Abstract

The construction sector is one of the branches of the economy with a significant impact on the environment. It uses a vast amount of different raw materials. Also, it produces substantial amounts of waste and emits high amounts of greenhouse gases into the atmosphere. Reducing the energy consumption and emissivity of buildings, decarbonizing existing energy sources, optimizing the use of renewable energy, and minimizing the carbon footprint of materials and construction works are imperative to counteract climate change. It is also a minimum plan for ensuring sustainable social development. The current environmental policy in the construction sector is insufficient and it results from the legal regulations currently in force. Assessment of construction products for the seventh basic requirement, sustainable use of natural resources, is voluntary and almost always neglected. Assessment tools, such as Type III Environmental Product Declarations [EPDs] for construction products, are not widely used. Moreover, these documents are poorly recognizable among consumers, proving that there is still insufficient environmental awareness. In addition, the emerging differences in environmental impact indicators values specified in environmental declarations, resulting from using differentiated approaches in setting system boundaries or the quality of available generic data, do not support the proper development of knowledge about the impact of construction products on the environment. In this work, an analysis of the environmental impact of cement, which is a component of adhesives used in the External Thermal Insulation Composite System [ETICS], was carried out. The study on four indicators, i.e., global warming potential [GWP], soil and water acidification potential [AP], eutrophication potential [EP], and tropospheric ozone formation potential [POCP], was performed.

水泥对建筑产品环境性能的影响,以水泥胶粘剂-外保温复合系统[ETICS]组件为例
建筑业是对环境有重大影响的经济部门之一。它使用了大量不同的原材料。此外,它产生了大量的废物,并向大气中排放了大量的温室气体。减少建筑物的能源消耗和排放,使现有能源脱碳,优化可再生能源的使用,并尽量减少材料和建筑工程的碳足迹,这些都是应对气候变化的必要措施。它也是确保可持续社会发展的最低限度计划。目前建筑行业的环境政策是不充分的,这是由现行的法律规定造成的。对建筑产品的第七个基本要求——自然资源的可持续利用——的评估是自愿的,几乎总是被忽视。评估工具,如建筑产品的III类环境产品声明(EPDs),并没有被广泛使用。此外,消费者对这些文件的认可度较低,证明环保意识仍然不足。此外,由于在设定系统边界或现有一般数据的质量方面使用不同的方法,环境声明中规定的环境影响指标值出现了差异,这不利于适当发展关于建筑产品对环境影响的知识。在这项工作中,对水泥的环境影响进行了分析,水泥是外保温复合系统[ETICS]中使用的粘合剂的一种成分。对全球变暖潜势(GWP)、土壤和水体酸化潜势(AP)、富营养化潜势(EP)和对流层臭氧形成潜势(POCP) 4个指标进行了研究。
