Construction and operation of the built environment is recognized as a significant source of greenhouse gas emissions due to high energy consumption. One of the most critical built environment elements are the external walls. For Turkey, specifically the concrete based external wall systems are of importance. Generally, the concrete based external wall systems are composed of several layers: internal gypsum based plaster, concrete, insulating material, and external plaster. The thermal performance of the wall system not only depends on the type and thickness of the insulating layer, but also on the properties of other system elements. This study focuses on evaluating the use of a typical concrete mix design on the thermal and environmental performance of the wall system. For this purpose, a typical mix design was chosen with a known thermal parameters. Then, a 3D model of the selected wall system was established using Solidworks software. Finite element method based thermal simulation was carried out to calculate the thermal performance of the wall system with the selected concrete mix design. Then, the life-cycle analysis was used to calculate the global warming potential (GWP) for the manufacturing of the wall system. Finally, for a typical concrete based external wall system the effect of the concrete mix design on the GWPs was correlated to the thermal performance of the selected system

The construction sector, being one of the greatest consumers of raw materials, has been under the spotlight for many years in parallel to the increased environmental awareness. Specifically, building of walls are of critical importance. For each wall element, there are different manufacturing steps; but, in general, the emissions from a wall element are dominated by one or two manufacturing steps. For example, for concrete, both energy use and calcination in cement manufacturing are in focus; for clay brick...
Local air quality impacts due to downwash around thermal power plants: Numerical simulations of the effect of building orientation
Kayın, Serpil; Tuncel, Süleyman Gürdal; Yurteri, Coşkun (1999-09-01)
One of the primary adverse environmental impacts associated with power generation facilities and in particular thermal power plants is local air quality. When these plants are operated at inland areas the dry type cooling towers used may significantly increase ambient concentrations of air pollutants due to the building downwash effect. When one or more buildings in the vicinity of a point source interrupt wind flow, an area of turbulence known as a building wake is created. Pollutants emitted from relative...
Impact Assessment of Urban Regeneration Practices on Microclimate in The Context of Climate Change
Akköse, Gizem; Balaban, Osman; Department of Earth System Science (2022-2-10)
The annual ever-increase in population, urbanization, industrialization, and CO2 or greenhouse gas emissions brings with it important environmental crises. Climate change and urban heat islands (UHI) are crucial environmental crises that have serious consequences on the performance of the built environment and the comfort and health of users. Moreover, mass migrations from the urban areas and unhabitable cities are envisaged as a result of climate change. To minimize the impacts of climate change and ensure...
Parametric analysis of BIM-based building energy performance for supporting multi-objective optimization

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 ...
Energy consumption of a day-occupied building utilizing phase changing material incorporating gypsum boards
Akgül, Çağla; Gürsel Dino, İpek (null; 2018-09-14)
In the architecture, engineering and construction industry, there is an urgent need for a shift to low-energy, sustainable buildings to address the environmental concerns, increase occupant comfort demands and lower the operational cost of buildings. In this direction, one of the most effective technologies is using PCM’s (phase change materials) as part of building envelopes. PCMs can increase building performance by increasing the thermal storing capacity of buildings by decreasing the heat transfer betwe...
