Application Abstract: Building construction consumes a lot of resources and energy,meanwhile,generates a massive amount of greenhouse gasses.It is essential to conduct low-energy and low-carbon design practices in the construction industry.Most of the existing carbon emission studies in the construction industry focus on material production,operation and maintenance phases of the building.This project will focus on optimizing carbon emission during building construction and component reuse phases.These phases have solid impacts on calculating and measuring accurate carbon emissions throughout a building’s lifecycle.The project will determine the following:athe correlation between carbon emissions and the building material composition;bthe connection between carbon emissions and classification of building components;cthe quantitative carbon emission reduction method using component-based architectural design;dthe connection between carbon emission reduction and building components reuse design;ethe quantitative calculation method of carbon emission throughout a building’s lifecycle based on building components analysis;fthe component-based architectural design method that reduces carbon emissions.With existing research results and experiences,the project team aims to optimize architecture design process and to establish carbon emissions quantitative calculation method.The objectives of this project are:establish a clear understanding of the connection between building components utilization and carbon emission quantity;the correlation between carbon emissions quantitative calculation method and component-based architecture design;and finally,create a component-based architecture design method for low-carbon prefabricated buildings.
