A Study on the energy efficiency criteria of green campus with a multi-scale approach: METU campus

Apaydın, Özgü
Reducing fossil fuel demand has become a more critical issue within the sustainable development agenda due to the rising concerns about recent climate change. Urban areas currently consume over two-thirds of the world's energy and account for more than 75% of the anthropogenic emissions. In today’s context, tackling climate change and minimizing its impacts require to act urgently and effectively towards reducing energy-related emissions in urban areas. As microcosms and living labs, university campuses are the best possible settings for exploring and practicing sustainability issues. In this respect, an increasing number of universities are committed to a more ‘‘green campus’’ to be primarily upon the energy issue by applying a variety of actions and strategies to their campuses. Literature, however, shows that the trend of transition into an energy-efficient campus for universities still lacks the core leading. The interventions and strategies applied by universities are generally framed by the Campus Sustainability Assessment (CSA) tools. Yet, the energy criteria of CSA tools limited to achieving energy savings with retrofit technics in building scale, green building certification, and green technology usage. Therefore, further research, the involvement of different disciplines, and the integration of energy-efficient design measures; all these are waiting for further promotion. To that end, the study has two primary objectives: (1) based on the literature review to provide a multi-scale evaluation tool to investigate campus operations upon energy efficiency first as an organization and second as a physical settlement with a multi-scale approach, namely on building scale, on building configuration scale, and campus-scale (2) to evaluate the Middle East Technical University (METU) Campus greenness over energy efficiency with the generated assessment chart. The major contributions of this study are extending the understanding of the green campus concept in terms of energy efficiency and presenting a methodology that can be used to enrich the criteria of the CSA tools.


A techno-economic feasibility study of a gridconnected hybrid solar pv-wind power generation system in Zimbabwe
Samu, Remember; Fahrioğlu, Murat; Sustainable Environment and Energy Systems (2019-1)
The depletion of fossil fuel resources on a worldwide basis and an increase in greenhouse gas emissions and climate change as a whole have caused an urgent search for alternative sustainable energy sources to cater for the rising energy demands. The demand of energy is rapidly growing in both developing and developed nations thus making hybrid renewable energy power systems (RES), comprising Solar Photovoltaic (PV) and wind energy to be chosen as one of the best alternatives. However, on the downside, these...

Climate change, increasing energy demand, and natural resource depletion lead to a rapid trend in the adaptation of renewable energy technologies. Especially solar energy as the most abundant source, accompanied by decreasing system prices and increasing social acceptance, rooftop photovoltaic systems became one of the most common small-scale energy generation practices. However, renewable energy resources, solar energy exclusively, create imbalanced energy production throughout the day and year. Energy sto...
A Model for Predicting Theoretical Process Energy Consumption of Rotational Parts Using STEP AP224 Features
Uluer, Muhtar Ural; Akkuş, Kadir; KILIÇ, SADIK ENGİN (2013-04-17)
Energy efficiency in manufacturing has become a key concern due to the increased awareness of the adverse effects of global warming. First step for increasing energy efficiency is to quantify the energy consumed for manufacturing processes. This study presents a prediction model for the theoretical energy that is consumed during the manufacturing processes of a rotational part and resulting CO2 release. Theoretical energy is the tool tip energy required to remove the given volume of chip. Prediction model i...
A decomposition analysis of CO2 emissions from energy use: Turkish case
Tunç, Gül İpek; Akbostancı Özkazanç, Elif (2009-11-01)
Environmental problems, especially "climate change" due to significant increase in anthropogenic greenhouse gases, have been on the agenda since 1980s. Among the greenhouse gases, carbon dioxide (CO2) is the most important one and is responsible for more than 60% of the greenhouse effect. The objective of this study is to identify the factors that contribute to changes in CO2 emissions for the Turkish economy by utilizing Log Mean Divisia Index (LMDI) method developed by Ang (2005) [Ang, B.W., 2005. The LMD...
A policy content analysis for evaluating urban adaptation justice in İstanbul
Williams, David Samuel; Balaban, Osman; Ilhan, Akgün; Paker, Hande; Şahin, Ümit; Sarıkoç Yıldırım, Beyza; Turhan, Ethemcan; Uncu, Baran Alp; Olazabal, Marta (2022-07-01)
Climate change is disproportionately affecting vulnerable communities, increasing existing risks and leading to further global inequalities. Drawing on the concept of urban adaptation justice, we evaluated the inclusion of vulnerable communities in the climate change adaptation planning process of İstanbul, a European coastal megacity with considerable vulnerability to climate change. For this, a policy content analysis structured around four criteria: (i) participation, (ii) capacity enhancement, (iii) gov...
