Together with a global concern for the reduction and conservation of energy, the oil crisis of 1973 brought about a turning point in the design of buildings. Responses in this vein were mostly concentrated on the simplistic one of sealing the building against outdoor conditions. This approach towards energy consumption, associated with the introduction of air-conditioning systems, led to different problems such as Sick Building Syndrome. Lack of user satisfaction also appeared to be a common complaint in such sealed, air-conditioned buildings, leading to a marked drop in employee efficiency and, hence, return on capital investments. In this study, Emek Ishani, a sealed office building located in Ankara, whose curtain wall system was renovated in 2001, was investigated in terms of its natural ventilation potential under two sub-topics. With a survey conducted, user perception towards environmental conditions, and health problems they suffered were investigated. With a computer simulation, natural ventilation potential of the building in terms of energy consumption was examined. It was resulted from the survey that building occupants have serious health problems. They are also not satisfied with the way the ventilation system functions and most of the occupants liked to have a window opening to outside in order to adjust the inner conditions. It was resulted from the computer simulation that integration of natural ventilation did not make any significant difference in the annual energy consumption of the building. On the other hand, cooling loads of the building were eliminated in summer months. As a result, introduction of natural ventilation appeared to be an appropriate tool for more user satisfaction and energy conservation.

Evaluation of natural ventilation systems in tall buildings considering altitude based environmental variations Karadağ, İlker; Zeytun Çakmaklı, Ayşem Berrin; Department of Building Science in Architecture (2014) Buildings relied on natural ventilation strategies alone for many centuries up to the post-World War II period in which cheap energy started to liberate architecture from its connection with the natural environment. Then, the economic downturn in the 1970s, fuelled by the worldwide energy crisis in 1973 drew the attention to reduction and conservation of energy, the response was the model of the sealed glass box with an acceptance of the air-conditioning system. This resulted in Sick Building Syndrome (SBS)...
Thermal bridge detailing in tunnel form buildings with passive house principles Yılmaz, Derya; Tanyer, Ali Murat; Department of Building Science in Architecture (2014) As a result of depleting fossil fuels, increased energy prices and global warming, the growing importance of energy efficiency given birth to spread construction of energy saving buildings and use of new technologies around the world. Since thermal bridges in buildings may cause excessive heat loss, mold growth and deterioration of indoor air quality; to eliminate thermal bridges becomes very crucial both in existing buildings and in energy efficient buildings. In this thesis, energy demand of a six storey ...
Application of Hubbert Peak Theory to Stimulate Biogas Production Zuberi, M. Jibran S.; Fahrioglu, Murat (2015-01-01) Assessing the amount of fossil fuels remained in the subsurface, specifically oil and gas has been debated extensively since the introduction of Hubbert Peak Theory in 1956. The economic model of Pakistan relies greatly on natural gas. Thus, estimating the volume of natural gas recoverable in the future becomes critical for the development of the country. The main objective of this paper is to examine the applicability of Hubbert Peak Theory in order to determine the ultimate gas recovery under a pessimisti...
Sustainability of high-rise buildings : energy consumption by service core configuration Güryay, İlkay; Günel, Mehmet Halis; Department of Building Science in Architecture (2012) The concept of 'sustainability' came into question during the last few decades world-wide. As one of the main source of carbon emission, construction industry is also affected by this movement. High-rise buildings which became proliferative components of construction industry dominate today's urban centers. Although they are defended as being inherently energy efficient by some people, specially designed sustainable high-rise building examples emerged after the sustainability movement all over the world. Th...
Evaluating the impact of different atria configurations on the energy performance of buildings in different climates Farhoudi, Meysam; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2016) Generally, the impact of the building sector on the world energy consumption and environmental protection is considerable; in fact, the building sector holds the half of the world total energy consumption share. Nowadays, energy efficiency phenomena as the result of several challenges that the world is encountering has become an important issue. Meanwhile, the atrium as a tool to improve the energy performance of a building can be utilized to address the high energy consumption of the conventional buildings...
