The World Bank data states that by 2030 the urban population will reach about 5 billion with two thirds of those living in cities. Therefore, it is essential that cities plan their strategies for this quick growth (https://www.un.org/development/desa/dspd/2018/10/inclusive-families/). Within the scope of sustainability in Europe in the 2000s, it was stated that it was necessary to produce new industrial technologies based on the modular, stockpile and reversible elements, as well as to reduce energy use through the form of the buildings, the method of construction and urban design elements (Okşak, 2011). 31st October was designated as World Cities Day by the United Nations General Assembly (2013) and it was followed by the 2015 – 2030 agenda of Sustainable Development Goals (SDGs), accepted in 2015 in Sendai, Japan, which had a critical role in the promotion of the international community’s interest in global urbanisation. Within the 17 goals, the 11th is entitled Sustainable Cities and Communities. According to UN data from 2016, 90% of urban dwellers breathe unsafe air and ambient air pollution has caused 4.2 million deaths (https://www.un.org/sustainabledevelopment/cities/). Therefore, minimising air pollution and reducing energy consumption is one of the primary goals to achieve better urbanisation and the well-being of citizens. In this sense, embedded energy and the use of environmentally-friendly materials have become more important than ever. The State Planning Organization of Turkey (DPT), active in the 2000s, supports orientation to renewable energy sources, do-it-yourself systems, pre-fabricated building technologies, and structures suitable for extension (DPT 2001-I), (DPT 2001-II). The aim of this work is to make a comparative study about the use of construction materials such as concrete and wood. These and similar studies are thought to encourage the use of environmentally sensitive and natural materials in future designs. The data will be gathered from official statistical data.
