“…In this regard, several studies pointed out the beneficial employment of recycled and waste materials as substitutes for virgin materials to reduce the use of raw materials, soil and the energy-intensive processes involved. In particular, several case-studies include the use of industrial [ 30 ], agricultural [ 31 , 32 ], construction and demolition waste [ 33 ], recycled aggregates [ 34 , 35 , 36 , 37 ] and lightweight aggregates (LWA) [ 38 , 39 , 40 , 41 , 42 ] made of waste materials as good candidates to partially substitute natural aggregates [ 43 ].…”

In the last 20 years, there have been a series of seismic events in Italy that have caused serious damage to civil and building structures. This has led to a significant increase in the use of concrete for the reconstruction of new structures and the repair of existing structures damaged by earthquakes. At the same time, the concrete industry is responsible for the most significant environmental damage during the life cycle of the built environment. The environmental disadvantages characterizing the concrete industry are related to the constant growth of the exploitation of natural aggregates. Therefore, it is necessary to use alternative and innovative aggregates that provide good concrete performance and lower environmental impacts. In this study, a very promising route from an environmental point of view is given by the use of artificial aggregates from industrial waste as substitutes for natural aggregates. An innovative low cost and energy saving granulation process has been employed to produce lightweight aggregates using fly ash from the incineration of municipal solid waste and ground granulated blast furnace slag. The final aim of this research is to demonstrate the environmental sustainability of artificial aggregates, through a comparison of three different mixtures.

“…For example, in Malatya [10], Denizli [15,18,22], Erzurum [17], İstanbul [20], Bilecik [23], Bursa [24], İzmir and Ankara [25], Diyarbakır [26]. Moreover, some studies are carried out by selecting only one [27][28][29][30][31][32][33][34][35][36] or more [11][12][13][37][38][39] cities from each climatic zone; furthermore, by merely opting for cold towns [9,14] in Turkey. In most of them, different parameters (types of bricks, insulation materials, and fuels) are investigated by economic and environmental analysis to find the ideal configuration.…”

“…Akan et al [37] produced three different composite materials in different proportions from the mixtures of natural and waste materials and used them to determine the outer wall thickness of the buildings in twelve cities selected from four different climatic zones of Turkey. They determined that the annual energy requirement per unit surface area of the exterior walls of insulated buildings is 11.213-965.715 kJ/m 2 .…”

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.
