Sustainability of high-rise buildings : energy consumption by service core configuration

Güryay, İlkay
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. This dissertation examines the role of the service core configuration on the sustainability of high-rise buildings. In this context, the effect of different core types and locations on the energy consumption of high-buildings is evaluated. For this respect, sixteen alternative configuration models with central, end and split core types are determined as the representative of possible design choices. The alternatives share the same height, net and gross floor area, floor efficiency, materials, internal gains, etc. They just vary in type and location of the service core and orientation of the building mass. Energy consumptions of the sixteen models are tested with eQUEST, a thermal simulation program, by using the climatic data of Istanbul. The simulation is conducted according to two air conditioning scenarios for office and core zones. For both of the scenarios, split core alternatives are found as the most energy efficient configurations regardless of the core location and building orientation. Moreover, it is observed that while the end core alternatives giving average values, central core configurations have the highest energy consumption results, as predicted.


Architectural design for climate change mitigation and adaptation strategies in existing buildings
Akköse, Gizem; Gürsel Dino, İpek; Department of Architecture (2019)
Climate change has been proven largely to be a consequence of human activities and has a destructive impact on ecosystems. Societies and economies have become a growing global concern for the last few years and the building industry has a key role in this change due to its huge amount of environmental footprint. The energy consumption and greenhouse gases emissions of the built environment influence the climate in a negative way while the changing climate also influences the energy and thermal performance o...
Sustainability in architectural education: the impact of education on perceptions of sustainability
Çalıkuşu, Ayça Nilüfe; Bilsel, F. Cânâ,; Department of Architecture (2019)
In recent years, the concept of sustainability has come to the forefront in many areas. The relationship between education and sustainability needs to be examined to understand the broad meaning of the sustainability concept. Architectural education has an important role in understanding sustainability issues and increasing the sustainability awareness of students. Therefore, this study focuses on educational needs for the adoption of sustainability in the architecture. In the study, the design studio educa...
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...
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...
