Buildings generate millions of tons of greenhouse gases, toxic air emissions, water pollutants and solid wastes that contribute to negative environmental impacts. Life Cycle Assessment (LCA) is a methodology for assessing the environmental performance of products over their life time. However, many building products are discarded much before the end of their service life, especially as a result of refurbishment and renovation projects. The need for such projects is increasing because most buildings are not designed to accommodate changes in their functions and needs of their occupants. This is particular to commercial buildings, especially hospitality facilities, which are unique with regard to operational schemes and the type of services offered that are highly resource-intensive. In this investigation, statistical data related to refurbishment and renovation projects in Turkey were analysed to determine the percentage of refurbishment projects for hotels. Bills of quantities for refurbishment projects of three five-star hotels in Ankara were obtained and evaluated with regard to the volume and type of material discarded as a result of the renovation works. ATHENA, an LCA software, was used to evaluate these projects according to the six environmental impact indicators: primary energy consumption, solid waste, air pollution index, water pollution index, global warming potential and weighted resource use. A system was formulated for evaluating materials according to each indicator by calculating their “eco-scores”; the total score is considered to be the yard-stick for comparing environmental appropriateness of these materials. Finally, recommendations on the choice of materials were made, with an aim to reducing material waste and harmful emissions.

Chemical alteration of oil well cement with basalt additive during carbon storage application
Mokhtari Jadid, Kahila; Okandan, Ender; Department of Petroleum and Natural Gas Engineering (2011)
Capturing and storing carbon dioxide (CO2) underground for thousands of years is one way to reduce atmospheric greenhouse gases, often associated with global warming. Leakage of CO2 through wells is one of the major concerns when storing CO2 in depleted oil and gas reservoirs. CO2-injection candidates could be new wells, or old wells that are active, closed or abandoned. To prevent the leakage, the possible leakage paths and the mechanisms triggering these paths must be examined and identified. It is known ...
Future Mangrove Carbon Storage Under Climate Change and Deforestation
Chatting, Mark; Al-Maslamani, Ibrahim; Walton, Mark; Skov, Martin W.; Kennedy, Hilary; Hüsrevoğlu, Yusuf Sinan; Le Vay, Lewis (2022-02-01)
Mangroves are important sinks of organic carbon (C) and there is significant interest in their use for greenhouse gas emissions mitigation. Adverse impacts on organic carbon storage potential from future climate change and deforestation would devalue such ambitions, thus global projections of future change remains a priority research area. We modeled the effects of climate change on future C stocks and soil sequestration rates (CSR) under two climate scenarios ("business as usual": SSP245 and high-emissions...
Sustainable construction in Turkish higher education context
Topak, Fatih; Tokdemir, Onur Behzat; Pekeriçli, Mehmet Koray; Tanyer, Ali Murat (2019-03-01)
As the construction industry is one of the dominant contributors to the world’s total CO2 emissions and it has huge negative impacts on the environment, sustainable construction has become a key aspiration in the field. Through utilizing eco-friendly design and resource efficiency, sustainable construction is considered as the main concept to create and operate a healthy built environment. Although sustainability has been demonstrated as a timeless objective for continuous development in Turkey’s government...
Literature review on BIM-based building energy performance optimization
Can, Esra; Akçamete Güngör, Aslı (İstanbul Teknik Üniversitesi; 2020-11-14)
Buildings comprise a large part of global energy consumption and make a significant contribution to overall CO2 emissions in the world. Therefore, increasing the energy efficiency of buildings becomes a priority to reduce these undesirable effects. Building energy performance assessments are complex multi-criteria problems as the energy performance is affected by many factors such as building orientation, envelope design, climate conditions, daylighting levels, and HVAC system usage schedules. This complica...
Sustainability Assessments of Urban Railway Systems: Case Study Evaluations in Turkey
YÜKSEL, MÜGE; Tanyer, Ali Murat; Pekeriçli, Mehmet Koray (Springer, 2019-01-01)
There are ongoing efforts to control global warming via reducing CO2 emissions, which are mostly based on human activities. Through life cycle assessment (LCA) carbon footprint (CFP) calculations provide a clear picture of embodied carbon (EC). In this study, the significance of EC estimation and reduction for railway projects are explored. The main motivation is having applicable sustainability strategies for railway systems in Turkey. Since there is no certification system, range or database, these effort...
