccording to energy consumption data of the European Union, buildings account for 40 % of overall energy consumption in all sectors. The rise in building energy demand seriously affects global warming. To reduce demand, buildings must be designed to be energy-efficient. As part of energy-efficiency initiatives, unique systems that employ renewable energy sources should be implemented in buildings. As a new technology, building-integrated photovoltaics is considered an essential technology to achieve this target. Several variables affect the thermal, daylight, and energy performance of building-integrated photovoltaic systems; related to environmental and photovoltaic-related parameters. Thus, the challenges and effects of these variables on the overall performance of these systems should be investigated. This research analyzes building-integrated photovoltaic implemented studies and presents a state-of-art review of recent developments. The study not only summarizes the existing studies developed in this field so far but also analyzes the variables and makes concrete generalizations and inferences. It enables finding gaps and deficiencies in the literature and provides a better understanding of all the variables that affect the performance of building-integrated photovoltaic systems by interpreting the results in detail and representing them graphically instead of only through textual analysis. Results show that building-integrated photovoltaics contribute to constructing a sustainable future for cities. Developments in this industry motivate researchers in this field, whose work will make it easier to cope with future ecological challenges. It helps to build a more sustainable future for society. With new developments, it will be possible to mitigate the effects of future environmental problems.Article Citation - WoS: 1Citation - Scopus: 1EXPERIMENTAL AND ANALYTICAL EXAMINATION OF THE EFFECT OF DOUBLE SKIN FAÇADE SYSTEM ON BUILDING THERMAL PERFORMANCE;(Turk Isi Bilimi ve Teknigi Dernegi, 2021) Hülagü,S.; Göksal Özbalta,T.; Başaran,T.In this study, heat transfer in conventional single skin façade and double skin façade system was studied experimentally and numerically by using one dimensional time dependent approach and the effects of the façade systems on building energy performance especially heating energy was investigated. In this context, a mathematical model considering user behavior and window aluminum frame element effect was build by zonal analysis method to calculate the heat transfer in single and box type closed cavity double skin façade systems, and build model was experimentally verified. Experimental study was conducted in office spaces having single and double skin façade systems in Ege University, Civil Engineering Building’s south façade in January 2017. Next, verified model was used to study the heat transfer in the façade systems for İzmir’s climatic condition by using monthly average daily data. The change in thermal performance of single and double skin façade systems due to the climatic condition during a year was investigated by using the 10 year average climate data of İzmir (Mediterranean climate). It was found that double skin façade system acts as an insulator preventing extreme indoor temperature values, thus contributing to the indoor comfort level against changing outdoor conditions. ©2021 TIBTD Printed in Turkey.Article Citation - WoS: 4Investigation of Buildings in Alacati in Terms of Energy Efficiency in Architecture(Konya Technical University Faculty of Architecture and Design, 2020) Avcı, Ali Berkay; Beyhan, Şefika GülinPurpose Due to the depletion of natural resources, energy efficiency in buildings has increasingly gained a major priority. As vernacular houses contain accumulated knowledge to adapt to the climate, they have been crucial examples of energy-efficient architecture for the designers. In this manner, the study focuses on Alacati vernacular houses. The purpose of the study is to investigate and compare the energy-efficient architecture properties of different types of tourism accommodation buildings. Design/Methodology/Approach The accommodation buildings are grouped into three categories, namely Accommodation buildings converted from vernacular houses of the area, New accommodation buildings designed in the style of vernacular houses, and Accommodation buildings that have different architectural styles. Selected three sample buildings from each group are evaluated by energy efficiency principles. Building energy simulation models of the nine case buildings in total are developed to determine the building components' contribution to energy consumption by heating and cooling. The values from energy modeling are used to compare the buildings according to the checklist. Findings According to the results of the study, the density of space, natural ventilation, shading elements, and pitched roof type specialties of vernacular buildings reduce heating and cooling load. However, traditional stone load-bearing walls and bay windows, which are the most significant element of the building form, increase the annual energy demand. At the end of the study, Alacati Energy-Efficient Architecture Database Schema is presented in Table 10 as the outcome of the study. Research Limitations/Implications The evaluation of the case buildings merely depends on the annual cooling and heating energy loads of nine randomly selected buildings. Practical and Social Implications The assessment method used in the study provides the opportunity to identify the proportion of the effect of energy efficiency properties on the total heating and cooling load. Furthermore, the Alacati Energy-Efficient Architecture Schema presented as the ultimate product of this study is expected to guide the architects to design energy-efficient accommodation buildings, without compromising the vernacular architectural appearance of Alacati. Originality/Value The study focuses on the separate effects of the properties of Alacati vernacular architecture, instead of focusing on one property, or comparing case buildings on the energy consumption.
