    Creating eco efficient township infrastructure projects with the use of green engineering solutions and sustainability criteria
    (Institute of Municipal Enginering of South Africa, 2015) Saroop, Shian Hemraj; Allopi, Dhiren
    Globally, the construction industry is one of the main contributors to the depletion of natural resources and a major cause of unwanted side effects such as air and water pollution, solid waste, deforestation, health hazards, global warming, and other negative consequences (Harvey and Wayne, 20084). As we face significant planetary issues such as global warming, it is clear that the engineering profession has a significant part to play in affecting the future of our planet. In order to stay competitive and to meet upcoming stricter environmental regulations and customer requirements, designers have a key role in designing civil infrastructure so that it is environmentally sustainable. These and other factors have compelled the engineer to design with greater care and in more detail. The changing roles of engineers will be highlighted, in order to react to changes in climate. Mainstreaming environmental aspects and incorporating the eco-efficiency concept into various stages of infrastructure development have not been considered as much as they should have been. Engineers need to look at greener technologies rather than just using traditional engineering solutions. This paper looks at the effects of climate change on infrastructure and the changing role of engineers. It aims to demonstrate the use of sustainability criteria on infrastructure projects. The use of the proposed criteria would ensure a sustainable design for township infrastructure services through the consideration of scare resources, ecological sensitivity in the design and planning of infrastructure projects. This paper focuses on the concept of eco-efficiency in infrastructure design that promotes the use of the greener engineering options, enabling him/her to choose the one likely to yield the best performance with the least environmental impact. It looks at a number of recommended green practices on infrastructure services design, that are environmentally sound placing, fewer burdens on the environment.

    The use of eco efficient criteria in the design of infrastructure projects
    (WITPRESS, 2016) Saroop, Shian Hemraj; Allopi, Dhiren
    Globally, the construction industry is one of the main contributors to the depletion of natural resources and a major cause of unwanted side effects such as air and water pollution, solid waste, deforestation, health hazards, global warming and other negative consequences. In the area of sustainability, there is an urgent need to apply technologies and methods that deliver better and more sustainable perfor-mance in a way that is cost-effective. Sustainability, adaptive and mitigative approaches to climate change, in the design of infrastructure, are therefore important steering elements [1]. A systematic and iterative analysis of the environmental impact of various design solutions is commonly suggested for infrastructure projects, but rarely happens. The lack of appropriate tools and skills for sustain-able design was often quoted as a barrier to sustainable design [2]. To stay competitive and to meet upcoming stricter environmental regulations and customer requirements, designers have a key role in designing civil infrastructure so that it is environmentally sustainable. These and other factors have compelled the engineer to design with greater care and in more detail. The changing roles of engineers will be highlighted, to react to changes in climate. This paper aims to demonstrate the importance of eco efficient criteria on infrastructure projects. The use of the proposed criteria would ensure a sustainable design for township infrastructure services through the consideration of scare resources, ecological sensitivity in the design and planning of infrastructure projects. This paper also gives an overview of the proposed Green Township Infrastructure Design toolkit and promotes the use of green practices on infrastructure services design that is environmentally sound, placing fewer burdens on the environment.

    Measuring infrastructure sustainability with the use of eco efficient performance criteria
    (International Association of Scientific Innovation and Research, 2015) Saroop, Shian Hemraj; Allopi, Dhiren
    Civil engineering projects can have significant site-specific and cumulative impacts on our ecological and social systems if not correctly planned, designed and implemented. As we face significant planetary issues such as global warming, it is clear that the engineering profession has a significant part to play in affecting the future of our planet. This paper aims to demonstrate the importance of eco efficient criteria on infrastructure projects. The use of the proposed criteria would ensure a sustainable design for township infrastructure services through the consideration of scare resources, ecological sensitivity in the design and planning of infrastructure projects. This paper also gives an overview of the proposed Green Township Infrastructure Design toolkit and promotes the use of green practices on infrastructure services design, that are environmentally sound, placing fewer burdens on the environment. This paper also compares two case studies that utilises green infrastructure criteria to rate its eco efficiency.

    Conceptual framework of environmental sustainable interventions with the use of green infrastructure design criteria on projects
    (2014) Saroop, Shian Hemraj; Allopi, Dhiren
    This paper presents a conceptual framework that incorporates eco-efficiency on Infrastructure projects with the use of the environmentally sustainable criteria on infrastructure projects. Mainstreaming environmental aspects and incorporating the eco-efficiency concept into various stages of infrastructure development have not been considered as much as they should have been. Engineers need to look at greener technologies rather than just using traditional engineering solutions. This paper aims to develop a framework that enables a project to be designed in accordance with environmentally sustainable criteria. The key aim of the framework was to create a more socially, economically, and environmentally sustainable neighbourhood, which focused on combating flooding, waste management, water recycling and enhancing biodiversity.

    Designing environmentally sound engineering solutions on infrastructure projects
    (World Academy of Research and Publication, 2013-12) Saroop, Shian Hemraj; Allopi, Dhiren
    There is a growing complexity of infrastructure planning and the need for coordination of design and environmental requirements. The lack of appropriate tools and skills for sustainable Infrastructure design is often seen as a barrier to sustainable design. Infrastructure development has been focused mainly on financing issues and engineering aspects in the region. Mainstreaming environmental aspects and incorporating the eco-efficiency concept into various stages of infrastructure development have not been considered as much as they should have been. Improvement in the awareness of eco-efficiency concepts is urgently needed among policy-makers, planners and decision-makers. However, the criteria applicable to, and measures for developing eco-efficient and sustainable infrastructure are yet to be fully identified (United Nations Economic and Social Commission for Asia and the Pacific, 2006). Engineers need to look at greener technologies rather than just using traditional engineering solutions. The paper focuses on the concept of eco-efficiency in Infrastructure Design that promotes the use of the greener engineering options, enabling him/her to choose the one likely to yield the best performance with the least environmental impact. This paper discussed the application of ‘green technology’ on infrastructure design projects. It gives an overview of the proposed Green Township Infrastructure Design toolkit and looks at a number of recommended green practices on infrastructure services design, that are environmentally sound placing, fewer burdens on the environment. It would ensure a sustainable design of township infrastructure services enforcing the consideration of resources, environmental impacts of design decisions, ecologically sensitivity, innovation, maintenance and materials, at the design stage of a project.
