Design and analysis of energy saving buildings using the software energy plus

Birol, Kemal Özgen
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, building envelope design, lighting and day lighting design and HVAC system design. Energy Plus® software is mainly developed to simulate the performance of the buildings in the view of the above listed points. The design of a building or the analysis of an existing building with the software will show how efficient the building is or will be, and also helps finding the best efficient choice of the whole building system. Thesis focuses on the effect of changes in building envelope properties. In Turkey, topic of green buildings has recently started to be studied. Therefore, this thesis aims to present efficient technologies providing energy savings in buildings, to present green building concept and alternative energy simulation software. In the context of this study, design, methods and material guidelines are introduced to reduce energy needs of buildings and to bring in the green building design concept. Building and system parameters to enhance building energy efficiency and energy savings together with green building principles are summarized. Moreover, whole building energy analysis methods and simulation steps are explained; year-round simulation is performed for a sample building; as a result, energy savings about 36% is achieved.


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 smart buildings: simulating the impact of active systems and passive strategies
Tetik, Buğra; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2014)
Energy efficiency is one of the most important attempts in the world because of various environmental, economical and developmental aspects of energy. In this context, energy performance of buildings has been a critical issue since buildings constitute approximately half of total energy consumption. The concept of smart building which has been attractive recently, contributes to the issue with smart technologies; while some passive design techniques which have been used throughout the history are still appl...
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...
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...
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...
