This chapter discusses leading problems linked to energy that the world is now confronting and to propose some ideas concerning possible solutions. Oil deserves special attention among all energy sources. Since the beginning of 1981, it has merely been continuing and enhancing the downward movement in consumption and prices caused by excessive rises, especially for light crudes such as those from Africa, and the slowing down of worldwide economic growth. Densely-populated oil-producing countries need to produce to live, to pay for their food and their equipment. If the economic growth of the industrialized countries were to be 4%, even if investment in the rational use of energy were pushed to the limit and the development of nonpetroleum energy sources were also pursued actively, it would be extremely difficult to prevent a sharp rise in prices. It is evident that it is absolutely necessary to pursue actively the development of coal, natural gas, and nuclear power if a physical shortage of energy is not to block economic growth.

Multi-objective optimization design for windows and shading configuration considering energy consumption and thermal comfort: A case study for office building in different climatic regions of China

Rethinking the limitations of research on occupants’ window-opening behavior: A review

The building envelope, the most important element in the energy consumption of a building, gains more importance due to the large amount of the surface area of building’s facade in high-rise buildings. The energy consumption of these buildings is increasing depending on their high transparency ratio as a result of decrease in the thermal resistance of the facade. The aim of this study is to show the importance of building envelope design in energy efficiency of high-rise residential buildings and to analyze the effect of the building envelope design on energy consumption. Turkey’s highest residential building from 2010 to 2017 was selected for the case building. DesignBuilder program with the EnergyPlus simulation engine was used for energy analysis of the building. The energy consumption results were compared with the other study data in the literature. As a consequence of the simulation conducted according to the existing facade of the building, 25% of the energy is used for heating and 14% for cooling in total energy consumption. It has been found that the building envelope designed with double-layered air corridor can offer the maximum level of residential comfort to the occupants. This study shows that the building facade with air corridor also reduces energy consumption by 30% compared to the same sized buildings.

Healthcare facilities have an important place in Ottoman Architecture. Started to be built during the Anatolian Seljuk period and continued into the Ottoman in many cities, they manage to survive. However, it is not possible to use them with their original functions today. Most of them are used by serving as exhibition and museum buildings like Edirne Sultan 2nd Beyazid Health Complex. In the use of such historical buildings, the examination of their response to changing living conditions and needs is important. This study investigates how the physical environment affected the design of the complex, and the impacts of its planning and building envelope on today’s IEQ. The physical environmental data were discussed about thermal, daylight, ventilation, and acoustics performances by calculating and evaluating the existing energy consumption of the building. Methods like literature review, direct observation, on-site examination, simulation, and documenting with photographs were used. It was determined that five hundred years ago, the building was compatible with its physical environmental data in terms of its function, planning, and building envelope, and, as being a museum today, it provides all the necessary comfort conditions for its users, and that the energy consumption is at an acceptable level.

The effects of physical environment in Ottoman healthcare facilities: 2nd Beyazid Complex in Edirne


Purpose
Many parameters influence the success of sustainable projects (SPs) in the architecture–engineering–construction. One of these important parameters is the project delivery attributes (PDA), which are influenced by the project delivery system (PDS) while affecting the selection of it. This study aims to evaluate the significance of PDAs in influencing both the performance and success of SPs in Turkey, where the interest in SPs is high.


Design/methodology/approach
The impact of PDAs was determined by applying the two-round Delphi method with a semistructured interview involving the main stakeholders of a construction project, like owners, designers, contractors and consultants who played active roles in SPs, as well as academics to theoretically evaluate the issue. The significance of PDAs was assessed using the relative importance index, and the results were validated using the interrater agreement analysis.


Findings
The study identified key PDAs impacting SPs as owner character, commitment and motivation; simulation and energy modelling; and timing of stakeholders/early involvement.


Originality/value
The investigation of the significance of the PDAs is a lesser-studied context. Therefore, a research framework that enables an effective set of methods for solving the sectoral problems of PDAs that have impacts on SPs has been proposed. The framework is expected to open new opportunities for the generation and regulation of the PDSs for SPs. The findings will provide valuable insights to project stakeholders, particularly owners, local authorities and policymakers to assess which PDAs have a greater impact on sustainability performance when setting PDSs in SPs in other developing countries.
