    Designing façade and envelope for a high-rise residential building using energy-efficient materials: A case in Istanbul, Turkey
    (IOP Publishing, 2022) Azima, Mahshad; Seyis, Senem; Civil Engineering; KAZAZOĞLU, Senem Seyis; Azima, Mahshad
    The construction industry is responsible for 40% of global energy demand as buildings increase heating, cooling, and lighting demand. Therefore, building energy performance has become one of the most significant subjects for the architecture, engineering, and construction (AEC) industry in the last decade. The envelope of a building has an essential role in optimizing energy performance and consumption. The research objective of this study is to analyse and compare the impact of different envelope and facade materials on building energy performance for a high-rise residential building. The research methodology includes a literature review and a case study. The literature review analysed studies published between 2015 and 2021. In the literary review, 84 publications were extracted from Web of Science and Scopus databases, and the following sources were included: articles published in prominent journals, conference proceedings, thesis, scientific reports, and books. In the case study, passive strategies including building shape, orientation, insulation, window-wall ratio, and shelter were implemented in a 10-story residential building in Istanbul, Turkey. Design-Builder and EnergyPlus were used for analysing and comparing the energy performance of the different wall, insulation, and glass materials used in the building. Results demonstrate that each parameter and material has a considerable impact on the building energy performance. This study would contribute to the AEC literature and industry by comparing different envelope materials' energy performance and the proper scenario according to Turkey(Istanbul)'s climate. Policy-makers and decision-makers can benefit from the results of this research and amend the existing codes and policies for new high-rise buildings.

    Influence of office building design on occupant satisfaction
    (IOP Publishing, 2022) Artan, D.; Ergen, E.; Tekçe, Işılay; Yılmaz, N.; Interior Architecture and Environmental Design; TEKÇE, Işılay
    The objective of this study is to examine the influence of building design on office occupants by analysing empirical data on their satisfaction levels and prevalent complaints. A methodology involving literature review, expert interviews, and a field survey with 308 office employees was adopted to acquire the empirical data. The findings reveal that office occupants think Amount of Space as the most important parameter, followed by Layout, and Furniture. On the other hand, occupants are least satisfied by Amount of Space, followed by Interior Design and Layout. Insufficient social areas, insufficient work space, and layout of the work environment, distraction caused by human circulation due to office layout, and ergonomics of the furniture are the most common complaints. The results show that average importance level in each building design parameter is higher than or equal to the average satisfaction level. The largest gap between the perceived importance and satisfaction appears in Amount of Space and Layout. The results are expected to provide insight to designers, facility managers, and renovators of office buildings on how office occupants perceive office building design and frequent complaints encountered in the offices.

    Precision measurement of the structure of the CMS inner tracking system using nuclear interactions
    (IOP Publishing, 2018-10-29) Sirunyan, A. M.; Işıldak, Bora; Natural and Mathematical Sciences; IŞILDAK, Bora
    The structure of the CMS inner tracking system has been studied using nuclear interactions of hadrons striking its material. Data from proton-proton collisions at a center-of-mass energy of 13 TeV recorded in 2015 at the LHC are used to reconstruct millions of secondary vertices from these nuclear interactions. Precise positions of the beam pipe and the inner tracking system elements, such as the pixel detector support tube, and barrel pixel detector inner shield and support rails, are determined using these vertices. These measurements are important for detector simulations, detector upgrades, and to identify any changes in the positions of inactive elements.
