“…Bektas Ekici et al [19] used different wall components thicker than those used in this study. Ozel [18] made the model calculations for both heating season model building created by the data taken from the State Institute of Statistics (Prime Ministry, Republic of Turkey). Ucar and Balo [13] determined their results according to sandwich wall with insulation material so that their results are lower than this study.…”

“…Kaynakli [17] compiled the optimum thickness of the thermal insulation material applied to the buildings and the studies determining its impact on energy consumption. Ozel [18] analyzed a system with a 20-year life and showed that the optimum insulation thickness value varies between 5.4 and 19.2 cm, the energy savings vary between 86.26 and 146.05 US$/m 2 , and the payback period varies between 3.56 and 8.85 years. Bektas Ekici et al [19] calculated the optimum insulation thickness, energy loss, and payback periods for four cities selected from different climatic regions according to the TS 825 (Antalya in the 1st region, Istanbul in the 2nd region, Elazıg in the 3rd region, and Kayseri in the 4th region).…”

One of the most important considerations to be considered in the design of energy efficient buildings is the thickness of the insulation to be applied to the building. In this study the existing building stock in Turkey has been investigated depending on parameters such as the height and the area. A model building has been created covering all of these buildings. Fuel emission reduction of combustion system was calculated in the case of insulation applied to this model building. Heat loss of the existing building stock and exhaust emissions and the contribution to the country's economy with the model building methodology are also determined. The results show that the optimum insulation thicknesses vary between 3.21 and 7.12 cm, the energy savings vary between 9.23 US$/m 2 and 43.95 US$/m 2 , and the payback periods vary between 1 and 8.8 years depending on the regions. As a result of the study when the optimum insulation thickness is applied in the model building, the total energy savings for the country are calculated to be 41.7 billion US$. And also total CO 2 emissions for the country are calculated to be 57.2 billion kg CO 2 per year after insulation.

“…The authors also discussed the balance between embodied and operational energies for different scenarios. Dylewski and Adamczyk [58] investigated the economic and environmental benefits of thermal insulation of external walls and Ozel [59] evaluated the optimum insulation thickness, energy savings and payback period of some envelope solutions using life cycle cost analysis over a lifetime of 20 years of the building. Studies as the one developed by the former authors should be extended to LSF construction to better understand the trade-off between embodied energy and operational energy, and economic and environmental benefits, regarding this type of construction.…”

The improvement of the use of renewable energy sources, such as solar thermal energy, and the reduction of energy demand during the several stages of buildings' life cycle is crucial towards a more sustainable built environment. This paper presents an overview of the main features of lightweight steel-framed (LSF) construction with cold-formed elements from the point of view of life cycle energy consumption. The main LSF systems are described and some strategies for reducing thermal bridges and for improving the thermal resistance of LSF envelope elements are presented. Several passive strategies for increasing the thermal storage capacity of LSF solutions are discussed and particular attention is devoted to the incorporation of phase change materials (PCMs). These materials can be used to improve indoor thermal comfort, to reduce the energy demand for air-conditioning and to take advantage of solar thermal energy. The importance of reliable dynamic and holistic simulation methodologies to assess the energy demand for heating and cooling during the operational phase of LSF buildings is also discussed. Finally, the life cycle assessment (LCA) and the environmental performance of LSF construction are reviewed to discuss the main contribution of this kind of construction towards more sustainable buildings.
