Implementation of Green Building Standards Highlights Full‑life‑cycle Performance of Daylighting Building Materials

Domestic specifications for green and low‑carbon buildings keep improving, setting more detailed requirements for energy‑saving performance, carbon emission control and building‑material durability of industrial constructions. Previously, project material selection mainly focused on factory‑outlet indicators such as initial light transmittance, while ignoring performance degradation after long‑term outdoor service. With the implementation of standard systems, evaluation dimensions for daylighting building materials have expanded from initial parameters to full‑life‑cycle performance. Long‑term indicators including weathering resistance, thermal insulation, impact safety, and retained light transmittance are regarded as key assessment items.

Such a shift greatly changes material‑selection logic. Project owners pay more attention to real‑world long‑term performance rather than short‑term lab test results. It also guides manufacturers to adjust R&D priorities, moving away from over‑emphasis on short‑term indicators. More focus is placed on long‑term material stability, balancing safety, energy efficiency and durability throughout the product lifecycle, so as to support low‑carbon and long‑term operation of industrial buildings.
