High energy consumption in building material production has a significant effect on global warming and other environmental pollution, which has brought into prominence building materials whose production consumes less energy and uses renewable energy sources. In particular, the production phase of brick, a commonly used material in building construction, has an important effect on energy consumption. This study aims to obtain and analyse local energy data in each phase of brick production, compare the energy consumption of local brick factories using different kiln types in Turkey, and contribute to the development of processes for energy-efficient brick production. For this purpose, all the necessary energy data were collected from two factories, one of which uses a Hoffman and the other a tunnel kiln in the system boundary from cradle-to-gate. The local energy data were analysed for the two factories on the assumption that they would reflect the data for the same or similar brick production methods and technologies in Turkey, and this local data and data gathered from the literature were compared in terms of energy consumption. The findings point out that while most energy is consumed during the firing process in both factories, the tunnel factory consumes more energy in total than the Hoffman factory because of the clay preparation process and the calorific value and moisture content of the coal used for firing. The study also reveals that the potential exists for energy efficiency gains in brick production in Turkey.

建材生产中的高能耗对全球变暖和其他环境污染具有重大影响，这已使建筑材料突出，这些建筑材料的生产消耗的能源较少，并使用可再生能源。尤其是砖的生产阶段（建筑中常用的材料）对能源消耗有重要影响。这项研究旨在获取和分析砖生产各个阶段的当地能源数据，比较土耳其使用不同窑炉类型的当地砖厂的能源消耗，并为发展节能砖生产工艺做出贡献。为此，从两个工厂收集了所有必要的能源数据，其中一个使用霍夫曼工厂，另一个使用从摇篮到大门的系统边界内的隧道窑。在假定两家工厂将反映土耳其相同或相似砖生产方法和技术的数据的前提下，对当地能源数据进行了分析，并将这些本地数据和从文献中收集的数据在能耗方面进行了比较。研究结果指出，尽管两家工厂在燃烧过程中消耗了大部分能源，但由于粘土制备过程以及用于燃烧的煤的热值和水分，隧道工厂的总能耗比霍夫曼工厂多。该研究还表明，在土耳其的砖块生产中，存在提高能源效率的潜力。
