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 annual heating energy requirement of the building. This work aims to assess the effectiveness of additional envelope insulation investments at the early design phase of buildings for all cities in Turkey. The study utilizes the current (2008) and draft 2013 versions of the TS 825 standard "Thermal insulation requirements in buildings". In the study, the effectiveness of insulating an uninsulated building according to TS 825 has been investigated for two different time periods: short term (savings on annual heating energy requirement, additional insulation cost and additional greenhouse gas emissions), and life cycle (life cycle cost and greenhouse gas emissions). In addition, the cost and emission payback times have also been analyzed. Analyzes have shown that insulations based on the standard provides improvements of up to 75% for annual heating energy, 70% for lifecycle cost, and 73% for lifecycle greenhouse gas emissions. Payback periods are under 7 years for the cost and under 2 years for the greenhouse gas emissions.

Climate change impact assessment in residential buildings utilizing RCP4.5 and RCP8.5 scenarios
Akgul, Cagla Meral; Gürsel Dino, İpek (Journal of the Faculty of Engineering and Architecture of Gazi University, 2020-01-01)
Buildings - especially the residential buildings - are among the high priority areas in climate change due to their large share of CO2 emissions, their significant energy saving potentials and the increased comfort expectations of their occupants. A systematic and numerical investigation of how building performance will be affected by climate change in the future is crucial for both retrofitting the existing buildings and making long-term strategical decisions. This paper presents the simulation-based resul...
Effect of hot water curing on the mechanical properties and durability of cement mortars incorporating silica fume
Ince, Ceren (Journal of the Faculty of Engineering and Architecture of Gazi University, 2020-01-01)
It is known that curing temperature plays an important role on the fresh and hardened properties of cement-based materials. The increase in curing temperature at early period results in an accelerated hydration reaction that increases the rate of strength development of cement-based materials. However, the application of very high temperatures during curing negatively affects the strength and durability of the cement-based materials generally due to the expansion that takes place in the matrix. The main pur...
Effects of masonry infill walls on the seismic performance of buildings
Öztürk, Mehmet Selim; Akyüz, Uğurhan; Department of Civil Engineering (2005)
In Turkey, in most of the reinforced concrete buildings, hallow masonry infill walls are used as a non-structural element, during design stage, their contribution to overall building behavior is not well known. Observations made after the earthquakes revealed that these non-structural elements had beneficial effects on the lateral capacity of the building. In this study, the contribution of the hallow masonry infill walls to the lateral behavior of reinforced concrete buildings was investigated. For this pu...
Assessing thermal performance of office building envelopes : a case study on energy efficiency
Sürmeli, Ayşe Neşen; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2004)
In this study, the energy conservation potential of selected retrofitting interventions on an office building were investigated, on the basis of which some rational strategies for the improvement of building envelopes in terms of energy, environment and comfort design were proposed. Examined were various measures on envelope constructions that can be retrofitted to existing buildings. By using simulation techniques, the effectiveness of such measures in reducing energy consumption and environmental threat w...
Effect of High-Density Nanoparticles on Recrystallization and Texture Evolution in Ferritic Alloys
Aydoğan Güngör, Eda; Carvajal-Nunez, Ursula; Vogel, Sven C.; Li, Meimei; Maloy, Stuart A. (MDPI AG, 2019-03-01)
Ferritic alloys are important for nuclear reactor applications due to their microstructural stability, corrosion resistance, and favorable mechanical properties. Nanostructured ferritic alloys having a high density of Y-Ti-O rich nano-oxides (NOs < 5 nm) are found to be extremely stable at high temperatures up to similar to 1100 degrees C. This study serves to understand the effect of a high density of nano-particles on texture evolution and recrystallization mechanisms in ferritic alloys of 14YWT (14Cr-3W-...
