Article Citation - WoS: 20Citation - Scopus: 17Optimizing Thermal Comfort in Physical Exercise Spaces: A Study of Spatial and Thermal Factors(Elsevier, 2024) Avcı, A.B.; Balci, G.A.; Başaran, T.Fitness centers have become famous for maintaining a healthy lifestyle. They require different thermal comfort conditions and higher fresh air supply rates than other indoor spaces. However, even well-designed centers may cause discomfort due to factors such as design decisions, ventilation, overheating, and overcrowding. The standards for fitness centers do not consider these specific requirements sufficiently, so this study focuses on understanding the thermal comfort requirements during physical exercise and evaluating spatial and thermal factors affecting the thermal environment around the body. The study investigated the ceiling height, lateral and frontal distances between machines, and vent locations as spatial factors and inlet temperature and air velocity as thermal factors. A thirty-minute moderate-intensity constant work rate exercise test was conducted in a controlled climatic chamber using a cycle ergometer with six healthy male participants. The experiment conditions were simulated in CFD software using the collected data. Once a validated simulation model was provided, computational models for different environmental and spatial scenarios for the five-person cycling class were generated. Using Taguchi L9 (34) orthogonal arrays method, nine spatial scenarios were simulated with three different thermal operations each. Optimal factor levels were determined by using thermal comfort conditions (based on predicted mean vote) around the body's thermal plume. The results showed that a ceiling height of 5 m, lateral and frontal distances of 1 m and 0.5 m between machines, and Type 2 (two inlets mounted on the ceiling) ventilation strategy were optimal for achieving better thermal comfort values in a thermal condition of 18 °C and 0.2 m·s−1. The study found that increasing the ceiling height and using cross-positioned vents that project air vertically from the ceiling improved the comfort conditions significantly. It is expected that these criteria, which were determined, compared with the standards and detailed, will contribute to the production processes of comfortable exercise spaces. © 2023 Elsevier B.V.Article A Case Study on Experiential Learning in Architecture: Accessible, Climate-Responsive, and Flexible House Designs(EMARA: Indonesian Journal of Architecture, 2023) Avcı, Ali Berkay; Beyhan, Şefika GülinArchitectural education is based on acquiring theoretical and applied knowledge. As a result, experiential learning theory was frequently applied to architecture design courses. As experiential learning refers to gaining knowledge by doing, it allows the students to experience implementing the theoretical knowledge and refine their design solutions by communicating with the teachers. The present study aims to integrate experimental learning in a theoretical course named "Building Information" on housing designs for first-year undergraduate architecture students. After eight weeks of the theoretical lecture period, the students were assigned to design a house using one of the specific approaches, namely accessibility, climate responsiveness, or flexibility. The occupants of the houses were defined, and the students determined their spatial needs. After the critique sessions, the house designs were presented with drawings and analogue models as the final product. Three selected examples from each design approach were evaluated in the study. The results showed that the students gained and implemented theoretical knowledge more efficiently with the integration of experimental learning.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.
