heal.abstract
This dissertation was written as a part of the MSc in Energy Systems at the International Hellenic University. In this thesis a state of the art research protocol on urban office buildings is performed, with a focus on the parameters that influence its energy perfor-mance from the early design phase. A typical contemporary urban office building was used in order to evaluate various parameters in four different European climates; warm humid, warm dry, cold humid and cold dry. Specifically, several factors are examined, such as window to wall ratio, envelope thermal mass and internal loads to understand which results in lower energy requirements. The results are compared and discussed in terms of the building design. The various parameters are assessed using Energy Plus simulation software. The whole thesis may be used as a useful tool by engineers during design phase to assess the impact of design choices on the energy efficiency of urban office buildings. At this point, I would like to thank my Supervisor Agis M. Papadopoulos Professor Dr. - Eng., in the Department of Mechanical Engineering of Aristotle University of Thessa-loniki for his invaluable help and guidance. The completion of this thesis would not have been possible without his knowledge and supervision. Moreover, I would like to thank my valuable friend and colleague Christina Konstantinidou, Civil Engineer, MSc - PhD candidate at Aristotle University of Thessaloniki for her help and support in providing me the basic knowledge in simulation software. Finally, I would like to thank my friends and colleagues Ifigeneia Theodoridou, Katerina Christodoulou and Anna Psefteli, for their support. I cannot but thank my lifetime support team, the people who helped me begin it all; my family. The academic structure of International Hellenic University made it possible to have a consistent direction in my field of interest and de-velop such a great knowledge within my Master of Science in Energy Systems.
