This study determines the optimum insulation layer thickness to be applied to external building walls considering the heating degree-day (HDD) method, then energy saving costs, payback periods, and carbon dioxide (CO 2 ) emissions are calculated accordingly. The optimisation analysis is performed for four different thermal insulation materials (glass wool, rock wool, extruded polystyrene, and expanded polystyrene). Natural gas is chosen as fuel for heating purposes, and horizontal perforated brick is preferred in the wall. One of the original features in this study is environmental analysis to determine the CO 2 emission for the insulated wall in Turkey provinces. Another feature is that it has the most up-to-date data about HDD values and fuel and insulation material costs. The worst and best insulation materials are obtained as rock wool and glass wool, respectively. The optimum insulation layer thickness for the best case is varied between 0.07 m and 0.23 m, depending on the HDD values of provinces. The annual total energy saving cost is in the range of 4.4-53.5 $/(m 2 year), and the payback period is 0.11-0.38 years. Besides, the reduction in annual CO 2 emission is changed between 53.2% and 94% for the best case, compared to the uninsulated wall.

“…The determination of optimum insulation layer thickness incorporated into the external building wall is still a live subject [42]. Many studies have indicated that the optimum thicknesses depend on different parameters such as heating and cooling degree-day values in cities, the types of bricks, insulation materials, and fuels [13].…”

Many factors and aspects of the construction and operation of buildings depend on climatic parameters and climatic zones, so these will be fundamental for adapting and mitigating the effects of climate change. For this reason, the number of climate-oriented publications in building is increasing. This research presents an analysis on the most-cited climate-oriented studies in building in the period 1979–2019. The main themes, the typologies of these investigations and the principal types of climatic zoning used in these studies were analysed through bibliographic and manual analysis. A broad spectrum of themes directly and indirectly related to climate and climatic zones and buildings was demonstrated. It was found that 88% of all climate-oriented investigations, to one degree or another, are within the scope of the general topic of energy conservation. A thorough understanding of all climate-dependent aspects will help in designing dwellings appropriately in different climate zones. In addition, a methodology that facilitates the establishment of a typology of climate-oriented research is presented. This typology can be used in future research in different scientific areas. It was also revealed that the climate zones of the National Building Codes of China, the USA and Turkey prevailed in the studies analysed.

“…To estimate the heat transition loads used in the determination of optimization of insulation thickness, many works in the literature applied degree-day or degree-hour method which is a crude and simple model under static conditions (Akan, 2021;Aktemur et al, 2021;Bolattürk, 2008;Dombaycı et al, 2006;Hasan, 1999;Çomaklı and Yüksel, 2003;Sisman et al, 2007;Ozkahraman and Bolattürk, 2006;Çomaklı and Yüksel, 2004;Dombaycı, 2007;Dombaycı et al, 2017;Ertürk, 2016;Ertürk, 2017;Yıldız et al, 2008;Kaynaklı, 2008;Mahlia and Iqbal, 2010;Kurt, 2010;Bolattürk, 2006;Kaynaklı et al, 2015;Yu et al, 2009;Özel et al, 2015;Barrau, 2014;Sundarama and Bhaskaran, 2014). However, a more accurate estimation of heating and cooling transition loads is quite important in the determination of the optimum insulation thickness.…”

The base purpose of this work is to use interior design temperatures and the heating and cooling periods, which are determined according to different wall orientations in terms of thermal performance throughout the year, in the calculation of heat transfer characteristics and optimum insulation thickness. This work is realized under dynamic thermal conditions for the climatic conditions of Adana, Turkey. Firstly, the transmission loads for both heating and cooling are determined for uninsulated and insulated walls according to indoor design temperatures: 20, 22, 24 oC. Annual transmission loads, annual average dynamic thermal resistance, annual average time lag, and decrement factor for various wall directions are calculated by using indoor design temperatures determined over the whole year from minimum heating and cooling transmission loads point of view. Then, these loads determined overheating and cooling periods are used for the optimization of insulation thickness. In the uninsulated wall, yearly cooling load is obtained to be 221.37, 152.81, 229.14 and 229.14 MJ/m2 for the south, north, east and west orientations, respectively while yearly heating load is obtained to be 73.54, 138.44, 117.62 and 117.62 MJ/m2. It is observed that the cooling load is more dominant than the heating load under the climate conditions of Adana. It is also observed that the longest cooling period is obtained in south orientation while the shortest cooling period is obtained in north orientation. The optimum thickness of the insulation for Adana is obtained to be 8.4, 8.0, 9.2 and 9.2 cm for south, north, east and west orientations, respectively. The results indicate that the indoor design temperatures and insulation have a significant effect on heating, cooling and total transmission loads. Besides, the results reveal that the wall orientation has an important effect on heating and cooling periods, dynamic thermal resistance, time lag and optimum insulation thickness.
