Abstract The high emissions of substances harmful to the environment associated with the activity of people, has become a point of extreme importance, since it depends on the subsistence of life on the planet [1]. Manufacturing processes and the application of new technologies improve substantially the life, but some processes contribute more to the damage to the environment. These manufacturing processes require a high consumption of energy and resources, which entail environmental impacts, some of them not quantified. For this reason, the reduction of emissions has become the battlefield in the fight for the preservation of planet. To determine and quantify the impacts that occur in a product, process or system, it is necessary to perform an analysis of the flows of energy and resources that occur throughout its life cycle. That is why the LCA has become a very important tool in the process of transition to a low-emission production economy [2]. There are systems that, although considered renewable, also produce impacts on the environment. That is why, the present work, and through the LCA, determines the impacts produced by two heat generation systems, to later be able to compare them with each other.

使用生命周期评估 (LCA) 对热泵系统和生物质锅炉系统与三级建筑进行比较研究

摘要 与人类活动相关的对环境有害的物质的高排放已成为一个极其重要的问题，因为它依赖于地球上生命的生存[1]。制造工艺和新技术的应用大大提高了寿命，但有些工艺对环境的破坏更大。这些制造过程需要消耗大量能源和资源，这会带来环境影响，其中一些未量化。为此，减排已成为保护地球的战场。为了确定和量化产品、过程或系统中发生的影响，有必要对其整个生命周期中发生的能量和资源流进行分析。这就是为什么 LCA 已成为向低排放生产经济转型过程中非常重要的工具的原因 [2]。有些系统虽然被认为是可再生的，但也会对环境产生影响。这就是为什么目前的工作通过 LCA 确定了两个发热系统产生的影响，以便以后能够相互比较。
