The building sector has a greater impact on the global environment or faces a greater obligation to improve its environmental performance. In buildings that have really long life cycles; renovation and refurbishment contribute more significantly in their life cycle assessment (LCA) that is a methodology for assessing the environmental performance of a product over its full life cycle. At that point, accurate service life prediction plays important role in LCAs. Estimated service life of components, which is a function of reference service life in conjunction with other factors, is generally considered in usage phases of their life. For building components, the occupants decide to make replacements taking into consideration their functional service life. In light of sustainable principles and policies it makes more sense to renovate or refurbish old buildings. Energy consumption in hotels is one of the highest compared to other building types. These refurbishments are really important because the hotels should follow the fashion in order to offer best services. Many of the services to hotel guests are highly resource intensive, whether it concerns energy, water or raw materials. To assess the life cycle of hotels and their components is really useful to understand the importance of LCA from the point of view of sustainability. This study was about to assess the life cycle of the refurbishment project of the five star hotel in Ankara. The estimated service life of changing materials especially the finishing ones is really shorter than their reference service life. A LCA tool, ATHENA is used for analyzing this refurbishment project. According to the results of software analysis, a material matrix was proposed.

The role of exogenous factors in the strategic performance of construction companies IŞIK, ZEYNEP; Arditi, David; Dikmen Toker, İrem; Birgönül, Mustafa Talat (2010-03-01) The purpose of this paper is to investigate the role of exogenous factors in the strategic performance of construction companies. A conceptual model is proposed where strategic performance is influenced by a two‐dimensional construct composed of market conditions and strategic alliances.
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...
A data-driven approach for predicting solar energy potential of buildings in urban fabric Duran, Ayça; Gürsel Dino, İpek; Department of Architecture (2022-7) Energy-efficient buildings that use clean and sustainable energy sources are urgently needed to reduce the environmental impact of buildings and mitigate climate change in cities. Buildings have great potential in harvesting solar energy by their solar exposure capacity. Developments in PV technologies also encourage the integration of PV systems into architectural applications. However, urban contexts can limit solar energy generation capacity of buildings by shading building envelopes and reducing availab...
Life cycle assessment of a basic external drywall system in Turkey Akgül, Çağla; Özcelik, Gökçe (null; 2014-10-24) 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...
An Evaluation of Environmental Responsibility and Its Associated Factors: Reflections from PISA 2006 Erbaş, Ayhan Kürşat; Teksöz, Gaye; Öztekin, Ceren (2012-12-01) Problem statement: Contemporary global environmental problems have highlighted the importance of acting responsibly towards natural resources and the environment. The role of science education in shaping how people interact with the environment, therefore, has gained importance. The science education community has responded to this challenge by helping citizens develop responsibility for environmental issues. Accordingly, "scientific literacy and the environment" was one of the research areas in the Program...
