Carbon Reduction Strategies and LCA Carbon Emission for Temporary Wooden Structures Under the Zero-Carbon Goal:A Case Study of the Corporate Pavilion at the 2024 International Horticultural Exhibition
Concentrated on the corporate pavilion of Chengdu Design Consulting Group for the International Horticultural Exhibition 2024,low-carbon optimization strategies for small temporary wooden structures under the zero-carbon goal are expounded.It explores carbon reduction from the perspectives of the source,process,and end,based on the Life Cycle Assessment(LCA)method for carbon emission accounting.The findings indicate that,for small temporary buildings,the production and processing of building materials have the greatest influence on the lifecycle carbon emissions,accounting for approximately 50.30％to 69.49％,followed by the operational phase,which accounts for about 19.33％to 30.91％.Comparative analysis with a similar volume light steel structure building shows that different measures can achieve a carbon reduction rate of about 36.00％to 68.41％.The carbon emissions per unit area over the building's entire lifecycle(five years)can be reduced to 382 kg CO2eq/m2.The study underscores the importance of integrating carbon reduction strategies at various stages of temporary building construction and highlights the necessity of using the LCA method to assess building carbon emissions.Beyond the operational phase,there is a need to focus on the substitution of low-carbon materials and the recycling of materials during the demolition phase,providing new insights and practical references for achieving future zero-carbon building objectives.
