Conference Object Citation - Scopus: 2Effect of Building Envelope and Environmental Variables on Building Energy Performance: Case of a Residential Building in Mediterranean Climate(Springer Science and Business Media Deutschland GmbH, 2023) Taşer,A.; Uçaryılmaz,S.; Arsan,Z.D.At least 30% of the World’s energy consumption and greenhouse gas emissions originate from buildings. Thus, design decisions should be well studied during the design phase of buildings following energy efficiency approaches. Environmental variables and properties of the building envelope are significant for energy efficiency. Thus, this study aims to investigate the potential of a residential building in the Mediterranean climate of İzmir, Turkey, regarding decreasing energy use and understanding the significance of architectural decisions during the design stage of buildings. Eight design scenarios were created by defining seven variables affecting energy consumption for room electricity, heating, and cooling. The first three scenarios focused on environmental-related variables, i.e., surrounding buildings, ground surface materials, and building orientation, while the last five scenarios investigated building envelope-related variables, i.e., thermal transmittance of the wall, floor and roof, glass, window frame, and door types, shading elements, and natural ventilation. Then, energy modeling and simulation are applied to test their potential for minimizing energy consumption. Research findings proposed that early architectural design decisions significantly influenced the case building’s energy performance. Thermal transmittance of the building components provided an annual energy saving of 22.4%, thus, was seen as the best-performed variable for the case building. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2023.Article Citation - WoS: 1Citation - Scopus: 2Integration of Daylight Use and Analysis in Double Skin Facades: a Literature Review(Gazi Universitesi, 2024) Kazanasmaz, Tugce; Ünlütürk, Mustafa SerhanDouble skin facades (DSF) aim to save energy reducing the heat losses in buildings. They are visually appeal while allowing to use daylight efficiently. Such facade systems can reduce glare and distribute daylight evenly in the interior when compared to conventional facade systems. That is a result of cavities between two glass facades and locating sun shading elements in them, although this system provides a high level of transparency. As their primary purpose of application is to ensure thermal performance and ventilation, most studies in literature have focused on these. This study started with the hypothesis that studies examining daylight performance in DSFs are more limited than studies examining thermal performance and that daylight optimization methods are not used sufficiently in DSFs. In this context, the study aims to analyze studies focusing on daylight performance of DSFs. The review targets results of such current studies to guide future ones providing feedback knowledge. This may help to better technical developments in such facades and make them prevail in constructions or in retrofitting So, it contributes to literature in this sense. Recent studies are shown in tabulated form and interpreted in detail with graphics. considering their methodologies, daylight parameters and findings. Results show that the daylight parameter is one of the most important issues that architects or designers should consider from the moment they start the design, and they should make their designs based on the optimum penetration of daylight into the building. Consequently, this review presents that the use of daylight optimization has started to be used in recent studies dealing with DSFs. A DSF design can optimally get daylight into the interior can be made by using this method more frequently.Article Citation - WoS: 64Citation - Scopus: 74Optimization of an Envelope Retrofit Strategy for an Existing Office Building(Elsevier Ltd., 2012) Güçyeter, Başak; Günaydın, Hüsnü MuratEnergy-efficient retrofits include improvement of building envelope via insulation, employment of building integrated renewable energy technologies, and climate control strategies. Building envelope improvements with insulation is a common approach, yet decision-making plays an important role in determining the most appropriate envelope retrofit strategy. In this study, main objective is to evaluate and optimize envelope retrofit strategies through a calibrated simulation approach. Based on an energy performance audit and monitoring, an existing building is evaluated on performance levels and improvement potentials with basic energy conservation measures (ECMs). The existing building is monitored for a full year and monitoring data is used in calibrating the simulation model. In order to obtain a better-performing building envelope three retrofit strategies including several ECMs are proposed. Retrofit strategies are simulated through calibrated base-case model, and results are evaluated according to changes in indoor environmental parameters and annual energy consumption measures. The analysis of results indicated that pre-assessed strategies yield close results. Therefore, a more comprehensive evaluation based on different decisive criteria is used in optimization of the final retrofit strategy, with the intention to evaluate the effect of individual ECMs on annual end-use energy consumption and investment.
