Against the backdrop of the "Dual‑Carbon" goals, air‑supported membrane warehousing has become a critical solution for the low‑carbon transition of industrial warehousing thanks to its lightweight structure and high‑efficiency energy utilization. Its core advantages are reflected throughout the full life cycle:
I. Reduced Building Materials: Carbon Reduction at Source
Traditional steel‑structure or concrete warehouses consume large amounts of energy for construction materials. Air‑supported membrane warehousing adopts a structure of "membrane fabric + steel cables + foundation":
Greatly reduced material consumption: steel consumption is only 1/30 of traditional buildings, while concrete consumption is cut by over 95%. For a 10,000㎡ warehouse, carbon emissions at the building‑material stage drop from 2040 tons to 56 tons, representing a 97% reduction.
Eco‑friendly membrane fabric: PVDF membrane releases no VOCs with a recyclability rate above 80%, lowering construction waste.
II. Energy Consumption Optimization: Operational Energy Saving
Thermal insulation & air‑tightness: double‑layer membrane plus thermal cotton (thermal conductivity: 0.03W/(m·K)) features low air‑leakage rate and cuts air‑conditioning load by 30%‑50%. In northern regions, a 10,000㎡ constant‑temperature warehouse saves 40,000‑60,000 kWh of electricity annually, reducing carbon emissions by 32‑48 tons.
Natural daylight utilization: membrane fabric with 20%‑30% light transmittance helps a 10,000㎡ warehouse save 292,000 kWh of lighting power per year and cut carbon emissions by 233.6 tons.
Intelligent ventilation: equipped with heat‑recovery devices to reclaim 80% of heat, cutting winter heating energy consumption by over 40%.
III. Construction & Operation‑Maintenance: Reduced Full‑Cycle Impact
Low‑carbon construction: factory prefabrication plus on‑site assembly shortens the construction cycle to 1/3 of traditional projects and lowers construction‑related carbon emissions by 60%.
Lightweight O&M: maintenance cost is only 1/4 of traditional warehouses without high‑energy‑consuming upkeep. The self‑cleaning membrane needs cleaning only 1‑2 times per year, saving water and mitigating pollution.
IV. Practical Industrial Applications
Coal & ore warehousing: zero dust emission. Material loss drops from 5% to below 1%. A 1‑million‑ton‑level warehouse reduces dust by 300 tons annually, saves 40,000 tons of coal, and delivers an indirect carbon reduction of 64,000 tons.
Chemical raw‑material warehousing: high air tightness cuts ventilation energy consumption by 50%, reduces annual VOC emissions by 20 tons and saves 150,000 kWh electricity.
Conclusion
By implementing "reduced building materials ‑ optimized energy consumption ‑ low‑carbon operation & maintenance", air‑supported membrane warehousing provides a low‑cost emission‑reduction solution. Combined with photovoltaic power generation and waste‑heat recovery in the future, it is expected to realize "zero‑carbon warehousing" and facilitate the low‑carbon transition of industry.
