Evaluating the impact of different atria configurations on the energy performance of buildings in different climates

Farhoudi, Meysam
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. This study aimed to examine the impacts of different physical properties of an atrium on the energy performance of the atrium buildings in different climates. To be more specific, this research intended to understand the impacts of atrium orientation, aspect ratio and the atrium building height on the heating, cooling and lighting loads of the atrium buildings in different climatic conditions. To examine the effect of each variable on the energy performance of the building several digital models of atrium buildings were prepared and their energy performance were simulated by DesignBuilder software. Each of the atrium buildings were set with different variables to monitor the effects of a single variable or the combination of the variables on the energy performance of the buildings. According to this research, in vi few examined climates the height of the atrium building has the most effect on its energy performance. Though the effect of the atrium aspect ratio on the building energy performance is almost considerable, the atrium orientation does not contribute to it significantly. To further clarify the conclusions, atrium buildings with square shape atria have better energy performance than those with rectangular shaped atria, regardless of the atrium orientation. 


Design and analysis of energy saving buildings using the software energy plus
Birol, Kemal Özgen; Okutucu Özyurt, Hanife Tuba; Oskay, Rüknettin; Department of Mechanical Engineering (2012)
Being the major energy consumer of electricity and natural gas, buildings consume more than 70% of electricity and 30% of natural gas. On the way to green buildings and zero energy buildings, investigation and improvement of energy efficiency of the buildings will result in significant reductions in energy demands and CO2 emissions; make cost savings and improve thermal comfort as well. Key steps of a successful green, energy efficient building can be summarized as whole building design, site design, buildi...
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 ...
Energy performance of duble-skin fa̧acades in intelligent office buildings : a case study in Germany
Bayram, Ayça; Elias Özkan, Soofia Tahira; Department of Architecture (2003)
The building industry makes up a considerable fraction of world̕s energy consumption. The adverse effects of a growing energy demand such as depletion in fossil fuel reserves and natural resources hassled the building industry to a search for new technologies that result in less energy consumption together with the maximum utilization of natural resources. Energy- and ecology-conscious European countries incorporated the well-being of occupants while conducting research on innovative technologies. In view o...
An Approach for improving energy efficiency in a commercial building with learning consideration and availability constraints
Çiçek, Cihan Tuğrul; Meral, Fatma Sedef; Department of Operational Research (2014)
Energy efficiency applications are increasingly becoming more popular as available natural resources such as natural gas and fossils have been running out. In this study, we address the scheduling problem of the heating, ventilation and air conditioning (HVAC) system of a commercial building with a supporting automation system that controls the energy resources so as to increase energy efficiency. We formulate the problem as a multilevel generalized assignment model to obtain the schedule for the HVAC syste...
Parametric analysis of BIM-based building energy performance for supporting multi-objective optimization
Can, Esra; Akçamete Güngör, Aslı; Department of Civil Engineering (2022-5-11)
Building energy efficiency comes into prominence as buildings constitute a significant portion of world energy consumption and CO2 emissions. To achieve energy-efficient buildings, energy performance assessments should be conducted meticulously, yet it is difficult to comprehensively estimate the buildings’ energy consumption since energy performance assessments are complex multi-criteria problems that are affected by many factors such as building orientation, envelope design, climatic conditions, daylight ...
