An Energy and economic efficiency comparison of the building envelope of an apartment building in Ankara, Turkey

Ahmed Shorbagi, Mustafa Ibrahim Saeed
The main aim of this thesis is to study the energy and the economic performance of the building envelope of an apartment floor consisting of three flats in Etlik, Ankara. Three flats namely flat-1 facing South-West, flat-2 facing South-East and flat-3 facing North are considered. Three different glazing window types namely ISICAM KLASIK, ISICAM SINERJI and ISICAM SINERJI 3+ with different thermal transmittance values are investigated as well as the Base Case wall section, four wall sections involving Aerated Autoclaved Concrete Blocks, four wall sections involving Heavyweight Concrete Blocks and four wall sections involving Lightweight Concrete Blocks. The wall sections applied are of different configurations one without insulation and the remaining three are having insulation on the exterior, sandwiched and in the interior. Both the initial investment and operation costs of all these alternatives are found and a performance sequence is obtained to find out the most efficient alternative. In terms of the glazing window units, the most efficient alternative both energy wise and economy wise is ISICAM SINERJI 3+ for flat-1 and flat-2. The result for flat-3 is an exception because it received the least solar energy making the ISICAM KLASIK glazing unit the most efficient. When considering both the energy and economy performance of the wall sections, the most efficient are those with insulation in the exterior and interior for both the AAC Blocks and Lightweight Concrete Blocks. This is mainly due to the low conductivity values of AAC blocks followed by the Lightweight Concrete Blocks.


The development of a building energy performance evaluation program (EnAd) for architectural design process
Çakıcı, Fatma Zehra; Sorguç, Arzu; Department of Building Science in Architecture (2013)
Energy performance in buildings has become one of the most broadly debated subjects in contemporary architecture; and current legislation has emphasized its importance by requiring buildings to possess an energy performance certificate. Due to the technological advances in computational tools, it is possible to analyze the energy performance of buildings before construction starts; however most energy performance evaluation tools, requiring complex solid models and high technical knowledge in the field, can...
Optimizing the fenestration of typical Turkish school building with respect to daylight and thermal performance
Dilber Kılıçarslan, Damla; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2013)
The aim of this study is the maximization of the occupant comfort with the minimization of the energy consumption for artificial lighting, heating and cooling in typical Turkish school buildings through the better design of the fenestrations which were predetermined with a directive called “Eğitim Yapıları Mimari Proje Hazırlanması Genel İlkeleri” i.e. the “General Principles For Preparing Architectural Projects For Educational Buildings” as a monotype regardless of orientation and climate. The study was co...
Assessing the airtightness performance of container-like buildings in relation to its effect on energy efficiency
Bekboliev, Mirbek; Tanyer, Ali Murat; Department of Building Science in Architecture (2015)
This study analyzes the effect of airtightness on the energy efficiency of single and adjacent containerized buildings, before and after refurbishment. It further gives an overview of air leakage problems found in the sample of prefabricated buildings manufactured and located in Turkey. The air leakage of standard container-like building depends on a number of factors like the age of the building, manufacturing quality and quality of assembly implementation. The airtightness of four typical containerized bu...
Modelling of strengthened hollow brick infills
BARAN, MEHMET; Ozcelik, Ramazan; Sevil, Tugce; Canbay, Erdem (2013-02-01)
Strengthening the existing hollow brick infill walls by bonding high-strength precast concrete panels or applying steel fibre reinforced mortar was found to be an occupant-friendly seismic retrofitting technique for the buildings in use with deficient reinforced concrete structural systems. Both techniques convert the existing non-structural hollow brick infill walls into load-carrying structural members. To verify the effectiveness of the techniques, 20 reinforced concrete frames with hollow brick infill w...
