A Framework towards Low-carbon Heritage Conservation of Hong Kong: with Analysis of Embodied Carbon
Since the industrial revolution, increasing amount of CO2 has been released due to the human economic activities. The human society attempt to find a balance in the game of protection and development, which not only protects the unique patterns and traditional way of life, but also allows the residents living here to enjoy the convenience that modern life has brought. To maintain and release the new vitality of the city, and tap the potential value and attraction, and respect the ecological environment, as well as make rational use of the advantages of the geographical environment in order to establish a green and sustainable living environment. Compared to new buildings, conservation projects can reuse the existing constructions fabric, which can reduce construction debris through the reclamation of carbon embodied in the existing materials. The paper analyzes average embodied carbon intensities and construction costs differences of the major building components between new-build projects and heritage conservations. It aims to establish a carbon cycle model through calculate-reduce-offset for the goal of low-carbon city. The authors stress that this framework can enable balanced decision-makings concerning heritage buildings redevelopment in the context of environmental and economic sustainability.
