Thermal insulation aerogel products are characterized by the low thermal conductivity and excellent environment-friendliness, thus serving a research hotspot in the fields of green buildings and industrial energy conservation. This paper includes the systematic analysis on the Green Product Evaluation of thermal insulation aerogel products, covering resource consumption, energy efficiency, emission and product quality. The results show that aerogel products significantly reduce energy losses, thanks to their ultra-low thermal conductivity. In the entire life cycle, they reduce energy consumption by more 20–30% than traditional thermal insulation materials (such as rock wool and polystyrene). In addition, the environmental load can be further reduced to optimize the raw material selection and preparation process. Performance parameters (such as thermal conductivity, and compressive strength), environmental protection suggestions (such as non-toxicity and recyclability), and economic feasibility are considered in the definition of the assessment evaluations to promote the large-scale application of aerogel products in the green, low-carbon fields. This finding can provide the theoretical basis and technical reference for the decision-making on the green certification standards for SiO2 Base thermal insulation aerogel materials.

摘要

Thermal insulation aerogel products are characterized by the low thermal conductivity and excellent environment-friendliness, thus serving a research hotspot in the fields of green buildings and industrial energy conservation. This paper includes the systematic analysis on the Green Product Evaluation of thermal insulation aerogel products, covering resource consumption, energy efficiency, emission and product quality. The results show that aerogel products significantly reduce energy losses, thanks to their ultra-low thermal conductivity. In the entire life cycle, they reduce energy consumption by more 20–30% than traditional thermal insulation materials (such as rock wool and polystyrene). In addition, the environmental load can be further reduced to optimize the raw material selection and preparation process. Performance parameters (such as thermal conductivity, and compressive strength), environmental protection suggestions (such as non-toxicity and recyclability), and economic feasibility are considered in the definition of the assessment evaluations to promote the large-scale application of aerogel products in the green, low-carbon fields. This finding can provide the theoretical basis and technical reference for the decision-making on the green certification standards for SiO2 Base thermal insulation aerogel materials.
