    Analysis of factors affecting IoT-based smart hospital design
    (SPRINGER, 2020-12) ÇALIŞ USLU, BANU; Uslu, Banu Calis; Okay, Ertug; Dursun, Erkan
    Currently, rapidly developing digital technological innovations affect and change the integrated information management processes of all sectors. The high efficiency of these innovations has inevitably pushed the health sector into a digital transformation process to optimize the technologies and methodologies used to optimize healthcare management systems. In this transformation, the Internet of Things (IoT) technology plays an important role, which enables many devices to connect and work together. IoT allows systems to work together using sensors, connection methods, internet protocols, databases, cloud computing, and analytic as infrastructure. In this respect, it is necessary to establish the necessary technical infrastructure and a suitable environment for the development of smart hospitals. This study points out the optimization factors, challenges, available technologies, and opportunities, as well as the system architecture that come about by employing IoT technology in smart hospital environments. In order to do that, the required technical infrastructure is divided into five layers and the system infrastructure, constraints, and methods needed in each layer are specified, which also includes the smart hospital's dimensions and extent of intelligent computing and real-time big data analytic. As a result of the study, the deficiencies that may arise in each layer for the smart hospital design model and the factors that should be taken into account to eliminate them are explained. It is expected to provide a road map to managers, system developers, and researchers interested in optimization of the design of the smart hospital system.

    Energy saving potential and energy audit of a faculty building at Marmara University in Turkiye
    (2022-10-01) VARBAK NEŞE, SEÇİL; ÇALIŞ USLU, BANU; AKPOLAT, ALPER NABİ; DURSUN, ERKAN; Sönmez T., Varbak Neşe S., Çaliş Uslu B., Akpolat A. N. , Dursun E.
    According to the Council of Higher Education\"s records in 2022, one hundred thirty-one public universities operate in Turkiye. If the energy efficiency in faculty buildings is improved by 20%, 1.458 million U.S. dollars savings per year would be possible. This paper presents the energy profile and energy audit of the Faculty of Technology at Marmara University, in Istanbul Türkiye. The energy efficiency opportunities for faculty building are investigated depending on the energy audit results. The fact that the faculty building is uninsulated therefore this situation causes severe energy losses. The annual heating energy requirement of this university building, which has an average construction area of 15,000 m², is 297,728 kWh. Only an average of 56,987 kWh in fuel consumption and up to 20% energy savings can be achieved with thermal insulation. However, when the existing lighting fixtures are replaced with Light Emitting Diode (LED) fixtures, the annual savings amount is $6,198. The results of this study enable search of sustainable solutions for reducing energy consumption and improving energy audits for faculty buildings.
