Climate Change Impact on Multi-Objective Optimization: A Case Study on Educational Buildings
Akın, Şahin; Işeri, Orçun Koral; Akgül, Çağla; Erdoğan, Bilge; Gürsel Dino, Ipek (null; 2020-05-23)
The changing weather conditions due to global climate change is expected to have a direct impact on buildings’ energy demand and occupant comfort. These conditions are estimated to become more challenging for educational f...
Experimental and theoretical study on elastic properties of crystalline alkali silicate hydrate
Moon, Juhyuk; Kim, Seungchan; Akgül, Çağla; Bae, Sung-Chul; Clark, Simon Martin (Elsevier BV, 2020-01-05)
Mechanical properties of synthesized sodium silicate mineral, Na-kanemite, was investigated by synchrotron-based high-pressure x-ray diffraction experiment and first-principles calculations. Under hydrostatic pressure, the...
Effect of envelope insulation on building heating energy requirement, cost and carbon footprint from a life-cycle perspective
Altun, Murat; Akgül, Çağla; Akcamete, Asli (Journal of the Faculty of Engineering and Architecture of Gazi University, 2020-01-01)
Space heating is the dominant item of energy consumption of buildings in Turkey. Effective building envelope insulation, especially in early design phase, is the most common passive solution that significantly reduces the ...
Dış sıcaklık verisinin bina ısıtma enerji gereksinimine etkisinin ve TS 825 derece-gün bölge kümelendirmesinin geçerliliğinin incelenmesi
Altun, Murat; Akçamete Güngör, Aslı; Akgül, Çağla (2020-01-01)
Dış sıcaklık verisi, binaların enerji gereksinimi hesaplamasını etkileyen en önemli parametrelerden biridir. Hacimsel ısıtma ağırlıklı enerji tüketiminin görüldüğü Türkiye’de, binaların ısı yalıtımı tasarımının yapılması v...
Impact of climate change on the existing residential building stock in Turkey: An analysis on energy use, greenhouse gas emissions and occupant comfort
Gürsel Dino, İpek; Akgül, Çağla (Elsevier BV, 2019-10-01)
With the growing need for residential buildings as a result of population growth, the building sector is a high-priority area in climate change due to its large share of CO2 emissions, the significant energy saving opportu...
