A modified eco-efficiency (EE) framework and novel sustainability analysis methodology provides a more comprehensive view of natural and engineered system management, and it is generally applicable to industrial, environmental, and engineered systems to explore the sustainability space of alternative design configurations (see Ghimire and Johnston 2017). This methodology utilizes Life Cycle Assessment (LCA) and Life Cycle Cost Assessment (LCCA) to calculate sustainability indicators and Data Envelopment Analysis or DEA (a statistical method) to calculate the modified EE measures as sustainability scores.
Life Cycle Assessment: Life Cycle Assessment (LCA) is a comprehensive method (framework) of estimating environmental and human health (social) dimensions of sustainability consistent with the International Organization for Standardization (ISO) guidelines (ISO 2006a, b) in a cradle-to-grave approach.
ISO 14040 Life Cycle Perspective: “Entire life cycle of a product, from raw material extraction and acquisition, through energy and material production and manufacturing, to use and end of life treatment and final disposal” (ISO 2006a).
Life cycle Cost Assessment (LCCA): The U.S. guidelines for LCCA defines life cycle costs as “the sum of the present values of investment costs, capital costs, installation costs, energy costs, operating costs, maintenance costs, and disposal costs, over the lifetime of the project, product, or measure” (Register 1999).

What is Green Infrastructure?
Green infrastructure practices used in water resources management include rainwater harvesting (RWH), rain gardens, porous pavements, and green roofs.
The U.S. EPA describes Green Infrastructure as follows:
“Green infrastructure is a cost-effective, resilient approach to managing wet weather impacts that provides many community benefits. While single-purpose gray stormwater infrastructure—conventional piped drainage and water treatment systems—is designed to move urban stormwater away from the built environment, green infrastructure reduces and treats stormwater at its source while delivering environmental, social, and economic benefits.” (taken from the U.S. EPA website):
