Starting with Stockholm Conference, countries have realized that excessive energy use can be the main obstacle in solving environmental problems. Studies have shown that buildings play a key role in consumption and production of energy; and one way forward can be to refurbish existing buildings in a way that they can contribute to the solution. Although there are many reasons to refurbishing existing homes, there are two major barriers that need to be overcome. The first barrier is the initial cost of retrofits and the other is the uncertain attitude of the occupants, regarding the interventions. This study aimed at combining these two issues with building refurbishment strategies and renewable energy usage in existing residential buildings. To this end, two case studies were selected in Ankara, Turkey. The first contains 21 low-rise blocks where 837 people are living; the second is a building complex with three high-rise blocks, having 364 inhabitants. At first, energy consumption of the existing buildings was determined by simulating their models with DesignBuilder software; and then energy retrofit scenarios were proposed. Afterwards, costs and payback periods of the scenarios were calculated with a computer software. Thereafter, questionnaire surveys were conducted to determine the occupants’ attitude towards the proposed retrofits. This thesis presents the results of the simulations with regards to consumption, reduction and production of energy in the buildings before and after retrofitting; and the findings from the questionnaire regarding the change in attitude of occupants due to the financial advantages of the interventions in the long run, rather than information about energy savings only.

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...
Overcoming problems in Turkey's renewable energy policy: How can EU contribute?
Sirin, Selahattin Murat; Ege, Aylin (2012-09-01)
Fossil fuels cover most of the energy demand in the world, and this creates significant social, economic and environmental problems. Many countries have taken measures to increase the share of renewable energy sources (RES), especially in electricity generation, and the review of literature shows that the success of a country in RES diffusion depends on a comprehensive renewable energy policy which combines political commitment with stable and long-term support measures that stimulate technological innovati...
Accelerating mitigation of climate change with sustainable development of energy, water and environment systems
Kılkış, Şiir; Krajacic, Goran; Duic, Neven; Rosen, Marc A.; Al-Nimr, Moh'd Ahmad (2021-10-01)
Integrated approaches across energy, water and environment systems can accelerate the process of mitigating climate change through urgent action. New scientific advances that extend multiple opportunities in this direction have emanated from the 2nd Latin American, 1st Asia Pacific, 4th South East European and 15th Conferences on Sustainable Development of Energy, Water and Environment Systems as represented in this editorial. The review of recent scientific advances connects the 27 research articles in thi...
A review of Ghana's energy sector national energy statistics and policy framework
Asumadu-Sarkodie, Samuel; Owusu, Phebe Asantewaa (2016-01-01)
In this study, a review of Ghana's energy sector national energy statistics and policy framework is done to create awareness of the strategic planning and energy policies of Ghana's energy sector that will serve as an informative tool for both local and foreign investors, help in national decision-making for the efficient development and utilization of energy resources. The review of Ghana's energy sector policy is to answer the question, what has been done so far? And what is the way forward? The future re...
A data-driven approach for predicting solar energy potential of buildings in urban fabric
Duran, Ayça; Gürsel Dino, İpek; Department of Architecture (2022-7)
Energy-efficient buildings that use clean and sustainable energy sources are urgently needed to reduce the environmental impact of buildings and mitigate climate change in cities. Buildings have great potential in harvesting solar energy by their solar exposure capacity. Developments in PV technologies also encourage the integration of PV systems into architectural applications. However, urban contexts can limit solar energy generation capacity of buildings by shading building envelopes and reducing availab...
