Abstract Energy consumption rates have been rising globally at an escalating pace since the last three decades. The exploration of new renewable and clean sources of energy globally is thus gaining prime importance. In Australia, coal is still the primary source of energy, which, during the process of energy production, generates greenhouse gases, subsequently resulting in environmental degradation. Within this context, the paper compares the economic and environmental benefits of utilizing two renewable energy production sources: algae building technology (ABT) and solar PV panels. A case study site for retrofitting a specified area on the front facade of a multi-storied building at the University of Technology Sydney, City Campus, Australia was thus chosen for the study. A cost and benefit analysis model using the following performance indicators; return on investment, payback period as well as net present value of the two systems, was thus initiated. Annual revenue generation of both systems which included tangible and intangible benefits of both systems were simultaneously calculated. The investment and operation and maintenance costs of both systems were calculated based on market research as well as quantitative data adapted from our literature review. Our conclusions show that closed tubular photobioreactor systems have more benefit than solar panel system from an environmental impact perspective considering Australia's current struggle with water scarcity, drought, air pollution and carbon emission reduction goals.

将藻类建造技术集成到建成环境中:成本和收益的角度

摘要自从过去的三十年以来,全球的能源消耗率一直在不断上升。因此,在全球范围内探索新的可再生和清洁能源变得越来越重要。在澳大利亚,煤炭仍然是主要的能源,在能源生产过程中会产生温室气体,从而导致环境恶化。在此背景下,本文比较了利用两种可再生能源生产来源(藻类建筑技术(ABT)和太阳能光伏板)的经济和环境效益。因此,选择了一个案例研究站点,用于对澳大利亚科技大学悉尼分校的多层建筑的前立面上的指定区域进行改造,以进行研究。使用以下绩效指标的成本和收益分析模型;由此启动了这两个系统的投资回报率,投资回收期以及净现值。同时计算了两个系统的年度收入,其中包括两个系统的有形和无形收益。这两个系统的投资以及运营和维护成本都是根据市场研究以及根据我们的文献综述得出的定量数据计算得出的。我们的结论表明,考虑到澳大利亚当前在水资源短缺,干旱,空气污染和碳减排目标方面的努力,从环境影响的角度来看,封闭式管状光生物反应器系统比太阳能电池板系统更具优势。因此开始。同时计算了两个系统的年度收入,其中包括两个系统的有形和无形收益。这两个系统的投资以及运营和维护成本都是根据市场研究以及根据我们的文献综述得出的定量数据计算得出的。我们的结论表明,考虑到澳大利亚目前在水资源短缺,干旱,空气污染和碳减排目标方面的努力,从环境影响的角度来看,封闭式管状光生物反应器系统比太阳能电池板系统更具优势。因此开始。同时计算了两个系统的年度收入,其中包括两个系统的有形和无形收益。这两个系统的投资以及运营和维护成本都是根据市场研究以及根据我们的文献综述得出的定量数据计算得出的。我们的结论表明,考虑到澳大利亚当前在水资源短缺,干旱,空气污染和碳减排目标方面的努力,从环境影响的角度来看,封闭式管状光生物反应器系统比太阳能电池板系统更具优势。这两个系统的投资以及运营和维护成本都是根据市场研究以及根据我们的文献综述得出的定量数据计算得出的。我们的结论表明,考虑到澳大利亚目前在水资源短缺,干旱,空气污染和碳减排目标方面的努力,从环境影响的角度来看,封闭式管状光生物反应器系统比太阳能电池板系统更具优势。这两个系统的投资以及运营和维护成本都是根据市场研究以及根据我们的文献综述得出的定量数据计算得出的。我们的结论表明,考虑到澳大利亚目前在水资源短缺,干旱,空气污染和碳减排目标方面的努力,从环境影响的角度来看,封闭式管状光生物反应器系统比太阳能电池板系统更具优势。
