建材工业是耗能比较多的部门之一。据匡算,我国建材工业总能耗为4500万吨标准煤左右。而且建材企业又遍布全国城乡,绝大多数是中小企业,其特点之一是机械设备比较陈旧,工艺技术比较落后,单位能源消耗比较高。因此,抓好建材工业的节能,对于提高建 Building materials industry is one of the sectors that consume more energy. According to calculations, the total energy consumption of China’s building materials industry is about 45 million tons of standard coal. In addition, building materials companies are located in urban and rural areas across the country. The vast majority of them are small and medium-sized enterprises. One of their characteristics is the obsolete machinery and equipment, relatively backward technology and relatively high unit energy consumption. Therefore, we must pay attention to the energy saving of the building materials industry.
