项目标书摘要：建筑的生产活动在消耗资源和能源的同时也产生了大量的碳排放，因此建筑行业的节能减排迫在眉睫。目前的碳排放研究主要关注于建筑的材料生产和建筑运营维护阶段，本项目研究的重点在建筑建造与构件再利用阶段，它们是精确计量建筑全生命周期碳排放量的重要组成部分。本项目研究建筑的基本物质构成和构件分类与碳排放的关联性；研究基于建筑构件建造设计的碳排放定量优化方法；研究基于构件的建筑再利用设计与碳排放优化的关联性；研究基于建筑构件分析法的建筑全生命周期碳排放定量计算方法；研究基于碳排放优化的构件法建筑设计方法。项目在本团队已有的阶段性研究成果的基础上，优化建筑设计过程，夯实碳排放定量方法基础研究，研究目标是理清构件利用方式与碳排放量的耦合关系、以及碳排放的定量方法与构件法建筑设计的共生关系，最后形成低碳化装配式建筑的构件法建筑设计。

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.

    Climate change and resource depletion have led to the destruction of the environment, making it more urgent to address the irreversible environmental effects caused by construction industry. Life Cycle Assessment (LCA) is a systematic analytical method applied to evaluate buildings since 1990, covering every phase of buildings' whole life cycle. However, the application and influence of LCA has been restricted due to the time-consuming procedures, the high cost of software, the hysteresis and limited samples in academic studies. This research takes a light-frame industrialized housing product as a prototype, collects a variety of common building envelope materials, evaluates the life cycle energy of 1344 possible wall assemblies by using C# language, and investigates the influences of different materials. The results show that construction energy accounts for 65.97% to 68.41% of life cycle energy, which is the largest part in the whole life span, much higher than the proportion of operation energy. Meanwhile, both life cycle energy and construction energy are strongly influenced by the outer layer materials of the building's envelope, and the operation energy is closely related to the thermal insulation materials. In addition, this paper also shows a feasible methodology that could be adjusted to estimate various life cycle performance (including life cycle energy, life cycle carbon emissions, life cycle cost assessment, etc.) automatically in the architectural design stage and guide the buildings' design more effectively.
