Life-cycle Carbon Emission Calculation and Reduction Strategies for Glass Curtain Wall Hotels

Abstract

Based on the whole-life-cycle theory of building carbon emissions, this study takes a glass-curtain-wall hotel in Ganzhou City as an example, divides the hotel's life-cycle carbon emissions into five stages—material production, transportation, construction, demolition, and operation—according to its material and mechanical consumption, and conducts corresponding carbon-reduction strategy research. The results show that the material production and operation stages contribute the most to the building's life-cycle carbon emissions. As the primary targets for carbon reduction, these stages can be addressed by extending the building's service life, improving the thermal performance of the envelope, and adopting low-carbon elevators, among other measures, to achieve emission reduction goals.
